Galacto-oligosaccharide（GOS, is a natural functional oligosaccharide, which exists in animal milk. Using lactose as raw material and by the action of β-galactosidase,the oligosaccharide mixture of galactose molecule is linked by β(1-4),β(1-6) and β(1-3) bonds on the galactose group in the molecule of lactose. Galacto oligosaccharides in baby formula can be widely seen in the market because it is helpful to improve the constipation and poor calcium absorption of non breastfeeding infants, and to improve the nutritional and health status of infants.

APPLICATION:
Because of its special properties and , galactooligosaccharide has been widely used in dairy products, beverages, bakeries, health products, and so on.
FUNCTION:
Sweetness is 30%-40% of sucrose, and the sweetness is soft and pure
Higher viscosity than sucrose(75Brix at the same sugar degree)
Be stable under high temperature and acidic conditions(pH3.0,160℃，15 min)
Good moisture retention and can not only provide soft sweetness but also prolong shelf life when added to the baking products.
PHYSICAL PROPERTIES:
Regulate intestinal flora, increase beneficial bacteria, reduce harmful bacteria
Enhance immunity, prevent allergies, reduce infectious diseases
Improve lactose intolerance; improve blood lipids, reduce total cholesterol and triglyceride
Increase high-density lipoprotein cholesterol; promote mineral absorption
