Abstract
A composition for reducing deterioration and extending the shelf life of food, particularly fresh fruit and vegetables. The material will remove surface grime, farm sprays and toxins as well as reducing surface micro-organisms. Designed for home and commercial use, the composition comprises an anionic surfactant, a non-ionic surfactant, a sequestering agent, a reducing agent, a buffer and a preservative.
Description
BACKGROUND OF THE DISCLOSURE
The surfaces of food and fodder of both plant and animal origin which are-generally available are for the most part more or less seriously contaminated with both physiologically and toxicologically active noxious substances. These substances reach the food in the form of pesticides, fertilizers, preservatives, etc. Further, dirt and other noxious substances unavoidably reach the food and fodder, for example in the form of industrial emissions, fuel residues, oil fumes, and road dust, etc.
Although manual or mechanical washing or scrubbing procedure involving flowing or stagnant, cold or hot water can per se remove a portion of some of the noxious substances adhering to the surface, firmly attached contaminants and the noxious substances are either incompletely removed or not at all.
The most prominent of these noxious substances which are not removed by conventional cleaning are as follows:1. Polar pesticides 2. Nonpolar pesticides 3. Substituted and unsubstituted hydrocarbons 4. Additives 5. Heavy metals in inorganic form (oxides, carbonates, silicates,
soluble salts).
6. General contamination, including insoluble dusts and fibres.
7. Microorganisms
The environmental contamination of foodstuffs depends in a completely incontrollable manner on the condition of exposure such as weather and location, on the chemical and physical particularities of the contaminating agents and on the surface characteristics of the foodstuffs.
Further, there is the sequence of sedimentation on the surfaces of the foodstuffs exposed from the time of vegetation until the processing for kitchen and commercial use. By sequence of sedimentation is to be understood the formation of layers on the surface of foodstuffs during these periods of exposure to different elements.
SUMMARY OF THE INVENTION
The method is intended to be simple and low-cost, so that it is suitable for home and commercial food preparation and can even be used when camping and on trips. Another object of the invention is to provide agents and compositions with which thorough cleaning of foods and fodders may be accomplished.
The object of the invention is to overcome the difficulty and nuisance in the washing and freshening of the surface of foods and fodder, especially cleaning the surfaces of foods and fodder of vegetables and animal origin intended to be eaten raw, for preparation in the kitchen, or for commercial processing, said surfaces having been contaminated with e.g. physiological and toxicological pollutants, especially hydrophobic and hydrophilic biocides, inorganic pollutants, oily condensates of noxious matter and inert contaminants, by providing a method and composition serving to remove even the most stubborn adhering contaminants and pollutants, said compositions or agents being unable in manually or mechanically agitated aqueous washing solutions. The agents are simple to use, so that they are suitable for use in the home, in food processing as well as on camping and other trips.
This object can be accomplished in a method according to the invention by adding to the wash water a composition of matter and active ingredients, said composition one or more of the following substances:
Aniomic surfactants
Nonionic surfactants
Amphoteric surfactants
Sequestering agents
Buffers
Solvents - w. solvents
Reductones
Disinfectants
Stabilizers and processing additives.
Further the invention also provides agents and compositions for cleaning the surfaces of foods and fodder of plant and animal origin, said agents or compositions being added to the wash water.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
It is generally known that cleaning agents have a stronger effect at higher temperature in the cleaning bath. However, in view of individual types of perishable foods, cleaning at low temperatures, or lukewarm temperature is preferred.
The objects described above are achieved with agents of compositions of the type described herinbelow, wherein at least one substance from each of the groups below is included.
a. 1 to 10% by weight aniomic tensides, selected from the group
consisting of sulfates, ether sulfates, sulfonates, sulfoncetates,
sulfosuccinates, sarcosinates and protein condensation products.
Olefin sulfonates and lauryl sulfate are particularly suitable
because they are nearly tasteless. In particular, the solubilizing
effect of aniomic tensides favour the objects of the invention.
b. 0.1 to 4% by weight nonionic tensides, such as polyoxyethylene
adducts and polyglycosides.
