Abstract

The invention discloses a processing method used for producing sesame oil. The processing method comprises steps of airing, milling, thermal insulation treatment, caking preparing, steaming, squeezing, and filtering. According to the processing method, sesame seeds without husks are subjected to airing so as to obtain dried sesame seeds; the dried sesame seeds are pulverized using a grinding machine, and an obtained product is sealed in a container; the product is subjected to thermal insulation treatment for 2h at 55+-5 DEG C, and is made into cakes; the cakes are delivered into a food steamer, and are steamed with water vapor; after steaming, squeezing is carried out so as to obtain coarse oil, and the coarse oil is subjected to precipitation for 36 to 48h and then is filtered so as to obtain finished sesame oil. The local flavor of the sesame oil is strong and soft; monounsaturated fatty acid content is high; long term consumption is beneficial for body health; and the sesame oil possesses relatively high nutritional value and health care effects.

Description

A kind of working method of producing sesame oil

Technical field

The present invention relates to a kind of working method of edible oil, being specifically related to a kind of take sesame as the working method of raw material production sesame oil.

Background technology

Sesame oil is a kind of food oil of Chinese tradition, and the traditional Chinese medical science is thought: sesame has effect of enriching yin beauty treatment, warming and invigorating the spleen and stomach.Modern medicine confirms: the unsaturated fatty acids be rich in sesame oil, so be more easily absorbed by the body, have protection blood vessel, delays senility, relaxes bowel, alleviates effect of tobacco and wine murder by poisoning, protection throat; Good improvement result is all had to stomatocace, periodontitis, gingival hemorrhage, throat inflammation; Meanwhile, sesame oil mouthfeel is good, fragrance is dense, and therefore sesame oil is well received by consumers, and becomes indispensable seasonings in daily life.

At present, the production method of sesame oil has water substitution, milling process.Traditional water substitution technique is: clear benevolence, moisten benevolence, fry benevolence, raise cigarette, convert slurry and stir the step such as oil, oil separation by oscillation, the sesame oil produced is with rich flavor, soft, but its labour intensity is large, and produce a large amount of waste water and can not realize continuous prodution, development is restricted.The machine that grew up afterwards squeezes technique: clear benevolence, fry seed, raise cigarette, modified, squeezing, filtration, the step such as precipitation, although compensate for the deficiency of water substitution, there is automatic control level high, can the advantage such as continuous prodution, but the sesame oil local flavor produced do not have water substitution to produce sesame oil is soft, pure.Traditional sesame oil production technique is by after parch maturation mostly, and the output sesame oil through high temperature squeezing, nutrition and the active substance of institute's produce oil can incur loss, and oil yield rate and oil all can be affected, and its natural fragrant also can be affected.

Summary of the invention

The object of the present invention is to provide a kind of working method of producing sesame oil, the sesame oil that the method is produced is with rich flavor, soft, and nutritious, can continuous prodution.

A kind of working method of producing sesame oil of the present invention, comprises the following steps:

A airing: the shelled sesame removing shell, carries out airing to it, controls water ratio 3%-5%, obtains dry shelled sesame;

B mills: pulverized by pan mill by the dry shelled sesame of step a, obtain sesame paste;

C is incubated: be sealed in container by the sesame paste of step b, under the condition of 55 ± 5 DEG C, be incubated 2 hours;

D cake: the insulation sesame paste of step c is made cake;

E boiling: be placed in food steamer by the cake of steps d, by water vapour boiling 0.5-1 hour;

F squeezes: carried out squeezing and obtaining crude oil by the sesame-send cake after step e boiling;

G filters: crude oil precipitation obtained for step f filtered after 36-48 hours, namely obtain processed oil.

In described step g, crude oil filters is evenly filtered through flame filter press, to remove impurity by crude oil.

Technique scheme has the following advantages:

The present invention is with pure natural sesame rice for prepared by raw material, does not add any objectionable constituent, belongs to green health food; The product unsaturated fatty acid content of preparation is high, and retains the beneficiating ingredients such as wheat germ phenol, phosphatide, vitamin-E, choline; Preparation process is simple, and production cost is low, and particularly processing condition are gentle, fully can retain the prototroph composition of sesame rice; Oil yield is high, and the sesame oil obtained is not containing organic solvent, and the various effective constituents in sesame oil are not damaged, and use value is higher; Except containing abundant unsaturated fatty acids, as outside linolenic acid, linolic acid, also containing various bioactivators such as plant sterol, amino acid, VITAMIN, mineral substance, especially zinc, magnesium, calcium, phosphorus content are high.

Embodiment

Below in conjunction with specific embodiment, a kind of working method of producing sesame oil of the present invention is described further.

Embodiment 1:
