Sorbitan Monostearate and the Alpha-Gal Friendly Diet
Sorbitan monostearate, also known as E491, is a synthetic compound used as an emulsifier in a variety of food products. It helps to blend ingredients that typically do not mix well, such as oil and water. This ingredient is produced by the esterification of sorbitol with stearic acid, which can be derived from either animal or plant sources. Due to its dual sourcing, individuals with specific dietary restrictions, such as those avoiding animal-derived products, should verify the source of the stearic acid used in its production.
