What is CA Storage?
CA storage modifies the entire atmosphere of the storage room according to the fruit requirements i.e., O2, CO2, ethylene levels, humidity, temperature, etc. Because of technology advancements and logistic strategies, the controlled atmosphere storage of perishable items has become an important stage in the distribution between manufacturers/processors and retail locations.
The CA storage ensures the increased availability and improved quality of high-value perishable fruits and vegetables for both export and local sale, which would otherwise perish or deteriorate.

About The Technology
CA Store Technology
CA 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 CO2 levels near 0.03%. Low O2 and high CO2 levels slow the ripening process, stop the development of some storage disorders such as scald in apples, and slows the growth of decay organisms.
All of these effects increase the 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, Kinnow, and Cabbage, etc. for up to 10 months.
