Updated National List Includes Carrageenan

The U.S. Department of Agriculture (USDA) has announced the renewal of 17 substances for the National List of Allowed and Prohibited Substances, which determines which synthetic substances can be used in organic farming. Included on the list is carrageenan; USDA found that “potential substitutes do not adequately replicate the functions of carrageenan across the broad scope of use.” The National Organic Standards Board previously recommended that carrageenan be removed from the National List, determining that materials such as guar gum and xanthan gum were available for use as alternative thickening and emulsifying agents.
