Product Introduction
Galacto-oligosaccharides (GOS) is a naturally occurring functional oligosaccharide. Its molecular structure typically consists of 1 to 7 galactose units linked to a glucose or galactose molecule, represented as Gal-(Gal)n-Glc/Gal (where n is 0-6). GOS occurs naturally in small amounts in animal milk, with a higher concentration in human breast milk, which is crucial for establishing the bifidobacteria population in infants.GOS is produced from lactose in cow's milk through enzymatic hydrolysis using β-galactosidase, which breaks down the galactosidic bonds to generate galactose and glucose. The hydrolyzed galactosides are then transferred to lactose molecules, forming a colorless transparent or light yellow syrup.Naturally occurring in animal milk, GOS is present in higher amounts in human milk. GOS has a pure sweet taste, low caloric value, and a sweetness level of 20% to 40% of sucrose. It has excellent moisture retention properties and high thermal stability under neutral pH conditions. GOS does not decompose when heated at 100°C for 1 hour or at 120°C for 30 minutes. When heated with proteins, GOS can undergo a Maillard reaction, making it suitable for processing special foods like bread and pastries.The Ministry of Health of the People's Republic of China approved GOS as a new food resource in its 2008 Announcement No. 20, specifying its usage standards.
Production Process
Lactose from cow's milk is used as the raw material. It is enzymatically hydrolyzed using β-galactosidase to break the galactosidic bonds, generating galactose and glucose. The hydrolyzed galactosides are then transferred to lactose molecules, forming GOS.
Benefits and Effects
GOS is an oligosaccharide composed of galactose molecules and offers various benefits and effects:
Gut Health Maintenance: GOS can be utilized by probiotics in the human gut, promoting the growth of beneficial bacteria, inhibiting harmful bacteria, maintaining gut flora balance, and improving gut health.
Immune System Enhancement: GOS has immunomodulatory effects, increasing the number and activity of immune cells, boosting the body’s resistance to infections and diseases.
Calcium Absorption Promotion: GOS enhances calcium absorption in the intestines, improving calcium utilization and helping prevent osteoporosis and other calcium-related conditions.
Blood Sugar Regulation: GOS regulates blood sugar release and utilization, lowering blood sugar peaks and fluctuations, aiding in the prevention and management of diabetes.
Intestinal Motility Promotion: GOS increases water content in the intestines, enhancing intestinal motility, aiding digestion and excretion, and preventing constipation and other digestive disorders.
Overall, GOS contributes to gut health, immune system enhancement, calcium absorption, blood sugar regulation, and intestinal motility, offering positive impacts on overall health.
Food Applications:
GOS can be used in health foods, functional foods, and as a food additive.
