| Abstract: | In this study, alcalase was used for producing CPPs by hydrolyzing low-grade casein. The optimum conditions: casein concentration 15%,enzyme usage 800u /g substrate, temperature 55 ,pH 9.0 and time 2.5 hours were determined. The N /P ratio and the yield of CPPs were 4.371 and 12.88% respectively. |
