摘要: 大槽车体积为2 m3,小槽车体积为1 m3,经实验研究和生产实践表明,发酵结束时,小槽车中乙酸乙酯含量约为大槽车的1.5倍,乙乳比为最佳,约2.0,甲醇、正丙醇、异丁醇、异戊醇、杂醇油含量与大槽车持平,通过将整体为2 m3的大槽车改造成两个体积均为1 m3的小槽车,可以提高清香型小曲原酒主体香乙酸乙酯含量,使原酒香味更协调,提高原酒品质。关键词: 小曲酒新工艺; 槽车; 清香型; 乙酸乙酯

Abstract: The volume of the large fermentation tanker was 2 m³ and the volume of the small fermentation tanker was 1 m³. Experimental study and production practice demonstrated that, at the end of the fermentation, ethyl acetate content in the small fermentation tanker was about 1.5 times of that in the large fermentation tanker, and the ratio of ethyl acetate to ethyl lactate was about 2.0. The content of methanol, n- propyl alcohol, isobutyl alcohol, isoamyl alcohol and fusel oil in the small tanker was almost the same as that in the large tanker. Accordingly, reconstructing the 2 m³ large tanker into two 1 m³ small tankers could increase ethyl acetate content in Xiaoqu base liquor and improve the quality of Xiaoqu base liquor. Key words: new technology for Xiaoqu Baijiu; fermentation tanker; Qingxiang Baijiu; ethyl acetate

小曲酒是中国白酒的主要酒种之一,年产量约占

[1]白酒总产量的三分之一 。其生产多以高粱为原料,以根霉曲为糖化发酵剂,经过润料蒸煮、摊晾下曲、糖

[ 3]化培菌、粮糟混合、入池发酵、固态蒸馏而成2- 。

清香型小曲酒的香味组分以酯类和醇类为主,其次是有机酸类和羰基化合物,酯类总含量低于醇类总含量,酯类以乙酸乙酯为主,乳酸乙酯次之,乙酸乙酯与乳酸乙酯的比例为1∶1.0~0.6,风味特征是以乙酸乙酯为主体的协调复合香气,清香纯正,

[4]入口微甜,香味悠长,落口干爽,微有苦味 。但目 前对于清香型小曲白酒的研究甚少,对于白酒的香气成分的研究也主要集中于对香型成型后的白酒和对原酒的研究,或者是对丢糟中的微量成分的研究。目前鲜有文献或资料报道对整个酿造过程中酒醅的风味物质进行系统研究以探索白酒风味形成规律[ 5],尤其是对机械化酿造过程酒醅中风味物质的系统研究,国内尚属空白,因此研究白酒酒醅中的香气物质,对提升优质白酒质量评价系统及酿酒工艺具有理论与实践意义。
