乙酸乙酯是白酒中一种重要的活性芳香酯类化合物，对白酒的风格和品质有重要影响。因此，研究其形成机理在白酒酿造过程中具有重要意义。对白酒酿造过程的系统研究和分析表明，白酒中的乙酸乙酯主要来源于生物合成途径。同时，产香酵母菌是生产乙酸乙酯的主要菌种。重点介绍了酯化酶之一的醇乙酰转移酶在酵母合成乙酸乙酯中的研究进展。同时对利用产香酵母中的醇乙酰转移酶合成乙酸乙酯的研究进行了展望。
Ethyl acetate is an important active aroma ester compound in Baijiu, and it has important impacts on the style and quality of Baijiu. Therefore, it is of great significance to study its formation mechanism in Baijiu brewing process. Systematic study and analysis of Baijiu brewing process showed that ethyl acetate in Baijiu mainly came from biosynthesis pathway. Meanwhile, aroma-producing yeasts are the main strains that produce ethyl acetate. Especially, the research progress of alcohol acetyl transferase, which is one of esterification enzyme, in the synthesis of ethyl acetate in yeast was discussed. Meanwhile, the research on the synthesis of ethyl acetate by alcohol acetyl transferase in aroma-producing yeasts was prospected.
