THE ATTEMPTS TO INTENSIFY SYNTHESIS OF GALACTOOLIGOSACCHARIDES IN THE PROCESS OF ENZYMATIC LACTOSE HYDROLYSIS - SHORT REPORT.

Transgalactosylation properties of the commercial preparations of beta-galactosidase: Lactase and Maxilact and of the preparation synthetized by Penicillium canescens, were compared. The effect of 2% glucose addition to 20% milk permeate solution on the process of formation of galactooligosaccharides during the enzymatic bioconversion of lactose by the examined beta-galactosidase preparations, was also studied. It was found that enzymatic synthesis of galactooligosaccharides in the process of lactose bioconversion was greatly dependent on beta-galactosidase used and that the presence of glucose in lactose solution already at the beginning of hydrolysis was favourable for the formation of oligosaccharides.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.
