中文摘要: 从鸭绿江流域的北冰红葡萄果皮及其生长土壤中筛选适合酿造北冰红冰葡萄酒的耐低温、 耐高糖酵母菌,并 对其基本形态特征、 生理特性及发酵特性进行了研究。 结果表明:B④的耐糖性优于商业酵母 LB, 其在糖度 500 g/L、 pH3.0~4.0、温度 10 ℃~12 ℃时生长良好,受酒精、SO2 影响相对较小。在糖度 360 g/L 的冰葡萄汁中发酵结束后,酒精度为13.5 %vol,残糖量为 130 g/L,感官品评协调,酒体饱满浓郁,果香突出,适合冰酒生产。
Abstract:The yeasts, previously selected for their ability to bear the low temperature and high sugar form the Beibinghong grape peel and soil of the Yalu River basin, were analyzed the trait of the basic morphological characteristics, physiological characteristics and fermentation characteristics. The results manifested that the sugar tolerance of B④ was better than LB, and B④ performs best at 10 ℃-12 ℃, in the conditions of 500 g/L sugar and pH 3.0-4.0,and the affection is relatively smaller by the alcohol and SO2. The data of alcohol and residual sugar was 13.5 %vol and 130 g/L when the fermentation was stopped, which conducted in the grape must(360 g/L sugar). The sensory coordination, full-bodied flavor and aroma are the evaluations of the wine by the wine experts. B④ were identified as the most suitable yeast strains for the production of ice wine.
