Antimicrobial formulations and solutions for food safety and quality applications are disclosed. Because some of these formulations and solutions contain a substantial concentration of salt, they are adaptable to a variety of food-processing applications, such as for chilling brine applications, disinfecting meat baths/rinses, beef injection brines, poultry chill tanks, brines used in cheese manufacture, as a wash to kill salmonella and other bacteria on hard-boiled eggs or egg shells, and as a wash to disinfect produce, which can become contaminated with salmonella and other pathogenic bacteria in the field. These uses of concentrated salt solutions that depress the freezing point of the solution provide a low temperature bath or shower in which food products can be cooled. One embodiment comprises between 25 ppm and 100,000 ppm surfactant and between 72% and 99.99% salt. This blend can then be dissolved in water to make a solution of between about 1% total solids by weight up to the saturation point, which can be used as an antimicrobial solution for food safety applications.

1. An antimicrobial composition for use in solution for food processing comprising, in combination: between about 25 ppm and about 100,000 ppm by weight surfactant wherein the surfactant comprises octanoic acid and salts thereof; andbetween about 72.5% and 99.99% salt selected from the group consist
1. An antimicrobial composition for use in solution for food processing comprising, in combination: between about 25 ppm and about 100,000 ppm by weight surfactant wherein the surfactant comprises octanoic acid and salts thereof; andbetween about 72.5% and 99.99% salt selected from the group consisting of sodium, potassium, magnesium, calcium, iron, and ammonium salts of chloride, sulfate, nitrate, phosphate, carbonate, acetate, formate, propionate, hydroxypropionate, and hydroxide. 2. The antimicrobial composition of claim 1 wherein the salt is sodium chloride. 3. The antimicrobial composition of claim 1 wherein the composition comprises, in combination: between about 50 and about 10,000 ppm by weight octanoic acid; and between about 90.0% and about 99.99% by weight sodium chloride. 4. The antimicrobial composition of claim 3 further comprising: between about 50 and about 2,000 ppm by weight octanoic acid; andbetween about 99.80% and about 99.99% by weight sodium chloride. 5. A method for food processing comprising: formulating a food product solution containing a combination of a surfactant and a salt in an amount effective to kill microorganisms;and immersing a food product to be processed in the solution;the surfactant comprising octanoic acid or a salt thereof, andthe salt being selected from the group consisting of sodium, potassium, magnesium, calcium, iron, and ammonium salts of chloride, sulfate, nitrate, phosphate, carbonate, acetate, formate, propionate, hydroxyproptonate, and hydroxide. 6. The method for food processing as described in claim 5, wherein the surfactant is octanoic acid or a salt thereof, and the salt is sodium chloride. 7. An antimicrobial solution for use in food processing comprising on a dry basis: between about 25 ppm and about 100,000 ppm by weight surfactant; andbetween about 72.5% and 99.99% by weight salt,wherein the surfactant is octanoic acid and salts thereof, and the salt is sodium chloride. 8. The antimicrobial solution of claim 7 wherein the surfactant and salt in combination comprise at least about 2% by weight of the solution. 9. The antimicrobial solution of claim 7 wherein the surfactant and salt in combination comprise about 9% to 26% by weight of the solution. 10. The antimicrobial solution of claim 7 wherein the solution comprises between about 50 ppm and about 1000 ppm by weight surfactant; andbetween about 94% and about 99.9% by weight sodium chloride. 11. An antimicrobial solution for use in food processing comprising: a surfactant comprising octanoic acid or a salt thereof, anda second salt,wherein the ratio of the second salt to the surfactant is greater than about 29:1 by weight. 12. The antimicrobial solution of claim 11 wherein the second salt comprises sodium chloride. 13. The antimicrobial solution of claim 12 further comprising at least 50 ppm octanoate acid by weight. 14. The antimicrobial solution of claim 12 further comprising at least 125 ppm octanoate acid by weight. 15. The antimicrobial solution of claim 12 further comprising at least 250 ppm octanoic acid by weight. 16. The solution of claim 12 wherein the ratio of the second salt to the surfactant is greater than about 1880:1 by weight. 17. The solution of claim 12 wherein the surfactant and second salt in combination comprise at least about 2% by weight of the solution. 18. The solution of claim 12 wherein the surfactant and second salt in combination comprise at least about 5% by weight of the solution. 19. A method for food processing comprising: contacting a food product to be processed with a solution wherein the solution comprises a combination of a surfactant comprising octanoic acid or a salt thereof and sodium chloride sufficient to substantially reduce a presence of microorganisms in the solution. 20. The method of claim 19 where the food product to be processed is cheese or a cheese product. 21. The method of claim 19 wherein the ratio of the sodium chloride to the surfactant of the solution is greater than about 29:1 by weight. 22. The method of claim 19 wherein the ratio of the sodium chloride to the surfactant of the solution is greater than about 1880:1 by weight. 23. The method of claim 19 wherein the surfactant and sodium chloride in combination comprise at least about 2% by weight of the chilling solution. 24. The method of claim 19 wherein the surfactant and sodium chloride in combination comprise at least about 5% by weight of the solution.
