Description
Using lactose in milk as raw material, β-galactosidase catalyzes hydrolysis of galactosidic bonds to generate galactose and glucose, and the hydrolyzed galactosides are transferred to lactose molecules to generate galacto-oligosaccharides. It is a prebiotic that cannot be absorbed by the human body, but can promote the growth and activity of probiotics in the intestine, so it is often used in milk products for infants and adults.
