| Abstract: | The microwave-assisted hot water extraction technology for Boletus edulis polysaccharide was studied.The effects of the ratio of dried mycelia to water,microwave power,microwave time and extraction time on the extraction yield of polysaccharides were examined.The results showed that the optimal extraction conditions were ratio of dried mycelia to water l:20,microwave power 60%,microwave time 30 s,extraction time 2 h,and the extraction yield 146.2 mg/g.Compared with the traditional water extraction method,microwave-assisted hot water extraction had the advantage of higher extraction yield and less extraction time. |
