【摘要】 在发酵液中添加钙、镁、锌离子可以提高淀粉出酒率,使发酵液中的残总糖明显下降。实验表明,利用早籼稻谷生料发酵生产酒精,最佳发酵温度为32℃,最佳pH为4,最佳发酵时间为120h,在最佳条件下发酵,酒分达到9.3%(v/v),残总糖为1.08%,淀粉出酒率为53.64%。更多还原

【Abstract】 Addition of Ca2+, Mg2+, Zn2+ in fermenting liquid could increase liquor yield and reduce obviously resi-dual total sugar in the solution. The experiments indicated that the optimum fermentation conditions for early nonglutinous rice to produce ethanol were as follows: temperature at 32 ℃, pH value as 4, and 120 h fermentation time. Under such conditions, alcohol content reached 9.3 %v/v, the percentage of total residual sugar achieved 1.08 %,and liquor yield of starch increased to 53.64 %. (Tran. by YUE Yang)更多还原
