低分辨核磁共振技术在食品品质分析中的应用

Application of Low-Field Nuclear Magnetic Resonance Technique in Food Quality Analysis

摘要食品的品质和安全问题越来越受人们关注，探索实际可行的食品无损检测与品质评估技术正在成为研究热点。低分辨（即低场）核磁共振检测技术是一种新型的食品无损检测技术，该技术具有快速、准确及不损坏食品的优点。本文综述国内外低分辨核磁共振技术在食品检测方面的技术应用，综述了核磁共振技术在食品水分分析检测、食品玻璃化转变、食品掺假鉴别和果蔬无损检测等方面的应用，并展望了该技术在未来食品工业中的应用前景。

With increasing problems of food quality, rapid and non-destructive detection technology has become the research hotspots. Low-Field Nuclear Magnetic Resonance （LF-NMR） is a new non-destructive testing technology which has advantages of fastness, accuracy and intactness. In this paper, the technology of LF-NMR applying in food detection at home and abroad is summarized. And its applications are mainly discussed here including elaborating on the moisture testing and glass transition, identification in food safety and intact detection of fruit quality. Additionally, future directions in the development of LF-NMR for food industry are also discussed.
