physiological effect | raffinose is a functional oligosaccharide, which is not absorbed and decomposed by human gastrointestinal digestive juice, and can directly enter the large intestine through the stomach and small intestine. It is fermented and utilized by microorganisms. Its metabolic method directly enters the large intestine through the stomach and small intestine and is fermented and utilized by microorganisms. Its metabolic method is similar to dietary fiber. According to analysis, the energy value of raffinose is 6kJ/g. raffinose is an excellent nutrient source and effective proliferation factor for beneficial bacteria such as Bifidobacterium and Lactobacillus acidophilus in the human intestine. raffinose has the function of improving bowel and defecation. It can improve the digestive function of the human body and promote the absorption of calcium by the human body. So as to enhance human immunity. It has obvious effect on disease prevention and anti-aging. Raxinose can be used as the main component of the protective delivery solution for human and animal living organ transplantation and a synergist for prolonging the survival of live bacteria at room temperature. |

biological activity | Raffinose (Melitose) is an indigestible short-chain oligosaccharide, a trisaccharide composed of galactose, glucose and fructose, which can be found in many plants. Raffinose (Melitose) can be hydrolyzed by α-galactosidase (α-GAL) to D-galactose and sucrose. |
