GB/T15688—2024/ISO663:2017

動植物油脂不溶性雜質含量的測定

1范圍

本文件描述了動植物油脂中不溶性雜質含量的測定方法。

本文件適用于動植物油脂。如果皂類（特別是鈣皂）或氧化脂肪酸不作為不溶性雜質含量進行計

算，采用不同的溶劑和操作方法，使不溶性雜質含量的測定符合相關要求。

本文件不適用于乳及乳制品（指從乳及乳制品中提煉的油脂）。

2規范性引用文件

下列文件中的內容通過文中的規范性引用而構成本文件必不可少的條款。其中，注日期的引用文

件，僅該日期對應的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用

于本文件。

ISO661動植物油脂試樣的制備（Animalandvegetablefatsandoils—Preparationoftest

sample）

注：GB/T15687—2008動植物油脂試樣的制備（ISO661：2003，IDT）

3術語和定義

下列術語和定義適用于本文件。

3.1

不溶性雜質含量insolubleimpuritiescontent

在本文件規定的條件下不溶于正己烷或石油醚的物質及外來雜質的量。

注1：含量用質量分數表示。

注2：這些雜質包括機械雜質、礦物質、碳水化合物、含氮化合物、各種樹脂、鈣皂、氧化脂肪酸、脂肪酸內酯和

（部分）堿皂、羥基脂肪酸及其甘油酯等。

4原理

用過量正己烷或石油醚溶解試樣，對所得溶液進行過濾。再用同樣的溶劑沖洗殘留物和濾紙，使其

在103℃下干燥至恒重。

5試劑

警示─應采用處理危險品的操作規則，遵循各種技術、組織及個人的安全措施。
