Sesame is a popular functional food in Asia. However, research on sesame seed oil cake compounds and their extraction methods is lacking. Ultrasound technology was applied to develop an efficient extraction method for this purpose. First, pilot-scale extraction from sesame oil cake was performed and optimized using response surface methodology. The extract obtained using optimized conditions (0% ethanol for 4 h at 20°C) showed the highest yield (45.1%) and inhibitory effect on reactive oxygen species (ROS; 55.1%). Compared to extracts obtained by conventional extraction methods, those obtained by ultrasound technology exhibited a higher extraction yield, greater antioxidant effect, and increased lignan content. Based on pilot-scale experiments, an industrial-scale ultrasonic extraction system was designed to extract a 2.1-ton solution at once. The extract contained sesaminol 1,2-diglucoside (4.6 mg/g) as the major component and showed 28.3% ROS inhibition activity. Our industrial ultrasound-assisted extraction method has potential application for other compounds.
芝麻是亚洲一种受欢迎的功能性食品。然而，关于芝麻籽饼化合物及其提取方法的研究还很缺乏。超声技术被应用于开发一种高效的提取方法。首先，使用响应面法对芝麻油饼进行了中试规模的提取和优化。使用优化条件（0%乙醇，20°C 下提取 4 小时）得到的提取物的产率最高（45.1%），对活性氧（ROS）的抑制作用最强（55.1%）。与传统提取方法得到的提取物相比，超声技术得到的提取物具有更高的提取产率、更强的抗氧化作用和更高的木脂素含量。基于中试实验，设计了一个工业规模的超声提取系统，可一次性提取 2.1 吨溶液。提取物中含有芝麻林酚 1,2-二葡萄糖苷（4.6mg/g）作为主要成分，对活性氧的抑制活性达到 28.3%。我们的工业超声辅助提取方法对其他化合物也具有潜在的应用价值。
