Abstract:
Based on the single factor experiment,the method of Box-Behnken response surface design was used to optimize the extraction process of selenium-polysaccharide in Lentinus edodes fermentation broth.The results showed that the optimum alcohol extraction time of selenium-polysaccharide was 15.45 hours,ethanol concentration 82.30% and pH 7.95.Under these conditions,the yield of selenium-polysaccharide in the fermentation broth of selenium-enriched Lentinus edodes was 3.23 g?L-1,and the selenium content of selenium-polysaccharide was 87.67 μg?g-1.Using the Box-Behnken response surface design method,the extraction parameters of selenium-polysaccharide from the selenium-enriched Lentinus edodes fermentation broth could provide the necessary technical support for the industrial production.
