PREFACE
Since early historical time food preservation has been second only in importance to food production. Grapes and other fruits were dried by the ancients to preserve them; fruit juices were fermented to make wines and vinegars; cereals and vegetables were stored to protect them against moisture and decay; olives were preserved by salting; and meats were salted, dried, and smoked.
use of sugar and vinegar in preserving fruits and came later. The preservation of foods by sterilization in sealed containers is a development of the nineteenth century and dates from its discovery by Nicholas Appert in France about 1800. Cold storage, as a
The
vegetables
of preserving all perishable products, has, during the past century, developed into a very great industry. Three billion cans of food, valued retail at $600,000,000, were sold in the United States in 1916. The meat packing and cold storage industries compare favorably with the canning industries in size. The wholesale value of the raisin crop in California is over $10,000,000 annually. The other dried fruit industries are smaller but their aggregate value amounts to many millions of dollars yearly in the United States. From this, the importance of commercial food preservation may be seen. Commercial food preservation cares for the bulk of the food products but beside the food so preserved, there are many millions of jars and cans of fruits and vegetables, glasses of jellies, jams, and marmalades and many thousands of hams and bacons " put up/ 7 by the house-
means
and farmer. Much food that would otherwise be wasted is saved and in addition a varied diet throughout the year at low cost is made available in many homes.

WHY FOOD
SPOILS
Food spoils because of the growth and destructive action of microscopic living organisms. They are com" monly termed germs." The various methods of food preservation are practically all based upon processes that destroy these organisms or prevent their growth
activity. Because they are microscopic and because they are living organisms, we shall for convenience call them " microorganisms." 1. Molds. The molding of food is a common phenomenon. In some cases the food is completely spoiled; in others, the decomposition is not sufficient to make the product inedible; and in a few products, the growth of

The spores are very light and easily detached. They are carried by the air or other agencies from place to

There are hundreds of other forms of molds but the above forms are by far the most common on food
products.
Molds are not always deleterious in their action. Camembert, Rocquefort, and some other fancy cheeses owe their distinctive quality to the growth of special forms of Penicillium molds. A form of Aspergillus

In general, molds are of interest in food preservation because of their capacity for spoiling food, their universal occurrence on food products, and the difficulty in killing their spores by heat or controlling their growth in other ways. 2. Yeasts. When a fruit juice is allowed to stand a few days it undergoes fermentation. The sugar is destroyed and alcohol and carbonic acid gas are formed. This change is brought about by another group of miYeasts are used croscopic organisms, known as yeasts. in bread making, vinegar manufacture, and in the production of various fermented beverages. Unlike molds, they do not form a mycelium, i. e., a

Milk sours on standing; meat and many cooked vegetables putrefy unless spoiling is prevented; dill pickles and sauerkraut undergo certain characteristic These changes are wholly, or in most part, changes. brought about by bacteria. They comprise the third main group of " germs " or microorganisms. Like the other two groups they are universally distributed. Bacteria are, as a rule, smaller than yeasts and differ from them in their method of reproduction. Yeasts reproduce
bacteria by splitting in two, i. e.,by" fisBacteria prefer nitrogenous substances of low acid content, such as milk, meat, peas, and beans, and do not grow readily on fruits or acid vegetables. Molds and yeasts prefer sugary, acid materials.

an enormous industry.
It has made these foods available over a longer period of the year than would otherwise be possible. Fresh meat is exported in great quan-
from South America, Australia, and the United States in ships equipped with cold storage facilities. Cold storage is principally an industrial undertaking but is used extensively in a small way by housewives and farmers in the use of the various forms of household ice chests and in the winter storage of vegetables on farms. Meat is often allowed to freeze in the winter air and is kept in a cold place till needed.

For this reason, dried fruits, meats, dried vegetables, and cereals should be stored in a dry atmosphere. Cars for the shipment of fresh fruits are well ventilated in order that moisture in excessive amounts will not collect on the fruit, and permit growth of mold. The

The temperature necessary for sterilization will depend almost entirely upon the composition of the food. Foods high in acid are very easily sterilized; those low
difficult to sterilize. This rule holds, apparently without exception. Meats, milk, and vegetables of low acidity, such as peas, corn, pumpkin, and beans are exceedingly difficult to sterilize by heat. Acid products, such as most fruits and tomatoes, are easily sterilized. On all of these products are found numbers of spore bearing bacteria of great resistance to heat; but apparently in the presence of acid they are easily killed or are not able to develop. Regardless of which theory is true, it remains a fact that acidity very positively

