Abstract
Abstract Shelled and skinned peanuts are treated in a substantially saturated saline solution at a temperature of about 20* to 50*C for 30 seconds to 5 minutes in order to remove tannin and odor associated with peanuts. The peanuts are then heat treated in water at a temperature of about 100* to 120*C for from 15 to 45 minutes. The peanuts thus treated then have the oil removed from them by crushing in an oil extractor. The solid of crushed peanuts is then formed into a slurry and treated in a colloid mill so that the peanuts will pass through a 400 mesh screen. The peanut slurry is then spray dried to form a free-flowing defatted peanut flour useful in many food formulations.
