Propylene Glycol Mono & Diesters

Propylene glycol mono- and diesters are a group of emulsifiers made from propylene glycol and fatty acids. These fatty acids can come from plant or animal sources. They are produced through a process called esterification.

These ingredients help blend oil and water in foods, creating a smoother texture and preventing separation. They are commonly found in baked goods like cakes, cupcakes, muffins, and croissants, acting as emulsifiers and improving dough conditioning.

Propylene glycol mono- and diesters are generally recognized as safe (GRAS) by the FDA for use in food. They are metabolized by the body similarly to fats. International bodies like JECFA and EFSA have evaluated these substances. Evidence does not suggest adverse health effects at typical consumption levels.
