摘  要:
试验对米酒酿造的酒曲用量、糖化时间、酵母用量和发酵时间等工艺条件进行优化,通过GC/MS分析对香气成分影响。结果表明,酒曲用量0.8%,糖化温度28℃,酵母用量0.6‰,糖化时间24 h,加水比1 1,发酵温度28℃,发酵时间24 h时,得到米酒酒度为5.0%(V/V),消除米酒中苦涩味。在优化米酒、传统米酒中各检出香气成分50种、30种,检出的化合物中,醇和酯是两类主要的香气组分,其中酯的种类最多,共27种和24种;其次是醇,分别为5种、4种,这两种香气物质占总含量的64%、93%,构成米酒主体香气成分;酸类物质分别为2种、1种;烷烃类物质分别为16种、1种。

摘  要:
In order to improve the flavor of the rice wine and make the quality of different jobs stable.And then thesaccharification ferments content,fermentation time were studied through single factor experiments with the orthogonal design.A kind of rice wine with good feels and 5.0%(V/V) alcohol content was obtained under the following conditions: saccharification ferments content 0.8%,saccharification temperature 28 ℃,yeast doasage 0.6‰,saccharification time 24 h,rice/water ratio 1 1,fermentation temperature 28 ℃,fermentation time 24 h.And in the optimizing rice wine,traditional rice wine aroma compositions CPC detected 50,30 kinds,these compounds,alcohols and ester is two kinds of main aroma components,including esters,most species of 27,24;Followed by alcohol,total 5,4 kinds.These two kinds of aromatic matter,64%,93% of the total content they make up the subject of rice wine aroma compositions.Acid material altogether 2,1 kinds,Alkane kind material16,1 kinds.
