Pomegranates should be stored at a temperature between 2°C and 3°C, with a maximum limit of 5°C. The ideal relative humidity for storage is 85% to 90%. Farmers have developed several traditional methods to keep fresh pomegranates for extended periods. Here are some effective techniques:
1. **Indoor Stacking Method**: Choose a cool, moist, and well-ventilated room. Lay down a layer of fresh grass or sweet potato vines about 10 cm thick on the floor. Place the pomegranates stem-side down in layers, alternating the direction of the stems as you stack them. Keep the height between 40 cm and 60 cm, then cover the pile with more grass or leaves. Adjust the covering based on temperature changes. This method can preserve pomegranates for up to 70 to 100 days.
2. **Well Pit Storage**: Select a dry and elevated area to dig a well with a diameter of 80–100 cm and a depth of 100–200 cm. Make small ventilation holes around the pit depending on the amount of fruit to be stored. Place a 10 cm layer of sand at the bottom, then stack 4–5 layers of pomegranates. Cover the well and leave a small opening for air circulation. Regular checks are necessary. This technique allows pomegranates to be stored until the end of March the following year.
3. **Container Storage**: Use clean, oil-free containers such as jars, cans, or large pots. Line the bottom with a 5 cm thick layer of wet sand and insert a grass or bamboo tube in the center for ventilation. Fill the container with pomegranates and seal it tightly. A plastic film can be placed over the sand to maintain moisture. This method is best suited for small-scale storage.
4. **Plastic Bag Storage**: Non-toxic plastic bags with a thickness of 0.04–0.07 mm, measuring 50 cm in diameter and 80 cm in height, are used. These bags are placed inside fruit baskets or boxes lined with protective pouches. The pomegranates are treated with a preservative before being packed, with each bag containing about 25 kg. During the initial storage period, the bags are folded and pressed to remove air. After one month, they are sealed and kept at room temperature. After 3–4 months, the quality of the fruit remains above 90%.
These methods not only help maintain the freshness and quality of pomegranates but also reduce post-harvest losses. Choosing the right storage technique depends on available resources, climate conditions, and the quantity of pomegranates to be preserved. Whether using simple indoor stacking or more advanced plastic bag methods, proper care ensures that the fruits remain marketable for longer periods.