12. Preservation by Use of Antiseptics. Salt, sugar, vinegar acid, and lactic acid are used commonly as preservatives for foods and prevent spoiling by their poisonous action upon microorganisms. These are all harmVarious chemicals are also used as food less antiseptics. preservatives but most of them are considered harmful to health. Examples are benzoic acid, sodium benzoate,
salicylic acid, fluoride.
15
Sugar will prevent spoiling if it is present to the extent of 65%. Sirups, honey, jellies, candies, and marmalades do not spoil because they contain enough sugar to prevent molding or fermentation.
Salt
15%
must usually be present to the extent of at least to act as a permanent preservative. An apparent
exception would appear to be butter, where 5% is sufficient. But in this case, the real preservative effect of the salt takes place in the buttermilk and brine in the butter because the butter fat itself is inert and does not dissolve the salt. The liquid portion of the butter constitutes only 15% or less of the butter. Therefore* 5% of salt calculated on the weight of the butter would give a 30% solution in the liquid part of the butter. The same principle applies to other salted products. It is the salt in solution that exercises an antiseptic effect in the preservation of salted meats and salted vegetables. Vinegar acid is a more effective antiseptic than salt or sugar. For most food products 3% acetic acid is sufficient to preserve them. Vinegar is used in the presr ervation of many forms of pickles. Benzoate of soda is the most common and least harmful chemical preservative used. It is allowed by pure food laws in quantities up to one-tenth of 1%. It is used for the preservation of sirups and fruit preserves used in soda fountains and for the preservation of
ketchup.
Sulphurous acid from the fumes of burning sulphur is allowed in small quantities in food products. Other chemical preservatives are prohibited by law and are therefore of little interest to the housewife and farmer. Sulphurous acid from burning sulphur is used in fruit drying to prevent darkening. Its use for this purpose is It is universal and is permitted by pure food laws. whether the amount used is suffidoubtful, however, cient to act as a permanent preservative.
16
13. Preservation by Drying. Microorganisms that cause spoiling require a certain minimum amount of moisture for growth. If the moisture falls below this minimum in a food product the food will not spoil by molding, fermentation, or putrefaction. This principle is made use of in the drying of fruits, vegetables, and meats, and making dessicated liquids, such as dessicated
milk, dried coffee extract, etc. The amount of evaporation necessary will depend upon the composition of the food. Foods impregnated with salt need not be dried so much as those not containing

be dried to the point where the juice or sap in the dried product contains more than 65% sugar, or its equivalent in other soluble compounds. It is actually the high concentration of sugar in these cases that exerts the preservative action. This point will be reached for prunes and figs when 2}^ pounds have been dried to 1 pound; for apricots, peaches, and pears, when about 5 or 6 pounds have been dried to 1 for grapes, about 4 pounds to 1; for beets, about 7 to 1; for turnips, carrots, and tomatoes, about 14 to 1; and for onions, about 16 to 1. The ratio will depend upon the original water content This varies with the locality, of the product dried.

These are designated as fermentations, the term in^changes cluding alcoholic fermentation, vinegar fermentation, and lactic aeid fermentation. Fruit juices may be changed to wines and hard ciders by yeast fermentation.

CANNING FRUITS
Fruit canning is one of the most important of the food preservation industries. It is no longer a by-product industry, but is now a primary industry for which enormous quantities of fruit are grown annually. In addition to the fruit canned commercially, many millions of cans and jars are put up each year by housewives in the kitchen or by families who use small scale canning outfits. It is for those engaged in canning for home use or in a small way for local sale that the following discussion is intended, although the principles involved will be of interest to commercial fruit canners. The various steps in the canning process have been taken up in the order in which they occur in practice and each is discussed separately. For convenience of reference, the various topics taken up have been numbered The material in this chapter is general and serially. aims to give the principles of canning and descriptions of apparatus used rather than specific directions or recipes.

The fruit should be taken to the canning room as soon as picked. In most fruits, there is a rapid deterioration both in texture and flavor after picking. 2. Grading and Sorting. The appearance of the canned
improved by sorting the fruit according and grading for size. In home canning all grading can be done by hand and at the operator's discretion. Where large quantities of fruit are to be graded for size, the grading for size is done by mechanical

cause of their durability, their simplicity, wide openings for filling, convenience in sterilizing, and because of the fact that no metal comes in contact with the food and it is
not necessary to replace the caps, as is often the case with some other types of jars. The various modifications of the Economy jar are excellent, if their 'use is well understood. They are sealed with a lacquered metal cap carrying a composition which melts during sterilization and hardens to form an air-tight seal as the jars cool. The caps can be used only once. The ordinary Ball Mason jar is probably the most

More important than the jar is the rubber. Select rubbers of the best material. Before buying, test them, by stretching them severely. Brittle rubbers will not stand processing; they will often spread and cause leaks that result in spoiling of the contents of the jar. Rubbers
of good elasticity will often last two seasons. It is, however, a good plan to buy new rubbers each season rather than to risk spoiling through the use of old rubbers. It is
sometimes possible to use two old rubbers to each jar with good results. 3. Wax Top Cans. Three types of cans are used in

factory methods produce beet sugar of just as good quality as the best cane sugar. Both are used in commercial canneries with equally good results. A number of years ago beet sugar was in some cases
poorly refined and occasionally of poor flavor on this account. This condition no longer exists and beet sugar
can be used for canning, jelly making, preserves, marmalades, etc., to just as good advantage as cane sugar. 14. Exhausting. If fruit is put up in solder top or sanitary cans (see Recipe 1, Part III), the contents of the can should be hot when it is sealed. In commercial

boiling hot sirup or water to the fruit in the can. Exhausting or the addition of hot sirup expands the
contents of the can. The can is then sealed and sterilized. On cooling, the contents contract again and form a vacuum in the can. Hence the origin of the term " exThe vacuum formed in the can causes the hausting/' ends to be drawn in slightly. If spoiling should occur, gas is formed in the can and the edges bulge out. Thus, a can of fruit with ends slightly drawn in is known to be good. This is the principal reason for exhausting cans, or adding boiling hot sirup before sealing them. In exhausting solder top cans, the fruit and sirup are placed in the can cold. The cap is sealed on the can as directed in Recipe 1, but the vent hole is left open. The cans are placed in boiling water to about three-fourths the depth of the cans. A washboiler or other sterilizer can be used. They are left approximately five to ten minutes depending on the size of the can. They are " " then removed and the vent hole is closed or tipped with a drop of solder.

