Key Questions Answered
When potatoes are cut, internal compounds and starch come into contact with oxygen and begin to oxidize, changing the color from white to brown or black. This surface discoloration is a natural chemical process and does not necessarily mean the potatoes have gone bad or are unsafe to eat.
Placing cut potatoes in a bowl of cold water mixed with the juice of one or two lemons prevents rapid discoloration. The citric acid present in the lemon slows down the oxidation process, while the water blocks direct exposure to air.
If you do not have lemons, you can simply store cut potatoes submerged in cold water to reduce air exposure and slow down the discoloration process. For longer storage, place the water container in the refrigerator to keep the potatoes fresh.
