摘要: 有机酸是对啤酒质量(口感和稳定性)有重要影响的一类物质,本文通过采用HPLC法测定国内市售的20种啤酒中主要有机酸的含量,且采用统计学中多指标综合评价法,建立了以6种有机酸(丙酮酸、苹果酸、乳酸、乙酸、柠檬酸和琥珀酸)为指标综合评价啤酒的方法。通过该方法可以对啤酒或者试验样品进行整体性比较和“优劣”排序,对研究啤酒中有机酸类物质的组成有重要意义。

Abstract: Organic acids in beer play a very important role in beer quality. The compositions of organic acids in 20 domestic beers samples were determined by HPLC. A new method of comprehensive evaluation of the beer with the contents of organic acids was proposed by applying the statistic methodology. The differences of organic acid contents in a number of beer samples can be more conveniently found out by this method with important significance for further study on organic acids in beer.

Key words: organic acids, beer, comprehensive evaluation
