摘要
对筛选得到的S1嗜杀酵母,通过单因素试验和正交试验确定其最佳发酵苹果酒工艺条件,结果表明,糖度25%,酸度2g/L,发酵温度为20℃,接种量6%为其最佳工艺条件。发酵果酒澄清透明、具有苹果香气、酒体醇厚,酸甜协调。S1嗜杀酵母分泌的嗜杀毒素的活力与发酵温度和发酵基质pH值有关,在25℃、pH4.2时毒素活力最高。(孙悟)
Killer yeast S 1 was screened and its optimum technical conditions for cider fermentation were determined by single factor test and orthogonal test as follows： 25 % sugar content, 2 g/L acidity, fermentation temperature at 20℃ and 6 % inoculation quantity. The produced cider was clean and transparent with mellow taste and apple aroma. The activity of killer toxin secreted by S 1 was correlated with fermentation temperature and pH value of fermenting substrate （the activity was the highest as temperature at 25℃ and pH value as 4.2）. （Tran. by YUE Yang）
