标准摘要
[中文适用范围]: 本文件规定了植物油和油脂中甘油二酯绝对含量及异构化程度的测定方法。在储存过程中或因酸催化反应,1,2-甘油二酯会转化为更稳定的1,3-异构体。注:本文件所得结果未与ISO 29822标准所得结果进行比较。 [外文原描述]: This document specifies the determination of the absolute value of diacylglycerols as well as the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalysed reaction. NOTE Results obtained using this document have not been compared with results obtained using ISO 29822.
英文名称Vegetable fats and oils — Determination of the content and relative amounts of 1,2- and 1,3-diacylglycerols — Part 2: Isolation by solid phase extraction (SPE)
