Bifidus active hypoallergenic GOS composition and its providing method involving beta-galactosidase from a strain of Lactobacillus delbruecki SSP bulgaricus

摘要

The present invention relates to the field of low allergic oligosaccharides for use in nutritional compositions, in particular to oligosaccharides having prebiotic properties. There is provided a low allergic oligosaccharide composition comprising galacto-oligosaccharide (GOS), wherein (i) the galacto-oligosaccharide (GOS) content is at least 40% by weight of the total dry matter of the composition; (ii) the allolactose content is at least 10% by weight of the total dry matter of the composition; (iii) the 6'-GL content is at least 30% by weight of the total GOS in the composition; (iv) At least 0.5% by weight of the total GOS has a degree of polymerization (DP) of 6 or more. The GOS composition does not trigger GOS-allergies as evaluated in the basophil activation test (BAT).
