Characteristics of fruit storage in plastic bags
Vegetables and fruits are stored in plastic bags, which is a scientific preservation method commonly used by people in winter. The principle is to reduce the concentration of oxygen and increase the concentration of carbon dioxide, so that the fruits and vegetables are in a dormant state and the storage period is prolonged. However, the storage time should not be too long.
Because vegetables and fruits are organic foods with high water content (60%~95%), and contain water-soluble nutrients and enzymes. Strong respiratory activity continued throughout storage. In general, for every 10°C rise, the breathing intensity doubles. Under aerobic conditions, sugars or other organic substances in fruits and vegetables are oxidized and decomposed, producing carbon dioxide and water, and releasing a large amount of cooked quantity; and release a small amount of heat.
However, the concentration of carbon dioxide cannot rise indefinitely, it can only increase by 10%, and the concentration of oxygen cannot drop by more than 5%. Otherwise, in order to obtain sufficient energy for life activities, fruits and vegetables must decompose more nutrients during hypoxia. . At the same time, the alcohol produced by hypoxic respiration remains in the fruits and vegetables, which will cause the fruits and vegetables to rot and deteriorate, so the fruits and vegetables should not be stored in plastic bags for too long.
If you want to store fruits and vegetables in plastic bags, it is best to open the plastic bag every 2 to 3 days, release carbon dioxide and heat, and then tie the mouth, which will reduce the occurrence of decay and deterioration.