Fruits, because of their high acidity, are easily sterilized by heat; a temperature of 165 F. being sufficient.

However, since it is usually desirable to cook the fruit at the same time, the sterilization is carried out at the boiling point, i. e., 212 F. The old household method consisted in cooking the fruit in a pot and pouring it boiling hot into scalded cans or jars and sealing at once without further treatment. This method is unsafe because often the jars and caps do not get thoroughly sterilized by the hot fruit, and
spoiling results.

vegetables are more difficult to can successfruits. However, if the fundamental involved are well understood, good results principles may be uniformly obtained in canning all vegetables The difficulties of with ordinary kitchen equipment. and methods of overcoming these vegetable canning difficulties are taken up in the following paragraphs. A great deal of interest has been taken recently in vegetable canning, because of cases of fatal poisoning from the use of home canned vegetables. These poisonings have been caused by a very powerful toxin produced in jars or cans of improperly sterilized vegetables by the growth of an organism known as Bacillus botulinus. Experiments and experience have shown, however, that the methods described in this book are perfectly safe. All that is necessary is that the methods be well understood and applied intelligently.

Vegetables should usually be graded for size and appearance. The amount of grading will depend on whether the product is for home use or for sale.

In small scale canning the peeling, cutting, and preparation for the can must in practically all cases be done by hand. Root vegetables such, as beets, turnips, and carrots, may be peeled by the peeler shown in figure 43.

Several forms of steam pressure sterilizers for home use " are on the market. There is one known as the water

F. by simply opening the release cock and keeping the pressure at pounds. Steam pressure sterilizers are well suited to sterilization of cans but are not convenient for jars. In using the sterilizer, seal the cans of vegetables hot and place them in the basket or crate. Add water to the depth of several inches. Lower the crate and contents into the retort. Clamp the lid securely on the sterilizer and leave the release cock open. Heat the water to boiling and as soon as steam escapes freely from the cock close it. The purpose of leaving the cock open at first is to allow the steam to displace the air in the retort; otherwise the pressure in the retort would be due to compressed air and the temperature would be uneven and not in proportion to the indicated temperature or pressure. Heat until the dial of the steam gauge indicates the desired pressure or until the thermometer reaches the desired temperature for the required length of time by regulating the fire or by opening the release cock sufficiently, and by setting the weight on the safety valve so that it will release the steam automatically when the proper pressure is reached. When the cans have been sterilized sufficiently, open the release cock and as soon as the pressure falls to zero, remove crate and contents and cool in a tub of cold water if cans have been used. If jars are used, leave the lids and rubbers on loosely Close immediately after removal during sterilization. from the sterilizer, but do not, of course, chill the jars.
Intermittent or Three-Day Sterilization of VegeF. is accomplished by heating the container and contents to the boiling point of water for a specified length of time on several (usually three), consecutive days. It is the most effective method at 212 F., because the bacterial spores start to grow between sterilizations

from the softening effect of the heat and are easily killed by the second and third sterilizations. Cans are sealed hot and heated usually for one hour in boiling water or steam on each of three successive days. Jars are heated the first day with rubbers removed and caps on jars loosely. At the end of the first sterilization rubbers are sterilized in boiling water about five minutes, placed on the hot jars and the caps are screwed down. The second and third days the sterilizations are carried out without loosening the caps because the vacuum formed after the first day's sterilization will prevent
bursting of the jars. The three-day method is safe, but often softens the vegetables so much that they become unattractive in appearance. (c) Sterilization of Vegetables at 212 F. by One-Period Method: By this method the vegetables are heated in boiling water or steam once only, but for a long period of time. The method is recommended strongly by the United States Department of Agriculture in Farmers' Bulletin 839 and is in extensive use.
No pressure sterilizer is used with this method. It sometimes results in softening of the vegetables from Results of investigations by Dr. Dickson overcooking.

without previous cooking. By the last process the meat is not usually so attractive as where it is first cooked in some way before canning. A suitable sauce or gravy should be added. Beef is usually corned before canning (see Recipe 129) and canned with a gelatin broth which sets to a firm jelly when the meat is cooked after sterilization. Fish is ordinarily canned fresh after cutting to fit the can. Various sauces or oil may be used to fill the cans, especially with small fish such as sardines. Tomato " sauce is also used extensively. " Kippered fish is also canned. This is fish soaked in brine and smoked a short

time. (See Recipe 139.) Salmon, tuna, shad roe, are canned without added liquid.
23. Sterilization of Meats. Meats because of their low acidity, high protein content, and the presence of spore-bearing bacteria, are very difficult to sterilize. Pressure sterilizers or intermittent sterilization are very
necessary in order that fatal poisoning from botulinus bacteria may not result. Mrs. Thomas of San Francisco, now with the Extension Division of the University of California, has made experiments in which she sterilized chicken in a brine acidified with about five ounces of lemon juice per gallon. She found that the meat was The method has not easily sterilized in boiling water. been tested sufficiently to warrant a recommendation for its general use. It seems very promising, however. Meats should be sterilized under 10 to 15 pounds pressure for one heating or for !}/ hours in actively boiling water on each of three successive days. The one-period method at 212 F. is not recommended.

