Storage and fresh-keeping methods of Zizania caduciflora

Zizania caduciflora is a common melon vegetable, which has a large market in China, and its planting area is also extensive. However, the storability of Zizania caduciflora is relatively low, if it is not stored properly, it can easily lead to discoloration, water loss, hollow and other bad phenomena. Therefore, we also need to pay attention to the storage and preservation of Zizania caduciflora after harvest. So the editor today brings you the method of storage and preservation of Zizania caduciflora. Let's take a look at it.

1. Stacking method

After entering the harvest period, the temperature of Zizania caduciflora planted in autumn has gradually dropped to about 20 degrees. Therefore, under the condition of suitable temperature, we can store it simply on the spot after harvest. First of all, choose a relatively cool place, spread the film on the ground, and then stack the Zizania caduciflora neatly on the film. The stacking height is controlled at about 50cm, and then covered with a layer of straw on top of Zizania caduciflora. Then properly watered to maintain humidity, so stored, then it can be kept fresh for a week or so. If you flatten the base of Zizania caduciflora and apply some alum, you can pile it up for about 12 days and wash off the alum before transportation.

2. Cold storage method

The stem of Zizania caduciflora is wrapped by its leaves, and it can be harvested when we find that the waist-shaped and stout stem is formed at the eyes of Zizania caduciflora. When harvesting, we should pay attention to the method before we can use the cold storage method for storage. When harvesting Zizania caduciflora, we should pay attention to keep about 2-3 leaf sheaths, and put them in a zero-degree freezer after harvest. In this way, it can be kept fresh for at least 18 days and up to 60 days at most. You can also remove the shell and put it in a plastic bag after harvest, and the fresh-keeping effect will be better.

3. Immersion method

After harvesting Zizania caduciflora, shell it and put it in a container with clean water. Put an appropriate amount of ice in the container to reduce its temperature, and then put some heavy objects on Zizania caduciflora to prevent it from floating. Let Zizania caduciflora sink to the bottom of the water, and then the water should be changed frequently during storage to improve the water quality so as to avoid the deterioration of water quality during storage and the breeding of germs, resulting in disease. Similarly, we can also soak in alum water with a proportion of about 1.5%. However, the water should be changed frequently during soaking, and the foam should be removed, ice added, and the storage environment adjusted.

4. Transportation and storage

Zizania caduciflora must be transported with a shell when it is transported. After arriving at the destination, the sheath shell of Zizania caduciflora is removed and then graded. Before packing and transportation, it is necessary to pick out damaged, injured, diseases and insect pests and other bad Zizania caduciflora. Then every 20 jin of Zizania caduciflora is harvested and ready to go on the market, neatly arranged and packed in plastic bags. Tie it tightly, improve its firmness, and then put it on the transport vehicle. After putting, cover the bag with a layer of oilcloth to improve its moisturizing ability, it is best to reach the market within 3 days to avoid deterioration of Zizania latifolia.

The above is a brief introduction to the storage and preservation methods of Zizania caduciflora. The storage and preservation of Zizania caduciflora is very important, if it is not stored properly, it will seriously affect its planting efficiency, so we must pay more attention to it!
