功能性大豆分离蛋白的制备

Preparation of Functional Soybean Protein Isolate

大豆分离蛋白是一种高纯度的大豆蛋白制品，蛋白质含量在９０％以上。目前，国内外生产大豆分离蛋白主要以碱溶酸沉法为主。它可以控制和改变工艺流程中的温度、ｐＨ酸碱种类，前期处理和后期调整等手段生产功能特性各异的大豆分离蛋白。实验表明：采用不同的工艺参数、步骤和水解技术可以生产不同功能的大豆分离蛋白。

oybean Protein isolate(SPI) is a kind of high purity soybean protein product.Its protein content is more than90%.At present,it is produced in domestic and abroad mainly by alkalidi solution and acid sedimention.This method can produce various functionalS PI by controling temperature,pH,types of aikaliand acid,and by diferent pretreating and post ad justment.TheresultsshowedabrightfutureforSPIproduction.
