Abstract

The present invention is generally related to a product and a process to reduce the microbial contamination of processed meat and is particularly related to a product and a process to disinfect poultry carcasses using a disinfectant composition containing a fatty acid monoester, an acid or chelating agent, and a food grade surfactant. These components may be combined in either an aqueous or nonaqueous vehicle as desired. The present combination is effective against pathogenic and undesired bacteria. Advantageously, the present composition does not detrimentally alter the taste, texture, color, odor or appearance of the processed meat.

Claims

1. A disinfectant composition for use on foods consisting essentially of effective amounts of

a) a fatty acid monoester selected from the group consisting of glycerol and propylene glycol monoesters of caprylic, capric and lauric acid;

b) an acid or chelating agent selected from the group consisting of lactic acid, tartaric acid, adipic acid, succinic acid, citric acid, ascorbic acid, malic acid, mandelic acid, acetic acid, sorbic acid, sodium acid pyrophosphate, acidic sodium hexametaphosphate, and ethylenediaminetetraacetic acid and salts thereof;

c) a food grade anionic surfactant; and

d) a vehicle;

wherein the amounts of a), b) or c) in the composition either taken alone or as a combination of a) and b), a) and c), or b) and c) do not have effective antimicrobial activity and wherein the amounts of a), b) and c) in the composition taken together have effective antimicrobial activity, wherein said effective antimicrobial activity is activity against both gram-negative and gram-positive bacteria by killing the bacteria within about two minutes of contact with the composition to provide a log reduction of greater than about 5.91 when contacted with an inoculum having an initial bacterial concentration of about 10⁶ to 10⁸ cells per ml.

2. The disinfectant composition of claim 1 wherein the vehicle is selected from the group consisting of water, propylene glycol, polyethylene glycol, and mixtures thereof.

3. The disinfectant composition of claim 1 wherein the vehicle is water.

4. The disinfectant composition of claim 1 wherein the food grade anionic surfactant is dioctyl sodium sulfosuccinate or sodium lauryl sulfate.

5. The disinfectant composition of claim 1 wherein the acid is selected from the group consisting of acetic, lactic, tartaric, and mandelic acid.

6. The disinfectant composition of claim 1 wherein the fatty acid monoester is a glycerol monoester of lauric acid.

7. A disinfectant composition for use on foods consisting essentially of

a) about 0.005-1.0 wt. % of a fatty acid monoester selected from the group consisting of glycerol and propylene glycol monoesters of caprylic, capric and lauric acid;

b) about 0.01-0.5 wt. % of an acid or chelating agent selected from the group consisting of lactic acid, tartaric acid, adipic acid, succinic acid, citric acid, ascorbic acid, malic acid, mandelic acid, acetic acid, sorbic acid, sodium acid pyrophosphate, acidic sodium hexametaphosphate, and ethylenediaminetetraacetic acid and salts thereof;

c) about 0.01-0.5 wt. % of a food grade anionic surfactant; and

d) the remainder water;

wherein the amounts of a), b) or c) in the composition taken alone or as a combination of a) and b), a) and c), or b) and c) do not have effective antimicrobial activity and wherein the amounts of a), b) and c) in the composition taken together have effective antimicrobial activity, wherein said effective antimicrobial activity is activity against both gram-negative and gram-positive bacteria by killing the bacteria within about two minutes of contact with the composition to provide a log reduction of greater than about 5.91 when contacted with an inoculum having an initial bacterial concentration of about 10⁶ to 10⁸ cells per ml.

8. A disinfectant composition for use on foods consisting essentially of effective amounts of

a) a fatty acid monoester selected from the group consisting of glycerol and propylene glycol monoesters of caprylic, capric and lauric acid;

b) an acid or chelating agent selected from the group consisting of lactic acid, tartaric acid, adipic acid, succinic acid, citric acid, ascorbic acid, malic acid, mandelic acid, acetic acid, sorbic acid, sodium acid pyrophosphate, acidic sodium hexametaphosphate, and ethylenediaminetetraacetic acid and salts thereof;

c) a food grade anionic surfactant;

d) a nonionic surfactant; and

e) a vehicle;

wherein the amounts of a), b) or c) in the composition either taken alone or as a combination of a) and b), a) and c), or b) and c) do not have effective antimicrobial activity and wherein the amounts of a), b) and c) in the composition taken together have effective antimicrobial activity, wherein said effective antimicrobial activity is activity against both gram-negative and gram-positive bacteria by killing the bacteria within about two minutes of contact with the composition to provide a log reduction of greater than about 5.91 when contacted with an inoculum having an initial bacterial concentration of about 10⁶ to 10⁸ cells per ml.

9. The disinfectant composition of claim 8 wherein the nonionic surfactant is a polyoxyethylene/polyoxypropylene block copolymer.
