It surrounds us during our entire lives, and we breathe it in and out from our first to our last moment. Without it, there would be no life on our planet. We are talking about one of the four elements, air. The air combines gases that make up the earth’s atmosphere. Dry air is mainly composed of two gases: Nitrogen (N2) is the primary air component at 78.08 percent. At 20.92 percent, oxygen (O2) is the second most crucial component.
Furthermore, air contains noble gases (0.93 percent in total), mainly argon, as well as helium, neon, krypton and xenon. In addition, carbon dioxide (CO2) makes up 0.037 percent, and is one of the main air components due to its importance for living organisms and the climate. The air also includes methane, hydrogen, nitrous oxide (laughing gas) and carbon monoxide. In this article of Gazettely, we will tell you nine interesting things about the air that you probably don’t know.
The air is also an ingredient. The fans of molecular cuisine, where the recipes call for the use of “airs,” know this well. These are foams produced with emulsifying substances such as soy lecithin, which dilute ingredients with a very strong flavor (lemon juice, parsley, mint). Apparently, the air was invented by the guru of molecular cuisine, Ferran Adrià, when he saw carrot juice coming out of a centrifuge.
