Peanuts are a crop that grows under the ground. When mature, the crop is turned over in the fields, exposing the entire root structure, including the shell. Each shell usually contains two, sometimes three, peanut kernels. These kernels, dried, classified by size, electronically sorted or hand picked (or both), and substantially free of foreign matter, are referred to as raw peanuts. Blanched peanuts are raw peanuts whose skin has been removed.
Raw and Blanched peanuts are primarily used in salted and savoury snacks, with large quantities also being used for peanut butter and, to a much smaller extent, food ingredients.
