Isomaltooligosaccharide is produced by enzymatic transglucosylation of starch-derived glucose using α-transglucosidase, rearranging α-1,4 linkages into α-1,6 bonds that resist human digestion.
Standard grades include IMO-50, IMO-90, and IMO-900 (powder, ≥90% IMO). It delivers partial prebiotic function, 40–60% sucrose sweetness, and clinically demonstrated digestive comfort.
