Peanut kernel contains about 26% protein, which is twice that of wheat and three times that of rice, and it is easy to be used by human body, with a digestibility of about 90%. Peanut kernel is also rich in fat, with a content of about 40%, among which there are more unsaturated fatty acids.

And it contains eight kinds of amino acids necessary for human body, and the proportion is also appropriate. In addition, it contains many vitamins except vitamin C, and many mineral elements such as calcium, phosphorus and iron.

Research results of expanded data peanut

20 19 May, Fujian Agriculture and Forestry University was informed that the research result of Professor Chong Wai-kin's research team, "The genome of cultivated peanut reveals the karyotype, polyploid evolution and crop domestication of leguminous plants", was published online in the authoritative international academic journal Nature Genetics.

This study deciphered the whole genome of tetraploid cultivated peanut for the first time in the world, which indicates that China is at the international leading level in the genome research of cultivated peanut. This achievement has made a great contribution to the genetic improvement of peanut in the world, and is of great significance to the basic research of agriculture in China and even in the world.
