摘要:

食用植物油保真检测技术是食用植物油打假和保证人民身体健康的重要手段。三酰甘油酯是占食用植物油90%以上的主要成分,但是我国目前的检测技术仅能检测三酰甘油酯酰基链结构,即通过甲酯化方式检测脂肪酸含量,该方法不能真实反映三酰甘油酯的结构和含量。本文综述国内外最新的三酰甘油酯分析技术和化学计量学分析三酰甘油酯指纹谱的食用植物油保真检测技术研究进展,为保障我国食用植物油安全消费提供重要的技术支撑。

Abstract:

The detection technologies for authentication of edible vegetable oils provide an important means for crackdown
against fake or adulterated vegetable oils and consequently ensuring people’s health. Triacylglycerols (TAGs) are the main
components of vegetable oils, accounting for more than 90% of the total oil composition. Nowadays, the methods used
for TAGs detection are mainly based on the evaluation of their acyl chain structure, during which the methyl esterification
of fatty acids is performed. However, such methods do not provide information about the precise structures and contents
of TAGs. This article has reviewed the latest studies that have been conducted to develop detection technologies for
authenticating edible vegetable oils by TAGs determination and chemometrics analysis of TAGs fingerprints, aiming to
provide technical support for ensuring the safety of edible vegetable oils.

Key words: edible vegetable oil, triacylglycerols, chemometrics
