What is "Carrageenan"?
Carrageenan is a soluble fiber extracted from red seaweed. The red seaweed Chondrus crispus contains 55% carrageenan. It is a sulfated galactan that has the property of forming a gel. There are three types of carrageenan: kappa, lambda, and iota. The kappa and iota carrageenans are from the red seaweed Chondrus crispus.
Carrageenan is extracted in two ways. The first involves converting the seaweed into a solution, then the residues are filtered out, leaving only pure carrageenan. The second method involves mixing the seaweed with an alkaline solution to yield carrageenan and cellulose.
What is the usefulness of "Carrageenan"?
Extracted from red algae, carrageenan is used as athickening, gelling, and stabilizing agent. It is particularly used in the food industry, but also in the formulation of body care products. Used as a food additive, it is included in the composition of jams, jellies, dairy products, and even meat-based products. It is also incorporated into certain body creams, lotions, and hair care products.