Spoiling of Canned Foods Botulinus Poisoning. As stated in previous chapters, spoiling is due to the growth of microorganisms. Fruits, because of their composition, are spoiled by molds or yeast. The spoiling of jars or cans of fruits usually means imperfect sealing and leaky containers, into which yeasts or molds gain access after sterilization. As the cans or jars cool after sterilization the contents contract, forming a vacuum, through which air with mold and yeast cells is drawn if the container has a
small leak.

Cans may be used for the less acid juices, such as grape and apple juices, but are not recommended for very acid berry or lemon juice, because of the danger of the solution of tin in poisonous quantities. Enamel lined cans are best and sanitary cans are to be preferred to solder top cans because of the danger from the action of the juice on the solder used in sealing the latter. Cans may be filled with hot juice at 180 F. and sealed at once without further sterilization. A better plan is to fill them with warm (not hot) juice, seal, and then

Many fruits and other substances may be used as sources of sugary liquids which may be evaporated to sirups suitable for cooking and table use. In most cases the ordinary kitchen utensils will be all that is required in the way of equipment.
33. Sources of Sirups. Maple, sugar, beet, cane, and sweet sorghum saps; grape, apple, peach, prune and some other fruit juices can all be used as sources of table and cooking sirups. They can be prepared with ordinary kitchen equipment. Such sirups will be more or less dark colored and will not be equal in flavor to the best grades of commercially prepared table sirup, but still very palatable sirups can be produced in the home. 34. Clearing the Juice. The juices should be expressed as for fruit juices. The juice should be made as clear as possible before concentration by heating to boiling for a short time with clarifying agents as described in paragraph 30 or by filtration after boiling. The clearer the juice is before concentration the more

rapidly hot than cold. 35. Deacidification. Some juices are improved for table use by removing a portion of the acidity before concentration. This is especially true of grape, sorghum, and apple juices. Precipitated chalk will combine with and remove fruit acids. It may be obtained at any drug store. The acidity must not be completely neutralized or the sirup will be very dark colored and of poor flavor. Partial deacidification is best accomplished as follows:
72
73
The cleared juice is divided into two portions, one equivalent to three-fourths and the other one-quarter of the total. To each gallon of the larger portion is added an ounce of the chalk.

The sediment may be filtered to recover the juice contained in it.

The shallower the pan, the more rapid the evaporation will be and the less the injury to flavor and color. A tin lined pan built in over a brick large rectangular furnace can be used for larger scale work. These pans are usually so arranged by partitions that the juice may be added at the upper end of the pan and sirup will flow from the lower end, the excess water being boiled off as the juice flows from the upper to the lower end. During evaporation, samples of the sirup should be taken and transferred to a tall jar and tested with a
hydrometer. A tall olive bottle or tall narrow can will answer for a hydrometer jar. The hydrometer may be purchased from any chemical supply house for about The fifty to seventy-five cents or through a drug store. The Brix druggist will usually order one on request. or Balling hydrometers ordered should read from to 70 and the Baume from to 50.

The production of both jellies and marmalades depends on the same principles, and the methods of manufacture are similar. For these reasons they have been

Other fruits are low in pectin but rich in acid; for example, rhubarb and gooseberries. Still other fruits are deficient in both acid and pectin. Peaches, apricots, prunes, pears, strawberries, and raspberries belong to this class. They must be combined with such fruits rich in pectin as currants, crab apples, or sour apples, before jelly can be made from them.

The pectin is held in the tissues of the fruit and in most cases must be liberated by boiling. Jellies can be made from currants, loganberries, and cranberries by using the juice obtained by crushing and pressing the
fresh fruit without cooking, but even these soft fruits give firmer jellies if boiled before extracting the juice.

In cooking the fruit, water must be added to the less juicy varieties, such as apples, plums, etc. Only enough should be added to barely cover the fruit; if too much is added the juice will be too dilute and failure will result. Currants, grapes, and berries need no added water. The fruits should be cooked only until tender. For apples this will be ten to fifteen minutes' boiling. Berries should only be heated to boiling. Oranges, lemons, and grape fruit are tough and require about an hour's boiling.

the fruit through a jelly bag it will be clearer than if obtained by pressure, but pressing will give a larger yield of juice and the juice will contain more pectin.
Both methods may be combined by allowing most of the juice to drain from the fruit through a jelly bag, followed by pressing out the juice from the residual pulp in a small press or by twisting the jelly bag to exert pressure. Juice obtained by pressure must be filtered through a bag several times to clear it. If this is done, very clear
bright jelly can be made from it. All fruit juices for jelly making should be made as clear as possible by straining or filtering. 41. Testing for Pectin. If any doubt as to the jelling properties of the juice exists, it should be tested for
Failure can often be averted by this test. Obtain a small amount (a ten cent bottle) of grain alcohol from the druggist.

