Peanut oil

Abstract

Abstract Conventional expeller and expeller/solvent extraction processes for peanuts are compared to the nonconventional processes of direct solvent extraction, cold pressing and nonhexane solvent processes. Peanut composition, cleaning and specific extraction procedures have a major impact on finished crude oil composition, refining characteristics, final oil and meal quality and utility. Special care in raw material and process selection must be taken when using crude peanut oil for direct edible or biofuel applications. Changes in world oil prices and protein market, US peanut quota and price support program and plant breeding will have a major impact on peanut oil availability and prices in the future.
