Chengkou Black Potatoes

　　The black potato has a dark-colored skin and purplish-black flesh. The tubers are oblong in shape, with a starch content of about 13–15%. In addition to containing various carbohydrates, vitamins, enzymes, and starch nutrients common to regular potatoes, it is also rich in trace elements such as iodine and selenium. It particularly contains anthocyanins and anthocyanidins, making this vegetable a natural health product that helps combat aging, enhances the body’s resilience, and improves overall physical well-being. Extracts of anthocyanins can be used in medications that enhance eyesight and protect eye health.

　　　　Black potatoes can not only replace regular potatoes for fresh consumption, frying, stewing, pan-frying, deep-frying, or boiling, but their unique color also offers greater potential in food processing. They can be used to make convenience foods, snack foods, and fast foods, such as specialty potato chips, French fries, and composite nutritional mashed potatoes.
