METHOD OF PREPARING SYRUP OF GALACTOOLIGOSACCHARIDES Russian patent published in 2000 - IPC

FIELD: food industry, particularly, technology of producing syrup of galactooligosaccharides. SUBSTANCE: method involves preparation of lactose aqueous solution with concentration of 40-70% at temperature 100-108 C. Mineral acid, hydrochloric one, for example, is introduced in the amount of 0.01-0.12 g/mole per 1 kg of lactose solution. Mixture is aged for 20-120 min at above-mentioned temperature for forming galactooligosaccharides. Prepared syrup is cooled and neutralized by alkali agent up to 4.5-6.5 pH. The proposed method provides for preparation of product with higher content of galactooligosaccharides. EFFECT: broadened assortment of food additives with bifidogenic properties. 2 ex
