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
