Abstract
The chestnut was used to study the fresh-keeping technology.10% of the bamboo extract,0.03% natamycin and different concentrations of lac（A）,citric acid（B）,EDTA-2Na（C） were employed to measure PPO activity,POD activity,tannin content and browning degrees（BD） index by orthogonal test,then to screen the optimized film-preservative formulations.The results showed that the most optimal combination of preservation was A_1B_2C_2,which was composed of the Lac 2%,citric acid 0.2%,EDTA-2Na 0.15%,10% bamboo extract and 0.03% natamycin.The preservation during the storage process effectively inhibited PPO activity,POD activity,reducing the tannin content and browning,which reduced the incidence of browning with a good fresh-keeping effect.关键词
