0 °C low temperature plus plastic bag sealed packaging measures is the ideal conditions for short-term storage and transport of leeks. At present, there is no perfect cold chain system from harvesting to consumption, and it is still difficult to achieve a low temperature of 0°C. If it is a short-distance (6 to 12 hours) transportation, rapid pre-cooling after harvesting, and then using cold-car transport methods, the effect is better.
In the winter, from the south to the north, long-distance railway transports leeks, often using ice. First put the leeks in plastic bags and put them in bamboo baskets. Put some ice cubes between the center of the bamboo basket and the plastic bag. Spread a 33-cm-thick layer of ice on the bottom of the high-belt gondolas. Place two layers of vegetable baskets on top and put a layer of ice on them. Two layers of quilts are hung on the inside of the car lining and overlapped at the top with a layer of quilts. In this way, it can be transported from south to north by 7 to 10 days before the Spring Festival.
Fresh vegetable preservation and storage
The primary condition for storing and transporting leeks is low temperature. The ideal temperature condition is 0°C. To prevent the wilting of leeks, plastic film packaging is required. At higher temperatures, plastic film sealed packages sometimes suffer from gas damage, manifesting as dehydrated depressed spots at the tips of the leaves, producing odors. The prevention method is to avoid prolonged high temperatures, but also to play a few holes in the bag. According to experiments, the fresh-keeping period of leeks packed in polyethylene plastic bags with holes (8 holes with a diameter of 8 mm) was 3 days at 20°C, 10°C for 4 to 5 days, and 0°C for 11 to 12 days. The fresh-keeping period of the package sealed with no 0.025 mm thick polyethylene bags is 4 to 5 days at 20°C and 8 to 9 days at 10°C. 0°C is about 2 weeks.
