Fructooligosaccharide (FOS)
Fructooligosaccharides (FOS) are short-chain fructans used as prebiotic carbohydrates in foods, beverages, and dietary supplements. In industrial practice, “FOS” typically refers to a defined mixture of low–degree-of-polymerization fructose oligomers that resist hydrolysis by human small-intestinal enzymes and reach the colon largely intact, where they serve as fermentable substrates for selected gut microbes.
