How can sweet potatoes at home be stored for longer?

1 First of all, choose sweet potatoes, which will inevitably bump during harvesting and transportation. These broken-skinned sweet potatoes will not affect the taste, but we should pay attention to these broken-skinned sweet potatoes with black spots when storing, because such sweet potatoes are easy to rot, and will pollute other sweet potatoes and affect the storage time of sweet potatoes.

2, drying, after the sweet potato is selected, don't save it directly, but also add a drying step, in order to dry the water on its surface, so that the sweet potato is not easy to deteriorate and lasts longer. In addition, dried sweet potatoes will convert some starch into sugar under the action of amylase, so dried sweet potatoes will taste sweeter.

3, packaging, take a carton, first spread a layer of plastic paper on the bottom, and then spread a towel on it, and then put the sweet potatoes on the towel piece by piece, leaving a certain gap between the sweet potatoes, not too crowded, not stacked, so as not to get hurt. Finally, fold the towel down to cover the sweet potato and put the paper box in a cool place.

Second, the plastic bag preservation method

Wrap the dried sweet potatoes in kitchen paper one by one, then put them in plastic bags, exhaust the air from the clean plastic bags, seal their mouths and store them in a cool place.
