植物油脂.甲苯不溶物的测定

[中文适用范围]： 本文件规定了磷脂制剂中丁香树脂油含量测定的方法，表示杂质的存在，如蛋白质、含碳水化合物的提取残留物和其他固体污染物。该方法适用于各种植物磷脂。此方法的目的是在多项法规下进行分析。磷脂[国际食品添加剂编码系统（INS）编号 322]是通用允许添加剂，丁香树脂油含量测定是许多规范的一部分。关于丁香树脂油含量的规定基于本文件中规定的方法。甲苯用于代替致癌物苯，苯是以前方法中使用的溶剂。 [外文原描述]： This document specifies a method for the determination of the content of toluene insoluble matter (TIM) in lecithin formulations, which indicates the presence of impurities such as protein, carbohydrate-containing extraction residues and other solid contaminants. This method is applicable to all types of vegetable lecithin. The purpose of the method is to enable the analysis of lecithin under several regulations. Lecithin [Codex International Numbering System for Food Additives (INS) No. 322] is a generally permitted additive and the determination of the TIM is part of many specifications. The purity requirement with regard to TIM content is based on the method specified. Toluene is the replacement for the carcinogenic benzene, which was used in older methods.
