Matters needing attention in sweet potato preservation
1, lighting
Sweet potato is a plant that likes sunshine and can grow well in sunny places. Similarly, one of the conditions for sweet potato germination is sunshine. Therefore, when we preserve sweet potatoes, if we want to avoid their long buds, we should pay attention to avoiding sunlight and choose a dark environment or cloth with shading effect to cover them.
2. Temperature
Preserving sweet potatoes requires proper temperature. Although sweet potato is harvested in autumn, it is a kind of food that likes temperature and is not resistant to freezing. Frostbite occurs below 0℃, and it is easy to germinate above 15℃. Therefore, the suitable storage temperature of sweet potato should be controlled between 0 ~ 65438 05℃.
3. Humidity
Humidity has a great influence on the preservation of sweet potatoes. First of all, sweet potatoes germinate easily in a humid environment. In addition, in a humid environment, sweet potatoes are prone to mildew and decay to produce toxins. Therefore, sweet potatoes should be kept dry during storage. In addition, the sweet potato itself will breathe to produce moisture, so we should pay attention to keep the surface of the sweet potato dry. We can wrap it in newspaper or sprinkle some absorbent sand and sawdust to keep it dry.
