Polysorbate 80 is a nonionic surfactant and emulsifier derived from polyethoxylated sorbitan and oleic acid, and is often used in foods. It can be used as a foaming agent to make spumas or airs. It is also added as an emulsifier in foods, particularly in ice cream, where polysorbate is added to up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting. Polysorbate prevents milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.
Warning: If you are using polysorbate in any food application, make sure you the using food grade version sold here. Do not buy cheaper cosmetic grade which is widely available for use in soaps and other beauty applications.
