Abstract
Abstract Water-soluble konjac mannan capable of undergoing gelation when heated in an aqueous alkaline solution is obtained by extracting the ground tuber of the konjac plant with water, separating insoluble matter, dialyzing the solids-free liquid against water and then lyophilizing the dialyzed liquid to remove water. This konjac mannan extract has utility for alleviating constipation and reducing weight.
