摘    要:目的]为生产优质清酒奠定理论基础。方法]以优质粳米为原料,在单因素试验的基础上。采用正交试验法研究耐酸性清酒酵母A的发酵规律。结果]水料比为1—2时,清酒酒精度较高。水料比为0.5时,发酵醪的糖浓度和渗透压较高。水料比为3时,发酵醪的淀粉浓度降低,清酒酒精度低。酒母量为20%时,利于清酒双边发酵,清酒的可溶物含量约为11%。米曲量为30%~50%时,清酒色度低,苦涩味轻。乳酸添加量为8‰~12‰时,发酵结束后米曲中糖化酶的活力约为290mg/(g·h)。乳酸量超过12‰时,酶活力下降比较快,清酒有异杂味感。15℃下发酵21d的清酒酒精度达17.1%(V/V),淀粉利用率为88.1%。结论]利用耐酸性清酒酵母发酵生产清酒,简化了生产工艺,缩短了发酵时间,提高了原料利用率。

关 键 词:清酒  清酒酵母  发酵参数  正交试验

Abstract:Objective] The purpose of the study was to lay a theoretical foundation for producing high-quality sake.Method] With high-quality round shaped rice as raw material,on the basis of single factor experiment,the fermentation law of acid-resistant Saccharomyces sake A was studied through orthogonal experiment.Result] When the water-material ratio was 1-2,the alcohol degree of sake was higher.When the water-material ratio was 0.5,the sugar concentration and osmotic pressure of fermenting mash were higher.When...
