Carrageenan is made up of sodium, potassium, magnesium and calcium sulfate esters of galactose and 3,6-anhydrogalactose units. It is a wholly natural ingredient obtained from certain species of the red seaweed, class Rhodophyceae. Popular sources for carrageenan are the Chondrus crispus, Eucheuma cottonii and Eucheuma spinosum species.
The seaweeds are harvested, cleaned and dried. The extraction is in alkali conditions at high temperature. The extract is then purified and converted to powder. There are three main varieties of carrageenan. Kappa-carrageenan , Iota-carrageenan and Lambda carrageenan each has a different structure and hence differing properties.
There are many different grades of carrageenan for different food and beverage applications and well as differing desired results. Let TIH help you select the right product.
