| Abstract: | Many characteristics ofpolyphenol oxidase in dioscore batatas such as optimum temperature, optimum pH value, thermostability and influence of substrate concentration, enzyme concentration, time on polyphenol oxidase activity were studied. The optimum proportion of the agent of preventive discoloration, containing ascorbic acid, citric acid, calcium chloride and sodium chloride was selected by means of L9(34) orthogonal expermental design method. This a-gent of preventive discoloration was very efficient, safe, and economical. |
