Pesticide is absorbed not just into a potato's skin but its flesh as well; scrubbing or peeling can make a difference, but won't remove all the pesticides. On that somber note: To scrub potatoes, rinse them under cool water then brush them with a vegetable brush if you want to be extra thorough.
Rinsing potatoes helps remove excess starch, so it is recommended to rinse the potatoes before cooking. To ensure even more starch is out of the way, it's recommended that they even be quickly rinsed after boiling. We recommend using hot water for rinsing after boiling and cold water prior to boiling.
Eat the skin to capture all the russet potatoes nutrition. The potato skin has more nutrients than the interior of the potato. It has lots of fiber, about half of a medium potato's fiber is from the skin.
The same goes for your spuds: Potato skins contain half the fiber—an essential carb that helps keep you full—and a whole lot more calcium and iron than just the starchy vegetable itself, Brown notes.
However, once you cut them, you break some of these cells. This releases some of the inner ingredients. By rinsing (as well as soaking) you remove these newly freed components from the potato. This prevents them from possibly interfering with your potato frying process.
The Food and Drug Administration advises you wash potatoes before you eat them. Potatoes grow in the ground, and carry not only dirt but also bacteria to the grocery store and later, your table. Pesticides also remain on potato skin; even organic potatoes carry some degree of contaminants.
Glycoalkaloids occur naturally in potatoes and are toxic to humans at high levels. Glycoalkaloids are concentrated in the peel and prolonged exposure of tubers to light will stimulate the formation of glycoalkaloids near the surface of the potato tuber. Glycoalkaloids are not broken down by cooking or frying.
Wash the potato by running it under lukewarm tap water to remove dirt and germs. Use a vegetable brush to scrub the potato to loosen any dirt that is stuck to the jacket of the potato. Optional: If soaking, place the potatoes in a clean bowl filled with lukewarm tap water for 20 minutes or less.
Don't Wash Before Storing
Since potatoes are grown underground, they often have dirt on their skins. While it may be tempting to rinse off the dirt before storing, they will last longer if you keep them dry. This is because washing adds moisture, which promotes the growth of fungus and bacteria.
The Federal Institute for Potato Research recommends that you do not eat potatoes with their skins on. The skin contains harmful solanine.
When fried, however, the content of the chemical more than doubled to 44 milligrams per 100 grams. According to Mondy's report, the high glycoalkaloid content of fried potato peels could cause possible toxicity. “These findings are important because fried potato peels have become a popular snack.”
Potatoes are 80 percent water, so softness is usually just a sign of dehydration. But if they're extremely mushy or shriveled, do not pass go. Likewise, small sprouts can be removed with a vegetable peeler or knife. Long or large sprouts are a sign that the potato is probably past its prime and should be tossed.
Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.
Why use salt water for soaking potatoes? There's moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.) So, if you put the potatoes in a salt water bath, that will help draw out some of their moisture, resulting in crispier fries.
All potatoes are flumed in water as they go down the sorting lines and washed before being packed into cartons or bags, it doesn't hurt to rinse them one more time to get any surface dirt or sand off the potatoes you receive.
On the other hand, potato skin samples were found to contain the highest levels of DDT and its derivatives, lindane and HCB. Peeling was necessary to remove the greatest amount of pesticides in the skin.
Putting potatoes in your socks cannot cure a cold or other ailments. There's no medical research that shows that it works. Eating potatoes, however, may help boost your immune system and help you beat a cold or flu. Bake, steam, or boil potatoes in their skins for the most nutrition.
Don't store potatoes in the fridge.
Raw potatoes have lots of starches, and the cold temperatures can turn the starches into sugars. This can make your potatoes turn sweeter and darker during cooking.
