Abstract

Peanut oil is prepd. by (1) treating the skinned peanuts in a satd. aq. salt soln., (2) heat-treating the peanuts in water at >90 degrees C, (3) heat-treating the treated peanuts under high press. with steam admission. pref. for 15-20 min. with addn. of an equiv. quantity of fresh water, for comminution to a slurry, (4) strongly stirring the slurry with addn. of water, (5) allowing it to settle for a sufficiently long time, pref. 1-2 hrs., to form 3 phases, namely oil phase, aq. phase and solid particle phase, (6) separating solid particle phase from liquid phase, which consists of oil phase and aq. phase, (7) centrifuging the liquid phae, pref. in a "sharpless" centrifuge, to separate the oil from water, (8) centrifuging the oil to remove residual solids particles, (9) purifying the oil by standard processes, (10) acidiying the water with an acid, pref. HCl, AcOH, mali and/or citric acid, to ppte. dissolved solid particles, (11) separating the solid particles from water and (12) recycling the water for high pressures heat-treatment. High quality edible oil is obtd. and oxidn. is prevented.
