Propylene Glycol Mono Fatty Acid Esters

Propylene glycol mono fatty acid esters are a group of compounds made from propylene glycol and fatty acids. Fatty acids are typically derived from vegetable oils or animal fats. The process involves reacting these components together.

These esters are used as emulsifiers in baked goods like cakes and cupcakes. They help ingredients like oil and water mix together, creating a smoother texture and improving shelf life. They can also act as dough conditioners.

In the United States, propylene glycol mono fatty acid esters are generally recognized as safe (GRAS) by the FDA for use as emulsifiers. Regulatory bodies like JECFA and EFSA have evaluated similar substances. At typical consumption levels found in food, they are not associated with adverse health effects.
