Peach is one of the most popular stone fruits, valued not only for its sweet flavor but also for its high nutritional content. The flesh of peaches is rich in proteins, sugars, vitamins (B, C, carotene), minerals (calcium, phosphorus, iron), organic acids (mainly malic and citric acid), and water.
However, unlike apples, pears, or grapes, peaches are harvested during hot summer months and are more perishable and difficult to store. Therefore, advanced storage technology is essential. Among all methods, Controlled Atmosphere (CA) cold storage is considered the most effective solution for maintaining freshness and extending the storage life of peaches.
Advantages of Peach CA Cold Storage
1.Peach Storage Comparison: Conventional Cold Storage vs. Controlled Atmosphere (CA) Storage
| Aspect | Conventional Cold Storage | Controlled Atmosphere (CA) Storage |
|---|---|---|
| Shelf Life after Removal | ~7 days | 21–28 days |
| Storage Duration | 2–4 weeks (at 0–2°C) | Up to 2 months (with ethylene absorbents at 0–2°C) |
| Freshness & Quality | Faster loss of firmness, vitamin C, and flavor | Retains firmness, sweetness, acidity, and color closer to fresh-picked |
| Decay & Pest Control | Limited; higher risk of spoilage | Reduces microbial growth and insect activity |
| Temperature Range | 0–2°C | 0–1°C (tightly controlled to avoid freezing) |
| Humidity Requirement | 85–90% | 90–95% (better moisture retention) |
| Technology | Standard refrigeration only | Low oxygen + high CO₂ + temperature & humidity control |
| Best Use Case | Short-term storage, local markets | Long-term storage, export, high-value fruit |

2. Better Freshness and Quality Retention
- Peaches stored in CA cold rooms maintain higher levels of moisture, vitamin C, sugar, acidity, firmness, color, and weight compared to conventional cold storage.
- The fruit remains crisp, juicy, and flavorful, with qualities close to freshly harvested peaches.
3. Reduced Pest and Disease Damage
- CA storage effectively inhibits pest activity and disease development, minimizing post-harvest losses and ensuring higher commercial value.

Temperature and Humidity Requirements for Peach CA Storage
- Temperature: Optimal storage temperature is 0–1°C. Since peaches have a relatively high freezing point, temperatures must be carefully controlled to avoid freezing injury, which negatively affects fruit quality.
- Relative Humidity: Ideal humidity is 90%–95%. Due to the peach’s thin skin and surface fuzz (which increases transpiration), peaches lose water easily. Maintaining proper humidity levels inside the CA storage room helps reduce water loss and prolong freshness.
For peach growers, distributors, and exporters, Controlled Atmosphere cold storage is the most advanced and reliable method for ensuring long-term freshness, extending shelf life, and preserving the natural taste and texture of peaches.
