Product Introduction of Isomaltooligosaccharide

Isomaltooligosaccharide (IMO, CAS:5959-85-3, Molecular Formula: C₁₂H₂₂O₁₁) is linear short-chain prebiotic oligosaccharide manufactured via enzymatic hydrolysis and transglycosylation of corn or tapioca starch. Its molecular chain connects with α-1,6 glycosidic bonds, which cannot be digested and absorbed by human small intestinal enzymes, so it completely reaches the large intestine to nourish beneficial gut bacteria.
Our IMO powder presents white or light yellow fine powder with mild sweetness, only 40%-50% sweetness of sucrose and low glycemic index, avoiding sharp blood sugar spikes. The shelf life reaches 24 months under sealed, cool, dry and dark storage conditions.
