Název v původním jazyce

Batch and continuous hydrolysis of ovine whey proteins

Popis výsledku v původním jazyce

The aim of this work was to compare batch and continuous hydrolysis of ovine whey proteins in a membrane reactor and to evaluate influence of thermocalcic precipitation before hydrolysis. Reconstituted dried ovine whey fromlump cheese production (a traditional Slovak cheese) was used as a substrate for hydrolysis by Promod 439L protease from Bacillus licheniformis. Initial substrate had 2% proteins andpH8.5. Hydrolysis was performed directly (i) or after a pre-treatment (ii) comprising thermocalcic precipitation at 50 C followed by microfiltration at 40 C, batch-wise or in a membrane ultrafiltration (UF) reactor equipped with 8 kDa ceramic membrane. Mean residence time of 60 min was maintained after batch pre-hydrolysis of the substrate in the first 60min period, during which the permeate was recirculated. During the subsequent UF, the reaction volumewas kept constant by a continuous feeding of the substrate. After the pre-treatment (ii), crude protein decreased by 25%. Degree of hydr
