Three kinds of high-molecular polysaccharides: alginate, chitosan and carrageenan, were tested as carriers for the immobilisation of proteolytic enzymes. The catalytic system consisted of the endopeptidase - chymotrypsin and exopeptidases: carboxypeptidase A and leucine aminopeptidase. Subsequently, this immobilised system was used for making of enzymatic hydrolysates of casein. In the case of periodic method of casein hydrolysis the best results (71.9% of tyrosine and tryptophan released) were achieved after 72 h, at substrate concentration 0.5% and with alginate as a carrier. In the semi-continuous method chitosan appeared to be the best carrier and after 72 h the degree of hydrolysis was 48.6% (52.7% of tyrosine and tryptophan released) at the concentration of casein 2%.
