Description
  • Galacto-oligosaccharides (GOS) have many biological functions. They are produced from lactose by a glycosyl transfer of one or more D-galactosyl units onto the D-galactose moiety of lactose catalysed by β-­galactosidase. This reaction can proceed in batch or in continuous system. Membrane reactor with ultrafiltration ceramic membrane (150 kDa) were used and batch system as well. Lactose in phosphate buffer (555 mmol.L-1), recombined whey (547 mmol.L-1) and evaporated ultrafiltration permeate (888 mmol.L-1) were used as substrates. The used concentration of enzyme Maxilact LX 5000 was 2 g.L-1. The highest concentration of GOS in buffer was reached after 30 min of batch reaction and it was 50.0 mmol.L-1, for recombined whey it was 52.0 mmol.L-1 and for ultrafiltration permeate it was 81.5 mmol.L-1. For continuous process was obtained 29.7 mmol.L-1 of GOS for buffer and 42.0 mmol.L-1 for recombined whey and 53.4 mmol.L-1 of GOS for ultrafiltration permeate.
