WIPO Patent Application WO/2007/077913
Kind Code:
A1
Abstract:
Disclosed is a process for production of a plant oil without producing any trans-type fatty acid as a by-product. The process comprises the steps of: (1) introducing a raw oil prepared by squeezing a plant seed into a column having activated charcoal filled therein from the upper part of the column; (2) allowing the raw oil to migrate in the column by the action of gravity toward the lower part of the column and discharging the raw oil from the column through a filter cloth placed adjacent to the bottom of the activated charcoal layer, wherein the filter cloth has a pore size of 13 to 45 μm; and (3) introducing the oil discharged from the column into an activated charcoal separator having a filter with a pore size of 3 to 7 μm to remove an oil having no activated charcoal micropowder from the separator by the action of a sucking force.
