食用植物油掺伪鉴别技术研究进展

A review of the determination methods of edible vegetable oils adulteration

近年来,植物油掺伪问题频发,现有理化特性和感官特性检测已无法满足相关的检测需求。由于检测时间长、检测成本高,以及复杂的检测过程导致气相色谱法和高效液相色谱法等仪器分析方法的应用受限。近期,新型传感技术、新材料和数字信息技术、电子鼻技术、机器视觉技术、组学技术等的发展为快速准确鉴别植物油掺伪提供了技术支持。鉴于此,以食用植物油掺伪技术为对象,本文综述了近期国内外对植物油掺伪检测的重要研究进展,讨论了光谱检测技术、色谱检测技术、电子鼻检测技术、机器视觉技术、组学技术等分析方法的特点及发展现状,并对植物油掺伪鉴别技术的发展进行了展望,以期为植物油的掺伪检测提供一定的理论参考。

Vegetable oils adulterations are frequently reported in recent years.The physicochemical and sensory characteristics are not suitable for the determination.Gas chromatography and high performance liquid chromatography are sensitive to verify the components.However,the detection time and cost as well as the complex detection processes result in the limited applications.The novel sensing technology,new materials and digital information technology,electronic nose technology,machine vision technology,and omics technology support the development of the rapid and accurate identification of vegetable oils adulteration.This paper discussed the characteristics and recent progress of vegetable oil adulteration on the topic of the spectrum detection,chromatographic detection,the electronic nose detection,machine vision technology,as well as omics technology,and introduced the prospective of vegetable oil adulteration identification,providing the determination knowledge for vegetable oil adulteration.
