    Microorganism reduction methods and compositions for food
    Fruits and vegetables, and often other food products, such as meat, are preferably washed before ingestion to remove soil and other unwanted residues that may undesirably adhere to the surface of the food. However, general cleaning methods require a cleaning step to physically remove the soil. Under many circumstances, a prepared source of pure water is not even available in small amounts for cleaning. Actually valid composition formulations, particularly those that can be safely used by individual consumers, for the production of safe and flavored fruits and vegetables for ingestion where a safe source of water is not available in abundance for cleaning, It is recognized that there are inherent problems with formulation agents because the cleaning ingredients known in the art are not completely removed and / or they do not provide sufficient antibacterial action and are therefore undesirable for use in direct contact with food. .
    Moreover, fruits and vegetables, which can be used to perform antimicrobial action and can be made into a diluted, low-sudsing liquid solution, sold in concentrated form to provide savory food without removing it It may be particularly desirable to provide effective and toxicologically acceptable compositions for foods comprising meat. Diluted liquid solutions can be applied directly by simply immersing soiled fruits and vegetables in them, which is convenient for the user to handle all areas of food. The transparency of the dilution liquid suggests cleanliness to the user, so this is highly desirable. Low foaming is an important property and any bubbles can be removed quickly and easily. In addition, the compositions described above are also advantageous when the concentrates are diluted with water which is not safe to use because the consumer often only obtains water.
    Unfortunately, many toxicologically acceptable "wash" components cannot be used with unsafe impure water.
    Summary of the Invention
    The present invention includes a method (and a composition for carrying out the method as described below) for processing agricultural products, in particular foods comprising fruits and vegetables, while maintaining flavor and without particular washing at basic pH. In the broadest aspect, the present invention provides an aqueous treatment of the surface of a food, including any detergent surfactant and a basic buffer providing a pH above about 10.5 and essentially free of any substances that adversely affect flavor.

Neutralized under the condition that the composition is essentially free of any toxicologically unacceptable material and the treatment period is at least 30 seconds, preferably at least about 1 minute, more preferably at least about 5 minutes).
    The invention described herein is intended for treating food at basic pH of at least about 10.5 by diluting from about 0.1% to about 5%, preferably from about 0.5% to about 2% by weight of the concentrated composition with water. It preferably comprises a concentrated composition comprising the following components, suitable for use in preparing a dilution composition:

    In all of the above components, if a component can be classified into one or more positions, it is classified into the first possible position. Preferably all ingredients are edible because they are ingestible.
    More particular methods of producing food products, particularly agricultural products such as fruits and vegetables, include exposing the food to dilute aqueous solutions containing potassium cations and / or sodium cations for at least about 30 seconds with a basic pH of at least about 10.5. The cations described above are preferably taken for a number of reasons. Therefore, it is preferred that they are present in the compositions used to treat foods such as vegetables and fruits without washing. Also, for soaps, potassium cations are more useful than sodium cations because potassium soaps are more soluble than sodium soaps, especially at low temperatures.
    The alkalizing method for treating foods has a pH of about 10.5 to about 13, preferably about 10.9 to about 1, using the above-described concentrated composition and impure water to provide a pure solution that kills microorganisms present on the surface of the food. 12.5, more preferably an aqueous solution prepared from a solution of about 11.3 to about 12.3, in contact with the surface of the produce. It is important to reduce the level of microorganisms on the food surface.
    Another preferred variant of the above method for treating food, such as agricultural products, is that the concentrated composition as described above is placed in a container according to the instructions for use of the composition to form the dilute solution for treating the food. Include. The above instructions are very important because the amount of dilution, treatment time, elimination of the need for cleaning and the use of impure water to form the treatment solution are not intuitive. It is also desirable to use pictures and / or icons because the instructions are as simple and concise as possible.
    The balance of the composition may include any of a variety of auxiliary substances, pH adjusting agents, fragrances or essences, preservatives, antifoaming agents, and the like.
    The components in the above-described concentrated compositions are preferably "edible grade" and are selected and used in proportions to provide a substantially clear dilution composition. "Substantially transparent" includes minimal turbidity, preferably that the composition is completely transparent. The components are also chosen to have a minimal odor at the beginning or after storage. The removal of odors is inherently important in compositions for use in foods.
    In order to block any unpleasant odors, the composition may comprise an edible grade or GRAS (hereinafter defined) fragrance or essence component. Especially preferred for this use are oils derived from citrus fruits containing relatively large amounts of terpenes, for example oranges, lemons, limes, grapefruit, tangerine, tangelo and the like.