The reason for using less sugar with fruits poorer in To make pectin is seen from the following discussion. the juice must finally contain a high amount of jelly, sugar (55 to 65%), and enough pectin and acid to form a jelly with the sugar. Boiling the juice after adding
the sugar concentrates the pectin by boiling off the excess water. The boiling must continue until the jelly contains 55% or over of sugar. The more sugar is added the less boiling is necessary and for the same reason the less concentrating of the pectin in the juice takes place. If a small amount of sugar is added, more boiling down is necessary to produce the requisite high concentration
this results in greater boiling down and of the pectin. Thus, if to a cupful of juice concentrating poor in pectin only a half cupful of sugar is added the

The fruit juice, usually equal in bulk to the fruit to be used, is boiled down to a light sirup and the fruit is then cooked down to a thick consistency in the sirup with or without the addition of sugar.

FRUIT PRESERVES AND CANDIED FRUITS
Preserves and candied products both owe their flavor, appearance, and keeping qualities to the large amount of sugar used in their preparation. Preserves are put up in a heavy sirup while candied products contain more sugar than do preserves and are packed dry. Both are expensive because of the sugar necessary and the care and time required in their preparation. Preserves are fruits or vegetables 58.

Fruit is dried in two ways: (a) by sun evaporation, and (b) by artificial heat. The former is used in dry hot climates such as prevail in California and Arizona, while the latter must often be used in climates where summer rains occur. Both methods are discussed in the
following pages.

A great deal of controversy has arisen in the past and a great diversity of opinion exists at present as to the effect of sulphurous acid in food products (sulphurous acid and sulphur dioxide are other names for the fumes It is generally admitted that when of burning sulphur). amounts of sulphurous acid are eaten in food, injury large to health results; but it is extremely doubtful whether the relatively small amount eaten in cooked dried sulphured fruits is harmful. Cooking drives off a great deal of the sulphurous acid and little remains in the cooked fruit> unless the fruit has been badly over sulphured. The sulphuring of the fruit is accomplished by spreading it on drying trays and exposing the fruit and trays to the fumes of burning sulphur for the desired length of time. The room or box in which the sulphuring is carried " " " or out is commonly called a sulphur box sulphur " house. It may be a small house large enough to hold a small hand truck or carload of trays, or may be so constructed that the trays may rest on cleats on the sides of the sulphur box. A very convenient form is the so-called " This is a light rectangular balloon sulphur hood." wooden or building paper covered box that can be set down over a stack of about one dozen trays. Sulphur is burned in a shallow pit inside the sulphur box in the ground beneath the trays, or in a container outside the box and the fumes are conducted into the box by means of a flue. To ignite the sulphur, a small amount of excelsior or a few shavings may be used. The sulphur should be kept burning constantly for the length of time it is desired to expose the fruit to the fumes. Apples are sometimes sulphured by passing them on a belt conveyor through a long box filled with sulphur fumes. Sliced apples are sulphured for twenty to thirty
minutes; apricots, peaches, and seedless grapes, three to five hours, and pears, six to forty-eight hours. After sulphuring, the fruit is ready for the dry yard or evaporator.

through is very large, the rate of absorption is greatly increased, because the air is constantly in the condition in which it most rapidly takes up water.
With these principles in mind, the artificial dryer should be built so that an even temperature, dry air, and a large supply of air are maintained. A simple dryer for home use can be constructed from a few pieces of galvanized coarse mesh screen. This is hung or placed on metal supports above the stove. The dryer consists of several of these screen trays placed one above the other at about three-inch intervals. (See
Fig. 44.)

Specific directions for temperatures of drying, etc., for various fruits will be found in recipes in Part III.
69. Sweating. Fruit dries unevenly, some pieces being hard and dry and others not quite dry enough when the bulk of the fruit has reached the desired stage of dryness. The moisture content of the outer layers of the fruit is less than that of the center of each piece. The moisture content is equalized by storing the fruit " in bins or large boxes for a time to undergo sweating," which is nothing more nor less than equalization of the moisture. The sweat boxes or bin must be protected from insects and should be kept dry and cool. The fruit is left in the sweat boxes about two weeks, or until packed for final storage or market. 70. Processing and Packing. Fruit dried in the sun usually becomes infested with insects or insect eggs which would later produce larvae with resulting loss of the fruit. Often the fruit may become too dry or may be
dusty.
110
Treatment of the fruit with boiling hot water for a short time will overcome the above defects. This may be accomplished by placing the fruit in a wire basket and
immersing it in boiling water for about one minute. If it has been very dry it may be packed at once; if only medium dry it may be necessary to allow it to dry on trays a short time before packing. Apricots, peaches, and pears are sometimes sulphured for one to three hours after dipping in hot water. This is often done to permit the fruit to absorb large amounts of water without fermenting or molding the sulphurous acid acting as an antiseptic. Its use is not to be encouraged in treating dried fruits for this
purpose.
The packing of dried fruits is an extensive industry, requiring rather elaborate and expensive machinery and a variety of processes, which cannot be described or discussed adequately in this volume. Raisins are dried to an almost anhydrous state at the packing house; are then stemmed in a special machine;
processed in hot water; and the raisins with seeds are seeded in a complicated seeding machine. Prunes are graded for size according to number per pound. The seller is paid on a basis of eighty prunes to the pound. He is penalized for all prunes requiring more than eighty to the pound and is paid a premium After for those requiring less than eighty to the pound. grading they are processed in hot water and packed.
Dried fruit for market is usually packed in paraffin paper lined wooden boxes of 20 to 50 pounds' capacity, or in paper cartons of half pound to one pound size. Packed fruit brings much better prices than bulk dried

