Claims7
A method for extending the shelf life of a food product comprising:
- treating the product with a first preparation of substantially pure glucose oxidase and a second preparation of catalase, wherein the ratio of glucose oxidase to catalase is selected so as to maximize the anti-microbial effect of the peroxide produced by reaction of the glucose oxidase prior to its destruction by said catalase;
- and packaging the treated product in a sealed package, wherein the amount of glucose oxidase added is sufficient to reduce the level of oxygen in the package to under about 1% within 5 days.
A method for treating a foodstuff for removing pathogenic organisms comprising:
- treating the product with a first preparation of substantially pure glucose oxidase and a second preparation of catalase, wherein the ratio of glucose oxidase to catalase is selected so as to maximize the antimicrobial effect of the peroxide produced by reaction of the glucose oxidase prior to its destruction by said catalase;
- and packaging the treated product in a sealed package.
