Food Additives: Glazing Agents and Propellants

food additives: glazing agents and propellantsGlazing Agents

Icing agents (also called coating agents), applied to the surface of food to make them look shiny or coated with a protective layer, such as pastries, fruit and baked goods. The most common icing agents are: beeswax (E901), carnauba wax (E903) and fatty acids (E570).

Propellants

The pressurized aerosol containers are used to manage fluid food in liquid, foam or spray. The use of propellants provides the necessary pressure to expel the food out of the aerosol container. The most common propellants are nitrogen (E941), nitrous oxide (E942) and carbon dioxide (E290).

These propellants are used to dispense foam or aerosol products such as whipped cream, cheese and mustard. This is due to nitrous oxide and carbon dioxide tend to dissolve in the fluid and expand the food out of the container, causing the formation of an aerosol or foam. Nitrogen does not have these properties and therefore is used to dispense food that requires a liquid form, such as oils and syrups.
