What is proper packaging and handling of yam?
Proper packaging and handling of yams are essential to ensure their freshness and prevent damage during transportation and storage. Here are some guidelines:
1. Selection: Choose yams that are firm, smooth, and free from blemishes or soft spots. Avoid yams with cuts or bruises.
2. Cleaning: Wash the yams thoroughly under running water to remove any dirt or debris. Use a brush if needed, but do not scrub too hard to avoid damaging the skin.
3. Drying: Allow the yams to air dry completely before packaging. Excess moisture can promote spoilage.
4. Packaging materials: Use appropriate packaging materials such as mesh bags, burlap sacks, or ventilated crates. These materials allow air circulation while protecting the yams from light exposure.
5. Size and weight: Sort and group the yams according to size and weight before packaging. This helps in efficiently packing and handling them.
6. Packaging process: Place the yams gently into the packaging material, making sure they are not overcrowded and have enough space for air circulation. Avoid dropping or tossing them as it can cause bruising or damage.
7. Storage conditions: Store yams in a cool, dark, and well-ventilated area with a temperature of around 13-15°C (55-59°F) and humidity of 85-90%. Avoid storing them near fruits or vegetables that produce ethylene gas, as it can accelerate their spoilage.
8. Handling during transportation: When transporting yams, ensure they are protected from extreme temperatures, direct sunlight, and excessive vibrations. Secure them in the vehicle to prevent any movement or physical damage.
9. Shelving: Display yams on shelves or racks in a store or market with good air circulation. Avoid stacking them too high, as it can lead to pressure and damage the yams underneath.
10. Check regularly: Regularly inspect the stored yams for any signs of spoilage, such as softness, mold, or unpleasant odors. Remove any damaged yams to prevent them from affecting others.
By following these packaging and handling practices, the yams can maintain their quality, freshness, and prolong their shelf life.
