Food additives Europe numbers: E472b
Lactic acid esters of mono- and diglycerides of fatty acids, also known as Lactem or E472b, is a common food excipient used for various purposes. Here's a breakdown of its properties and functionalities:
- Composition: It's a mixture formed by combining lactic acid with monoglycerides and diglycerides, which are derived from fats and oils.
- Function: Lactem acts as a versatile food additive with several beneficial effects:
- Emulsifier: Perhaps its most important function is to help stabilize emulsions, which are mixtures of ingredients that wouldn't normally blend well, like oil and water. Lactem helps prevent separation and creates a smooth, consistent texture in foods.
- Wetting Agent: It improves the ability of water to interact with other ingredients in the food, promoting better mixing and dispersion.
- Aerating Agent: Lactem can help incorporate air into food products, leading to a lighter texture and increased volume, useful in baked goods and whipped products.
- Stabilizer: It can improve the overall stability and shelf life of food by preventing separation, crystallization, or other undesirable changes in texture.
- Safety: Generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices and within limitations.
- Applications: Lactem is widely used in various food products, including:
- Baked goods (cakes, breads, pastries) - for improved texture, volume, and crumb structure.
- Fats and oils (mayonnaise, margarine) - for better emulsification and stability.
- Confectionery (candy, icings) - for smoother texture and aeration.
- Dairy products (ice cream, whipped cream) - for better texture, stability, and whipping ability.
- Meat products - for improved moisture retention and texture.
