Abstract: Galactooligosaccharides characterized by a high lactulose content and a process for their production are proposed.

Abstract: Proposed is an animal feed additive comprising or consisting of: (a) glucose; (b) galactose; (c) lactose; (d) minerals derived from milk, preferably from cow's milk; (c) proteins derived from milk, preferably from cow's milk; (f) organic acids; and (g) water, where component (c) is optional.

Abstract: Suggested is method for producing galactooligosaccharides, comprising the following steps: (i) Providing an aqueous milk sugar solution; (ii) Sterilising the milk sugar solution; (iii) Performing a transgalactosilation of the milk sugars present in the sterilised milk sugar solution of step (ii) by adding at least one beta-galactosidase within its optimum temperature and pH value intervals for a period of at least 30 minutes, obtaining a reaction mixture; (iv) Inhibiting the enzyme mass in the reaction mixture of step (iii), and (v) Confectioning the reaction mixture of step (iv), Wherein (a) The enzyme mass is wholly or partly inhibited by setting a pH value outside the activity optimum of the enzymes; (b) The reaction mixture, together with the inhibited enzyme mass, is subjected to filtration, obtaining a retentate (R1) and a permeate (P1); (c) The inhibited amount of enzymes is separated as a retentate (R1) and is fed back to step (iii); and (d) The permeate (P2) containing the galactooligosaccharides

Abstract: What are proposed are low-calorie food products comprising or consisting of (a) at least one milk component and (b) specific galactooligosaccharides (GOS).

Abstract: What are proposed are prebiotic formulations comprising or consisting of (a1) milk proteins and/or (a2) plant proteins and (b) oligosaccharides selected from the group formed by beta-galactooligosaccharides (?-GOS), alpha-galactooligosaccharides (?-GOS), fructooligosaccharides (FOS) and mannanoligosaccharides (MOS).
