Controlled Atmosphere (CA) Storage
Vegetables and fruits respire; they take in oxygen (O2) and give off carbon dioxide (CO2). The storage of fruit and vegetables in a gas-tight environment allows the oxygen level in the air to be lowered and the level of CO2 to increase. Long-term storage of vegetables and fruit actually involves inhibiting the ripening and aging processes, thus retaining flavor and quality. Ripening has, in fact, been postponed. This occurs as a result of modifying the gas conditions in the cool cell so that the respiration of fruit and vegetables is reduced.
Controlled Atmosphere (CA) is a storage technique whereby the level of oxygen is reduced and CO2 is increased. Quality and the freshness of fruit and vegetables are retained under Controlled Atmosphere conditions without the use of any chemicals. Under CA conditions, many products can be stored for 2 to 4 times longer than usual.
