E403 Ammonium Alginate

What is Ammonium alginate (E403)?

Ammonium alginate (E403) is a thickening and gelling agent derived from brown seaweed. It is commonly used in food products such as jellies, sauces, and dressings to enhance texture and stability. Ammonium alginate helps retain moisture, which makes it useful in processed foods like frozen desserts or canned products.


Why do I have an intolerance?

Intolerance to ammonium alginate might arise from sensitivity to its seaweed origin or to the ammonium salts present. These compounds can cause digestive issues, such as bloating, gas, or diarrhea in some individuals. In rare cases, it can trigger allergic-like symptoms due to the body’s sensitivity to the chemical makeup.


What can I do about it?

If you experience discomfort after consuming foods containing ammonium alginate, carefully check ingredient lists and avoid processed foods that use this additive. Opt for fresh, whole foods, and seek alternatives to processed thickeners.
