Ultrasound-Assisted Aqueous Enzymatic Extraction of Oil from Perilla(Perilla frutescens L.) Seeds
In the present study the effects of ultrasonic pretreatment and the types of enzyme on oil yield were investigated.The optimum ultrasonic pretreatment parameters were found to be 250 W of ultrasonic power,30 min of ultrasonic time,and 50 ℃ of ultrasonic temperature.Five types of enzyme,Cellulase,Viscozyme L,Alcalase 2.4 L,Protex 6 L,and Protex 7 L,were evaluated for their effectiveness in releasing oil from ultrasonic pretreated perilla seeds.The highest oil yield of 81.74% was observed in cellulase treated perilla seed samples.The physicochemical properties of the control,hexane,and enzyme extracted perilla seed oils were compared.No significant(P > 0.05) differences were observed in iodine value,refractive index,unsaponifiable matter,saponification value,peroxide value,and acid value.
