Results in dicated that the complex of spermin e an d kojic acid greaùy reduced weight loss rate , delayed rot of mushroom surface ,inhibited quality deterioration ; Degradat ion rate of nutritional ingredients such as 臼corbic acid (VC) 、 total polyph enol and membrane lipid peroxidation were inhibited significanùy. The respiratory intensity and polyphenol oxidase(PPO) were inhibited ,while activity of catalase (CAT ) and peroxidase ( POD ) were enhanced ,which
