Propane

Propane is a naturally occurring hydrocarbon gas used as a propellant (E944) in food-grade pressurised spray products, including cooking oil sprays and certain whipped food dispensers. At food-grade purity, it functions solely as a pressure source to expel the food product from the canister, with minimal transfer of the gas itself to the food. It is commonly used alongside butane (E943a) and isobutane (E943b) in propellant blends.

JECFA has not evaluated propane with a formal ADI for food additive use, as trace residue levels at food contact do not present identifiable toxicological concerns. Propane is not metabolised to harmful compounds at the exposure levels encountered in food spray products.

Propane (E944) is approved in the EU and the United States for use in food aerosol applications. Food-grade propane is subject to strict purity specifications to exclude contaminants. Consumers using cooking sprays should be aware that propellants are present alongside the oil content, though at the quantities involved there is no safety concern. The primary consideration is that cooking spray cans are pressurised and should be stored away from heat sources, which is a handling requirement rather than a food safety issue.
