油菜籽品质测定方法(近红外反射光谱法与传统化学方法)的比较

COMPARISON OF NIRS AND ROUTINE METHODS FOR DETERMINING QUALITY COMPONENTS IN SEED MEAL OF Brassica napus L.

比较了用近红外反射光谱 (NIRS)法直接测定与用传统的化学方法测定油菜籽中硫代葡萄糖苷 (简称硫苷 )、芥酸、蛋白质含量和含油率的效果。结果表明用近红外反射光谱法测定具有快速、简便、样品用量少、无药品污染 ,准确度。

For determining four quality components such as glucosinolates, erucic acid, protein content and oil percentage in seed of Brassica napusL., the NIRS method was compared with routine chemical method. The results showed that NIRS had the advantages of simplicity, quickness, few amount required,pollution free and accuracy, so it can replace the routine method.
