A method for extracting soy bean oil comprising pretreatment process using ultra-high pressure

摘要

PURPOSE: A method for extracting soy bean oil is provided to remarkably improving yield and rate comparison with existing method not accompanying pretreatment process using ultra-high pressure, thereby remarkably reducing energy and time for extracting soy bean oil. CONSTITUTION: A method for extracting soy bean oil comprises: a step of pre-treating soybean oil or soybean powder by ultra-high pressure; additionally, a step of filling the pre-treated raw material into an extractor; and additionally, extracting soybean oil by putting supercritical carbon dioxide into the extractor; the supercritical carbon dioxide is carbon dioxide in the state with the temperature of 35-80 °C, the pressure of 100-900 bar, and the flow rate of 30-50 g/min.
