E491 Sorbitan monostearate

What is E491 or Sorbitan monostearate?

E491, or sorbitan monostearate, is a synthetic emulsifier made by combining sorbitol, a sugar alcohol, with stearic acid, a fatty acid. It is used in a variety of processed foods to improve texture and maintain the stability of oil and water mixtures. You might find E491 in baked goods, whipped toppings, and confectionery.

Why do I have an intolerance?

Intolerance to E491 may arise from your body's inability to properly digest sorbitol or stearic acid. Sorbitol can cause gastrointestinal discomfort, especially in people who are sensitive to sugar alcohols. Reactions to stearic acid, which can be derived from animal or plant sources, might also contribute to symptoms like bloating, nausea, or diarrhea.

What can I do about it?

If you have an intolerance to E491, avoid processed foods that contain this additive. Checking food labels for sorbitan monostearate and selecting products that use natural emulsifiers can help prevent symptoms. Opting for homemade or less processed alternatives can also help you steer clear of this additive.
