Kappa Refined Carrageenan: E407

Kappa Carrageenan is white translucent tasteless strip or powder. Melting point is 80 ℃. 1% carrageenan aqua can become glue gum liquid, and solid after cooling off, gel has the flexibility. It is obtained by aqueous extraction of natural strains of seaweeds of Gigartinaceae, Solieriaceae, Hypneaceae and Furcellar iaceae, families of the class Rhodophyceae (red seaweeds). No organic precipitant shall be used other than methanol, ethanol and propane-2-ol. Carrageenan consists chiefly of potassium, sodium, magnesium and calcium salts of polysaccharide sulphate esters which, on hydrolysis, yield galactose and 3, 6-anhydrogalactose. Carrageenan shall not be hydrolysed otherwise chemically degraded.
