中文摘要:

      动物油脂是动物脂肪组织经提取精炼而成的油脂。动物油脂因资源丰富, 具有独特风味, 广泛应用于制备食用动物油、起酥油、肉味香精, 同时也是生产肥皂、甘油和饲料的重要原料。然而, 因动物油脂价格低, 不法商贩受利益驱使在食用植物油或高价动物油脂中掺加低价动物油脂, 严重扰乱了市场秩序, 侵害消费者合法权益和身体健康。近年来, 气相色谱法与液相色谱法及其质谱联用技术、实时分析质谱法、近红外光谱法与拉曼光谱法等光谱法、低场核磁共振等技术应用于食用油掺假鉴别技术研究。本文对主要食用油掺假鉴别技术进行综述, 并对其发展趋势进行了展望, 以期为食用油中掺入低价动物油脂的鉴别技术发展提供参考。

英文摘要:

      Animal fat is a kind of oil extracted and refined from animal tissue. Because of its rich resources and unique flavor, animal oils are widely used in the preparation of edible animal oil, shortening and meat flavor, and are also important raw materials for the production of soap, glycerin and feed. Due to the low price of animal oil, driven by interests, illegal traders add low-priced animal oil to edible vegetable oil or high-priced animal oil, which seriously disrupts the market order and infringes on the legitimate rights and interests of consumers and their health. In recent years, gas chromatography, liquid chromatography and mass spectrometry, real-time analytical mass spectrometry, near infrared spectroscopy, Raman spectroscopy and low field nuclear magnetic resonance have been applied to the identification of adulterated edible oil. This paper summarized the main identification techniques of adulteration of edible oil, and prospected its development trend, in order to provide reference for the development of identification techniques of low-priced animal oil mixed in edible oils.
