摘要
人工栽培蛹虫草所用物质主要为麦粒、大米、葡萄糖和鸡蛋,所含成分均是可食的,采摘后其残基中所剩营养物质丰富,尤其是糖类物质。以其为原料经酵母发酵可生产食用乙醇,且所得食用乙醇含有功能成分虫草素,经试验得出最佳工艺条件为:残粉60 g,水200 mL,起始pH 5.4,酵母活化液9.2 mL,30℃,90 r·min^(-1)条件下发酵7.9d。此条件下,发酵液中乙醇体积分数为12.55%,虫草素质量浓度为561 mg·L^(-1)。
Pepole usually use wheat, rice, sugar, egg material to cultivate Cordyceps militaris, and this kind of medium is edible. There are rich nutrients in the Cordyceps militaris residual mediums, especially the sugar. Yeast can use this material to produce edible ethanol, and containscordyceps, the optimum fermentation conditions is as following： the residual mediums 60 g, water 200 mL, the start pH 5.4, the activated yeast solution 9.2 mL, 30 ℃, 90 r·min^（-1） and the fermentation time 7.9 d. Under the conditions, the content of ethanol is 12.55%, and the content of cordycepin is 561 mg·L^（-1）.
