MILK PRODUCTS COMPRISING HIGH AMOUNTS OF GALACTOOLIGOSACCHARIDES (GOS) AND THEIR PRODUCTION

The present invention relates to milk products comprising a high amount of in situ produced galactooligosaccharides (GOS) and methods of producing same. Milk substrate having a lactose content of at least 20wt% lactose is treated with an enzyme having transgalactosylating activity. The transgalactos...

description The present invention relates to milk products comprising a high amount of in situ produced galactooligosaccharides (GOS) and methods of producing same. Milk substrate having a lactose content of at least 20wt% lactose is treated with an enzyme having transgalactosylating activity. The transgalactosylating activity of said enzyme may have been increased via glycation of lysine and/or arginine residues by incubation of said enzyme with high concentrations of glucose at elevated temperatures. La présente invention concerne des produits laitiers comprenant une grande quantité de galacto-oligosaccharides (GOS) produits in situ, et leurs procédés de production. Un substrat de lait ayant une teneur en lactose supérieure ou égale à 20 % en poids de lactose est traité par une enzyme présentant une activité de transgalactosylation, l'activité de transgalactosylation de ladite enzyme ayant été augmentée par la glycation de résidus de lysine et/ou d'arginine par incubation de ladite enzyme avec des concentrations élevées de glucose à des températures élevées.
