摘　　要：针对酒精发酵原料中的半纤维素、植酸和发酵过程中酵母产生的海藻糖,山东隆科特酶制剂有限公司推出了超耐热植酸酶、超耐热木聚糖酶、海藻糖酶三款酶制剂。对这三款产品的性质及其在酒精生产中的应用方法和效果作了介绍。超耐热植酸酶在液化工序添加,能够水解植酸,释放出玉米原料中的肌醇、无机磷、金属离子等,有利于:淀粉、蛋白的分离和酶解、促进酵母的生长代谢、提高出酒率、缩短发酵周期、提高DDGS的营养价值。针对小麦原料的酒精生产中工艺中,超耐热木聚糖酶能够显著降低液化醪粘度、改善液化效果、提高小麦掺混比例、减少发酵泡沫、提高出酒率、缩短发酵周期。在酒精发酵过程中添加海藻糖酶可以将发酵过程中产生的海藻糖水解为葡萄糖,供酵母利用,提高出酒率。Taking aim at hemicellulose and phytic acid in raw materials and trehalose produced by yeast during fermentation process in alcohol fermentation, Shandong Lonct Enzymes Co., Ltd has launched three enzyme preparations, super thermostable phytase, super thermostable xylanase and trehalase. The properties of these three products and their application methods and effects in alcohol production were described in this paper. Super thermostable phytase could hydrolyze phytic acid and release inositol, inorganic phosphorus, metal ions,etc. in corn material., when it was added in the liquefaction process, which was beneficial to the separation and enzymatic degradation of starch and protein, promoting the growth and metabolism of yeast, elevating the yield of alcohol, shortening the fermentation period, and improving the nutritional value of DDGS. In the alcohol production process using wheat as raw material, super thermostable xylanase could significantly reduce the viscosity of liquefied mash, improve the liquefaction effect, increase the ratio of wheat in the mixture of raw materials,reduce fermentation foam, increase the yield of alcohol, and shorten the fermentation period. The trehalase supplemented in the alcohol fermentation process, could hydrolyze the trehalose produced in the fermentation process into glucose, which would be used by yeast to improve the alcohol yield.
