Ethylene, and ethylene containing mixtures (such as Banana Gas) are specialty gases which are commonly used to initiate the de-greening or ripening of fruits and vegetables. Typically this process is conducted in "controlled atmosphere" ripening rooms where the temperature and humidity is controlled. The pressure and flowrate of the ripening gas must also be properly controlled for the process to be both safe and effective.
