Lambda does not gel, and is used to thicken dairy products.It is produced mainly from Eucheuma denticulatum. Iota forms soft gels in the presence of calcium ions.It is sourced mainly from Kappaphycus alvarezii.
Kappa forms strong, rigid gels in the presence of potassium ions, and reacts with dairy proteins.There are three main commercial classes of carrageenan: They are widely used in the food and other industries as thickening and stabilizing agents.Īll carrageenans are high-molecular-weight polysaccharides and mainly made up of alternating 3-linked b-D-galactopyranose (G-units) and 4-linked a-D-galactopyranose (D-units) or 4-linked 3,6-anhydro-a-D-galactopyranose (DA-units), forming the disaccharide repeating unit of carrageenans. This gives them the ability to form a variety of different gels at room temperature. Properties The molecular structures of different types of carrageenanĬarrageenans are large, highly flexible molecules that form curling helical structures. Carrageenan, along with agar, are used to produce traditional jelly desserts in the Philippines called gulaman. The global top producers of carrageenan are the Philippines and Indonesia. for carrageenan was developed in the Philippines.
The first industrial scale commercial cultivation of Eucheuma and Kappaphycus spp. There is no clinical evidence for carrageenan as an unsafe food ingredient, mainly because its fate after digestion is inadequately determined. Carrageenan is a vegetarian and vegan alternative to gelatin in some applications, so may be used to replace gelatin in confectionery and other food. Gelatinous extracts of the Chondrus crispus seaweed have been used as food additives since approximately the fifteenth century. The most well-known and most important red seaweed used for manufacturing the hydrophilic colloids to produce carrageenan is Chondrus crispus (Irish moss), which is a dark red parsley-like alga that grows attached to rocks. Kappa-carrageenan has one sulfate group per disaccharide, iota-carrageenan has two, and lambda-carrageenan has three. They can be mainly categorized into three different classes based on their sulfate content. Ĭarrageenans contain 15–40% ester- sulfate content, which makes them anionic polysaccharides. They have been mainly used for tissue engineering, wound coverage, and drug delivery. In recent years, carrageenans have emerged as a promising candidate in tissue engineering and regenerative medicine applications as they resemble native glycosaminoglycans (GAGs). Their main application is in dairy and meat products, due to their strong binding to food proteins. Carrageenans are widely used in the food industry, for their gelling, thickening, and stabilizing properties.
