STUDY ON THE ULTRASONIC EXTRACTION OF GRAPE SEED OIL

Lili Yu

Abstract

Ultrasonic extraction of grape seed oil was studied by using single factor experiment and orthogonal method.The best technical conditions for grape seed oil extraction was obtained as follows:the extraction solvent as Petroleum ether,action time as 40 minutes,ultrasonic operation as 120 W,ratio of raw materials and solution as 0.100 g:1mL and temperature as 70 ℃.The highest extraction rate reaches 14.05 %.
