Abstract: Drying mushroom is one of the effective ways of extending the mushroom life.In the process of drying mushroom,the drying dynamics characteristics and changes of drying products quality were studied by carrying out three different drying modes and two combined drying.The results showed that hot air drying was better than ordinary oven drying considering drying efficiency and dehydrating rate,and both were better than vacuum drying.However,considering the appearance quality of dried mushroom,vacuum drying was the best,then the hot air drying and the worst was ordinary oven drying. Vacuum and hot air combined drying was proven to be a effective and applicable,which had much better dried product quality than hot air dying and shorter drying period than vacuum drying.
