UV-C irradiation could restrain the afterripening of Coprinus comatus and inhibit the activity of polyphenol oxidase during storage, accordingly reduce its respiratory strength, minish membrane permeability and delay browning reaction, especially decrease the stipe elongation rate effectively, thereby prolong its fresh-keeping time.
