Overview

Description

ι-Carrageenan has many advantages over κ-Carrageenan. The gel formed by the interaction of ι-Carrageenan with calcium ions is soft, elastic, thixotropic and anti-melt stable, and also has good water retention. ι-Carrageenan is soluble in hot water and its sodium salt is soluble in cold water. However, ι-Carrageenan is hardly soluble or insoluble in cold milk, mainly because the higher the content of 3,6-lactone-galactose and the lower the content of sulfate group, the more difficult it is to dissolve in cold milk. Both ι-Carrageenan and λ-Carrageenan are insoluble in organic solvents. As a renewable natural polysaccharide polymer, ι-Carrageenan has the advantages of naturalness, safety and abundant sources, and is widely used in the fields of food, cosmetics, biomedicine and paints and coatings.
