Application

D-Galactose is a monosaccharide sugar that serves as an energy source and glycosylation component. It is a C-4 epimer of glucose and often used as a source of carbon in culture media. Galactose is a component of the disaccharide lactose and released upon hydrolysis by β-galactosidase enzymes. It is converted to glucose via the Leloir pathway or metabolized via an alternative pathway, such as the DeLey-Doudoroff pathway.

Galactose is important in enzymatic and biochemical research as a nutrient medium and as a synthesis module. also widely used in the pharmaceuticals sector, both as a carrier and as an active substance. D-galactose is particularly important as a precursor for pharmaceutically active substances, as an active substance carrier or also as a chiral module in chemical synthesis. However, in which galactose is synthesised from lactose on a large scale, there is always the problem of BSE-/TSE contamination.

Function:
1. Good taste:similar to sucrose in terms of taste.
2. Easily dissolved:dissolves quickly and easily in water under room temperature.
3. Non-calories:no metabolism and no calorific value in the body, suitable for diabetics.
4. Synergistic effect:  D-Galactose has a distinguished synergistic effect when used in combination with other sweeteners, which can make a 20-40% reduction in the quantity of product required.
5.Long-lasting stability: no loss quality for 10 years during storage, not hygroscopic, high physical and chemical stablity even at 225°c or the range of PH2-10, no interaction with other involved ingredients and additives.
