Diacetylated glycerol (E477a) – what is it?
Diacetylated glycerol, designated as E477a, is a derivative of glycerol, which is one of the popular emulsifiers and stabilizers used in the food industry. It is formed by reacting glycerol with acetic acid and acetic acid anhydride, which gives it emulsifying properties. Diacetylated glycerol is used to stabilize and improve the texture of food products, especially where a combination of fat and water is required.
Properties of diacetylated glycerol (E477a)
E477a acts as an effective emulsifier that enables the formation of stable emulsions between fats and water. Thanks to this property, diacetylated glycerol is used in food products that require maintaining a homogeneous consistency for long periods of time. Diacetylated glycerol also helps prevent the stratification of fats in products such as margarines, sauces and creams. In addition, it is stable over a wide range of temperatures, which makes it useful in heat-treated food products.
Use in food products
Diacetylated glycerol (E477a) is widely used in the food industry, especially in the production of margarines, vegetable butter, creams, beverages and confectionery. In the baking industry, it helps improve the texture of dough, providing better elasticity and stability. Its use also extends to beverage production, where it helps create stable emulsions, especially in fat-based beverages such as plant milks and isotonic drinks.
Health benefits and safety of use
Diacetylated glycerol (E477a) is considered a safe food additive, used in strictly limited amounts. As a derivative of glycerol, it poses no health risk to consumers, and its use in food products does not adversely affect the caloric or fat profile of foods. Since it is mainly used as an emulsifier and stabilizer, it does not significantly affect the nutritional value of the products in which it is found.
Why is E477a valued?
Diacetylated glycerol (E477a) is valued in the food industry for its ability to stabilize emulsions and improve the consistency of products. As a result, it is widely used in products requiring long-term stability, texture and uniformity. Its stability under various temperature conditions and versatility in applications make it an indispensable ingredient in many manufacturing processes.
