Abstract
Abstract Water-soluble knojac 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 has utility as a food and exhibits a depressant effect on the serum cholesterol value in warm-blooded animals.
