Abstract: PURPOSE:Soybeans are treated with ehtanol at low temperatures to give a fraction of less denaturalization and of high protein content in high yield. CONSTITUTION:Preferably seed skin is roughly removed and then, the flake of raw soybean is treated with ethanol of 60-80vol%, preferably 65-75vol% concentration at 5-30 deg.C, preferably 10-20 deg.C to extract carbohydrates and phospholipids in the soybeans. The resultant soybeans are further treated with an organic solvent of 95-100vol% concentration such as ethanol, hexane or acetone at 40-100 deg.C and the solvent is removed. The residue is crushed so that more than 80wt% becomes less than 30mum particle sizes and fractionated to collect the fraction with particle sizes of larger than 4mum.
