  1. Hi,

    Does anyone here know how long you can keep shredded potatoes in cold water before they start to
    oxidize? Thanks!

    Several hours if that are rinsed of the surface starch and then kept in lightly acidulated water.

    About 20 minutes if the water is salted, then they turn grayish but are still good for latkes.

    If you add some fresh lemon juice, the keeping time is greatly extended.

    By which Dimitri means to toss in a bit of lemon juice or some such. 🙂

    ...because polyphenol oxidase is inhibited at low pH.

    June, you know much more about the chemical action than I do. I just know it works. <G> My mom and
    grandmother always did it...potatoes, turnips, apples, peaches, etc. If I don't have a lemon on
    hand, I use Fruit-Fresh®, even on the vegetables.
