本文件规定了使用气体测定乳脂纯度的参考方法 甘油三酯的色谱分析。该方法利用了甘油三酯的差异 乳脂的指纹图谱由单个甘油三酯的指纹图谱确定其他脂肪和油脂 超出通常观察到的乳脂范围的样品。这是通过使用 基于单个甘油三酯峰的标准化加权和定义的甘油三酯公式 对牛奶的完整性敏感[6][7]。乳脂的完整性可以通过将这些配方奶粉的结果与之前在一系列纯乳脂样品中观察到的结果进行比较来确定[12]。植物脂肪和动物脂肪（如牛脂和猪油）都可以检测到。 交叉引用:ISO 1211ISO 1740ISO 3696ISO 7328ISO 2450ISO 1736ISO 14156ISO 5725-2ISO 5725-1ISO 707ISO 835BS 410（所有部分）ISO 3310（所有部分）购买本文件时提供的所有当前修订版均包括在内。

This document specifies a reference method for the determination of milk fat purity using gas chromatographic analysis of triglycerides. The method utilizes the differences in triglyceride fingerprint of milk fat from the individual triglyceride fingerprints of other fats and oils to determine samples which are outside the range normally observed for milk fat. This is achieved by using the defined triglyceride formulae based on the normalized weighted sum of individual triglyceride peaks which are sensitive to the integrity of the milk[6][7]. The integrity of the milk fat can be determined by comparing the result of these formulae with those previously observed for a range of pure milk fat samples[12]. Both vegetable fats and animal fats such as beef tallow and lard can be detected.Cross References:ISO 1211ISO 1740ISO 3696ISO 7328ISO 2450ISO 1736ISO 14156ISO 5725-2ISO 5725-1ISO 707ISO 835BS 410 (all parts)ISO 3310 (all parts)All current amendments available at time of purchase are included with the purchase of this document.
