METHOD FOR SUPERCRITICAL FLUID EXTRACTION OF EDIBLE OILS WITH HIGH CONTENT OF SELENIUM

摘要

From a kind of for having the method for the extracting edible oil of the selenium of a high-content with 2. of the cereal for using supercritical carbon dioxide5 times are arranged to increase extraction efficiency and produce edible oil, contain higher than the conventional method 5.1 selenium content. It is with the extraction feature of the edible oil of the selenium of a high-content, it uses supercritical carbon dioxide as a solvent. Edible oil is sesame oil, perilla oil, peanut oil, rice bran oil, corn oil, rape oil, soya-bean oil and wheat germ oil. The raw material of edible oil has 0.1 to 5.0% water content. During extraction, by moisture weight 0.01 to 1.0% is supplied to supercritical carbon dioxide.
