摘　　要：从清香型酒醅中分离得到一株高产酒精酵母Y7,用于酵母麸曲制备。以麸曲发酵力作为考察指标,在单因素确定原料配比的基础上,通过响应面试验确定酵母麸曲的最佳培养条件。试验结果表明,酵母麸曲的最佳原料配比为:麸皮35 g,稻壳10 g,小麦粉4 g。采用响应面试验法进行酵母麸曲培养条件优化,得到麸曲最佳培养条件组合为:水分34%,接种量8%,培养时间48h,培养温度35℃。A high yield alcoholic yeast Y7 was isolated from fermented grains of fen-flavor liquor,and it was used for the preparation of yeast Fuqu.The fermentation strength of Fuqu was used as the index.On the basis of determining the ratio of raw materials by single factor,the optimum culture condition of yeast Fuqu was determined by response surface test.The test results show that the best raw material ratio of yeast Fuqu is bran 35 g,rice husk 10 g,wheat flour 4 g.Response surface assay was used to optimize the culture conditions of yeast Fuqu,the optimal combination of culture conditions of Fuqu was water content 34%, inoculation amount 8%, culture time 48 h, culture temperature35℃.
