Black Potatoes

Black Potatoes

　　Black potatoes, also known as black sweet potatoes or Black Beauty potatoes, are oval in shape with small eyes. Their skin is dark purple, glossy and shiny. The flesh is deep purple, visually appealing and rich in color. With a starch content of up to 13–15%, they have a good taste and excellent quality. Tests show that per 100 grams of black potatoes, there are 2.3 grams of protein, 0.1 grams of fat, 16.5 grams of carbohydrates, 11 milligrams of calcium, 1.2 milligrams of iron, 64 milligrams of phosphorus, 342 milligrams of potassium, 22.9 milligrams of magnesium, 0.01 milligrams of carotene, 0.1 milligrams of thiamine, 0.03 milligrams of riboflavin, and 16 milligrams of niacin. This variety is rich in anthocyanins, which not only inhibit carcinogens but also enhance immunity, delay aging, improve physical strength, and support eye health.

　　Known as “aerospace vegetables,” black potatoes with their black skin and flesh are quite rare. Recently, Song Jinhai, a farmer from Gaolizhuang Village, Qian’an City, Hebei Province, successfully planted 60 acres of “Black Beauty” potatoes on a trial basis. Moreover, his black potatoes have caught the attention of the logistics department of the Beijing Olympic Games Organizing Committee and will soon become a rare vegetable served at the Olympic dining tables.