boxes, jars, etc., can be used. Ordinary cloth or burlap bags are not suitable, because it is possible for insects to deposit eggs through these.
A dry place should be selected so that the fruit will not become moldy.

Any of the driers described for fruits under paragraph 68 may be used for vegetables. In large commercial dryers continuous systems are largely in use. The prepared vegetables pass on endless metal cloth conveyors or by screw conveyors through a drying chamber through which is circulated a strong counter current of hot air. The vegetables are handled largely by automatic machinery in order to cut down

The dried product is pressed into bales or boxes after drying to economize on shipping space. Artificial evaporators are necessary in many vegetable growing localities because of fogs and rain. In general, higher grade dried vegetable products can be made by artificial, than by sun evaporation.

(b) Yeast. Compressed yeast or magic yeast cannot be used for wine. The grapes will ferment of their own accord, but may not give a good product. If only a few gallons of wine are to be made, the grapes may be allowed to ferment with the yeast naturally occurring on them. Better results will be obtained if yeast obtained from the Viticulture Division of the University of California, Berkeley, is used. This may be obtained for one dollar per culture.

Cucumbers, green tomatoes, onions, small peppers, beets, and cauliflower are the vegetables most commonly preserved in vinegar. The processes of pickling consist of a preliminary treatment to prepare them for the vinegar and secondly, of the storage in plain or sweetened vinegar. The vinegar is the preserving agent, sterilization being unnecessary. Most vegetables for pickling (a) Storage in Brine. should be stored in brine a few weeks to remove disCuagreeable flavors before placing them in vinegar. cumbers are stored for about two weeks in a brine consisting of one and three-fourths pounds of salt to the gallon of water; this is then increased to two and onehalf pounds per gallon and the cucumbers held in this

If the salt has been removed from the vegetables by soaking in cold water the vinegar is added to the pickles boiling hot; if it has been removed by heating in water to 120 to 150 F., the vinegar is added cold. The vinegar may be spiced or sweetened by methods given in Recipe 107. The pickles will be ready for use after two or three weeks' storage in vinegar. 99. Pickling Fruits in Vinegar. Fruits, especially figs and peaches, are often made into sweet pickles by the addition of a spiced and sweetened vinegar to the cooked fruit or by cooking the fruit in this sweetened liquor.

Milk is exceedingly difficult to sterilize because of the spore-bearing bacteria present.

They may be heated in a pot of water with bottles completely immersed until the water reaches 150 F. Maintain at this temperature for twenty minutes. Remove and cool. A thermometer must be inserted in the water to test the temperature. The milk may also be pasteurized by heating in a pot to 145 F. at which temperature it is maintained for twenty-five minutes. A double boiler is best. Pour into scalded jars or bottles. For practical purposes milk may be pasteurized by heating in a pot to the simmering " scalding "; that is, heating to boiling. This point or by is often necessary for the keeping of milk in hot weather. Pasteurized milk will keep considerably longer than the unpasteurized, and will not contain living typhoid or

Butter may be kept very in cold storage, but this is rarely available satisfactorily on the farm. The most practical method for farm use is Butter should be kept cool, preservation by salting. The excluded from the air and away from the light. spoiling of butter is brought about by the formation of
may
fatty acids from the butter fat and the decomposition of the proteins and sugar in the buttermilk left in the
butter. These changes are largely bacterial in nature, although partly a simple chemical change. Exclusion of air lessens the tendency for decomposition by bacteria. Preservation by salt may be accomplished by adding from one-half to one pound of salt to each ten pounds of butter. The salt is worked in thoroughly. The butter is packed tightly in crocks and covered with salt.
152
Butter may also be preserved by adding one-fourth to one half a pound of salt to each ten pounds of butter and then storing the salt in a saturated brine (three and onehalf pounds of salt per gallon of water). This is the usual " " household method. Such butter should be freshened by working in cold water before use. Butter contains casein and buttermilk which tend to decompose. These can be removed by heating the butter in boiling water a short time. The casein is coagulated and falls to the bottom of the pot. The melted fat may be skimmed or poured off without mixing any water with it. It is then poured in dry jars, allowed to cool, and is sealed with paraffin. The butter is stored until it is to be used and keeps well in this form. It must be salted before

rather a tough curd. Seventy degrees Fahrenheit is considered the best temperature for souring of the milk. The curdled milk must next be heated to coagulate the curd. This should not be carried out at too high a temperature, or the curd will be tough and dry. The milk should be heated slowly to about 100 F., i. e., blood temperature or a little higher and kept at this temperature until the curd seems firm and the whey clear. About

Bulletin 146 of the Bureau of Animal Industry of the United States Department of Agriculture gives good descriptions of the various types. This bulletin may be obtained free of charge by writing to the United States Department of Agriculture, Washington, D. C. It is not recommended that the making of cheese (except cottage cheese) be undertaken on the farm unless in a small experimental way and with the personal advice and supervision of some one experienced in chesee making.

