A study on the elimination power of Airocide bioconversion systems on ethylene, mold and bad odors inside cold rooms.

The presence of harmful elements that affect stored fresh produce inside cold rooms is a well known problem to the industry. Within these harmful elements, the organic volatile compounds (named VOCs from now on) represent one of the biggest worries. VOCs existence is a consequence of the stored produce own metabolism, and mold spreads through the air in a spore form; and also the ethylene, that although we can include it within the VOCs group. This study, presents the results obtained after a few tests conducted in the SAT 9821, CFM group in Balsapintada, Murcia (Spain) utilizing the Airocide bioconversion system, in two different cold rooms filled with peppers and melons respectively.
