GB/T15688—2024/ISO663:2017

動植物油脂不溶性雜質(zhì)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(zhì)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(zhì)含量進行計

算，采用不同的溶劑和操作方法，使不溶性雜質(zhì)含量的測定符合相關(guān)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(guī)范性引用文件

下列文件中的內(nèi)容通過文中的規(guī)范性引用而構(gòu)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(yīng)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。

sample）

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

3術(shù)語和定義

下列術(shù)語和定義適用于本文件。

3.1

不溶性雜質(zhì)含量insolubleimpuritiescontent

在本文件規(guī)定的條件下不溶于正己烷或石油醚的物質(zhì)及外來雜質(zhì)的量。

注1：含量用質(zhì)量分數(shù)表示。

注2：這些雜質(zhì)包括機械雜質(zhì)、礦物質(zhì)、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(nèi)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(yīng)采用處理危險品的操作規(guī)則，遵循各種技術(shù)、組織及個人的安全措施。
