Konjac Root Flour

Konjac root flour comes from the ground root of the konjac plant, native to Asia. The root is a source of glucomannan, a soluble dietary fiber. The flour is typically made by drying and grinding the konjac root.

Konjac root flour is primarily used as a thickener and gelling agent in foods. Its high viscosity and water-binding capacity make it useful in low-calorie products, desserts, and as a meat or fat substitute. It is often found in "healthy" snacks, noodles, and jellies.

Konjac root flour is recognized as Generally Recognized As Safe (GRAS) by the FDA for use as a food ingredient. As a soluble fiber, it can contribute to feelings of fullness and may help with digestive regularity. International bodies like JECFA and EFSA have evaluated glucomannan, noting its fiber properties. Some studies suggest it may have a role in managing blood sugar and cholesterol levels, though more research is needed to confirm these effects.
