Abstract: Hericium erinaceus stains TJH-03 was used as experimental material, five drying processes were used on the Hericium erinaceus,fresh samples were dried by solar drying（SD）,vacuum freeze drying（VFD） and hot-air drying（HAD） at three different temperatures（55,65,75 ℃） and the contents of elements on nutritional labeling, amino acids, mineral elements, polysaccharide, total phenol and vitamins were determined and compared, in order to chose the best processes.The results showed that all the five drying methods could significantly change nutritional components of H.erinaceus,and HAD at 65 ℃ and VFD provide better retention of various nutrients.The nutritional components（elements on nutritional labeling, amino acids and mineral elements） in 65 ℃HAD-dried sample were better than other four drying methods, with the highest content and the best proportion.The highest contents of polysaccharide, total phenol and vitamins were found in VFD-dried sample.Compared with VFD,the contents of polysaccharide, total phenol, vitamin C and vitamin B₁ in 65 ℃HAD-dried sample decreased, but remained at about 80%.Their contents were（4.31±0.11）（405.78±6.27）（17.30±0.58）g·（100 g）^-1 and（0.76±0.02）g·（100 g）^-1,respectively.However, the time of VFD was 42 hours, which was 2.63 times of that of HAD at 65 ℃,and the process cost of VFD was expensive.Taking into consideration of product quality, drying efficiency and cost, HAD at 65 ℃ is the suitable dehydration way for industrialization of H.erinaceus dry processing.
