摘要
以辽宁省建平县沙棘为材料,对沙棘酿酒酵母菌种进行筛选与试用。从沙棘野生酵母中分离筛选出8792号酵母菌株,在pH2.8～3.0仍能进行发酵,还具有抗SO_2、耐酒精度高、发酵残糖低。用以发酵沙棘酒,在25～28℃条件下发酵速度最快,凝聚性强,制成的酒具有沙棘的典型风味。
Several problems about the yeast of making seabuckthorn wine were studied.The seabuckthorns(Hippophae rhamnoides,L.)grow in Jianping county,Liao Ning province. The results showed that the 8792 yeast strain was separated and screened from wild yeast.The main property of this yeast stain was its tolerance to higher acidity.It could ferment even at pH 2.8-3.0 and its adaptable acid range was wide.This yeast stain had the characterastics of anti-SO_2,anti-alcohol and low residual sugar at the tempera- ture of 25-28℃.Its coagulation was good and the prodct had the typic seabuckthorn fla- vour.
