Sweet potatoes are softened because the water in the sweet potatoes is lost. Instead of wilting because the sweet potatoes have gone bad. At this time, the nutritional content of sweet potatoes has not changed due to the loss of water, so they can still be eaten. Of course, if the sweet potato is softened due to spoilage, then the sweet potato can no longer be eaten.

Sweet potatoes are also seasonal and can be stored for more than 6 months in northern regions. However, if it is stored for too long or improperly, it will cause the loss or deterioration of nutrients, making sweet potatoes inedible.
