光谱技术在肉品掺杂掺假鉴别中的应用研究进展

Application of Spectroscopic Techniques in Identi?cation of Meat Adulteration: A Review

近年来,肉品安全事件频发,掺杂掺假现象屡见不鲜,甚至成为市场潜规则,这严重威胁到消费者身心健康,扰乱了我国肉类工业的健康、可持续发展。建立快速、无损的检测技术有利于从技术层面保障肉品真实性,从而保障肉品市场的健康发展。传统检测技术,如通过DNA(酶联免疫吸附测定和聚合酶链式反应)、蛋白质、脂肪鉴别的方法,存在有损、耗时长和操作复杂等缺点。光谱技术,如近红外光谱、高光谱成像、拉曼光谱等,作为快速、无损检测技术在肉品掺杂掺假鉴别方面有很好的应用前景。本文综述近红外光谱、高光谱成像和拉曼光谱技术在肉品掺杂掺假的定性判别和定量检测中的研究进展,并分析了3种光谱技术的应用现状及存在的问题,并对其应用前景进行了展望。

In recent years, meat safety incidents have occurred frequently. Meat adulteration has been a common occurance,which not only poses a threat to consumer health, but also restricts the sustainable development of China’s meat industry.Establishment of rapid and non-destructive detection techniques can provide technical support for identifying the authenticity of meat products and thus ensuring healthy development of the meat market. Traditional detection techniques for DNA(enzyme linked immunosorbent assay and polymerase chain reaction), protein and fat are destructive, time consuming and complicated to operate. By contrast, spectroscopic techniques, such as near-infrared spectroscopy, hyperspectral imaging and Raman spectroscopy, enable fast, non-destructive and online detection and hold great promise for application in the identification of meat adulteration. In this paper, recent progresses in the application of near-infrared spectroscopy,hyperspectral imaging and Raman spectroscopy in the identification and quantification of adulterated meat are reviewed, and existing problems and future prospects are discussed.
