It's impossible to tell which potatoes will turn dark, but the discoloration does not affect flavor, texture, or nutritional value

The peeled potatoes were raw. When slicing they were exposed to air (which will cause them to quickly turn dark). One method to avoid this is to peel the potatoes, place in water covering the potatoes, remove and slice on a cutting board with a knife that is steel (some blades have iron in them and till will turn the potato dark) Once you peel your boiled potato, you may notice the potato darken in color.

BLACKENING OF COOKED POTATOES There are several reasons potatoes may discolor and blacken when cooked: 1) Cooking in aluminum or iron pots.

Potatoes are divided into three general categories based on their texture — starchy, all-purpose, and waxy Why Potatoes Turn Gray 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.

The black spots you'll see inside the potato are actually bruises, caused by the potatoes getting bumped and jostled as they made their way from the soil to a warehouse to a retailer and eventually to your home. The spots form when a bump bruises the internal cell walls of the potato, releasing enzymes that create a dark pigment called melanin This browning is due to the oxidation of the starches in the potato. Potatoes will turn gray, or brown, and eventually, even black. A brown (or gray or black) potato is perfectly safe to eat Potatoes brown quickly when exposed to fresh air because they are jam-packed with starch. When these starches are exposed to oxygen, they undergo a process called oxidation, which leaves your potato with a grayish or brownish tint. They're 100% edible, but instantly less appetizing.
