食品中着色剂的检测方法研究进展

Research progress on the detection method of food colorant

着色剂是食品添加剂中的一大类分支,在食品加工和生产中有着广泛的应用。由于食品的基质类型复杂多样,着色剂的种类也非常多、性质差异大,给分析检测工作带来挑战。本文对近年来的食品中着色剂的检测方法进行综述,包括样品前处理和分析检测技术,并根据应用方法和适用的食品基质及检测目标物进行分类总结,为进一步开展食品中着色剂的检测方法的研究工作提供参考。

Colorant is an important kind of food additives in order to make food more visually attractive to consumers. Detection of colorants is a challenge for analysts because there are various kinds of colorants and the huge differences among them which due to the large variety of food pigments and matrix. This work pro-vided an updated overview in recent years on the analysis and detection methods about synthetic colorants in many kinds of foods including sample preparation and analytical technology. We also summarized these detec-tion methods of various food colorants depended on variety of foodstuff. Finally, actual application and future directions was discussed. We hope it could be referred to in the further research.
