What it is
Carrageenan is a common food additive derived from red seaweed. It is extracted from the seaweed using an alkali process, then dried and powdered. It is a vegetarian and vegan ingredient.
Why it's used
Carrageenan is used as a thickener, stabilizer, and emulsifier in many food products. It helps prevent ingredients from separating and gives foods a desirable texture. It is often found in dairy products like ice cream and yogurt, as well as in processed meats and beverages.
Health notes
In the U.S., carrageenan is generally recognized as safe (GRAS) by the FDA for use in food. It has been evaluated by international bodies like JECFA and EFSA. Some studies have raised questions about potential health effects, particularly concerning inflammation and digestive issues, but the evidence is mixed and often based on studies using degraded carrageenan, which is not permitted in food. Regulatory bodies consider food-grade carrageenan 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.
