REFINED AND DEODORIZED CORN OIL SHOWING ANTIOXIDANT PROPERTIES

摘要

FIELD: food processing industry.;SUBSTANCE: functional-destination corn oil is produced by treating hydrated corn oil in helically rotating thin (0.1-0.2 mm) film at rotation speed 20 to 40 c^-1 and 60-80°C. Thus treated oil is neutralized with 5-15% excess of sodium silicate aqueous solution (200-270 g/L) at 60-80°C and neutralized oil is then separated from soap stock by settling. Neutralized oil is further washed with water in amount 5 to 15% based on the weight of oil at 80-90°C and washed oil is settled to separate water, dried, filtered, and deodorized at 160-170°C and gauge pressure 1-3 mm Hg.;EFFECT: achieved retention of a large amount of tocopherols possessing strong antioxidant properties.;3 tbl, 3 ex
