Abstract
In this study, Cordyceps sinensis polysaccharide was prepared by solid fermentation with soybean meal and rice bran (1:2, W/W) as raw materials of medium. Through single-factor test, the optimum inoculation amount, fermentation temperature, water content of medium, air relative humidity and fermentation time are confirmed to be 20%, 26℃, 60%, 60% and 7 days, respectively. Fourier transform infrared spectroscopy analysis indicated that the Cordyceps sinensis polysaccharide is β-glucan.
