What Is Carrageenan E407?

Carrageenan E407 is a family of linear sulfated polysaccharide present in certain species of red seaweed. Carrageenan E407 is made up of repeating units of sulfated D-galactoseand 3,6-anhydro-D-galactose. Carrageenan E407 is a thickener made from seaweed used as gelling agent, stabilizer and thickener.


There are three types of Carrageenan, which differ in their degree of sulfation. Kappa Carrageenan has one sulfate group per disaccharide, Iota Carrageenan has two sulfates and Lambda-carrageenan has three.

Carrageenan E407 is a food thickener that can be used in food as a stabilizer and thickener. Carrageenan is used to improve the texture, taste, and appearance of many foods. Carrageenan can be classified as there types according to the seaweed source: Kappa, iota and lambda carrageenan. Carrageenan can be classified two types based on manufacturing process: Semi-refined and Refined Carrageenan.

Carrageenan E407 is a vegetarian and vegan alternative to gelatin in some applications or may be used to replace gelatin in confectionery.

Carrageenan has a synergy effect with other hydrocolloids like konjac gum.

Carrageenan E number:E407a or E407

Where does Carrageenan E407 comes from?

It comes from seaweed. There are three Types of Carrageenan classified from the seaweed source: Kappa Carrageenan: source from Cottonii seaweed, IOTA CARRAGEENAN: source from Spinosum seaweed, LAMBDA CARRAGEENAN from Gigartina. The largest commercial source of kappa seaweed is in Philippines where the weed is actually farmed rather than wild harvested.

There are two Types of carrageenan classified from extraction process: Refined Carrageenan and Semi Refined Carrageenan. 90% percent of Kappa and Iota Carrageenan is harvested in Philippines. The seaweed for Kappa and Iota are planted in warm water such as in Philippines. LAMBDA CARRAGEENAN can only plant in cold water, most planted in South America.
