摘　　要：总酸与总酯是酒分析中的两个重要指标,对酒的生产及其品质有很大的影响。常规检测总酸的方法有直接滴定法、酸度计法等,而总酯则采用皂化中和法加以测定。由于二项指标分别测定,且均系手工操作,因而操作繁琐,误差较大。文章应用自动电位滴定法进行分析,测定了3类6种酒中总酸与总酯的含量,获得了较为满意的结果。Total acid and total alcohol ester is an important indicator of the two, the quality of the wine production and has a great influence. Conventional methods of determination of total acid titration method directly, pH meter and so on, while the total esters are used saponification were determined by neutralization. As two indicators were measured, and both manual systems and thus easy to operate, big error. In the paper, the analysis by automatic potentiometric titration to determine by potentiometric titration Category 3 of 6 total acid total ester alcohol, obtained satisfactory results.
