Beverage manufacture and cold aseptic bottling using peroxyacid antimicrobial composition
First Claim
1. A cold aseptic bottling method for beverage containers that obtains a significantly reduced population of fungal microorganisms, said fungal organisms posing a substantial contamination risks in cold aseptic bottling, said method resulting in a sanitized beverage container, the method comprising contacting a beverage container with a peroxyacid antimicrobial composition comprising a mixed peroxyacid sanitizer comprising at least 10 ppm of peracetic acid and at least 1 ppm of a C6-C18 peroxyacid for sufficient period of time to reduce the fungal microorganism contaminating population comprising a fungal microorganism selected from the group consisting of a fungus of the genus Arthrinium, a fungus of the genus Chaetomium and mixtures thereof, rinsing the container and filling the container with a carbonated or non-carbonated beverage followed by a sealing step.

Abstract
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 much more potent biocide than can be obtained by using these components separately. 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-place” processing lines in dairies, breweries, and other food and beverage processing operations is one utility of the composition. Another utility is in processes including aseptic cold filling of beverage containers such as cans, glass bottles or two liter PET bottles.
