konjac powder

Konjac is a plant found in the warm subtropical and tropical eastern Asia, from Japan and China to Indonesia. Konjac flour or Glucomannan is a natural, odorless soluble fiber that is found in the konjac plant. It has been known in Japan since the sixth century as a medicinal food, and it has been eaten for 1,500 years.

It has the highest density and strongest viscosity of any dietary fiber in nature. It absorbs 10 times as much water as cornstarch, but it is a soluble fiber which does not contain starch and sugar. It has almost no calories, but is very high in fiber, therefore it is often used as a diet food.
