中文摘要:

      罗丹明B(rhodamine B, RhB)是三苯甲烷类碱性水溶性染料, 曾被用作食品添加剂, 后因其致癌性而被禁止用作食品着色剂。近年来罗丹明B作为苏丹红替代品, 被非法添加到多类型食品中, 引起了食品研究的重点关注。本文针对传统液液萃取(liquid-liquid extraction, LLE)到新型磁性分子印迹聚合物整体固相萃取(magnetic molecular imprinting polymer solid phase extraction, M-MIP-SPE)等10余种前处理技术进行综述; 介绍了液相色谱法(liquid chromatography, LC)、液相色谱串联质谱法(liquid chromatography-mass spectrometry, LC-MS)、分光光度法、电化学法和现场快检方法的新进展。对食品中罗丹明B分析技术新进展进行梳理, 比较不同检测方法的优缺点, 总结了食品中罗丹明B的检测技术进展和发展趋势。以期为相关检测和研究人员提供参考。

英文摘要:

      Rhodamine B (RhB) is a triphenylmethane-based alkaline water-soluble dye. It was once used as a food additive, and was banned from being used as a food colorant because of its carcinogenicity. In recent years, RhB has been illegally added into many types of food as a substitute for Sudan red, which has attracted the attention of food research. This paper reviewed more than 10 pre-treatment technologies, including traditional liquid-liquid extraction (LLE) and magnetic molecular imprinting polymer solid phase extraction (M-MIP-SPE), and introduced the new developments in liquid chromatography (LC), liquid chromatography-mass spectrometry (LC-MS), spectrophotometric, electrochemical and field rapid assay. This article also reviewed the new development of rhodamine B analysis technology in food, compared the advantages and disadvantages of different detection methods, and summarized the progress and development trend of rhodamine B detection technology in food, in order to provide reference for related detection and researchers.