    Preferred compositions for use herein include only those materials of edible grade or GRAS that include, of course, direct food additives identified as GRAS to prevent the possibility of misuse by the consumer. Traditionally, most proposals for washing fruits and / or vegetables typically take into account the commercial scale of controlling the conditions, in particular their amount, through washing. The present invention includes inherently providing extra safety to the product even when used by individual consumers without cleaning. If it is insufficient to clean thoroughly after washing, then it is not a big problem if all ingredients are GRAS and / or food grade.
    The use and selection of cleaning ingredients for cleaning fruits and vegetables is described in Title 21, part 173.315 of the United States Code of Federal Regulation, "Ingredients for use in cleaning or alkaline peeling of fruits and vegetables. washing or lye peeling of fruits and vegetables). The above rules limit the ingredients that can be used to make direct contact with foods, described as "generally regarded as safe" (GRAS), and some other selected ingredients. The above section also provides certain limits on the amount of material that can be used in a given context. However, there are no provisions or restrictions on how to produce foods that are safe to consume using aqueous compositions that do not need to be removed. In addition, methods of killing microorganisms using small amounts of substances such as hypochlorite, iodine and the like, which provide a desirable flavor, are not known.
    All documents cited herein are hereby incorporated by reference.
    The present invention provides a method of producing food, in particular a method of producing agricultural products that are safe for human consumption while maintaining the palatability of the food when a sufficient amount of pure water is not available for rinsing the food. A liquid composition particularly suitable for carrying out the process, in particular concentrated or correspondingly diluted.
    The following toxicologically acceptable ingredients are used to prepare the preferred compositions herein. "Toxicologically acceptable" means that any residue from the components of the composition that may remain in the fruit or vegetable washed with the composition is safe for human and / or lower animals to ingest.
    Detergent surfactant
    Synthetic Anionic Surfactants:
    Base stable anionic surfactants may be used as permitted in the United States as Title 21, part 173.315 in the US Federal Regulations Code (CFR). Particular mention may be made of salts of dodecylbenzene sulfonate, usually at concentrations of up to 0.2%. Phosphate esters of ethylene and / or ethylene / propylene oxide adducts of aliphatic alcohols, dioctyl sulfosuccinate and 2-ethylhexyl sulfate are also described in the CFR.
    Anionic surfactants are preferably materials known in the art, for example C 6-18 alkyl sulfates and / or sulfonates; C 6-15 alkylbenzene sulfonate; Di-C 6-10 alkyl sulfosuccinate. In terms of antimicrobial efficacy and flavor, alkyl sulfates are particularly preferred as sodium and / or potassium salts. Potassium C 8-14 soap is also preferred. Mixtures of the foregoing alkyl sulfates and soaps are also preferred.
    Nonionic Surfactants:
    If a nonionic surfactant is used, it is a substance known in the art, for example, alkylene oxide (ethylene oxide and / or propylene oxide) adducts of C 10-18 aliphatic alcohols or acids, glucose (alkyl polyglucosides) C 10-18 aliphatic alcohol adducts. Ideally, the particular nonionic surfactant selected will have a hydrophilic-lipophilic balance (HLB) of greater than about 10 in the composition and a cloud point of at least about 35 ° C. The US Federal Regulations Code (CFR) specifically describes ethylene oxide / propylene oxide adducts of C 12-18 aliphatic alcohols having a molecular weight of about 800. Such materials are commercially available as PLURAFAC RA-20 (BASF).
    In compositions comprising soaps, the alkoxylated alcohols serve primarily as dispersants for any soap coagulation that may form during the washing process. It is also recognized that non-nitrogen containing nonionic compounds can be selected to minimize the growth potential of bacteria in diluted surfactant compositions.
    Fatty salts:
    The compositions herein may comprise soaps, in particular C 8-14 soaps, such as coconut fatty acid cut soaps. Lauric acid is convenient for this purpose. Higher proportions of certain solubilizing surfactants can be used to dissolve the soaps described above. However, soap should not be used in large quantities because it is a taste to be taken into account.
    The presence of detergent surfactants is primarily important for reducing surface tension and viscosity. It is preferred that the dilution treatment composition usually has a low viscosity of less than about 50, preferably less than about 10, more preferably less than about 5. Low viscosity improves the completeness of the treatment, particularly by promoting dispersion on the surface of foods with layers, wrinkles and the like. Low viscosity also improves drainage and removes at least some dirt. Low viscosity also improves the drying rate in some cases. Thus, detergent surfactants provide a very important advantage in terms of treatment.
