Xanthan Carrageenan

Xanthan gum and carrageenan are both common food additives used to thicken, stabilize, and emulsify foods. Xanthan gum is produced by a bacterium called *Xanthomonas campestris*, while carrageenan is derived from red seaweed. Both are processed into powders that are then added to food products.

Manufacturers add xanthan gum and carrageenan to improve the texture and consistency of foods, preventing ingredients from separating. They are often found in dairy products like ice cream and yogurt, as well as sauces, dressings, and baked goods.

Both xanthan gum and carrageenan are approved for use in the U.S. by the FDA. Xanthan gum is generally recognized as safe (GRAS). Carrageenan is also permitted as a food additive. International bodies like JECFA and EFSA have evaluated both substances. Some studies have raised questions about potential digestive effects of carrageenan at very high doses, but regulatory bodies have not set specific limits for typical consumption.