FRUIT CANNING RECIPES
The
following recipes contain directions for the can-
ning of the
most important
fruits.
Canning Peaches.
Pick the fruit when firm ripe. It should be canned as soon after picking as feasible. If for sale sort into three
grades for quality. These may be called Extra Fancy, Fancy, and Pie grade. The largest and most perfect fruit forms the first grade; medium size and quality, the second grade; and the soft, small, and blemished fruit is placed in the Pie grade. 2. Peel the fruit, preferably by hand. The peeling knife illustrated in Fig. 2 will be found very useful. Lye peeling is not recommended for small quantities of The skin may be slipped from fruit. See Recipe 4. some varieties of peaches after scalding in hot water and chilling in cold water.

clingstone peaches to pit around narrow side of the fruit. Insert pitting spoon at stem end, cut one-half of fruit from pit; the peach then falls in halves and the pit
may
be scooped from the adhering half by means of the pitting spoon. See Fig. 2. If the clingstone peaches are soft or difficult to pit when peeled, they should be pitted
before peeling.

Often the steels become overheated and the coating is burned off. The steel must then be heated hot enough to melt solder readily. The encrustations of burned solder must then be filed off with a sharp file until the iron surface is well exposed. The hot steel is then dipped momentarily in soldering fluid and the surface is coated " " with solder or tinned by melting wire solder against the working surface; or the filed hot steel is tinned by turning it in a mixture of crystals of sal ammoniac and small pieces of solder. The steel must be kept clean and free from carbonized sirup, corroded solder, etc., by wiping with a stiff rag and occasional filing. Disappointment always ensues when dirty steels are used.

3. Figs in Water or Light Sirup. During the rush of the season, it may be inconvenient to make the figs into preserves. If so, they may be canned in water or a 25% sirup. Pack the fresh figs into cans or jars. Cover with a hot 25% sirup (1 cup sugar to 3 cups water or pounds per gallon), or with water. Seal cans except wax top cans. Place covers and rubbers on jars and wax top cans loosely. Sterilize 1J4 hours in boiling water. Figs are very difficult to sterilize under these conditions and require at least one hour at 212 F.

JELLIES
AND MARMALADES
The recipes given in this chapter are designed primarily for the making of jellies and marmalades in the home.
Especial attention has been given to the jelly tests. These are of great value in determining when a jelly or marmalade has been boiled long enough; in determining whether a given fruit is suitable for jelly making; and in determining how to correct a fruit that has been proven by test to be unsuitable.

Crush or slice the fruit. Add water to cover unless the fruit is very juicy; for example, loganberries and currants require no water. Currants, berries, and other soft fruits are heated to boiling for not longer than 5 min. boil apples about 20 min. and citrus fruits about If the water boils off too much, add more during 1 hour. the boiling process. 3. Pour the hot fruit and juice into a jelly bag and drain off the hot juice. Press the residual pulp and keep the pressed juice separate from the strained juice. Strain the juice till clear. 4.

CHAPTER XXVII
RECIPES FOR CANDIED FRUITS
If large amounts of fruit are to be candied, Recipe 73 should be used, because it may be accurately controlled by the use of a sirup hydrometer; if only a small amount is to be made, then Recipe 74 will be found suitable, as no sirup hydrometer is needed when it is followed. Success in candying of fruit depends largely upon slow increase in the sugar content of the sirups used in candying, and in care in preventing fermentation during the candying
process.

RECIPES FOR THE DRYING OF FRUITS
The following fruit drying recipes cover both evaporaby artificial heat and by solar heat. The latter method gives satisfactory results only in climates that are free from frequent summer rains. The general printion
ciples of fruit drying will be found discussed in Chap. XII. This chapter should be read in connection with the
recipes.
Apricots, Pears, Peaches, and Apples. Apricots, peaches, and apples are allowed to ripen on the trees. Pears are picked when they are full size but still hard and are allowed to ripen in lug boxes or on piles

2. Cut apricots and peaches in half and remove pits. Peaches may be lye or hand peeled (see Recipe 2), but this is not necessary. Cut pears in half; do not peel. Peel, core, and cut apples in rings about J4 i ncri thick (see Place the fruit on trays. apple peeler, Figs. 4 and 58).

