有机酸是影响食品风味的重要因素,水果、黄酒等农产品或农副产品中各种有机酸的含量和组成比例影响着它们的品质。目前,一般只采用简单的总酸测定来评价其品质。采用液相色谱技术可对样品中含有的草酸、苹果酸、酒石酸、乳酸、醋酸、柠檬酸、琥珀酸等各有机酸进行定量。 Organic acids are important factors that affect the flavor of food. The content and composition ratio of various organic acids in agricultural products and agricultural products, such as fruits and rice wine, affect their quality. At present, generally only a simple total acid measurement to evaluate its quality. Liquid chromatography can be used to quantify organic acids such as oxalic acid, malic acid, tartaric acid, lactic acid, acetic acid, citric acid and succinic acid contained in the sample.
