Sesame cake was submitted to pressurized liquid extraction (PLE) for process optimization. Then, supercritical fluid extraction (SFE), followed by optimized PLE were applied to recover the oily fraction and the polar extract, respectively. PLE samples, at optimized condition and from SFE deffated cake, showed high levels of TPC (33.15 and 31.86 mg GAE/g), DPPH (97.64 and 94.38 µmol TE/g), FRAP (46.12 and 46.69 mg TE\g), flavonoids (2.26 and 2.31mgQE/g extract), yield (13.76 and 16.25 %) and protein (56.52 and 54.08 mg BSA/g), respectively. The oily fraction presented high levels of carotenoids and essential fatty acids, while PLE extracts presented higher concentration of ferulic acid, 4-aminobenzoic acid, and quercetin compared to Soxhlet extract. Total Reduced Sugar (TRS) content suggests sesame cake as good biomass for bioethanol production. The sequential process (SFE + PLE) was efficient to recover two bioactive fractions from sesame cake, contributing to improve the value of this co-product.

使用绿色溶剂进行顺序高压萃取,从芝麻饼中回收生物活性化合物
将芝麻饼送至加压液体萃取 (PLE) 进行工艺优化。然后,应用超临界流体萃取 (SFE) 和优化的 PLE 分别回收油性部分和极性提取物。在优化条件下和来自 SFE 分解饼的 PLE 样品显示高水平的 TPC (33.15 和 31.86 mg GAE/g)、DPPH (97.64 和 94.38 μmol TE/g)、FRAP (46.12 和 46.69 mg TE\g)、黄酮类化合物 (2.26 和 2.31 mgQE/g 提取物)、产量 (13.76 和 16.25 %) 和蛋白质 (56.52 和 54.08 mg BSA/g)。与索氏萃取物相比,油性部分表现出高水平的类胡萝卜素和必需脂肪酸,而 PLE 提取物表现出更高浓度的阿魏酸、4-氨基苯甲酸和槲皮素。总还原糖 (TRS) 含量表明芝麻饼是生产生物乙醇的良好生物质。顺序工艺 (SFE + PLE) 可高效地从芝麻饼中回收两种生物活性馏分,有助于提高该副产品的价值。
