How long can yam bean be kept?
Generally 15 days or more.
Because the water content in yam bean is less, and its texture is hard, so it is not easy to be damaged by the outside world, so the storage time is generally longer. Under normal circumstances, it is no problem to store it for half a month. If the storage method is proper, it will not go bad for a month or two. In addition, if yam bean is relatively fresh, it is generally not recommended to store it in the refrigerator, which is easy to frostbite yam bean.

How to keep yam for a long time?
Ventilation and dry preservation are the longest.
Yam bean's preservation method is very simple, basically similar to that of potatoes. As long as the storage environment is ventilated and dry, it can be preserved for a long time. If yam bean is placed in a humid place, it will easily lead to the germination of yam bean. Therefore, it is recommended to store yam bean in a cool, ventilated and dry place.

Yam bean can be cooked for a few days
1, at room temperature: yam cooked in winter can generally be preserved for about 2 days, because the temperature in winter is low, which is not conducive to the growth of bacteria, but if it is summer, it is recommended to eat it on the same day to avoid spoilage.
2, refrigerator preservation
(1) If the cooked yam bean is stored in cold storage for at most 3 days, it should not be stored for too long, because the humidity in the cold storage layer is high, it is easy to cause bacteria to grow.
(2) If the yam is cooked and stored in the frozen layer, it is no problem to keep it for about 2 months, because the frozen layer is very dry and the temperature is very low, which is not conducive to the survival of bacteria, so it is beneficial to preservation.

How to preserve yam after peeling?
1, soak and save
Yam bean is prone to oxidation and blackening after peeling. Therefore, completely soaking yam bean in water is beneficial to avoid yam bean from touching the air. In addition, yam bean soaked in water will lose some starch and mucus, so it will be crispy to eat.
2. Steamed and preserved
Cooked and preserved peeled yam bean can not only be oxidized and blackened, but also kill bacteria and prolong the preservation time of yam bean.
3. Save with lemon juice
In addition, a lemon contains vitamin C with strong antioxidant effect, so you can sprinkle lemon juice on peeled yam bean, which can also avoid the blackening of oxygen in yam bean.
3, refrigerator storage (minimum 10 degrees Celsius)
There is also the simplest way, which is to wrap the peeled yam bean in a fresh-keeping bag and seal it, put it in a fresh-keeping box, and then put it in the refrigerator, so as to isolate it from the air and avoid the growth of bacteria, and prolong the shelf life of yam bean.
five
Can yam bean be dried and preserved?
It can be dried and preserved.
If you don't pay attention to buy too much yam bean, you can wash the yam bean, slice it directly, and air it in a ventilated place with direct sunlight. Although this will lead to the loss of nutrients in yam bean, it can be preserved for a long time, at least half a year.
