核磁共振技术无损快速评价食品水分的研究

STUDY ON QUICKLY AND NON-DESTRUCTIVE ESTIMATE THE MOISTURE CONTENT OF FOOD USING NMR

水分作为食品的重要组成部分,其在食品中的含量、分布和存在状态的差异对食品的品质和保藏性等有显著影响。因此,研究食品在保藏期间的水分分布,准确、快速地测量和控制食品的含水量具有重要的意义。NMR法是一种比较容易测定含水量的分析手段,并且相对于其他测量方法,它具有突出的优势。文章最后讨论了3种利用NMR技术测定食品含水量的技术。

Water is one of important compositions of food. Its content, distribution and states have distinct influence on food quality and storage. So, it is important that we study moisture distribution, rapidly and truly determine moisture content of food. NMR has predominance comparing with other methods of determining moisture content. At last, this paper reports three techniques of measuring water content of food using NMR.
