Galacto-oligosaccharide Powder

Galacto-oligosaccharide Powder

Galacto-oligosaccharide (GOS) powder, 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. The galacto oligosaccharide powder (gos powder) is helpful to improve constipation and poor calcium absorption of non-breastfeeding infants, and to improve the nutritional and health status of infants.

Applications of Galacto-oligosaccharide Powder

Because of its special properties, galacto oligosaccharide powder has been widely used in dairy products, beverages, bakeries, health products, and so on.

Functions of Galacto-oligosaccharide Powder

Sweetness of gos powder is 30%-40% of sucrose, and the sweetness is soft and pure

Higher viscosity than sucrose(75Brix at the same sugar degree)

Galactooligosaccharides powder is 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 baking products.

Physical Properties of Galacto-oligosaccharide Powder

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
