Food additives Europe numbers: E477
Lactylated fatty acid esters of glycerol and propane-1, also known as Lactelate esters of glycerol and propanol (LAC) or E477, is a food excipient used for its emulsifying and stabilizing properties. Here's a breakdown of its key characteristics:
- Function: LAC acts primarily as an emulsifier, helping to evenly distribute and stabilize mixtures of ingredients that wouldn't normally blend well together, like oil and water. This creates a smooth and consistent texture in food products.
- Chemical Composition: LAC is a combination of lactic acid (derived from fermentation processes like pickling) esterified with fatty acids (from oils) and glycerol or propanol (short-chain alcohols).
- Applications: LAC finds use in a variety of food products where good emulsification and stability are desired, including:
- Bakery items (cakes, breads, pastries): LAC can improve crumb texture and moisture retention.
- Fats and spreads (mayonnaise, margarine): It aids in creating stable emulsions, preventing oil separation.
- Confectionery (candy, icings): LAC contributes to smoother textures and prevents sugar crystallization.
- Beverages (coffee creamer, flavored milks): It helps disperse fats or oils evenly throughout the beverage.
- Meat products: LAC can improve moisture retention and texture in processed meats.
- Safety: Generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices and within limitations.
- Natural Occurrence: LAC itself isn't naturally occurring, but its building blocks (lactic acid, fatty acids, glycerol/propanol) come from natural sources like vegetables, milk fats, and fermentation processes.
- Similarities and Differences to Lactem (E472b): LAC shares some functionalities with Lactem (Lactic acid esters of mono- and diglycerides of fatty acids), another common emulsifier. However, there are key differences:
- LAC uses propanol in addition to glycerol, while Lactem does not.
- LAC might have a slightly different range of applications compared to Lactem due to its specific chemical structure.
