Dietary Fiber Fructan

Fructans are a type of soluble fiber made of chains of fructose sugar molecules. They are found naturally in many fruits, vegetables, and grains, such as onions, garlic, bananas, and wheat. Industrially, they are often extracted from chicory root or produced through enzymatic processes.

Fructans are added to foods as a source of dietary fiber and as a prebiotic, meaning they can feed beneficial bacteria in the gut. They can also act as a fat replacer or sugar substitute, providing sweetness and texture. They are commonly found in energy bars, baked goods, and dairy products.

Fructans are recognized as dietary fiber and are generally considered safe for consumption. The FDA recognizes inulin and fructooligosaccharides (FOS), common types of fructans, as Generally Recognized As Safe (GRAS) for specific uses. While generally beneficial for gut health, some individuals may experience gas or bloating when consuming large amounts of fructans, especially if their digestive system is not accustomed to them. JECFA and EFSA have evaluated various fructans, acknowledging their role as dietary fiber.
