Vegetable storage
Reasons why vegetables don't go bad in cold storage
The reason why vegetables can be stored in cold storage for a long time is related to their physiological activities.
After picking vegetables, respiration and transpiration still exist due to the loss of nutrient supply.
Vegetable storage
Vegetables will constantly consume their own nutrients and water at room temperature, and the common phenomena are "weightlessness" and "wilting". In addition, high temperature will accelerate the oxidation of enzymes and the growth of microorganisms, and ultimately affect the storage cycle of vegetables.
The low temperature environment created by refrigeration (suitable for vegetable storage temperature) can inhibit the respiration and transpiration of vegetables, and at the same time, the microbial metabolism and enzyme oxidation on the surface and inside of vegetables will also slow down in the low temperature environment.
With the help of low temperature environment, vegetables can be preserved for a long time with the lowest physiological consumption.
From the principle of vegetable preservation in cold storage, we can know that vegetable preservation is mainly related to the physiological temperature of vegetable storage, so which cold storage is suitable for different vegetable storage?
Here, General Refrigeration Company gives some suggestions on this topic:
Vegetables can be roughly divided into "high-temperature vegetables", "moderate-temperature vegetables" and "cold-resistant vegetables" according to the different cold storage temperatures. So it can be stored according to the favorite temperature of different vegetables.
The following table shows the storage temperatures of common vegetables.
Rhizome 10℃
Fruits and vegetables 7~- 12
Leaf vegetables 0~-5℃
Bean 5~ 1 1℃
Pumpkin 7~- 10℃
Mushrooms 0~-5℃
Aquatic 0~-5℃
Green pepper: the suitable cold storage temperature is 7℃ ~10℃;
Cauliflower: the suitable refrigeration temperature is1℃ ~ 2℃;
Potatoes: the suitable refrigeration temperature is-3℃ ~ 6℃;
Onion: the suitable refrigeration temperature is-1℃ ~ 0℃;
Chinese cabbage: the suitable cold storage temperature is-1℃ ~ 0℃;
Celery: the suitable cold storage temperature is-1℃ ~ 0℃;
Cucumber: the suitable refrigeration temperature is 7℃ ~10℃;
Eggplant: The suitable refrigeration temperature is 7℃ ~ 10℃.
To sum up, vegetables are suitable for cold storage.
