摘要：

A new ion-exclusion HPLC procedure for the determination of organic acids in vinegars under isocratic elution was developed. Optimum experimental conditions for pH of the eluent, column temperature and mobile phase flow-rate were estimated from a factorial design. The method was successfully validated and enables the reliable separation of major organic acids in wine vinegars (i.e. tartaric, citric, malic, lactic and acetic acid) in about 25 min. It was applied to the analysis of different vinegar samples. (C) 1998 Elsevier Science B.V. All rights reserved.
