The present disclosure is related to antibrowning compositions for food products, for example fresh produce, and methods for using the same. In some instances, the antibrowning compositions can also prevent growth of bacteria, yeasts, and/or molds on food products.
Appearance has been shown to have a major effect on a consumer's decision to purchase foods, such as fresh-cut fruit and vegetable products. Enzymatic browning is one of the major problems affecting the aesthetic quality of fresh fruits and vegetables. The change in color during browning is due to the oxidative reactions of phenolic compounds by polyphenol oxidase and the reaction products, o-quinones, to various polymerized products. Browning not only affects color, but can also adversely affect flavor and nutritional value
Enzymatic browning can be inhibited by chemical inhibiting agents, but the use of browning inhibitors in food is limited by considerations relevant to toxicity, wholesomeness, and their effect on taste, texture, and cost. Browning inhibitors have been classified by their primary mode of action as: (1) reducing agents; (2) acidulants; (3) chelating agents; (4) complexing agents; (5) enzyme inhibitors; and (6) enzyme treatments. Sulphites, considered as reducing agents, were the most widely used, but are now subject to regulatory restrictions because of potential adverse health effects.
Currently, some antibrowning methods provide favorable results to reduce browning of food products; however, they are expensive to use and do not provide effective inhibition of microbial growth. There is a need for new compositions and methods for preventing browning and microbial growth in food products with low cost and high effectiveness.
Some embodiments provided herein provide an antibrowning composition comprising calcium ascorbate, calcium propionate, and calcium chloride.
In some embodiments, the weight ratio of calcium ascorbate, calcium propionate, and calcium chloride is about (3-25):(0.25-2):(0.2-0.3).

Methods for Antibrowning and/or Inhibiting Microbial Growth
The compositions disclosed herein can be used to inhibit browning in food products. The compositions, in some embodiments, can also be used to inhibit growth of bacteria, yeasts and/or molds in food products. For example, the antibrowning and/or antimicrobial objectives can be achieved by contacting the food products with one or more compositions disclosed herein in an amount effective to inhibit enzymatic browning and/or microbial growth.
The types of food products that can be treated by the compositions disclosed herein for inhibiting browning and/or microbial growth is not particularly limited. For example, the food products can include fruits, vegetables, tubers, seafood, beverage, and any combinations thereof. Examples of fruit include, but are not limited to apples, apricots, avocados, bananas, peaches, plums, pears, blueberries, raspberries, strawberries, blackberries, mangoes, papayas, and any combinations thereof. Examples of vegetables include, but are not limited to artichokes, beans, lettuce, bell peppers, carrots, celery, fresh spices (such as basil, rosemary, lemongrass, oregano, parsley, etc.), corn, garlic, horseradish, leeks, lima beans, mushrooms, onions, parsnips, peas, pimiento, tomato, turnips, eggplants, and any combinations thereof. Non-limiting examples of tuber include Russet, Kennebec, Hilite, Norkota and Norgold varieties of Solanum tuberosum, and any combinations thereof. The food products can be unprocessed or processed. In some embodiments, the food is freshly cut, ground, grated, pulped or otherwise processed vegetable or fruit. The fruit can be uncut or cut fresh fruit, or dry fruit. For example, the food can be slices, shreds, and dices of fruits or vegetables. In some embodiments, the food is freshly-cut apple slice. The vegetables can be uncut or cut. In some embodiments, the vegetable is lettuce or artichoke.
In some embodiments, the antibrowning composition is added to the surfaces of the food product, for example vegetable or fruit surfaces, exposed by cutting, grinding, slicing, grating, pulping or other processing to inhibit the rate of browning at the surface exposed by the processing. In some embodiments, the composition is delivered to the food product from an aqueous solution. In some embodiments, the composition is added as a solid to a liquid food, such as a vegetable juice, a fruit juice, or other beverage.
In some embodiments, the composition is in liquid form, for example an aqueous solution. A solid food, to be contacted with a composition, for antibrowning and/or microbial inhibition can be dipped or otherwise submerged in the composition, or sprayed with an aerosol containing the composition. In some embodiments, the composition is in solid form. A food can be dusted with the solid composition for antibrowning and/or microbial inhibition. For a liquid food, such as juice or other beverage, the composition (solid or liquid), can be dissolved in the liquid food. In some embodiments, the composition is dissolved in the liquid food at low levels so that no significant alteration of the taste or other sensory factors occurs.
The antibrowning and/or antimicrobial treatment of food products by the compositions can be performed under various temperatures. For example, the treatment can be performed at about 0.degree. C., about 5.degree. C., about 10.degree. C., about 15.degree. C., about 20.degree. C., about 25.degree. C., about 30.degree. C., about 35.degree. C., or a range between two of any these values. In some embodiments, the treatment can be performed under normal room temperature (that is, about 25.degree. C.).
In some embodiments, the antibrowning and/or antimicrobial treatment can further include contacting the food with one or more additional enzymatic antibrowning inhibitors.
Additional embodiments are disclosed in further detail in the following examples, which are not in any way intended to limit the scope of the claims.
Apples were washed in 100 ppm chlorine wash, and then sliced and cored into six sections using a Sunkist Sectioner model 100. Apple slices were dipped into a control solution of 5% calcium ascorbate solution and an antibrowning solution containing 5% calcium ascorbate, 1% calcium propionate and 0.2% calcium chloride for 1 to 2 minutes with agitation, respectively. The apple slices were then collected from the solutions and dried using a hand salad spinner spun at high speed for a minute. After drying, 4 to 6 apple slices were packed into micro-perforated plastic bags used commercially for sliced apples and stored at 40.degree. F. to observe the development of browning and growth of bacteria, yeasts and molds.
The stored apple slices were checked for browning and growth of bacteria, yeasts and molds at days 7, 14, 21, and 28 after being treated with the 5% calcium ascorbate solution or the antibrowning solution. Two apple slices were taken out of the bag and placed in a sterile whirl pak along with 100 ml of DI water and shaken 25 times in a 1-food arc. The resulting wash solution was diluted by adding 1 ml of the wash into 10 ml DI water and repeating this dilution to achieve the needed log reduction series, which was then plated in duplicate onto 3M Petri films to determine aerobic plate counts (APC), yeasts and molds, respectively. The number of colonies formed on the APC plates was counted after 2-3 days of storage at 35.degree. C., and yeast and mold plates were counted after 4 or 5 days at room temperature. The apple slices used for plating were discarded.

It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.
From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
