中文摘要:

      合成色素作为添加剂被广泛应用于食品中, 但是合成色素的超范围添加和非法添加会给人体健康带来安全隐患, 有必要对其含量进行检测。由于食品基质较为复杂, 一般在进行分析检测前需要通过前处理进行样品的提取富集。本文主要对色素的传统富集方法包括液-液萃取和萃取柱萃取等研究进展进行介绍, 并重点综述了新型材料在富集色素方面的应用, 主要包括二维材料、有机金属框架及磁性复合材料, 为合成色素检测前处理阶段吸附剂的选择提供了系统性知识, 同时对未来合成色素吸附剂的发展进行展望。

英文摘要:

      Synthetic pigments are widely used in foods as additives, but the over-range addition and illegal addition of synthetic pigments will bring potential safety risks to human health, so it is necessary to detect their content. Because of the complexity of food matrix, it is generally necessary to extract and enrich the samples through pretreatment before analysis and detection. This paper mainly introduced the research progress of the traditional enrichment methods of pigment, including liquid-liquid extraction and extraction column extraction, reviewed the applications of new materials in pigment enrichment including two-dimensional materials, organic metal frames and magnetic composites, so as to provide the systematic knowledge for the selection of adsorbents in the pre-treatment stage of synthetic pigment detection, and forecast the development of synthetic pigment adsorbents in the future.