    Detergent surfactants also improve antimicrobial action. The presence of surfactants, especially alkyl sulfates, provides improved killing and / or killing rates.
    It is important that the detergent surfactant does not affect the flavor. Therefore it should be low concentration. As discussed above, soaps are generally not used in large quantities because of the taste considerations, and edible grade surfactants are highly desirable when taste is considered.
    Alkaline Buffer:
    Toxicologically acceptable basic buffers are used in the compositions of the present invention to maintain the pH of the product in the desired range. For ease of formulation, it is often preferred that the basic buffer described above is in potassium salt form, especially in liquid concentrates. Sodium salts are acceptable, more preferably solid, for example powder formulations. Potassium / sodium carbonate and / or potassium / sodium ortho-phosphate are convenient and preferred basic pH buffers. In particular, where the composition does not contain calcium ion sequestrants, calcium and / or magnesium hydroxide can also be used to generate basic pH. Sodium and potassium hydroxides can be used as part of the alkaline buffer system. Dilution product having a preferred viscosity as described above, for example, less than about 50 cps, preferably less than about 10 cps, more preferably less than about 5 cps under shear of at least about 1000 sec −1 by controlling the amount and consistency of the components To provide.
    The pH preferably does not exceed about 13 and does not include a higher amount of buffer at higher pH, especially for the safety of the consumer, if the composition is not completely removed. The preliminary alkalinity should be about 0.1 to about 10, preferably about 0.2 to about 7, more preferably about 0.3 to about 4.
    Metal Ion Containers / Builders:
    Preferred metalion sequestrants and / or builders herein are polyphosphate salts or organic polycarboxylic acid salts, such as sodium and / or potassium citrate, and sodium and / or potassium ethylenediaminetetraacetate, which are commercial standard items and are GRAS. . In particular, other organic polycarboxylic acids which are GRAS, such as citric acid, tartaric acid, malic acid and the like can be used. A preferred form of polyphosphate is Fast Dissolving STPP available from FMC Corporation. Complex phosphates can also be used, which are very useful for maintaining the transparency of dilute solutions prepared from hard water, but are generally avoided in view of regulations where the amount of phosphate is specifically prohibited or very limited. Typically, the metal ion sequestrant / builder is in an amount of from about 0.0005% to about 3% by weight, preferably from about 0.005% to about 0.5%, more preferably from about 0.01% to about 0.2% by weight of the diluent composition. Exists as. Metal ion sequestrants / builders can maintain the efficacy of the formulation in the presence of hard water.
    antiseptic:
    Formulating the concentrated compositions of the invention at high pH reduces the tendency of biological growth of contaminants such as bacteria, fungi or fungi. However, preservatives can help ensure lack of biological growth through contaminants in manufacture or use. Standard food grade preservatives such as, for example, ethylenediaminetetraacetic acid and / or salts thereof may be used in amounts of about 0.01% to about 0.2% of ethylenediaminetetraacetic acid or its sodium and / or potassium salts, but generally The basic pH composition does not require preservatives.
    Fluid carrier:
    Most of the dilution compositions herein, for example about 2/3 or more (typically about 80-99.7 weight percent), comprise water as the solubilizing carrier for the components. As will be appreciated later in the examples, water-ethanol can also be used, which is particularly desirable when formulating the basic pH compositions herein. The amount of ethanol in the dilution composition should preferably not exceed 2% in the solution used to treat the produce to avoid alcoholic odors. Other compatible water soluble low molecular weight solvents such as glycerol may also be used. Glycerol can also be used in solid compositions to minimize micronization. An advantage of the present invention is that impure water can be used to prepare diluent compositions, and that microorganisms can be killed by high pH and / or surfactants and / or builders. As used herein, "impurity water" means water that is not pure because of the microorganisms present.
    Optional Ingredients:
    Polyethylene glycol:
    The water soluble polyethylene glycol polymers (PEG) used, which can be used herein, are known as commercial products and are available, for example, under the various product names of CARBOWAX (commercially available from Union Carbide Corporation). have. PEG having an average molecular weight in the range of about 200 to about 20,000 can be used herein, and PEG having a mean molecular weight of at least about 200, usually 300 to about 9500, as carbowax is convenient and preferred. The dilution composition herein may comprise at least about 0.001% PEG by weight, and typically may comprise from about 0.005% to about 0.1% PEG by weight. The amount used may vary with the choice of formulation agent, depending on factors such as the molecular weight of PEG, the amount of surfactant used in the composition, the desired viscosity of the composition, and the like.
