中文摘要:

      食用油脂既是人们膳食结构中不可缺少的重要组成部分, 也是食品工业的重要基础原料, 其品质和安全性对人类健康有着重要的影响。当前食用油市场较为混乱, 各种掺伪现象层出不穷, 其掺伪种类和方式多变且复杂, 使得油脂掺伪检验已成为油脂安全监控领域的一项技术性难题, 亟待建立一套科学、有效的食用油脂掺伪鉴别方法以保护消费者健康, 保障食品安全, 强化政府监管能力。本文重点综述了气相色谱、液相色谱和色质联用等色谱技术, 红外光谱、近红外光谱和拉曼光谱等光谱技术, 以及核磁共振法和电子鼻技术等现代分析技术在食用油脂掺伪鉴别中的最新研究进展和应用中存在的问题, 并展望今后研究方向, 旨在为食用油掺伪鉴别研究提供一定的思路和方法指导。

英文摘要:

      As an important part of people's diet structure, as well as the important basic raw material of food industry, the quality and safety of edible oil have an important influence on people’s health. Now the edible oil market is quite disordered, with diverse and complex adulteration phenomenon emerging frequently, which made oil adulteration become a technical problem in the field of oil security monitoring. Therefore, a set of scientific and effective methods for edible oil adulteration identification need to be established, to protect consumers’ health, to ensure food safety, and to strengthen the supervision power of government. This paper mainly reviewed the latest research progress and existing problems of modern analytic technologies including gas or liquid chromatography, infrared/near infrared spectrum, raman spectrum spectroscopy, nuclear magnetic resonance method as well as electronic nose technology for edible oil adulteration detection, as well as to prospect the future research, aiming at supplying a detailed way for edible oil adulteration identification.
