利用HPLC法进行胭脂红含量的检测

食品色泽是构成食品感官质量的一个重要因素。如何保持或赋予食品良好的色泽,一直是食品领域研究的一个热点问题。系统研究了食用合成色素胭脂红含量的测定方法,并对目前市场上常见的四大类16种食品的胭脂红含量进行了测定。研究表明,采用HPLC法,测定食品的合成色素含量是一种精密度和准确度都较高的检测方法,为食用合成色素的检测提供了有效的途径。目前市场上常见的食品中,仍有违规使用或者超过使用人工色素的现象,提醒消费者在选购食品时,一定要注意食品安全卫生。

Study on Detection of Carmine by High-Performance Liquid Chromatography

Food color was important factor of sensory index.So keeping color of food was important problem in the food field.In this paper,the detection methods of the carmine contents were studied.The carmine content in the 16th species of food in the market were detected.The results showed that high-performance liquid chromatography was precision and accuracy method and provided effective ways of detection of synthetic pigments.Meanwhile,the results showed that there were still some artificial synthetic pigments in the current food,so the food sanitations were paid more attention.
