Isomaltooligosaccharides

Isomaltooligosaccharides (IMO) are a type of carbohydrate, often referred to as a prebiotic fiber. They are typically produced from starch, commonly from corn or tapioca, through enzymatic processes. This process breaks down the starch and rearranges it into short chains of glucose molecules linked in a way that resists digestion.

Manufacturers use IMO primarily as a sweetener and a source of dietary fiber. Because they are less sweet than regular sugar and provide a chewy texture, they are often found in snack bars, baked goods, and confectionery. They can also help improve the texture and moisture retention of foods.

Isomaltooligosaccharides are generally recognized as safe (GRAS) by the FDA for use in food. They are considered a prebiotic fiber, which may support gut health by feeding beneficial bacteria in the digestive system. Some studies suggest they may have a lower impact on blood sugar levels compared to other sugars. JECFA has evaluated IMO and established a group ADI for certain oligosaccharides. Evidence on the specific health effects of IMO is still developing.
