Abstract:
      The pomelo seed oil was prepared by ultrasound-assisted aqueous enzymatic extraction. The effects of enzyme dosage, pH, enzymolysis temperature, enzyme ratio, enzymolysis time on the yield of pomelo seed oil were discussed. The results showed that the optimal extraction conditions were determined as follows: enzyme dosage 2.0%(based on pomelo seed mass), pH 6, enzymolysis temperature 50?℃, ratio of cellulase to neutral protease 2∶?1, and enzymolysis time 60 min. Under these conditions, the yield of pomelo seed oil reached 33.2%. In addition, through the detection of hydroxyl free radical scavenging rate and superoxide anion free radical scavenging rate, the antioxidant activity of pomelo seed oil was compared with vitamin C and resveratrol, and the results indicated that pomelo seed oil had good antioxidant activity.
