TRYPTIC HYDROLYSIS OF CASEINOMACROPEPTIDE IN MEMBRANE REACTOR - PREPARATION OF BIOACTIVE PEPTIDES

Tryptic hydrolysis of caseinomacropeptide (CMP: C-terminal part of k-Casein) was used as a model in membrane reactor to study continuous production and isolation of bioactive peptides from milk proteins. Compared to the batch reactor, productivity of the proposed continuous process was 3 times higher after 3.5 hours of hydrolysis, but only 50% of the substrate is converted at steady state of the system. As shown by reverse-phase HPLC analysis, a good selectivity of the ultrafiltration membrane to various products was also obtained.
