| Seabuckthorn fruit oil was processed by molecular distillation then the removal effect of phthalic acid esters（PAEs） and benzo(a)pyrene(B(a)P）,and lose of VE, α-tocopherol, carotenoids and β-carotene were studied. The results showed that under the conditions of distillation temperature 180?℃，rate of feed 1 mL/min，knifing speed 300 r/min and system vacuum degree 0.1 Pa, the DBP and DEHP residues were under the national standard detection limit(0.1 mg/kg), which was far more below the national standard limits(DBP≤0.3 mg/kg，DEHP≤0.5 mg/kg). The B(a)P residue in the oil was 1.56 μg/kg and the removal rate reached 95.4%, which was far more below the national standard limit (10 μg/kg). The acid value reduced from 14.58 mgKOH/g to 0.52 mgKOH/g. The contents of VE and α-tocopherol after molecular distillation were 72.91 mg/100 g and 67.65 mg/100 g respectively, and the lose rates were 65.2% and 59.2% respectively. The contents of carotenoids and β-carotene reduced to 196.87 mg/100 g and 525 mg/100 g correspondent with the lose rates 1.9% and 24.6%, respectively. |
