摘要
酯类是白酒中的主要香气成分,本文主要介绍西南菌种站保存的部分酿酒增香酵母在不同发酵培养条件下的产酯能力。试验对7株产酯酵母进行3种培养基、3种培养时间的多配方处理发酵,采用皂化法测定总酯。实验结果表明,菌株SICC 2.644与SICC2.645产酯水平较高,分别达到230.2mg/100mL和171.2mg/100mL;大部分菌株于麦芽汁发酵培养能获得较为理想的产酯测试效果。
The main aroma components of Liquor are esters. Several yeasts which can produce aroma preserved by SICC were studied in this paper. The esters were measured. 3 kinds of medium were used. Results showed that SICC 2.644 and SICC 2.645 can reach high production levels. And most strains in the wort can be an ideal fermentation esters production test results.
