Peanuts are not genetically modified. Because the development of transgenic varieties is a very complicated system engineering, its cost is extremely high. At present, only sweet pepper, tomato, potato, corn and rice have been approved by China's Ministry of Agriculture to be genetically modified, but peanuts are not allowed to be genetically modified at present, so peanuts are not genetically modified.
nutritive value
Peanut contains 25% ~ 35% protein, mainly water-soluble protein and salt-soluble protein. Water-soluble protein, also called whey protein, accounts for about 10% of peanut protein, and salt-soluble protein accounts for 90% of peanut protein. Salt-soluble proteins mainly include peanut globulins and associated peanut globulins. Peanut globulin is a dimer composed of two subunits, and the accompanying peanut globulin is composed of 6 to 7 subunits.
There is little difference in nutrition between peanut protein and animal protein, and there is no cholesterol. The biological value of peanut protein is 58, and the protein titer is 1.7, which is second only to soybean protein in plant protein. Peanut fruit also contains fat, sugar, vitamin A, vitamin B6, vitamin E, vitamin K and minerals such as calcium, phosphorus and iron.
It contains 8 kinds of amino acids and unsaturated fatty acids needed by human body, including lecithin, choline, carotene, crude fiber and so on. Peanut contains choline and lecithin, which is rare in general miscellaneous grains. It can promote human metabolism, enhance memory, improve intelligence, resist aging and prolong life.
