    While refrigerating potatoes will extend its life, it’s not the best condition to keep potatoes in. The usual temperature inside the fridge is 32 to 40 degrees Fahrenheit – so, this is a little colder than the ideal setting. Placing potatoes inside the refrigerator will also expose it to moisture and cause its color to become dark (and unappealing when cooked). Also, the starch content in potatoes can convert into sugar while still uncooked (not good for health).
  • check-circle
    Yes, you can keep potatoes in the pantry (with normal temperature settings of 50 to 70 degrees Fahrenheit). However, if you’re living in a humid area (or if it’s summertime) the high temperature can cause early deterioration in potatoes. Remember that potatoes are 80% water, and being placed in hot/ dry places will cause its water content to evaporate quickly. The potatoes will then dry up, get rotten, or start to sprout.
  • check-circle
    It is not advisable to freeze raw potatoes.When picking potatoes from the grocery or vegetable stand, get those pieces that are unbruised. Cuts and peels on potatoes will expose them to air (and oxidation) and make the process of spoilage faster.
  • check-circle
    Avoid getting potatoes that are already starting to have sprouts. While the body and texture of the potatoes can still be firm, having sprouts is a sign that the potatoes are about to deteriorate.

    Store potatoes away from onions. These two are composed of chemicals that react against each other – and as a result, both will spoil and deteriorate quickly.
  • check-circle
    If you notice a few rotten potatoes in a batch of good potatoes, remove these quickly. Leaving spoiled potatoes with good ones will cause the deterioration of all the others.
