E943A – Butane
PropellantDescription
Colorless, odorless gas
Notes
Butane is a colorless, odorless gas that occurs naturally in crude oil and natural gas deposits. It's extracted during petroleum refining and natural gas processing, where it's separated from other gases and purified. You might recognize butane as the fuel used in cigarette lighters and portable camping stoves - it's the same substance, just held to much higher purity standards when used in food applications. In food production, butane serves as a propellant in aerosol products like whipped cream dispensers, cooking sprays, and spray oils. When you press the nozzle on a can of whipped cream, butane is what pushes the cream out while creating that light, fluffy texture. It quickly evaporates into the air once the product is dispensed, leaving behind only the intended food product. This is a synthetic gas extracted from fossil fuels, and it's suitable for all dietary requirements including vegan, vegetarian, and various religious dietary laws since it completely evaporates and doesn't remain in the final food product. Food-grade butane must meet strict purity standards and is considered safe by food safety authorities worldwide. The amounts used are minimal and designed to dissipate immediately upon use.
