Abstract
The invention relates to the field of nutritional ingredients, in particular to methods for producing hypoallergenic galacto-oligosaccharides (GOS) and the use thereof in food and drink items. Provided is the use of a beta-galactosidase (EC 3.2.1.23) derived from Cryptococcus terrestris (recently renamed Papiliotrema terrestris) in the production of a hypoallergenic GOS preparation having a reduced capacity to induce an allergic response in a subject.
Claims6
A method of at least partially preventing an allergic response to a galacto-oligosaccharide (GOS) preparation in a subject, the method comprising administering to the subject a hypoallergenic GOS preparation obtained by transgalactosylation of lactose using a Cryptococcus terrestris beta-galactosidase having EC 3.2.1.23, wherein the subject is known to suffer from or has hypersensitivity to a GOS preparation obtained by transgalactosylation of lactose using a Bacillus circulans beta-galactosidase.
