食用油掺伪鉴别技术及模型建立的研究进展

随着食用油掺伪频繁出现,掺伪物质复杂多样,基于传统的理化检测已无法准确实现食用油复杂掺假组分的分析。因此有必要利用现代分析技术手段结合相关数据计量学处理方法建立快速、精准、高效的食用油掺伪鉴别方法。本文综述了色谱分析、光谱分析及新型分析技术手段对食用油掺伪的检测,对借助化学计量学方法基于食用油组成成分种类及含量差异性而建立的掺伪模型原理及模型的应用进展进行了概述,并对目前食用油掺伪模型的建立方法提出展望,以期为食用油掺伪鉴别模型的建立提供理论参考。

Research progress of edible oil adulteration identification technology and model establishment

With the frequent occurrence of adulterated edible oil, adulterated substances are complex and diverse, so the analysis of complex adulterated edible oil components based on traditional physical and chemical detection can not be accurately realized. Therefore, it is necessary to establish a fast, accurate and efficient identification method of edible oil adulteration by using modern analytical techniques combined with relevant data metrology processing methods. In this paper, the detection of adulteration of edible oil by chromatography, spectroscopic analysis and new analytical techniques was reviewed, and the principle and application progress of the adulteration model established by chemometric methods based on the difference of the composition and content of edible oil were outlined. An overview and the prospect of the establishment of the current edible oil adulteration model was put forward in order to provide a theoretical reference for the establishment of the edible oil adulteration identification model.
