Overview
Description

Carrageenan is a hydrophilic colloid that is extracted from red algae seaweeds such as unicornia, celery, and carrageen. Their chemical structures are calcium, potassium, sodium and ammonium salts of polysaccharide sulfates composed of galactose and anhydrogalactose. Carrageenan can be divided into 7 types, including K-type (Kappa), I-type (Iota), and L-type (Lambda), according to the different positions where the half-ester sulfate group is attached to galactose. The gel properties of carrageenan are mainly related to its chemical composition, structure and molecular size. Based on the properties of carrageenan, they are widely used in the food industry, medicine and other fields.
