Abstract: An improved process is provided for treating skinned peanuts with an edible powder. In the improved process, peanuts including those peanuts which have split into halves are rotated relative to each other while associated with a substantially dry edible powder until the flat faces of half peanuts have an edible powder adhering thereto and two half peanuts become bonded together face to face to form a whole peanut. A tumbler having a drum disposed to rotate about a substantially horizontal axis and having a roughened interior surface is preferably used for rotating the peanuts.
