If you put potato powder in a common plastic bag and store it at room temperature, it can be stored for 3~5 days, stored in the refrigerator for about 15 days and frozen for more than 20 days.

Fresh potato flour can be stored directly in a bag, or soaked in cold water, picked up and dried for about 25 days. Potato powder can be stored for 3~4 days by putting it in cold water and changing the water every day, and the taste will not change.

Cooked potato flour should be eaten as soon as possible and should not be stored for too long. If you can't eat it all at once, you can put it in the refrigerator. Remember to wrap it with plastic wrap to avoid the smell of potato powder.

Cooked potato flour is best eaten on the same day, and it will taste bad after a day. If you can't eat so much potato flour at once, cook less.
