低场核磁共振技术在烟草中的应用研究现状

Research Status of Low Field Nuclear Magnetic Resonanc Technology in Tobacco

低场核磁共振技术因具有快速、精确、安全的特点,已应用于烟草领域的水分检测分析。采用低场核磁共振技术分析烟草的水分含量、水分赋存状态、水分迁移的机理和影响因素,对烟草的加工过程和质量分析控制等具有重要意义。对低场核磁共振技术的原理及其在烟草水分含量检测、水分赋存状态识别和水分迁移方向3个方面的应用进行了阐述,可为进一步推动低场核磁共振技术在烟草领域的研究和应用提供理论支持。

Low field nuclear magnetic resonance(LF-NMR)technology has been applied to the detection and analysis of moisture in tobacco fields because of its quick,accurate and safe characteristics.The LF-NMR technology was used to analyze the moisture content,water occurrence status,and mechanism of moisture migration in tobacco,which had important significance for the processing and quality control of tobacco.The principle of LF-NMR and its application in three aspects of tobacco moisture content detection,water occurrence status recognition and water migration direction were expounded,providing theoretical support for further promoting the research and application of LF-NMR technology in tobacco field.
