Ultrasound is one of emerging technique's which is being investigated extremely on food applications and extraction process. In this study, ultrasound-assisted solvent extraction was employed to extract vegetable oil from coriander ( L.) seeds. A response surface model was applied to determine the best condition of extraction concerning the independent factors (COY % and DPPH %). In addition, ultrasound variables were the sample solvent ratio, amplitude level, temperature and time. The best condition of extraction was obtained for sample solvent ratio of 1:13 (g/mL), amplitude level of 82 (%), temperature of 45 (°C) and extraction time of 9 (min), being the maximum point of oil yield and antioxidant activity (30.74-72.05%), respectively. Fatty acid profile of oil has been shown as a rich source of petroselinic acid (C18:1)-12, making up 76% of all fatty acids. TGA analyses revealed that 82% (by weight) of oil is thermally stable up to 224 °C.
超声波是正在食品应用和提取过程中被广泛研究的新兴技术之一。在本研究中,采用超声辅助溶剂萃取法从芫荽籽中提取植物油。应用响应面模型来确定关于独立因素(COY%和DPPH%)的最佳提取条件。此外,超声变量包括样品溶剂比、振幅水平、温度和时间。对于样品溶剂比为1:13(g/mL)、振幅水平为82(%)、温度为45(°C)和提取时间为9(分钟)时获得了最佳提取条件,分别是出油率和抗氧化活性的最大值点(30.74 - 72.05%)。油的脂肪酸谱显示富含岩芹酸(C18:1)-12,占所有脂肪酸的76%。热重分析表明,82%(按重量计)的油在高达224°C时热稳定。
