Abstract:To compared the effect of different drying methods on the quality of mushroom，the fresh dried mushroom were dried by vacuum freeze-drying，hot air drying and solar drying methods respectively.The effects of different drying methods on the quality characteristics of dried mushrooms （including shrinkage，rehydration， hardness， polysaccharide content， protein content， amino acid content and type） were investigated and the most suitable drying method for dried mushrooms was further found.The results showed that the solar drying method could better maintain its nutrient composition，the shrinkage and hardness of dried mushroom products were small，the rehydration rate was large and the drying time （7.25 h）and drying energy consumption（1.49 kW·h）were the least.Considering the cost，solar drying was the most reasonable way to dry dried mushrooms.
