Abstract:
In order to separate and purify the soybean trypsin inhibitors, immobilized trypsin was prepared by coupling siliconechitosan activated carriers with trypsin using glutaraldehyde as coupling agents. The influence factors of coupling reaction including glutaraldehyde concentration, reaction temperature and trypsin concentration were investigated and the results showed that the best conditions were as follow: the concentration of glutaraldehyde was 2.0%, the temperature was 20℃, and the ratio of trypsin with silicone-chitosan was 15∶1 000. The activity of soybean trypsin inhibitors isolated by the above immobilized trypsin was 1872.51 U?mg-1, and the purified degree increased 46.22 times. The results suggested that soybean trypsin inhibitors with higher activity can be obtained by this method and it is a better way to exploit the soybean trypsin inhibitors.
