Abstract (en)
[origin: WO2017120678A1] Methods are disclosed for the enzymatic preparation of galactooligosaccharide (GOS) from lactose using two different microbial lactase enzymes to maximize the extent of transgalactosylation during the digestion of lactose. Methods are also disclosed for avoiding the turbidity of a solution comprising GOS and lactose as it is adjusted for incubation with a yeast neutral lactase.
