DEBITTERING CASEIN HYDROLYSATES WITH OCTADECYL-SILOXANE (C18) COLUMNS

Three casein hydrolysates (degree of hydrolysis (DH) of 23, 47, and 65 .5 (%)) were debittered using three different hydrophobic adsorption c olumns, C18, C8, and phenolic resin (PR). Higher DH hydrolysates resul ted in higher total nitrogen yields through the debittering process. T he C18 and PR columns had more effective debittering than the C8 colum n, which had the highest processing yield. The PR column had much lowe r processing yield than the C18 column. Q-value correlated with bitter ness in the hydrolysates. Antigenicity of treated hydrolysates was red uced by the debittering process.
