Galacto-oligosaccharide

Galacto oligosaccharide (GOS) is a kind of functional oligosaccharides with natural properties. The molecular structure of this galactooligosaccharides supplement is generally connected with 1~7 galactosyl groups on galactose or glucose molecules, namely Gal-(Gal)n -Glc/Gal (n is 0-6). In nature, galacto oligosaccharides in baby formula take up a small amount animal milk, while human breast milk contains more. The establishment of bifidobacteria flora in infants largely depends on the GOS components in breast milk. In nature, there are trace amounts of galacto-oligosaccharides in animal milk, and a little more in breast milk. The sweetness of galacto oligosaccharide is relatively pure, with a low calorific value (7.1J/g), and the sweetness of galacto oligosaccharide is 20% to 40% of that of sucrose, and it has strong moisturizing properties. The prebiotic galacto oligosaccharide has high thermal stability under neutral pH conditions. After heating at 100°C for 1 hour or 120°C for 30 minutes, there is no decomposition of galactooligosaccharides. Galacto oligosaccharide powder and protein heat together to cause Maillard reaction, which can be used as a kind of galacto oligosaccharides food sources such as bread and pastry.
