Olive pomace has high economic potential and the supercritical technology for extraction produces oil with potential use in the food and biofuels industries. The remaining solid can be used to obtain fermentable sugars from the hydrolysis. The present work aims to evaluate the effect of supercritical fluid extraction (SFE) of pomace olive oil at 60 and 40 °C and 18 and 22 MPa on oil yield and composition. Furthermore, use the remaining solid of SFE to obtain fermentable sugars from enzymatic hydrolysis. Kinetic curves were obtained for SFE, with the best oil yields 19.36 ± 2.43 wt% obtained at 40 °C / 22 MPa. The antioxidant activity was better for (60 °C / 22 MPa) presenting 137.87 ± 1.04 µmol TEAC / g am. dry. The highest yield of fermentable sugar (Y) was 41.02 ± 4.79 g defatted olive pomace (DOP) for 26 Filter Paper Unit (FPU) / 1% solid loading (CS).

使用连续超临界流体萃取和酶水解从橄榄果渣中获取油和可发酵糖

橄榄果渣具有很高的经济潜力，超临界提取技术生产的油有可能用于食品和生物燃料行业。剩余的固体可用于通过水解获得可发酵糖。本工作旨在评估在 60 和 40 °C、18 和 22 MPa 下超临界流体萃取 (SFE) 果渣橄榄油对油产量和成分的影响。此外，利用SFE的剩余固体通过酶水解获得可发酵糖。获得了 SFE 的动力学曲线，在 40 °C / 22 MPa 下获得的最佳油收率为 19.36 ± 2.43 wt%。 (60 °C / 22 MPa) 的抗氧化活性更好，为 137.87 ± 1.04 µmol TEAC / g am。干燥。对于 26 滤纸单位 (FPU)/1% 固体负载 (CS)，可发酵糖 (Y) 的最高产率为 41.02 ± 4.79 g 脱脂橄榄果渣 (DOP)。
