Carrageenan is obtained by extraction with water or alkaline water of certain species of the class Rhodophyceae (red seaweed). It is a hydrocolloid consisting mainly of the potassium, sodium, magnesium, and calcium sulfate esters of galactose and 3.6-anhydro-galactose copolymers. The relative proportion of cations existing in carrageenan may be changed during processing to the extent that one may become predominant.
Carrageenan is recovered by alcohol precipitation, by drum drying, or by freezing. The alcohols used during recovery and purification are restricted to methanol, ethanol, and isopropanol.
The commercial products classified as carrageenan are frequently diluted with sugars for standardization purposes and mixed with food grade salts required for obtaining gelling or thickening characteristics.
Red seaweed are growing in importance as carrageenan raw materials, improving stability of supply and broadening the range of properties which can be achieved. Important species are Eucheuma cottonii, which yields kappa-carrageenan, and Eucheuma spinosum which yields iota-carrageenan. These Eucheuma species are harvested along the coasts of the Philippines and Indonesia.
