Assuming you are referring to the oxidation process once peeled potatoes have hit the air. After you peel potatoes, you should either use them as quickly as possible, or better yet, put them in a bowl covered with cold water. This will allow you time to prevent them being oxidized by oxygen.
Yes of course it is ok if eaten within two hours, though they don't look very pretty do they? - You could also try if they were peeled and still whole, to grate the potato more to bring back the normal color of the potato and of course, have that bowl of water available to dunk it in while you attack the rest of your browned potatoes.
I'm assuming you're asking how to keep the potatoes from turning brown once they've been cut, but haven't been cooked. I did a science experiment, and i found out that the best way you can prevent potatoes from browning the longest is to dip them in either citric acid or lemon juice, most effective would be undiluted, just pure.
Opinions and myths abound on this one! After looking at some trusted sites, the story seems to be that it's probably not a problem unless you plan on eating around ten pounds; but you'll probably want to cut out the green parts anyway. Here are three trusted sites -- the last one disagreeing with the first two.
Good Housekeeping ( http://www.goodhousekeeping.com/food/cooking/ask-susan-green-potatoes-1007 ) says it's not a big deal -- you'd never eat enough to worry about.
Kansas State University ( http://www.k-state.edu/media/WEB/News/NewsReleases/greenpotatoes101404.html ) The plant pathologist interviewed never saw a person develope a reaction -- you would get a bellyache before ra reaction. Besides, you can simply cut the green part out anyway.
Cooperative Extension ( http://www.extension.org/faq/4200 ) This one recommends " To be safe, it is best to not eat green potatoes."
No.
Bacteria might have had the chance to start growing on the surface of the potato.
No they are not good.But when you peel them put them in a bowl of cold water and they will keep longer.
no they will not turn brown
is it safe to eat potatoe with brown veins inside
Your pot is dirty
Yes it should. Potatoes turn brown when exposed to air. Covering them with any liquid should keep them from turning brown.
its just looks funny
Bananas, apples, pears, strawberries, celery, avocado, and potatoes all turn brown if left out for long enough.
No they aren't supposed to turn brown they are supposed to stay green.
Red potatoes have some nutrients in their skin. They turn into sugar just like regular potatoes, however. Potatoes are not complex carbohydrates.
