A PREPARATION METHOD OF GALACTOOLIGOSACCHARIDES WITH ENHANCED GALACTOSYLLACTOSE WHICH IS A INGREDIENT OF MOTHER'S MILK

摘要

The present invention is relates to a manufacturing method of galactooligosaccharides having 50 wt% of galactosyllactose contents using an enzyme. The present invention comprises: a step of dissolving lactose in water; a step of adding lactase and beta-galactosidase in the lactose solution, allowing enzyme reaction and then additionally adding yeast; and purifying enzyme reaction solution which the yeast is added. [Reference numerals] (AA) Lactose; (BB) Melting(40-45%); (CC) Enzyme reaction/Yeast reaction; (DD) Powder activated carbon(discoloration); (EE) Filter sugar solution; (FF) Ion exchange resin(purify); (GG) Bactericidal/Concentration; (HH) Galactosyllactose(liquid products); (II) Drying(spray drying); (JJ) Galactosyllactose(powder products)
