Abstract

Abstract:

Enzyme is a major factor involved in the process of cell metabolism, which also contributes to food preservation. Six kinds of pollens from apricot flower, peach blossom, lotus, rape, lalayang, and sunflower contain a variety of enzymes. The activities of catalase, peroxidase, lipoxygenase, superoxide dismutase and phenylalanine lyase in 0.2 mol/L phosphate buffer extracts from these pollens were determined so that the activity level of these enzymes was used as criteria for evaluating the freshness of pollens.

Key words: pollens, enzyme, enzymatic activity
