摘要
本文对有机酸转化为相应酯类的规律及产酸微生物与酯类形成的关系在实验室条件下进行了初步的探讨。认为酒醅中有机酸转化成相应酯时是呈竞争性关系;产酸微生物的存在是生成酯类物质的基础;乙酸乙酯主要由产酯酵母产生,与酒醅中乙酸的含量不呈直线关系。
The regular pattern in which the organic acid is esterified to correspondingester and the relation between acid producing microorganism and ester formation is initiallystudied in the laboratory in this paper. The results show that when the organic acid is esteri-fied to corresponding ester in the vinasse,the competition relation is revealed. The existehceof acid producing microorgaism is the basis of yielding ester. The ethyl acetate is mainlyprodticed by ester-forming yeast.The volume of the ethyl acetate and the acetic acid is notin straight line relation to each other.
