A method for producing an aqueous equilibrium peroxylactic acid solution by reaction mixing lactic acid, hydrogen peroxide, water, one or more optional acid catalysts and one or more optional sequestering agents in a vessel over a period of time while maintaining the temperature of the solution at a temperature below about 100° C. The aqueous equilibrium peroxylactic acid solution can be used for reducing the bacterial count on a protein food product during processing.

The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.

This invention provides processes comprising contacting at least one unopened defeathered poultry carcass with water containing a microbiocidal composition, optionally opening and eviscerating at least one unopened defeathered poultry carcass that was wetted; subjecting at least one eviscerated poultry carcass to inside-outside washing with water containing a microbiocidal composition; placing at least one eviscerated poultry carcass in a chill tank into contact with chill water containing a microbiocidal composition; contacting parts of poultry resulting from processing of poultry containing a microbiocidal composition. The water in these processes contains a microbiocidal composition comprising I) one or more surfactants and II) a microbiocidal amount of a biocide. The surfactants include amine oxides and/or betaines. The biocides include various chlorine-based and bromine-based biocides; chlorine dioxide; and peracetic acid.
