Even the ancient Egyptians knew about the effect of ethylene on the ripening of fruit and made use of it. Today, the fruit-ripening effect of ethylene is also used in agriculture to ripen tomatoes, among other things. To speed up the ripening of these fruits and vegetables you submerge them in a mixture of 96% Nitrogen and 4% Ethylene (mass ratio). You can buy the premixed gas but it is a lot cheaper if you buy a bottle of pure Nitrogen and bottle of Ethylene and mix the gas yourself. This can easily be done with Vögtlin mass flow controllers.
