Does one bad apple spoil the bunch? Yes. and the same can be said for a number of fruits and vegetables. Certain fruits and vegetables release a natural plant hormone called ethylene which is a ripening agent. Other fruits and vegetables are ethylene sensitive and absorb the gas. Given enough time, fruits and vegetables will overripen and eventually rot.

Bluezone by Middleby Food Preservation continuously circulates air. As the air enters the unit, ethylene gas and other contaminants are killed using self-contained ultra violet light and ozone. Air is returned clean and fresh to prevent early ripening, extend shelf life, prevent odors and flavor transfer. Tests show that <99% of bacteria and fungi are eliminated in one hour.
