1. Features
Controlled atmosphere storage (CA) is an internationally recognized advanced preservation technology. It’s not simply low‑temperature refrigeration; rather, it involves precise control of the gas composition within the storage environment. By accurately controlling temperature, humidity, oxygen, carbon dioxide, and ethylene concentrations, this technology effectively inhibits the respiration and metabolism of fruits and vegetables, putting them into a near‑dormant state.
This process significantly reduces moisture loss and nutrient depletion, effectively delaying ripening and aging, thus perfectly preserving their original color, flavor, texture, and nutritional value for a longer period. Compared to conventional refrigeration, CA can extend shelf life by 2–3 times, making it an ideal choice for high‑quality long‑term storage.
2. Advantages
- Low-oxygen (1-5% O₂) · Slows respiration
- High humidity (90-98% RH) · Prevents dehydration
- Extends shelf life 2–3x longer vs. conventional
- CA doors prevent air leakage
- All connections gas-tight
- Blocks microbial growth & contamination
- Real-time temp/humidity/O₂/CO₂ monitoring
- Remote access & intelligent alerts
- Reduces manual checks ~70%
- 100% physical gas regulation – no chemicals
- Freon‑free, natural refrigeration
- Robust, low maintenance
