Store at low temperature, cool and ventilated, and soak in rice wine. 1, low-temperature preservation: put the yam in a sunny place to see the light, dry the surface moisture, then wrap it in newspaper, wrap it in a bag and put it in the refrigerator. This can prevent the epidermis from turning black and take it out when you want to eat it. 2, cool and ventilated: If there is no space in the refrigerator, it can also be placed in a cool and ventilated environment, relying on low temperature to inhibit its growth.

1, low-temperature preservation: put the yam in a sunny place to see the light, dry the surface moisture, then wrap it in newspaper, wrap it in a bag and put it in the refrigerator. This can prevent the epidermis from turning black and take it out when you want to eat it.

2. Cool and ventilated: If the refrigerator has no space for storage, it can also be stored in a cool and ventilated environment. The reason is the same, and its growth is inhibited by low temperature. In addition, if the storage place is humid and easy to germinate, it must be kept dry.

3, rice wine soaking: The main reason why yam turns black is the oxidation of the incision, so if you want to store it for a long time, you must keep the incision out of contact with the air. You can break it, soak it in rice wine at the incision, and then dry it with a hair dryer, which will promote wound healing. Then wrap it in a napkin and put it in a cool place, which can be kept for several months.
