The non-transgenic soybean concentrated phospholipids were taken as raw materials, solvents and adsorbents were used to remove impurities and polycyclic aromatic hydrocarbons to obtain refined soybean concentrated phospholipids, supercritical CO2 extraction, thereby obtaining soybean powder phospholipids, and supercritical CO2 extraction to obtain soybean powder phospholipids. The conditions for refining soybean concentrated phospholipids are as follows: the addition amount of n-hexane was 1.5 mL/g, of attapulgite was 5%, the time was 3 h, the temperature 50℃, the stirring speed 1 500 r/min, and the impurity content of refined soybean concentrated phospholipid was 0.05%, The amount of PAHs was 2.29 μg/kg. The supercritical CO2 extraction conditions as described: extraction pressure 35 MPa, extraction temperature 50℃, and extraction time 130 min. The resulting powdered phospholipid contains 0.03% of impurities and the amount of polycyclic aromatic hydrocarbons is 1.83 μg/kg. Through actual production, the impurity content of refined soybean concentrated phospholipid was 0.08%, and the amount of polycyclic aromatic hydrocarbons 2.97 μg/kg. The supercritical CO2 extraction powder phospholipid contained 0.06% of impurities, the amount of polycyclic aromatic hydrocarbons was 2.45 μg/kg, and the HLB value could reach up to 8. © 2020, Dept. of JCCOA.
