Propellant

Propellants are gases used in aerosol cans to push food products out. They are often compressed or liquefied gases like propane, butane, or isobutane, which are derived from petroleum or natural gas. These gases are carefully purified before use in food packaging.

Manufacturers use propellants to dispense products like cooking sprays and whipped toppings. They create a fine mist or foam, ensuring even distribution and preventing sticking. They are commonly found in cooking sprays, aerosolized cheeses, and whipped toppings.

Propellants used in food are regulated by the FDA and generally recognized as safe (GRAS) when used as intended. These gases are expelled from the food product and are not meant to be consumed. International bodies like JECFA have evaluated some of these substances. While generally considered safe, very high concentrations of inhaled propellant gases can pose health risks, but this is not relevant to typical food consumption.
