| 摘 要： | 以市售山西老陈醋为试验样品,对其不挥发酸和有机酸进行测定,并采用灰关联分析方法对山西老陈醋中的不挥发酸与乳酸、酒石酸、苹果酸、琥珀酸、柠檬酸、α-酮戊二酸共6种有机酸进行关联度分析.结果表明：其中乳酸、琥珀酸、α-酮戊二酸与不挥发酸的关联度高,因此初步确定乳酸、琥珀酸、α-酮戊二酸、苹果酸为山西老陈醋有机酸特征成分.

| Abstract: | The non-volatile acid and organic acid in commercial Shanxi aged vinegar were determined.The non-volatile acid and six kinds of organic acid of Shanxi aged vinegar,including lactic acid,tartaric acid,malic acid,succinic acid,citric acid and α-ketone glutaric acid were analyzed by grey relational analysis method.The results showed that the lactic acid,succinic acid,α-ketone glutaric acid were in high correlation with non-volatile acid.According to the results,the lactic acid,succinic acid,α-ketone glutaric acid,malic acid were preliminarily determined as organic acids characteristic components of the Shanxi aged vinegar. |
