动植物油脂.高效液相色谱法测定维生素E和三烯甘油酯含量

[中文适用范围]： 本国际标准规定了一种方法，用于测定动植物脂肪和油（以下简称油脂）中游离α-、β-、γ-和δ-托可色烯醇类化合物（统称为托可色烯醇，简称为"tocols"）的含量。对于含有托可色烯醇酯的产品，需要先进行皂化处理。本国际标准不适用于牛奶及乳制品（或来自牛奶及乳制品的油脂）。 [外文原描述]： ISO 9936:2016 specifies a method for the determination of the contents of free α-, β-, γ-, and δ-tocopherols and tocotrienols (referred to jointly as tocols) in animal and vegetable fats and oils (referred to hereinafter as fats) by high-performance liquid chromatography (HPLC). For products containing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification. Milk and milk products (or fat coming from milk and milk products) are excluded from the Scope of this International Standard. NOTE A suitable method involving a cold saponification procedure is described in Annex B for information only.
