Process for enhancing the natural bile acid binding capacity of edible pulp material by either heating an aqueous slurry of the pulp material to at least 40.degree. C. and/or sequentially reacting pulp with a first reactant, such as sodium hydroxide, for activating the pendant hydroxyl groups on the polysaccharide components of the pulp material, a second reactant, such as chloroacetic acid, for carboxylating the activated pendant groups on the polysaccharides, and a third reactant, such as calcium hydroxide, for providing calcium ions which can ionically bond to the carboxylated pendant groups.
