The peanut, while grown in tropical and subtropical regions throughout the world, is native to the Western Hemisphere. It probably originated in South America and spread throughout the New World as Spanish explorers discovered the peanut’s versatility. When the Spaniards returned to Europe, peanuts went with them. Later, traders were responsible for spreading peanuts to Asia and Africa. The peanut made its way back to North America on sailing ships in the 1700’s. Although there were some commercial peanut farms in the U.S. during the 1700’s and 1800’s, peanuts were not grown extensively. This lack of interest in peanut farming is attributed to the fact that the peanut was regarded as food for the poor and because growing and harvesting techniques were slow and difficult. Until the Civil War, the peanut remained basically a regional food associated with the southern U.S.
After the Civil War, the demand for peanuts increased rapidly. By the end of the nineteenth century, the development of equipment for production, harvesting and shelling peanuts, as well as processing techniques, contributed to the expansion of the peanut industry. The new twentieth century labor-saving equipment resulted in a rapid demand for peanut oil, roasted and salted peanuts, peanut butter and confections.
