    Wash potatoes or fried potatoes can be added vinegar, not only can be cleaned, but also retain the nutrition inside the potatoes. Add vinegar at the step of washing potato shreds, because potatoes are rich in polyphenols, which are easily oxidized after being cut. After being soaked in vinegar, it can inhibit the activity of oxidase and make it difficult to change color. There are also vegetables like lotus root.
