Effect of Metal Cations on the Gel-Forming Ability and Solubility of the Polysaccharide κ-Carrageenan
摘要
Seaweed has recently become a rich source of valuable materials. Research showed that κ-carrageenan was insoluble in organic solvents and very soluble in water and inorganic solvents. The effects of alkali-metal cations on the gel-forming ability of the polysaccharide have been studied. The film- forming ability of κ-carrageenan was studied. The dissolution time of the film was found.
