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. Penn Refrigeration have been experts in controlled atmosphere environments for many years. Growers in Niagara and beyond have relied on our expertise to ensure their fruit and food storage facilities operate efficiently and maintain the correct atmospheric conditions. Vegetables and fruit 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 ageing processes, thus retaining flavour and quality. Ripening is, in fact, 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. Having the proper system requires N2 generators, O2 Scrubbers and CO2 absorbers.
