Lowering the pH of the potato helps fight off oxidation. Just like you squeeze a lemon on sliced apples, a bit of lemon juice or white vinegar in the bowl with the potatoes will ward of gray hues.

Will peeled potatoes turn brown?

Is it normal for potatoes to be pink?

A: There are a number of causes, but the most common one people cooking at home see is a slightly pink tinge to the inside of the potatoes. These are perfectly fine to eat, although not that attractive. Basically, enzymes meet oxygen and the potatoes discolor.

What causes discoloration on the surface of a potato?

Potatoes, along with apples, pears, bananas, and peaches, contain an enzyme that, when exposed to oxygen, reacts to produce discoloration on the surface of the potato or fruit. Potato skins and fruit peels are the natural ways oxygen is blocked from reaching this enzyme. Once they are removed, oxidation begins.

Why are my russet potatoes turning brown on the inside?

The color change is simply an enzymatic reaction and has nothing to do with rot or disease. The browning occurs in all potatoes across the board, but russet varieties tend to have more of a problem than other types of potatoes because they contain less wax.
