Abstract:

The hot water and ultrasonic-assisted extraction processes of polysaccharides from "Xiangsi" mushroom were optimized respectively by single factor test and orthogonal test in this study. The results showed that the optimal hot water extraction conditions are as follows: material to liquid ratio 1:60, water temperature 60 ℃, and extraction time 90 min, and the optimal ultrasonic-assisted extraction conditions are as follows: material to liquid ratio 1:140, ultrasonic power 80 W, pH 8.0, and extraction time 20 min. The average polysaccharides contents of the "Xiangsi" mushroom extract by the two methods are 0.620% and 2.058%. The fomer is evidently interifior to the latter.
