油料产品产地溯源技术研究进展

Research Progress on Geographical Origin Traceability of Oil Products

油料产品可为人们提供必需脂肪酸和丰富的脂溶性营养成分,是居民膳食中不可或缺的一部分。然而,油料产品产地造假现象时有发生,损害消费者权益,威胁消费者身体健康,亟需建立有效的油料产品产地溯源技术。本文综述了油料产品产地溯源技术包括矿物元素指纹谱与稳定同位素比率法、光谱法、代谢指纹谱法以及DNA分子标记法等,介绍了几种溯源技术的原理和应用现状,分析了各种方法的优缺点,并对油料产品产地溯源技术应用前景进行展望,以期为油料产品产地溯源技术的进一步发展提供参考。

Oil products provide essential fatty acids and fat soluble nutrients,which are an integral part of the human diet.However,adulteration of oil origin occurs from time to time,which damages the quality and safety of oil products,as well as the rights and interests of consumers products.Therefore,it is urgent to establish effective detection methods for geographical origin traceability of oil.In this review,the techniques of geographical origin traceability of oil products,including mineral element fingerprinting,stable isotope ratio analysis,spectroscopy,metabolic fingerprinting and DNA marker-based methods were summarized and analyzed,as well as the principle and application status of several traceability techniques.Moreover,the advantages and disadvantages of these technologies were prospected.More importantly,the applications of geographical origin traceability technologies of oil and products were prospected in order to provide a reference for the further development of the geographical origin traceability methods for oil products.
