Peanut Is One of Popular Oil Crops
Peanut is an important shelled oil plant with high oil content. The kernel rate of peanut is 65%~75%, while the kernel contains 40%~51% oil and 25% ~ 31% proteins (a higher proportion than any in any true nut). Peanuts are rich in nutrients, providing over 30 essential nutrients. Peanut is a good source of niacin, folate, fiber, magnesium, vitamin E, manganese and phosphorus, naturally free of trans-fats and sodium. Peanuts are known by many other local names such as earthnuts, ground nuts, monkey nuts, goober peas and pig nuts. Despite its name and appearance, the peanut is not a nut, but rather a legume.
