The nutritional value of peanuts is very high, but the red skin of peanuts is often ignored, and it is often eaten after grinding off the skin. In fact, the red skin of peanuts is also called red skin, which is light and thin, but rich in ingredients. The main ingredients are cellulose, protein, fat and polyphenols, and it also contains many active ingredients beneficial to cancer prevention.
Peanut red is generally light brown or light red, and now there are colored peanuts because of different varieties. Colored peanuts are caused by the skin color variation of common peanuts. Colored peanuts can be divided into black, purple-black, white, purple-red, red-white and colored particles according to the color of kernel skin.
Dark varieties are usually rich in antioxidant polyphenols, and their contents of protein and trace elements are also higher than those of light varieties. For example, black sesame is better than white sesame, and black rice is better than white rice. Therefore, compared with light-skinned peanuts, dark-skinned peanuts have higher protein content and lower fat content.
