Is carrageenan gluten-free?

Yes, carrageenan is gluten-free. Carrageenan, a substance derived from red edible seaweeds, is utilized broadly in the food industry as a stabilizer, emulsifier, or thickener. It does not contain gluten as it is not derived from gluten-containing grains like wheat, barley, or rye, and hence is safe for those following a gluten-free diet to consume.
