Sorbitan Monooleate and the Vegan Diet

Sorbitan Monooleate, commonly referred to as Polysorbate 80, is a synthetic compound used as an emulsifier in the food industry. It is a derivative of sorbitol and oleic acid and is widely used to stabilize oil-in-water mixtures, preventing separation in processed foods. The ingredient can be sourced from either plant or animal fats, which can be a concern for vegans and vegetarians.
