Abstract:In this experiment, we adopted the technology of mixed bacteria fermentation, and we used XinZhou ganoderma lucidum, flammulina velutipes as starting strains to activated training. We use the fermented liquid, aloe vera juice, stabilizers, cane sugar, citric acid, etc. According to certain deployment, homogeneous, degassing, filling and sterilization were analyzed by get the finished product. The experimental results show that: in the tanoderma lucidum, needle mixed bacteria ferment-aloe functional beverage the polysaccharide content is 2.84mg/ml, the triterpene compounds is 0.272mg/ml. Using atomic absorption spectrophotometer measured trace zinc content in the finished beverage is 0.382mg/L, the calcium content is 1.62mg/L, the lead content is 0.297mg/L, the total acid content is 0.120g/100ml. In the tanoderma lucidum, needle mixed bacteria ferment-aloe functional beverage, the soluble solids content is 10.33%. After a health inspection, the total plate count in the beverage is 2.2×104cfu/g(mL) without coliform.
