肉制品掺假鉴别技术研究进展

肉制品在食品消费中占很大比例,近年来,肉制品掺假问题日益严重,肉制品掺假鉴别和溯源分析成为研究热点。传统的通过感官及形态的肉类鉴别方法已经不能满足肉类掺假鉴别的需要。随着现代分析仪器和生物技术的发展,多种蛋白质分析法、DNA分析法和无损检测方法日趋成熟。基于蛋白质的检测方法,如免疫分析法和色谱分析法均可定量检测,但不适用于加工肉制品。基于样品特征光谱的无损检测方法操作简单,检测时间短,具有独特的优势。基于DNA的检测方法,特别是荧光定量PCR方法具有检测灵敏度高,结果重复性好等优势,将成为未来肉类物种鉴别的发展方向,具有很好的应用前景。

Research progress of identification techniques for meat products adulteration

Meat products account for a large proportion of food consumption. In recent years, a growing problem of adulterated meat, quantitative detection of adulteration and meat traceability analysis become a hot topic. This paper summarizes the research progress of protein analysis, spectral analysis and DNA analysis methods in terms of meat products adulteration, the research status and development of these detection techniques are discussed.