Place the trays of fruit in the sulphuring house. Place in a pan to burn for the required length of time (see time given below), 5 Ibs. per ton will be

enough for most fruits. Light the sulphur. This can be done by placing some shavings in the pan, lighting these and pouring the sulphur on them. Place the burning sulphur in the sulphur house and close the door. Expose apples to the burning sulphur fumes 30 min. apricots and peaches 3 hours and pears 6 hours. Sulphuring prevents the fruits darkening and molding during drying. 4. Place the fruit in the sun to dry. Dry until it becomes leathery and tough but not brittle. A better product will be obtained if the trays are stacked one above the other in stacks of 10 or 12 trays each when the fruit is about dry. It will then finish drying in the shade and will be of more uniform quality. 5. Sweating. Sweating consists of equalization of the moisture content.

RECIPES FOR THE DRYING OF VEGETABLES
Vegetables may be readily sun dried in most climates but the quality of sun dried vegetables is usually not so

RECIPES FOR THE MAKING OF VINEGAR
The principles of fermentation and vinegar making will be found discussed in Chapter XIV. If these principles are understood the following recipes will be much more useful. The use of good material must be emphasized; good vinegar cannot be made from partially decomposed
fruits.
Nevertheless, cull fruits, if sound, fruit peelings, cores, etc., can be used to good advantage.

5. Cover the jar or bucket, etc., with a cheesecloth so that insects will be screened out and so that air may get to the liquid freely. An abundant supply of air is necessary for vinegar formation. If a barrel is used arrange The barrel should be left about it as shown in Fig. 49. Leave the bung open two-thirds to three-fourths full. and bore a hole at each end of the barrel just above the surface of the liquid as shown in Fig. 49. Cover the holes with fine screen or cheesecloth to keep out insects. Leave in a warm place until vinegar forms. This will be in 2 to 12 months, depending on temperature condi-

By this time the juice should be deep red in color; if not, leave a few days longer. 3. Press out the fermenting red juice from the skins and stems. Place it in a cask or barrel or demijohn and leave in a warm place till fermentation is over. Then fill the barrel or demijohn with wine and place a barrel bung or cork in loosely to close it. Do not drive it in. Leave thus for about 2 or 3 weeks. Then drive the bung or cork in tightly. Leave for three weeks longer. Then draw off the wine from the sediment and transfer to other
barrels or bottles, filling them full and sealing tightly. If barrels are used they should be filled up occasionally, once a month, with wine to replace that lost by evaporation.

RECIPES FOR THE PRESERVATION OF VEGETABLES BY SALT OR FERMENTATION
Vegetables may be preserved by heavy salting with salt, by storage in strong brine and by fermentation in a weak brine or in the presence of a small amount of salt. Recipes for the use of all three methods are given. If the salting is carefully done, the salted vegetables will be very attractive in flavor and appearance. They will possess more of the fresh vegetable flavor and odor

A fire pot should be built outside the house and the smoke conducted into the house by means of a flue made of stovepipe or wood. If the meat hangs 6 or 7 ft. from the floor a fire may be built on the floor of the house itself.

Smoking. Green hickory or maple smothered in sawdust of the same wood are considered excellent for smoking pork and beef. Any hard wood is superior to soft wood. Corn cobs may be used but give off carbon that may darken the meat. Spent tan bark from tanneries is the best material for smoking fish. It is also very good for other meats. The wood should smolder and smoke and

The curd is ready to cut when it has coagulated enough to cause it to break clear over the forefinger when the finger is inserted into the curd at an angle of 45, lifted upward and touched on the top of the thumb. The curd is cut into small cubes to allow the whey to escape more quickly and perfectly. Therefore

vals until
10.
it is
sufficiently cooked.
Heating. After the cutting and the first thorough stirring, the curd should be slowly heated to about 100 F. This may be done by edging the boiler back on the stove or by pouring clean hot water directly into the boiler or vat. The whey may be dipped off and more hot water added until the desired temperature is
reached.

so firm that a handful firmly squeezed, will fall apart when released, it is ready to be removed and put to press. Draining can be done by straining through cheesecloth.
12. Pressing. When the whey and water have been drained off, the granules of curd are firmly pressed into the mold or form. If the wooden form is used, a clean piece of cheesecloth should be first laid over and pressed down into the box and then the curd pressed into all corners. When the form is filled the cloth should be folded over it, the follower head inserted, and the whole put to press, first with little pressure and later with more. If the metal form is used, the curd is first pressed in without the cloth to permit the water to escape promptly, but upon being dressed it is covered with thick, firmly

into salt as directed in the next step. 14. Salting. Salting is best done by floating the young cheese in brine made as strong as possible (3^ Ibs. of
per gallon of water). Dry salt is sprinkled on the top of the cheese and every 12 hours the cheese is turned over in the water and resalted. This is continued from 30 to 40 hours. It is then wiped dry and stored in a cool
salt
place.
Paraffining. By the old system the cheese was greased to keep the moisture in and rubbed firmly by hand every day to keep off mold, but a better way is to allow the cheese to become slightly dry and then dip into hot paraffin. A kettle filled with water, with half an inch of paraffin on the water, brought to a boil, makes an excellent paraffining tank. If the parafin is too hot, it will draw the fat out of the cheese and will not cling well. If the cheese is too moist the paraffin will not cling well. Melted paraffin may also be painted on the cheese. 16. A cellar or other fairly cool place is best for curing. If too warm, the cheese will ripen too fast and may develop an off flavor, while if too cold it will work too
