地沟油不同检测技术研究进展

Research Progress on Different Inspections of Drainage Oils

地沟油是生活中各类劣质食用或非食用油脂的统称,长期食用会对人体造成严重危害。根据地沟油的理化性质对不同检测方法优劣势进行比较,介绍现有的检测技术原理及检测分析现状,通过对当前多种检测方法的综合比对,发现现有诸多方法并不能准确判定地沟油来源与种类,提出探究地沟油特征目标物并结合相关检测技术实现准确判定及快速检测,以期为地沟油的检测新方法研究提供参考,为建立地沟油评价新体系理清思路。

Drainage oils are a general designation of all kinds of inferior edible or inedible oils in daily life, long-term eating of them will cause serious harmful to human body. According to the physicochemical properties of drainage oils and compare the advantages and disadvantages of different inspection methods, this paper introduces the existing inspection technologies principle and their research progress, based on the current comprehensive comparison of inspection methods, find that these methods can＇t accurate determining the sources and types of drainage oils. We need to combine with the features related inspection technologies to exploring the special marks of drainage oils so that may realize accurate evaluation and instant inspection. All of these expect to provide concrete references for founding new methods of testing drainage oils and clarifying the thought of setting up a new evaluation system of drainage oil.
