Abstract

This study developed a rapid and easy analytical method for the simultaneous determination of nine synthetic colourants (SCs) in capsule dietary supplements. Sample pretreatment involved thermal treatment to dissolve gelatin, using the enzymes protease and amylase to prevent the gelation of gelatin and fat-soluble substances removal using petroleum ether. The method was linear (r² ≥0.999), with LOD of 0.009-0.029 μg/mL and LOQ of 0.42-1.40 μg/g. Recovery ranged from 90.9 to 108.9%. The relative expanded measurement uncertainty ranged from 4.1 to 6.3%. Allura Red AC (R40) and Brilliant Blue FCF (B1) were commonly detected in 20 of the 28 samples. Up to six SCs such as Tartrazine (Y4), Sunset yellow (Y5), Amaranth (R2), Erythrosine B (R3), R40 and B1 were detected in a single sample, ranging from 30.5 to 40.2 μg/g. Total content of SCs in various capsule supplements ranged from 0.3 to 73.7 μg/g.

韩国市场上的胶囊膳食补充剂中含有合成色素。

本研究建立了一种快速简便的同时测定胶囊膳食补充剂中9种合成着色剂(SCs)的分析方法。样品的前处理包括热处理使明胶溶解，用蛋白酶和淀粉酶防止明胶凝胶化，用石油醚去除脂溶性物质。方法线性关系良好(r2≥0.999)，LOD为0.009 ~ 0.029 μg/mL, LOQ为0.42 ~ 1.40 μg/g。回收率为90.9 ~ 108.9%。相对扩展测量不确定度范围为4.1 ~ 6.3%。在28个样品中，有20个样品中检测到诱人红AC (R40)和亮蓝FCF (B1)。单份样品中最多可检出酒石黄(Y4)、日落黄(Y5)、苋菜黄(R2)、红素B (R3)、R40和B1等6种sc，含量范围为30.5 ~ 40.2 μg/g。各种胶囊补充剂中SCs的总含量在0.3 ~ 73.7 μg/g之间。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
