See Peanut for plant characteristics. Among edible vegetables oils, peanut oil is exceeded in world production only by soybean. World production of peanut oil, 1964-66, averaged 3,166,000 tons. In extracting the oil in the U.S., the cleaned nuts are passed through hullers or shellers to separate the kernels. The kernels, which contain 48 to 56 percent of oil, are then crushed, heated and pressed hot in hydraulic presses. The oil is used in the manufacture of margarines and shortenings, and as a salad and cooking oil. The press cake is used for cattle food.
Shelled peanuts crushed for oil annually in the U.S. averaged near 377 million pounds, 1964-66. Oil production averaged near 157 million pounds for the 3 years.
