Carrageenan Carrageenan Carrageenans or carrageenins ( , from Irish "", "little rock") are a family of linear sulfated polysaccharides that are extracted from red edible seaweeds. They are widely used in the food industry, for their gelling, thickening, and stabilizing properties. Their main application is in dairy and meat products, due to their strong binding to food proteins. There are three main varieties of carrageenan, which differ in their degree of sulfation. Kappa-carrageenan has one sulfate group per disaccharide, iota-carrageenan has two, and lambda-carrageenan has three. Gelatinous extracts of the "Chondrus crispus" (Irish moss) seaweed have been used as food additives
Carrageenan in an array of agricultural products, and public comments reported that potential substitutes do not adequately replicate the functions of carrageenan across the broad scope of use. Therefore, carrageenan continues to meet the OFPA criteria for inclusion on the National List.” The rule went into effect May 29, 2018. In the most recent review by an independent panel, the Joint Expert Committee of the Food and Agriculture Organization of the United Nations and World Health Organization on Food Additives released a technical report in 2015 on the use of carrageenan in infant formula and found that the additive was ‘not
