中文摘要:

      柠檬酸是食品中的一种添加剂。柠檬酸目前为止只在葡萄酒中的含量有严格的规定,其他的食品中没有明显的规定,但是柠檬酸过量有可能引起疾病这种说法在一些报道中已经多次提到,因此,在不同的食品中还是要控制好柠檬酸的含量。柠檬酸也是乌梅中的有效成分之一,本文以乌梅为例对柠檬酸的检测进行了分析。食品中柠檬酸的检测方法有很多种,例如离子色谱法、高效液相色谱法、电泳法、气相色谱法、分光光度法等。本文主要采用高效液相色谱法来检测乌梅中的柠檬酸.

英文摘要:

      Citric acid is a kind of additives in food.So far,only the citric acid content in wine has strict standard.But excessive citric acid may cause disease in some reports.Therefore,it is important to control the use of citric acid strictly.Citric acid is one of the effective components of ebony,which has a variety of detection methods,such as ion chromatography,high performance liquid chromatography,electrophoresis,gas chromatography,spectrophotometry and so on.In this paper,high performance liquid chromatography was used to detect the ebony of the citric acid.
