BEVERAGE MANUFACTURE AND COLD ASEPTIC BOTTLING USING PEROXYACID ANTIMICROBIAL COMPOSITION

摘要

A peroxyacid antimicrobial concentrate and use composition is provided comprising a C1 to C4 peroxycarboxylic acid or a C1 to C4 peroxycarboxylic acid combined with a C6 to C18 peroxyacid in beverage processing. The combination of these materials produces a synergistic effect, providing a mu ch more potent biocide than can be obtained by using these components separatel y. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water to a pH in the range of about 2 to 8. Sanitizing of substantially fixed, "in-plac e" processing lines in dairies, breweries, and other food and beverage processi ng operations is one utility of the composition. Another utility is in processe s including aseptic cold filling of beverage containers such as cans, glass bottles or two liter PET bottles.
