Carrageenan

Product Description

1.REFINED CARRAGEENAN
Carrageenan 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.

2.SEMI REFINED CARRAGEENAN
Treatment of the natural strains of seaweed Eucheuma cottonii of the class Rhodophyceae (red seaweeds) remove impurities and fresh water washing and drying to obtain the product. Further purification may be achieved by washing and drying. The product consists chiefly of the potassium salts of polysaccharide sulphate esters which on hydrolysis, yield galactose and 3,6-anhydrogalactose. Sodium, calcium and magnesium salts of the polysaccharide sulphate esters are present in less amount. Up to 15 % algal cellulose is also present in the product. The carrageenan in processed eucheuma seaweed shall not be hydrolyzed otherwise chemically degraded.
