ICP － AES 法测定大豆及其产品腐竹中硼含量

摘要

The boron content in three different kinds of bean and their products yubas were determined by inductively coupled plasma - atomic emission spectrometry (ICP - AES)to research the migration of boron during the process of yubas and the relationship of boron content between different beans and yubas. The results showed that the boron contents were detected in all of the three kinds of beans, and the content was between 18 ~ 24 mg / kg. The boron contents in yubas were different because of the beans,but the mobilitys of boron were independent of the species of bean,were all between 60% ~ 67% .%为了研究腐竹生产过程中硼元素的迁移，通过ICP － AES对三种不同原料豆和对应生产的腐竹中硼含量进行检测，探索不同原料豆与腐竹中硼含量之间的关系。结果表明，三种豆中均含有一定量的硼，范围在18～24 mg ／ kg之间。腐竹中硼含量随原料豆不同而不同，但其迁移率与原料种类无关，都在60％～67％之间。
