摘要:本实验采用混菌发酵技术,以信州灵芝、金针菇为出发株,混菌发酵,将发酵液、稳定剂、蔗糖、柠檬酸等按一定调配,经均质、脱气、灌装、灭菌得到成品,进行成分分析。实验结果表明,灵芝、金针菇混菌发酵功能性饮料感官评定,色泽、香气和滋味、组织状态、口感等良好;理化分析结果,多糖含量为3.07 mg/mL,三萜类化合物的含量为0.270 mg/mL,锌元素含量0.387 mg/L,钙元素含量1.410 mg/L,铅元素含量0.295 mg/L,可溶性固形物的含量10.10 %;微生物检验结果,混菌饮料中的菌落总数为2.6×104 cfu/g(mL),不含有大肠菌群,符合国家卫生标准。

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 3.07 mg/ml, the triterpene compounds is 0.270 mg/g. Using atomic absorption spectrophotometer measured trace zinc content in the finished beverage is 0.387 mg/L, the calcium content is 1.41 mg/L, the lead content is 0.295 mg/L. In the tanoderma lucidum, needle mixed bacteria ferment-aloe functional beverage, the soluble solids content is 10.10 %. After a health inspection, the total plate count in the beverage is 2.6×104 cfu/g(mL) without coliform
