六十年代以来,国内外在研究提高水稻产量的同时,也注意到稻米品质的问题.稻谷和糙米中蛋白质的含量,对稻米的营养价值影响甚大,是稻米品质的一个重要内容和指标,也是当今水稻育种中急待研究的课题.稻米中含氨量测定法,除了传统的凯氏定氮法之外,尚有双缩脲显色法,等等.但是既快速而又非破坏性地分析稻米中的粗蛋白质含量的方法,在国内则未见报导,这正是高蛋白稻米品种选育中迫切要求解决的问题.我们应用14Mev快中子活化分析测定了广东省部分籼稻稻米品种的粗蛋白质含量,并与凯氏法作了比较.14Mev快中子活化分析的优点在于快速、非破坏性,它满足了高蛋白稻米品种选育中对大量样品分析的要求.活化分析测定谷物种子或大米中的粗蛋白
Since the 1960s, at home and abroad, while studying and improving the yield of rice, the quality of rice has also been noticed. The content of protein in rice and brown rice has a great influence on the nutritional value of rice, which is also an important content and indicator of the quality of rice In today’s rice breeding project urgently studied. Determination of ammonia content in rice, in addition to the traditional Kjeldahl method, there are biuret chromogenic method, etc. However, both fast and non-destructive The method of analyzing crude protein content in rice has not been reported in China, which is the urgent problem to be solved in the breeding of high protein rice varieties.We used 14Mev fast neutron activation analysis to determine the content of some indica rice varieties Crude protein content, and compared with the Kjeldahl method.14 Mev fast neutron activation analysis of the advantages of fast, non-destructive, it meets the high protein rice varieties for breeding a large number of sample analysis requirements. Activation analysis of cereal seeds Or crude protein in rice
