Post-Harvest Physiological Challenges in Indian Jujube (Apple Ber)
Indian Jujube or Apple Ber (*Ziziphus mauritiana* - Green Apple Ber, Thai Super Ber) is a crisp tropical fruit experiencing rapid post-harvest respiration. Primary degradation issues include:
- Loss of Apple-like Crispness: Transpiration causing flesh softening, mealiness, and skin wrinkling within 5–7 days at room temperature.
- Skin Pitting & Browning: Ethylene accumulation causing skin brown spots and pitting decay.
- Fungal Rot (*Alternaria* & *Rhizopus*): Fruit decay around the stem cavity accelerated by surface moisture droplets.
Recommended Cold-Chain & Storage Protocol
| Parameter | Recommended Export Value | VAMSA Technical Impact |
|---|---|---|
| Storage & Transit Temp | 5.0°C to 7.0°C (41°F – 45°F) | Eliminates chilling injury while retarding respiration rate |
| Relative Humidity (RH) | 85% – 90% | Preserves fruit skin turgidity and crisp apple crunch |
| Target $O_2 / CO_2$ Balance | 3% – 5% $O_2$ / 5% – 8% $CO_2$ | Delays fruit skin softening & preserves vitamin C content |
| Liner Specification | VAMSA Fresh Keeper Grade FK-STD (26 × 40 in, 25µm) | Active Silver Nano ethylene conversion + anti-fog condensation barrier |
| Max Export Transit Duration | 25 – 35 Days | Enables ocean freight and long-distance road logistics |
