超声波及机械搅拌辅助提取橘皮类胡萝卜素比较研究

Study on Optimum Extraction Conditions of Orange Peels Carotenoids

比较超声波法和机械搅拌法辅助提取橘皮中类胡萝卜素提取率,确定了最佳提取条件为:超声法提取,丙酮:石油醚=2:1,提取时间6min,温度为30℃,提取次数为3次,料液比1:40。

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.
