食用油掺伪鉴别技术及模型建立的研究进展

Research progress of edible oil adulteration identification technology and model establishment

随着食用油掺伪现象频繁出现,对食用油的质量控制显得尤为重要,建立有效的食用油掺伪鉴别体系是保证食用油品质的重要手段。由于食用油掺伪物质复杂多样,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仪器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技术、光谱分析技术及新型分析技术手段对食用油掺伪的检测,同时分析了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的原理及对模型的国内外应用进展进行了概述,在此基础上对目前食用油掺伪模型的建立方法提出展望,以期为食用油品质掺伪鉴别模型的建立提供理论参考。

With the frequent occurrence of edible oil adulteration,the quality control of edible oil is very important.The establishment of effective edible oil adulteration identification system is an important means to ensure the quality of edible oil.Due to the complexity and diversity of adulterated substances in edible oil,traditional physical and chemical detection has been unable to accurately analyze the complex adulterated components in edible oil.Therefore,it is necessary to establish a fast,accurate and efficient identification method of edible oil adulteration by using modern instrument analysis technology and related data metrology processing method.This paper reviewed the detection research progress of edible oil adulteration by chromatographic analysis technology,spectral analysis technology and new analytical technologies,and analyzed the principle of adulteration model based on the difference of edible oil composition and content by means of stoichiometry,and summarized the application progress of the model at home and abroad.On this basis,this paper prospected the present methods of edible oil adulteration model,in order to provide theoretical reference for the establishment of edible oil adulteration identification model.
