摘要

In the current study, response surface optimization of canola oil extraction assisted by 35 kHz, 800 W ultrasound waves and with the use of hexane and 3:2 hexane-isopropanol at the proportion of 3/2 as solvents was conducted. The influence of extraction temperature (35, 45, and 55A degrees C), ultrasound treatment time (30, 60, and 90 min), and solvent-to-canola (sample) ratio (5, 10, and 15 (% v/w)) on the percentage of the extracted oil and oxidative stability of the extracted oil was analyzed through Box-Behnken design. The achieved results revealed that the optimized conditions for canola oil extraction (22.39% efficiency) by hexane was 87 min ultrasound treatment at 55A degrees C and solvent-to-canola proportion of 6.39 (% v/w). On the other hand, the optimized conditions for canola oil extraction (30.66% efficiency) by hexane-isopropanol mixture were 69.5 min ultrasound treatment at 55A degrees C and solvent-to-canola ratio of 9.12 (% v/w). The obtained outcomes revealed that ultrasound waves significantly improved the extraction efficiency compared to Soxhlet extraction. The extraction efficiency was improved when hexane-isopropanol mixture was applied. In optimized condition, oxidative stability of the extracted oil has been achieved at 12.55 and 40.9 h, respectively, once hexane and hexane-isopropanol were used as solvents for extraction. Oxidative stability presented considerable enhancement with an increase in ultrasound treatment. Extracted oil with the use of mixed solvent (hexane-isopropanol) presented higher value for oxidative stability compared to the extracted oil with the use of hexane as a solvent. Comparison between the ultrasound-assisted and Soxhlet extracted oils with the use of gas chromatography presented no significant difference in their fatty acid profiles.
