Is Sorbitan Monostearate Gluten Free?

Sorbitan monostearate, also known as E491, is a non-ionic surfactant often used as an emulsifier in food products to stabilize mixtures that would otherwise separate. It is synthesized from the reaction of sorbitol and stearic acid, which can be derived from both animal fats and plant oils. Commonly found in baked goods, margarine, and confectionery, it helps improve texture and extend shelf life.
