Embodiment 1

[0062] Element

[0063] Mix all other ingredients (for example, fruit juice concentrate, milk powder, flavoring, sweetener, thickener, etc.) . Adjust the pH of the drink to 4.1 with citric acid, then add and dissolve potassium sorbate in the drink. A stock solution of natamycin in water was then added to the drink. The dimethyl dicarbonate was evenly dispersed in the beverage just prior to bottling (time interval from metering to bottling and capping was less than about 2 minutes). The prepared beverage is stable against microorganisms for up to 21 days at room temperature.

Embodiment 2

[0065] Element

[0066] Except for citric acid, potassium sorbate, natamycin and dimethyl dicarbonate, all other ingredients (such as fruit juice concentrate, milk powder, flavorings, sweeteners, thickeners, etc.) were mixed together to prepare a beverage. Adjust the pH of the beverage to 3.2 with citric acid, then add and dissolve potassium sorbate in the beverage. A stock solution prepared by dissolving natamycin in water was added to the drink. The dimethyl dicarbonate was evenly dispersed in the beverage just prior to bottling (time interval from metering to bottling and capping was less than about 2 minutes). The prepared beverage is stable against microorganisms for up to 21 days at room temperature.

Embodiment 3

[0068] Element

[0069]Mix all other ingredients (for example, fruit juice concentrate, milk powder, flavoring, sweetener, thickener, etc.) . Adjust the pH of the beverage to 4.2 with citric acid, then add and dissolve potassium sorbate in the beverage. A stock solution prepared by dissolving natamycin in water was added to the drink. The dimethyl dicarbonate is evenly dispersed in the beverage just before bottling (instantaneous interval from metering to bottling and capping is less than about 2 minutes). The prepared beverage is stable against microorganisms for up to 21 days at room temperature.

Abstract

Antimicrobial combinations comprising a sorbate preservative, natamycin and a dialkyl dicarbonate at levels below the taste threshold for each of these antimicrobials but such that combination is effective against food spoilage microorganisms. These antimicrobial combinations are useful in treating beverages, especially dilute juice beverages, calcium fortified beverages, beverages containing tea solids, and beverages containing milk solids and proteins, as well as other acidified, high water activity food and beverage products such as cheese, sausage, ready-to-spread frostings, salad dressings, mayonnaise, and the like, that are susceptible to food spoilage microorganisms, including yeasts such as Zygosaccharomyces bailii.

Description

[0001] technical scope [0002] The present application relates to antimicrobial compositions for beverages susceptible to food spoilage microorganisms, in particular thin juice beverages, calcium fortified beverages, beverages containing tea solids and beverages containing milk solids and protein, and Other food, etc. More precisely, the present application relates to synergistic antimicrobial compositions formulated with sub-optimal amounts of existing preservatives so as not to impart off-flavors to food products. Background of the invention [0003] The art of diluting juice drinks is well known. One ingredient that is required in order for thin juice beverages not to be refrigerated (eg, at room temperature) is an antimicrobial preservative. When thin fruit juice beverages are exposed to food spoilage microorganisms, thin fruit juice beverages can provide an environment for rapid growth of microorganisms. This exposure d...