Additives of nonionic surfactants serve primarily to improve coId~wettability and solubilization. When combined with aniomic
active ingredients, there is a pronounced improvement in the
cleaning power when cold. A low critical micelle formation concentration
produces a good solubilization with small amounts of additive.
Polyoxyethylene-sorbitan-fatty acid eaters in the deodorized
processing form are particularly valuable. In addition, partial
glycerin fatty-acid eaters, espectially citric acid fatty-acid
glyceride are especially suitable, these have the advantage
of being completely harmless.
c. 1 to 25g by weight sequestering agent.
Complexing of noxious elements is of great importance for the
method according to the invention. Particularly advantageous
is ethylene dimitrilotetrasoetic acid as well as salts, since
it is physiologically relatively harmless. Its metal compexes
retain sufficient stability even in slightly acid solutions
to dissolve metal oxides and other compounds, for example of
mercury, tin, nickel, colbalt, and zinc, and to keep them in
solution. In addition, the stability of ascorbic acid, still
to be discussed, is increased by masking of iron and copper.
Other suitable seqestering agents include hydoxycarboxylic acids
such as tartaric acid, citic acid, and luconic acid, as well
as D-sorbitol and mannitol.
d. 1 to 4% by weight of substances controlling the redox state; e. 50 to 30% by weight buffers.
Buffers:
The wash water advantageously should have a pH value between
5 and 8, especially about 6. This may be achieved by adding
hydroxycarboxlic acids or their alkali salts.
f. 0.1 to 0.5% by weight preservatives: g. balance up to 100% by weight composed of stabilizers, processing
additives, extenders and diluents.
h. Reductones:
It is advantageous to have a reducing aqueous medium in order
to protect the food for a short period of time against oxidative
effects during cleaning, since it affects subsequent preparation.
The colour of the food is remarkably freshened thereby, and
in the case of slightly damaged vegetables, discolouration by
chemical and enzymatic oxidation is retarded. The appearance
and aroma are precipitibly improved. Free chlorine in the wash
water, which is very harmful to aroma even when present in trace
amounts, is reduced to harmless chloride.
For example, ascorbic and ascorbates as well as sulfurous acids
and their salts are suitable as reductones for surface treatment
of foods.
i. Disinfectants:
It is not feasible to completely disinfect the surface of food
because of the nature thereof. However, it is possible to have
a nonspecific scouring of microorganisms under the influence
of washing active substances, even in the case of massive contamination.
Thus, there is possible to obtain a decrease up to 95% in the
total bacterial count on the surface of the food.
Depending on the composition employed, the addition of a preservative
may be necessary.
Tartaric acid and lactic acid, slightly disinfectant compounds,
can be added without objection. In addition, small amounts of
other known food disinfectants and preservatives may be employed
in non-toxic amounts.
In addition, the processing agents may contain sdditional components such as stabilizers, processing additives and inert fillers and diluents.
Since the solutions prepared with the agent are hypotomic with respect to cell saps, there is no danger of diffusion into the interior of the food. Owing to the relatively short processing time, mineral and organic valuable components to the food will not be loached out. It should be mentioned in this connection that the agent according to the invention is not intended to accomplish vitaminization or modification of the content of mineral salts or trace elements. By adding cold-water soluble plant and algal gums, celluose derivatives, sugar alcohols, and other water-soluble colloids, this material exchange can be further inhibited. Those compnents also have synergistic effects as dispersion stabilizers, protective colloids, anti-deposition agents, and thickeners, used alone or in combination with other components.
The processing agent can be provided in dry form as powder, granules, tablets, or pieces, in a dissolved form as paste, gel, or as an aqueous concentrate. Anhydrous preparations can be stabilized by adding colloidal nilicic acid (e.g., Aerosil 200). Potassium chloride and sodium chloride can be included for example as solid diluents.
Packaging of the agents according to the invention should receive the necessary care to keep out oxygen and prevent ultraviolet radiation from reaching the agents. Since the surfaces of foods are more or less pitted and frequently have a naturally soft consistency, the selection of the agents and compositions herein described are of particular value.
The compositions employed can be in the form of powder, granulated substances, pastes, gels, liquids, tablets, pieces or the like. As a result, multiple applications are possible.
Because of their harmless and general applicability these agents and compositions can be used in any form and without any particular instructions.