    In a conventional form, preferred compositions herein with improved tactile feel comprise a surfactant / PEG weight ratio in the range of about 1: 2 to about 30: 1, preferably about 1: 1 to about 15: 1.
    Compositions herein comprising polyethylene glycols are characterized by their excellent cleaning performance and foaming / cleaning properties as well as their improved “feel”. The improved feel of the composition in contact with the hand of the user is a qualitative touch. However, "non-slip" and "non-soap" improvements in skin feel can be demonstrated by friction test (with PEG) and control (PEG free) composition tests inside the support scorer's hands or arms. Even in the basic test described above, the scorer can easily distinguish the improved feel of the composition.
    Antioxidant:
    The use of surfactants, especially soaps, can be complicated by the development of unpleasant odors and / or yellowing of the compositions they represent. These undesirable properties are believed to be caused primarily by complex side reactions initiated by the reaction of oxygen with the polyunsaturated component of the fatty acid stock solution. These results can be avoided or minimized by avoiding contact with air or by controlling the quality of the fatty acid stock to minimize the amount and type of polyunsaturated as described above and / or add chelating and / or antioxidants. .
    The addition of tocopherols (such as vitamin E or tocopherol acetate) to alkaline formulations has been found to be advantageous because they do not degrade or impart intense color. For a prolonged period of time they especially inhibit the development of unpleasant odors for high quality oleic acid stocks as described above to minimize or eliminate the need for odor barriers. It is also useful to use butylated phenols such as BHT and BHA, but their effectiveness is shown to be more limited and to impart intense color to the composition. Other food grade antioxidants (such as vitamin C, sorbate, and sulfite) preferably prevent the degradation of the composition by oxygen action, but vitamin C can be problematic in color degradation, and sulfite is an odor problem. Use with caution because it can cause it. Sulfite is also a target of potential health problems.
    Antifoaming Inhibitors (Silicon and Derivatives thereof):
    Small amounts of antifoaming agents or antifoams may be used, especially where certain amounts of surfactant are desirable for wetting and / or efficacy, but it is desirable that the degree of foaming resulting from washing the produce is kept low. The amount of antifoaming agent can be controlled in terms of the type and amount of surfactant used. Dow Corning commercially available DC-4270 and DC2-4242 are useful as antifoaming agents.
    Such PEGs can optionally be used as carriers or builders for silicone foaming inhibitor particles in anhydrous powder concentrate formulations. Usually the PEG molecular weight is the amount by which PEG is a solid at room temperature to contain silicone. In this case, the preferred molecular weight is 8000. If PEG is the complete part of the carrier for the silicone in the powder concentrate, care must be taken to treat the material to avoid excess shear of the anhydrous product. PEG should be sufficiently soft so that the excess shear can change the integrity of the particles formed with it.
    Mild Incense:
    Odor ingredients may be used in small amounts in the concentrate. They can give a concentrated favorable flavor but dilution makes it unrecognizable in solution or in the treated product.
    Typical Halogen Antibacterials:
    One advantage of the present invention is that there is no need to use hypochlorite or iodine as a means to reduce the microbial community. It is known that these materials have an undesirable taste and can add to environmental pollution. However, it is often desirable to have a source of iodine which has a small amount of hypochlorite, typically lithium, sodium, potassium, calcium and / or magnesium and / or which is present in small amounts to further kill the microorganism.
    usage:
    The concentrated compositions herein are preferably used to place them in a container (eg a pan) with water, preferably pure water, to form a dilution composition and to facilitate dipping of food.
    Typical uses include treating individual food products in a "bath" and then draining and / or drying the food to minimize the amount of composition remaining in the food.
    In any process for using the dilution compositions described herein, the food product is washed and rubbed and / or wiped with a suitable cleaning material (eg cloth, sponge, paper towel, etc.). In any other process, the potentially impure water is treated with a concentrated composition to kill microorganisms and this “treated” water is used to clean the food treated with the diluted treatment composition in another container. This protects against undetectable gradual contamination of the original treatment composition. Since the "wash" composition may contain small amounts of concentrate, all that is needed can kill the microorganisms of the water itself.
