Study on Optimum Extraction Conditions of Orange Peels Carotenoids

Pan Siyi

Abstract

This paper compared the efficiency of ultrasonic aided-extraction with the efficiency of stirring-up extraction. The optimum conditions of ultrasonicaided extraction are established as follows:acetone:petroleum ether=2:1 (V/V), ratio of material to solvent 1:40, ultrasonic extraction at 30 ℃ for 3 times and 6min for each time with the results of less time and energy consumption and better yield.
