Controlled Atmosphere Storage

CA Cold Storage uses oxygen and carbon dioxide concentrations of about 1% to 5% for each gas in most applications. Normal room air has an O2 concentration of about 21% and CO 2 levels near 0.03%. Low O2 and high CO 2 levels slow the ripening process, stop the development of some CA Cold Storage disorders such as scald in apples, and slows the growth of decay organisms. All of these effects increase storage life of fresh produce compared with conventional refrigerated stores. These facilities are recommended for long term storage of fruits and vegetables like Apples, Pears, kiwi, cabbage etc. for up to 10 months.
