    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.
