低场核磁共振技术在肉类品质安全分析检测中的应用

随着人们对肉类产品需求的逐渐增加, 肉类的品质安全问题也成为全民日益关注的焦点。近年来, 肉类掺假现象十分严重, 不仅扰乱市场秩序, 而且危害消费者的身体健康。传统检测方法已无法对肉类品质安全问题作出快速准确的鉴别。而低场核磁共振技术(low-field nuclear magnetic resonance, LF-NMR)因具有快速、无损、样品需要量少等优势, 将在未来肉类品质安全检测中得到越来越广泛的应用。本文介绍了低场核磁共振技术基本原理, 并从肉类营养组分、食用品质以及掺杂掺假方面, 综述了其在肉类科学领域的应用现状, 重点总结分析了低场核磁共振技术在掺杂掺假方面的应用研究进展, 以期为该技术的进一步发展奠定理论基础, 同时展望其未来在肉类食品检测中的应用前景。

Application of low field nuclear magnetic resonance technology in the quality and safety analysis and detection of meat

With the increasing demand for meat products, the quality and safety of meat has become the focus of increasing attention of the whole people. In recent years, the phenomenon of adulteration of meat is very serious, which not only disturbs the market order, but also endangers the health of consumers. Traditional detection methods have failed to quickly and accurately identify meat quality safety issues. Low-field nuclear magnetic resonance (LF-NMR) will be widely used in future meat quality safety testing due to its advantages of fast, non-destructive, and low sample requirements. This paper introduced the basic principles of low field nuclear magnetic resonance technology, and reviewed the application status of meat nutrition components, food quality and doping adulteration in the field of meat science, and summarized the research progress of low field nuclear magnetic resonance technology in doping adulteration, in order to lay a theoretical foundation for the further development of this technology, and look forward to its future application prospects in meat food testing.
