the preparation of gelatin hydrolyzed with as1. 398 neutral protease at different temperatures. the hydrolysis degree was tested by means of formaldehyde titration.
在不同的温度下,用as1.398中性蛋白酶制备水解明胶,甲醛滴定法测定明胶的水解程度。
the predict hydrolysis degree was 11.28% under these conditions and the test hydrolysis degree was 11.24%.
在此条件下水解度的预测值为11.28%,实际测定的水解度值为11.24%。
in this paper, fdnb method, uv-spectrophotometry, formaldehyde reaction-titration method and viscometry were tried to use in measuring the gelatin hydrolysis degree in the process of the reaction.
under these conditions the hydrolysis degree could reach 31.1%.
在此最佳条件下,蛋白质的水解度可达31.1%。
a great amount of simple salt could weaken the effect of hpam. when the hydrolysis degree of hpam became higher, more simple salt was needed to screen the effect of hpam thoroughly.
