What it is
Carrageenan is a common food additive derived from red seaweed. It is extracted from the seaweed using an alkali treatment process, resulting in a powder that is then used in food production.
Why it's used
Manufacturers use carrageenan primarily as a thickener and stabilizer. It helps to give foods a desirable texture and prevent ingredients from separating. It is commonly found in dairy products like ice cream, yogurt, and processed cheese, as well as in some non-dairy milk alternatives.
Health notes
In the United States, carrageenan is generally recognized as safe (GRAS) by the FDA for use as a food additive. Regulatory bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated carrageenan. Some studies have raised questions about potential digestive issues or inflammation associated with degraded carrageenan, but the scientific consensus, based on evaluations by these bodies, is that food-grade carrageenan is safe at typical consumption levels.
Allergen info
Carrageenan is derived from seaweed and is not one of the nine major allergens recognized by the FDA. It does not contain gluten.
