Whether or not the lotus root can still be eaten after it has been cut and left for some time depends on the temperature, ambient humidity, and the degree of environmental hygiene in which it has been left. Generally, it can be eaten at room temperature for about four hours, and can be kept in the fresh layer of the refrigerator for about three days and in the frozen layer for about three months.
1. Temperature: Generally about 27 degrees Celsius room temperature, lotus root cut can be kept for four hours, refrigerator fresh layer can be retained for about 3 days, frozen layer for about 3 months. The higher the temperature, the easier it is to deteriorate, but temperatures above 70 degrees Celsius are easy to inhibit the propagation of bacteria.
2. Environmental humidity: the higher the environmental humidity, the easier it is for the lotus root to deteriorate.
3. Degree of environmental hygiene: A high level of bacteria in the environment will further shorten the preservation time.
Vegetables such as lotus root are recommended to be consumed as early as possible after cutting to avoid spoilage, while many components in the vegetable will be oxidized in oxygen, thus reducing the nutritional value.
