Abstract :Beta-Galacto-oligosahaarides insert ignore into journalissuearticles values(β-GalOS); are naturally occurred in milk at low concentration, and are found in all dairy products. ß-GalOS are commercially produced enzymatically by trans glalactosylation of milk sugar lactose as a substrate using the microbial enzyme ß-galactosidase insert ignore into journalissuearticles values(EC 3.2.1.23); derived from bacteria, yeasts or molds. ß-GalOS are one of functional oligosaccharides and are known by different names as oligogalactosyllactose, oligogalactose, oligolactose, tranas-galactosylated oligo- saccharide, and transgalacto-oligosaccharide. Chemical structures of ß-GalOs are chain of galactose units that arise through consecutive transgalactosylation enzymatic reactions, linked together into terminal glucose unit in the disaccharide lactose. The degree of galactose polymerization in ß-GalOS are vary and ranging from 2 to 8 galactose units. This degree of polymerization depends on the property and source of the enzyme ß-galactosidase used in the process. ß-GalOS are pass undigested into the colon where increase bowel mass and act as prebiotics insert ignore into journalissuearticles values(growth factor); for good bacteria insert ignore into journalissuearticles values(probiotics); in the colon. ß-GalOS are commonly used for stomach disorders such as constipation and preventing from allergies specially for infants. It is also, reported that ß-GalOS can prevent consumers from colon cancer and rectal cancer.
