A process for extracting oil-containing nutmeat pieces to reduce the oil content by at least 25% by contacting the nutmeat pieces in an extraction vessel with liquefied hydrocarbon solvent having 3 to 4 carbon atoms under low liquefaction pressure to form a micella, separating the micella from a marc derived from the mass of nut pieces, contacting the marc with a second amount of solvent for at least two hours to form a second micella and separating the second micella from the marc and repeating this step until the oil content of the nutmeat pieces is reduced by at least 25%.
