Comparative Study on Antioxidant Capacity of Self-fermenting Enzyme and Commercial Enzyme

Abstract

In order to provide consumers with a more reasonable method of using Enzyme, UV-visible spectrophotometry was used to study the antioxidant ability of self-fermenting Enzyme and commercial Enzyme. By measuring the ability of fourteen kinds of self-fermenting Enzyme and three commercial Enzyme to scavenge DPPH free radicals, superoxide anion and hydroxyl radicals and the number of living bacteria, the following conclusions were drawn: (1) Commercial Enzyme has more properties than self-fermenting Enzyme of antioxidant capacity; (2) Compound fruit Enzyme has stronger antioxidant ability than single fruit Enzyme; (3) Self-fermenting Enzyme is not sterilized including more living bacteria; (4) Commercial Enzyme has a higher drinking value than self-fermenting Enzyme.
