Fortunately, there are a few simpler synonyms that can help make it easier to understand - these include IMO, isomaltodextrin, and alpha-glucosidase. Each of these terms refers to the same carbohydrate compound, which is derived from natural starch sources such as tapioca or corn. Not only is it an effective sweetener, but it also acts as a prebiotic and can help improve gut health. Despite its complex name, isomaltooligosaccharide is a versatile ingredient that can be used in many food and beverage applications.
