    摘要:

    采用酶水解法制备肇实淀粉糖浆,并加入酿酒酵母进行发酵制成肇实发酵酒。通过单因素试验和正交试验对肇实发酵酒的液化、糖化及发酵工艺参数进行优化。结果表明:最佳肇实制浆料液比1∶10(m∶m);最佳液化条件为α-淀粉酶0.4%,温度70 ℃,时间60 min;最佳糖化条件为糖化酶0.5%,温度60 ℃,时间1 h,该条件下肇实糖化液的糖度为10.5%;最佳发酵条件为酵母添加量0.2%,温度27 ℃,时间5 d,该条件下肇实发酵酒酒精度为12.3%Vol。

    Abstract:

    The gordon euryale seed starch was hydrolyzed by α-amylase and glucoamylase to prepare starch syrup, and then the saccharomyces cerevisiae was added to prepare the health wine. The technology parameters were optimized by single factor and orthogonal experiments. And the optimal fermentation conditions were gotten. With the ratio of mass to water of 1︰10, the optimum liquefaction conditions were: addition of α-amylase of 0.4%, liquefaction temperature 70 ℃, and liquefaction time 60 min. The optimum saccharifying conditions were: addition of glucoamylase 0.5%, saccharifying temperature 60 ℃,and saccharifying time of 1 h. Under the saccharifying conditions, the sugar content of the hydrolysate was 10.5%. The optimal fermentation conditions were: yeast dosage of 0.2%, fermentation temperature of 27 ℃, fermentation time of 5 d. Under the fermentation conditions, the alcoholicity of the health wine was 12.3% Vol.
