Ethylene Filters

 GreenKeeper is a combination of granules that can naturally create a modified atmosphere with extremely low levels of ethylene and other volatile's, designed to prolong the preservation of fruits and vegetables and considerably extend their shelf life. 


Vegetable hormone produced naturally by fruits and vegetables. It is known as the ripening hormone because it relegates  fruit ripening.

This is the only hormone which is a gas. As such, it can leave the producing tissue and accumulate in storage rooms, cartons, sea containers, and air craft pods effecting produce. 

R & D


 Our studies and tests demonstrate that GreenKeeper eliminates a significant part of the organic gases released by fruits and vegetables, as well as the odors produced by these gases.

Having a modified and clean atmosphere prevents the molds, fungus, yeast, and bacteria that may affect fruits and vegetables from forming. More specifically, fungal diseases like Anthracnose, Penicillium and Botrytis, and bacteria like Pseudomonas, require gaseous signals to develop. Eliminating these gases greatly reduces fungal and bacterial development.

The elimination of the ethylene produced by fruits and vegetables that accumulates inside closed cold stores naturally increases their maximum storage potential, prevents premature ripening, and keeps perishables fresher longer.



How Does It Work?

 GreenKeeper is made from a highly porous mineral material (phyllosilicate and aluminosilicate) and potassium permanganate, a highly oxidizing agent. This composition makes it possible to create a range of granules which, when placed in different types of filters, replacements, and sachets, harness the circulation of the air in the cold store for a physical and chemical double-absorption effect that eliminates contaminating gases, especially ethylene.

The role of the mineral is to serve as a support for the potassium permanganate, increasing its contact surface with the air.

Potassium permanganate promotes the oxidation of a large number of volatile organic compounds, always within the different formats available, without altering the organoleptic properties of fruits and vegetables. It is a natural way to preserve food and is also suitable for organic agriculture.

This clean atmosphere reduces the degenerative metabolism of fruits and vegetables as well as the release of gases, thus prolonging freshness and shelf life with Ethylene absorbent.
