Photocatalytic filtration breaks down ethylene

Ethylene is a volatile organic compound that falls into the photocatalysis activated by titanium dioxide, therefore, by filtering the air of the rooms where the plant products are stored, the ethylene molecules are eliminated and the deterioration of the products is delayed.

A result that is obtained with a simple internal recirculation of air, without the use of chemicals and with a minimum amount of energy.

Prolonging the useful life of products is a primary concern for professional fresh food operators because of the obvious economic implications.

Air treatment based on photocatalytic technology is an investment with a quick return.

The process of decay of plants

Ethylene abatement from the air in storage rooms is an inexpensive (and chemical-free) method of extending the shelf life of plant products.

In fact, the phenomenon of ripening is induced by ethylene, also referred to as “ripening hormone,” and is related to the levels of plant tissue respiration and ethylene production, which increase regardless of being on the plant or not.

Ethylene is a light gas (C2H4) n contact with oxygen breaks down into carbon dioxide (C02) and water and produces heat. It can be produced by all organs of the plant, spreads easily in the tissues and disperses in the air.

With respect to their maturity, fruits are divided into two categories. Climacteric fruits are defined as those fruits that ripen even after being detached from the plant. On the other hand, those fruits which, after being detached from the plant, interrupt the ripening process are callednon-climacteric.

Ethylene is artificially added to storage rooms by those who need to speed up or restart the ripening process (common example are exotic fruit traders).

If, on the other hand, the need is to delay ripening to prolong the useful life of the products, then the opposite is the thing to do, treat the air forethylene abatement.
