Xanthan Gum Carrageenan

Xanthan gum is a polysaccharide produced by the fermentation of sugars by the bacterium Xanthomonas campestris. Carrageenan is a red seaweed extract. Both are used as food additives.

Xanthan gum and carrageenan are primarily used as thickeners and stabilizers in foods. They help improve texture and prevent ingredients from separating, commonly found in salad dressings, sauces, dairy products, and baked goods.

Xanthan gum and carrageenan are generally recognized as safe (GRAS) by the FDA. Both have been evaluated by JECFA and EFSA, with no numeric limits set for xanthan gum. Some studies suggest carrageenan may cause digestive issues in sensitive individuals, though evidence is mixed and more research is needed. Regulatory bodies consider them safe at typical consumption levels.
