食品中脂肪测定国家标准的分析与探讨

食品中脂肪的测定是食品营养成分检测的重要环节,是人们健康饮食的重要保障。国家卫计委于2016年12月23日发布了GB 5009.6-2016《食品安全国家标准食品中脂肪的测定》,替代了9个关于食品中脂肪测定的标准,是国家强制实施的统一的、普适性的脂肪检测标准。但由于食品种类繁多,脂肪形态性状各异,脂肪检测方法原理多样等原因,普适性标准可能存在一些不具体、不适用情况。本文通过比较被替代标准及脂肪检测文献的脂肪检测原理、适用范围及流程,综述了食品中脂肪测定国家标准的制样、取样、萃取、恒重技术控制关键点。

Determination of fat in food is an important part of food nutrition detection, and is an important guarantee for people's healthy diet.On December 23, 2016, the National Health Planning Commission issued the GB 5009.6-2016 "the determination of fat in food safety national standard food", which replaced 9 standards for the determination of fat in food.It is a unified and universal standard of fat testing compulsory by the state.However, because of the variety of food, the fat morphological characters are different, the principle of fat detection method is diverse, the universal standard may exist some unspecific and unsuitable conditions.In this paper, by comparing the principle, scope and process of fat detection in the literature of substitutes and fat testing, the key points of controlling the sample, sampling, extraction and constant weight technology of the national standard for the determination of fat in food were summarized.
