标准范围

本文件规定了测定卵磷脂配方中甲苯不溶物（TIM）含量的方法，该方法表明存在杂质，如蛋白质、含碳水化合物的萃取残留物和其他固体污染物。该方法适用于所有类型的植物卵磷脂。该方法的目的是使卵磷脂的分析符合若干规定。卵磷脂[Codex国际食品添加剂编号系统（INS）第322号]是一种普遍允许的添加剂，TIM的测定是许多规范的一部分。TIM含量的纯度要求基于规定的方法。甲苯是致癌物苯的替代品，而致癌物苯曾在旧方法中使用。

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.
