Study on the method using solid fermentation as raw material for health beverage.Armillaria mellea fermentation solid was used as raw material to extract the polysaccharide and other nutritional and medicinal components.After flavor adjustment,the optimum formula of the beverage of armillaria was determined through orthogonal test and sensory evaluation method.The optimizing solid fermentation medium for Armillaria mellea contained sugar 1.5%,rice 80%,soybean 1%,bran 10%,sweet potato 7.5%.The best formula for beverage was as follows:30% armillaria fermented liquid,20 g/L sugar,0.6 g/L citric acid,and 0.2 g/L xanthan gum.The ingredients of the finished product drink were as follows:0.049 mg/mL polysaccharide,0.042 mg/mL reducing sugar,53.0 mg/mL protein,and 1.226 mg/mL amino acid.The senses index,physical and chemical indexes and microbiology indicators of drink have reached national standards.The Armillaria mellea beverage has unique taste and function for health care,it has great value in utilization.
