This novel study reports the intensification of oil yield from kokum seeds through an energy-efficient oil extraction using the ultrasonication method. To maximize the kokum oil recovery, the ultrasonication process parameters were optimized using response surface methodology based on the Box-Behnken design. The effects of sonication time (S_t; 10–30 min), extraction temperature (E_T; 35–45 °C), ultrasonic power (U_p; 80–120 W), and solvent-kokum seed powder (sksp) ratio (30–50 mL/g) on the kokum oil yield were examined. The optimal extraction conditions were S_t=20 min; E_T= 40 °C; U_p=100 W; and sksp ratio=40 mL/g yielding 62.43 % of kokum oil. The Soxhlet extraction method yields 46 % kokum oil at an extraction temperature of 60 °C after 24 h as reported in the literature. In contrast, the ultrasonic extraction produced a 16.43 % higher kokum oil yield (i.e., 62.43 %) than Soxhlet extraction even at a reduced S_t=20 min and E_T= 40 °C. Therefore, in recovering the kokum seed oil, the ultrasonic extraction was more efficient than the Soxhlet extraction method and also this research lays the groundwork and emphasizes the necessity of investigating kokum oil's possible use as a feedstock for the manufacturing of food-grade lubricants.

这项新颖的研究报告了通过使用超声波方法进行节能油提取，可提高kokum 种子的油产量。为了最大限度地提高kokum 油回收率，使用基于 Box-Behnken 设计的响应面方法优化了超声处理工艺参数。超声处理时间（ St _； 10-30分钟）、提取温度（ET；35-45°C）、超声功率（Up ； _80-120W）和溶剂-果仁_种子粉（sksp）比例的影响(30–50 mL/g) 对kokum 油产量进行了检查。最佳提取条件为St ₌ 20 min；E _T = 40℃；Up =100W _；sksp比=40mL/g，产率62.43%的kokum油。如文献报道，索氏提取法在提取温度 60 °C 下 24 小时后可得 46% 的果油。相比之下，即使在降低的S _t = 20 分钟和E _T = 40 °C下，超声波提取的果仁油收率也比索氏提取高 16.43 %（即 62.43 %）。因此，在回收果仁籽油时，超声波提取比索氏提取法更有效，而且本研究奠定了基础，并强调了研究果仁油作为生产食品级润滑剂的原料的必要性。
