Study on CA storage technology of green peppers

The objective of this study was to make preservation of fresh green pepper by controlled atmosphere ( CA) storage.With fresh green pepper as the experiment material, the preservation effect of green pepper fruit storage on oxygen and carbon dioxide concentration in atmosphere- controlled and pre- treatment for storage were studied.The main results showed that gas composition in 0²1d storage was 6% O2+ 5% CO2+ 89% N2, and 4% O2+ 2% CO2+ 94% N2 in 21⁴2d storage, could as far as possible to keep a constant temperature in the refrigerator.Composite coating before CA storage could improve the preservation effect. After 42d of storage, the weight loss of green pepper was 8.47%, aging index 18.4%, 15.7% and 52.1% lower than the control respectively. The value of the green pepper fruits was improved obviously.
