A Controlled Atmosphere Cold Storage is a specialized facility designed to store apples under precisely regulated temperature, humidity, oxygen, and carbon dioxide levels. This controlled environment significantly slows down the natural ripening process and preserves apples’ freshness, flavor, and quality for several months.
While regular cold storage maintains temperature and humidity, CA cold storage adds precise control of oxygen and carbon dioxide levels. By lowering oxygen and increasing CO₂, the metabolic activity of apples slows down, keeping them fresh for a much longer duration compared to standard cold storage.
* Extends apple shelf life up to 8–10 months.
* Preserves natural taste, texture, and aroma.
* Reduces wastage due to spoilage.
* Provides flexibility to market apples off-season at better prices.
The temperature is typically maintained between 0°C to +2°C, with relative humidity levels of 90–95% to prevent dehydration and maintain crispness. Exact parameters may vary based on apple variety.
The oxygen level is reduced (usually to around 1–2%), while CO₂ levels are increased (1–5%) inside the chamber. This atmosphere slows down respiration and delays ripening without affecting fruit quality.
Yes, but the storage conditions such as temperature, humidity, and gas composition are fine-tuned depending on the apple variety (e.g., Red Delicious, Fuji, Gala, Granny Smith). Proper calibration ensures maximum freshness and shelf life.
Blue Cold designs and builds CA storages with flexible capacities, ranging from a few hundred MT to several thousand MT, depending on customer requirements.
Depending on the variety and storage conditions, apples can be preserved for 8–10 months without losing taste, juiciness, or appearance.
Absolutely. The process is completely natural and chemical-free. Controlled Atmosphere storage only modifies natural environmental conditions to slow ripening, without altering the fruit’s nutritional value or safety.
