Hexane:acetone:ethanol (2:1:1 v/v/v) including 0.05% (w/v) butylated hydroxyl toluene (BHT) was used as a solvent, with 1:35 w/v solid liquid ratio at 15±5°C. Ultrasonic power (50, 65, 90W) was applied in UAE for 1-30 min. Conventional organic solvent extraction (COSE) was applied under the same solvent and temperature conditions for 10-40 min. UAE was more effective and required a shorter time than COSE. Maximum lycopene and β-carotene yields were obtained using 90W ultrasonic power for 30 and 15 min, respectively.Review
