| Abstract: | The rana skin was used as a raw material.Alkali protease were chosen and the influences of the five process parameters which were enzyme solution temperature,enzymatic hydrolysis time,plus enzyme quantity,pH and liquid materials were studied.According to the experiment,the optimal media conditions were 50℃ temperature zymolysing,adding enzyme quantity 0.5%,zymolysing time 3h,pH9.0,1∶3 liquid to material rate(g/mL).After decoloring and deodorization processing,yellowish powder rana skin collagen peptide was got through spray drying.The results showed that hydroxyproline content was 20.69μg/mL and molecular weight was under 3.5ku. |
