Comparing E941 - Nitrogen vs E943A - Butane

Overview

E941 - Nitrogen

Nitrogen (E941) is an odorless, tasteless gas used in food and drink to protect freshness and to push products out of cans. It replaces oxygen in packages and powers aerosol foams without reacting with the food. It is the same nitrogen that makes up most of the air we breathe.

E943A - Butane

Butane (E943a) is a food-grade liquefied gas used mainly as a propellant in aerosol products like whipped cream and cooking sprays. It flashes off quickly after dispensing, so only tiny amounts, if any, remain in the food under normal use. Regulators in the EU and U.S. allow its use when it meets strict purity rules.

Popular questions

  1. How many valence electrons does nitrogen have?

    Five; a nitrogen atom has 5 valence electrons (2s2 2p3).

  2. What is nitrogen fixation?

    Nitrogen fixation is the conversion of atmospheric N2 (E941) into biologically available forms like ammonia by microbes, lightning, or the industrial Haber–Bosch process.

  3. What is nitrogen used for?

    In foods, E941 is used as an inert propellant and packaging gas to displace oxygen, prevent oxidation, and extend shelf life. Liquid nitrogen is also used for rapid freezing and to create fine bubbles/creamy textures in beverages (e.g., nitro coffee or beer).

  4. Is nitrogen a greenhouse gas?

    No—diatomic nitrogen (N2, E941) is not a greenhouse gas because it does not absorb infrared radiation; nitrous oxide (N2O, E942) is.

  5. What is the nitrogen cycle?

    The nitrogen cycle is the movement of nitrogen among the atmosphere, soils, water, and living organisms. It includes fixation of N2 (E941) into reactive forms, biological uptake, and return to N2 via processes like denitrification.
