Storage of pumpkins

Pumpkin is not unfamiliar to everyone. It is a common and nutritious ingredient. It has a sweet taste and is therefore loved by many people. Due to the high sugar content of pumpkin, if it is stored incorrectly or left for too long in normal temperature environment, pumpkin will undergo anaerobic fermentation to produce alcohol, which will cause dizziness, fatigue, vomiting, diarrhea after eating .


Storage of pumpkins



Cold storage can not only prolong the storage time of pumpkin, but also effectively inhibit the enzyme activity in the organism and kill various pathogenic microorganisms. At the same time, it can also use cold storage for off-season sales, meet consumer demand for pumpkins in different seasons, and increase the economic value of pumpkins.

Pumpkin storage method and temperature requirements:

1. Harvesting

In order to better store fresh pumpkins, it is advisable to harvest pumpkins on sunny or on cloudy days, and it is forbidden to harvest them on rainy days to prevent the accumulation of water and causing the pumpkin to rot during storage.

3. Pre-cooling

After pre-cooling, the pumpkin fresh-keeping effect will be better. The pre-cooling method can adopt the strong wind pre-cooling of the cold storage or directly enter the cold storage. The faster the cooling speed of the pumpkin, the better the storage effect.

4. Storage

The most suitable storage temperature for pumpkin cold storage is 0 ~ 3 ℃. It should be noted that the temperature in the storage is stable and the safe storage temperature should be controlled at ± 1 ℃. Storage temperature fluctuations should not exceed 2 ° C. Excessive temperature fluctuations can easily cause mold growth and decay. In addition, humidity is also an important factor affecting the moisture of vegetables and maintaining the quality and flavor of vegetables. Therefore, the suitable relative humidity of pumpkin cold storage is 80% ~ 85%. If the humidity in the warehouse is insufficient, you can humidify with a common air humidifier or a microwave air humidifier to keep the humidity in the warehouse stable.

With this method, pumpkins can be stored for about 3 to 5 months, and the nutrients in the pumpkin are not lost.
