Abstract:
      The removal of cholesterol from fish oil by seven activated clays（A，B，C，D，E，F，G）adsorption was investigated，and the activated clay G exhibited the highest adsorption effect. With activated clay G as adsorbent, the removal rate of cholesterol as index, the effects of adsorption temperature, adsorbent dosage and adsorption time on removal rate of cholesterol from fish oil were investigated. Based on single factor experiment, the optimal conditions were determined by orthogonal experiments as follows：vacuum condition, adsorption temperature 180℃, adsorbent dosage 7% (based on mass of fish oil) and adsorption time 45 min. Under the optimal conditions, the removal rate of cholesterol from fish oil was 72.89%.
