Controlled Atmosphere System (CA)

Vegetables and fruits breathe (“respiration”); They take in oxygen (O2) and give off carbon dioxide (CO2). By storing vegetables and fruits in a gas-tight area, the oxygen level in the air is reduced and the CO2 level increases. Basically, long-term storage of fruits and vegetables can be reduced to inhibiting ripening and aging in order to preserve taste and quality. Essentially, maturation is delayed. This is achieved by complying with the gas conditions in the cold stores, so that the respiration of the fruit and vegetable is significantly retarded.

Controlled Atmosphere (CA) is a storage technique in which the oxygen level is lowered and the CO2 generally increased. The quality and freshness of vegetables and fruits are preserved under Controlled Atmosphere conditions without the use of chemicals. Many products can be stored for 2 to 4 times longer under CA conditions.
