Short-chain Fructooligosaccharides

Short-chain fructooligosaccharides (scFOS) are a type of carbohydrate made up of short chains of fructose sugar molecules. They are often produced commercially by enzymatic conversion of sucrose or from chicory root. scFOS are considered a type of prebiotic fiber.

Manufacturers add scFOS to foods as a low-calorie sweetener and to improve texture. They are also used to increase the fiber content of products. scFOS can be found in a variety of foods, including baked goods, dairy products, beverages, and nutritional supplements.

In the U.S., scFOS are generally recognized as safe (GRAS) by the FDA for use in certain food categories. They are not digested in the small intestine and reach the colon, where they can be fermented by beneficial gut bacteria. Some studies suggest potential benefits for gut health, but research is ongoing. JECFA and EFSA have evaluated scFOS and established acceptable daily intakes.
