Optimization of Rehydration Process of Letinous edodes
In order to improve the quality of Letinous edodes after rehydration, the rehydration process of Letinous edodes is studied. Single factor experiments and orthogonal tests are carried out on the factors including rehydration temperature, rehy-dration time and material liquid ratio in the rehydration process. The sensory score and retention rate of lentinan after rehydra-tion are studied. The results show that the optimum condition is the redhydration temperature of 40 ℃, the redhydration time 40 min and the ratio of solid to liquid 1:40. At this time, the polysaccharide retention rate of lentinan reached 61%, and the sensory evaluation value is 24.
