Abstract:According to certain proportion to prepare solid state fermentation medium of root of lentinus edodes and hawthorn leaf as main ingredient，cultivated solid-state fermentation substrates switching tuckahoe，and dryed solid yeast of the full 8 days.By ultrasonic extraction method of poria cocos-roots of lentinus edodeshawthorn leaf solid fermentationcompoungs and medium to extract total flavonoids in raw materials，the total content of flavonoids in the solid state yeast was higner than raw material content of the matrix in contrast.Functional factors such as polysaccharides，flavonoids contained in solid yeast had antioxidant，anti-aging effect. Added adequate amount of solid-state fermentation extract and raw material after matrix obtained by means of pressurized extraction to the corn oil and egg yolk，founded that solid-state fermentation extract of lipid peroxide oxidation resistance was significantly better than the raw material base.So that developed solid-state fermentation to be funtied food will have the very broad development prospects.