Cleaning according the the invention is particularly advantageous in the preparation of foods for freezing.
The agents and compositions according to the invention afford striking improvements in the appearance and consistency of intact, as well as aged and damaged foods in contrast to that achieved in the treatment with water alone. Discolouration during subsequent processing and loss of aroma are minimal. Lettuce, for example, which is particularly sensitive, was consistently referred to as tasting better.
The agent was used on both ordinary and exotic vegetables, provided they were left in their natural state and not cut up, including leafy and stalk vegetables, legumes, cucumbers and squash, pomaceous and stone fruits, small fruit, wild fruit, and mushrooms.
Foods of animal origin were likewise treated successfully. For example, meats and sausages, whole cheese and fish can be cleaned, where necessary.
The agent according to the invention is particularly advantageous for cleaning dried fruits, which undergo a freshening effect hitherto never achieved. Forest mushrooms lose their slime and stickiness; mushroom mycelium, pine needles, insects, and their chitimous remains are removed.
Highly sensitive types of fruit and vegetables are cleaned by a mere swishing. Very crinkly types of vegetables (for example lettuce) need no longer be taken apart to be cleaned completely.
According to the functions of the components described for the individual groups within the overall effect of the processing agent, the following general formulation is recommended for the various possible solid, semi-solid and liquid forms. The ranges given in accordance with the invention, while maintaining an overall composition which is correct for the desired function, should not be understood as strict limits::
EXAMPLE 1
Aniomic Tensides 1 to 10%
Noniomic Tensides 0.1 to 4% E.O.T.A. Disodium salt 1 to 5%
Ascorbic acid 0.5 to 4%
Sodium Disulphite 0.5 to 2%
Citric acid 1 to 12%
Tripotassium citrate 4 to 20%
Potassium carbonate 0 to 8%
Polyalcohols 2 to 20%
Preservatives O to 0.5%
Inert fillers and additives, including water 5 to 90%
In the following, sample recipes will be given for compositions of the agent according to the invention which have been found to be particularly suitable. It will be understood that the compositions may also be impregnanted in woven or non-woven textile media for introduction into wash water.

PERFORMANCE ANALYSIS
Description: A fruit and vegetable wash
Claims: To remove all farm sprays, waxes and surface grime
Dose: One capful of Veggiwash in 1 gallon of cold water (lOmL in 4500mL)
Directions for use: Wash or soak product for one minute. Rinse well.
General: The formula is presented as a concentrate to be diluted with clean tap
water. The product mixes well with water and has a mild odour. The
pH of the final solution was slightly acidic (pH 6.4). The "wetting"
properties of the dilute solution was good (235 dynes per square
centimetre).
Initial studies to define exact protocol: The claim to remove farm sprays and soiling was tested by washing
apples treated with diphenylamine and potatoes treated with
chlorpropham. It is understood that 10 to 25% of the latter can migrate
through to the flesh of the potato but we did not test for the presence
of the compound in the flesh. Our concern was to demonstrate that the
product could remove surface contaminants.
We compared peeling with washing and hoped to define a percentage
difference between before and after treatment. Washing can be defined
as taking a fresh bowl (1 litre) of tap water or diluted product at room
temperature and moving the test vegetables or fruit in the solution by
hand (can be described as a "swishing" action), for one minute. The
test vegetables or fruit were removed and allowed to drain on a mesh
grid for 5 minutes before being tested. The results were as follows:
Diphenylamine on apples
Untreated Peeled Washed/water Washed/Veggiwash 1.2mg/kg. 0.ilmg/kg. 0.96 mg/kg. 0.10 mg/kg.
90.84% reduction 20% reduction 91.7% reduction Chiorpropham on potatoes
Untreated Peeled Washedlwater Washed/Veggiwash 2.25mgtkg. 0. 125mg/kg. 2.10 mg/kg. 0.12 mg/kg.
94.4% reduction 6.7% reduction 94.7% reduction
Comments
The preliminary results indicate that there is sufficient activity to remove what may be considered to be very residual chemicals with a limited amount of washing. The product compares well with peeling the test samples but this removes much of the valuable fibre and part of the vegetable/fruit.