    Surprisingly, the compositions and methods described herein can provide effective disinfection / hygiene. In order to provide good killing of microorganisms (especially bacteria), high concentrations and / or longer exposure times must be used. Typically the diluent composition should be used in complete concentration and remain in the food for at least about 30 seconds, preferably at least about 1 minute, even more preferably at least about 5 minutes, even for some microorganisms even 10 minutes are required. May be Longer exposure times (e.g., contact time between product and bacteria) provide better antibacterial benefits. The importance of time depends on both the pH of the product and the formulation concentration. At high pH (above 11.5) and high concentrations, antimicrobial efficacy is achieved quickly. Lower pH values (below 11.0) and lower formulation concentrations require longer exposure times to achieve the same efficacy.
    Generally higher pH is advantageous
    The process herein forms a dilution treatment composition using (a) pure water and / or (b) impure water, followed by (1) removal of any residue by mechanical means, absorption and / or drainage without washing. ; (2) where impure water is available, which may be cleaned using it and / or (3) treating the impure water with a dilution treatment composition to produce a "pure" wash water which is then washed.
    food:
    It can handle all kinds of food. Examples thereof include agricultural products including fruits and vegetables to be consumed after the treatment, such as apples, grapes, peaches, potatoes, lettuce, tomatoes, celery and the like; And meat, seafood and poultry, including but not limited to edible animal proteins, in particular foods comprising proteins found in the above food sources, for example beef, pork, chicken, turkey meat, fish, crustaceans And game meat (eg, venison, rabbit meat, etc.). Such edible animal proteins include processed forms of the aforementioned protein sources, including but not limited to ground ground beef, ground turkey meat, bolognese, hot dogs, sausages, fish cakes, and the like. The food is preferably prepared for tasting after treatment and consumed immediately thereafter to minimize recontamination.
    The compositions may also be washed on non-food items (e.g., any surface not used as food, even surfaces that do not come into contact with food), inanimate, utensil surfaces, especially on food production or other food contact surfaces (surfaces in contact with food). (Especially for stain removal), disinfection or sanitizing. Examples include cutting boards, kitchen countertops, kitchen containers, tableware, strainers, sinks, sponges, towels, cloths, cloth napkins (napkins), tablecloths, and other surfaces in contact with food. The surface is preferably sterilized / hygienic before contact with food, and preferably re-sterilized / hygienic where the surface is recontaminated. The products of this disclosure, which include all GRAS and / or food grade ingredients, are optimal for this purpose. Of course, on a hard surface, after sufficient time has elapsed, the composition can be removed by washing it with pure water, if available, or by absorbing and wiping with an appropriate object (e.g. paper towel, sponge, squeegee, etc.). have.
    The compositions of the present invention are also used for treating / cleaning non-living utensil surfaces of other non-food items, such as fabrics (eg clothes, shoes and shower curtains), in particular baby articles (especially toys, diapers (napkins) and bibs). Can be used. Contaminated fabrics can be disinfected / hygienic and then drained and / or dried, minimizing the risk of infants putting fabrics or other products in their mouths. However, it is desirable to wash the fabric with at least low alkalinity water. The fabric may be treated in its entirety or in a particular portion, and then preferably at least partially removed the composition, for example by drainage, absorption and / or mechanical forces.
    In order to provide disinfection / hygiene, packaging of the product herein in a container with instructions for the time and proper dilution is provided to the individual consumer by providing information on the proper use to remove / kill the microorganisms. Will help. It is a particular advantage that the product can be used for this purpose at a suitable time in a food production method that minimizes recontamination. The instructions ensure that no cleaning is necessary to prevent possible re-contamination, preferably by cleaning with impure water.
    In the case of fabrics, the pH of the composition is preferably about 11.5 or less, more preferably 11.0 or less.
    In the case of fabrics and hard surfaces, the distribution of the compositions of the invention can be achieved by using spraying devices, rollers, pads and the like or by immersing them in the bath of the composition. Spraying is the preferred method.
    All parts, percentages, and ratios herein are by weight unless otherwise indicated. All values are approximate unless otherwise noted.

Illustrative basic liquid dilution treatment compositions can be prepared at pH 10.5-13 by dissolving the concentrated composition or individual components in water or water-ethanol using conventional mixing equipment. In the conventional form, for example the concentrate of Example 1, water is placed in a treatment vessel. Potassium hydroxide, ortho-dipotassium phosphate, disodium EDTA, ethanol and surfactant (lauric acid) are added with stirring in the specified order. Any aromatic component (grapefruit oil) can be added at any time after the surfactant has been dissolved in the mixture.
