A method of producing edible oils with high quality by water

Abstract

The concern about environment, health, and cost has been a trigger for great interests of developing the aqueous method to process oil seeds. Here we indicate a method of processing oil seeds by using a small amount of water, which has a higher recovery rate of oils as compared with high pressure pressing and solvent extraction in term of producing First or Second Class edible oils. The method utilizes all the kernels of oil seeds and does not produce waste water or other wastes. This breakthrough indicates the strong potential of replacing solvent extraction or high pressure pressing for oilseed processing by the aqueous method. Practical applications The findings of this study should be useful for guiding the future development of research and practice of oilseeds processing. The experimental method described in this paper can be a good basis of designing and establishing brand-new commercial plants of processing oilseeds (including the design and manufacture of relevant equipment) on a large scale.
