Abstract

The present study evaluated the effect of supercritical fluid extraction (SFE) assisted by cold pressing (SFEAP) on the overall yield, extraction kinetics, composition of baru seed oil and manufacturing cost (COM). The best extraction conditions were determined in extraction assays combining different pressures (150-350 bar) and temperatures (35 and 45 °C). The extraction yield by SFEAP (28.6 g oil/100 g baru seed) was approximately 31% higher than that obtained by SFE (21.9 g oil/100 g baru seed), according to the kinetic study with the best extraction conditions (350 bar and 45 °C). The extraction yield observed under this condition allowed us to obtain a lower COM for both techniques (SFE was US$ 118.32/kg baru oil and SFEAP was US$ 87.03/kg baru oil) compared to lower pressures and temperatures. The oil obtained under all extraction conditions was rich in unsaturated fatty acids and other bioactive compounds. The extraction of baru seed oil by SFEAP resulted in a higher yield and lower manufacturing cost than SFE.

摘要

本研究评估了冷压辅助超临界流体萃取（SFEAP）对 baru 籽油的总产率、萃取动力学、成分及制造成本（COM）的影响。在结合不同压力（150 - 350 巴）和温度（35 和 45 °C）的萃取试验中确定了最佳萃取条件。根据最佳萃取条件（350 巴和 45 °C）下的动力学研究，SFEAP 的萃取产率（28.6 克油/100 克 baru 籽）比 SFE 的萃取产率（21.9 克油/100 克 baru 籽）高出约 31%。与较低压力和温度相比，在此条件下观察到的萃取产率使我们能够为两种技术获得更低的 COM（SFE 为 118.32 美元/千克 baru 油，SFEAP 为 87.03 美元/千克 baru 油）。在所有萃取条件下获得的油富含不饱和脂肪酸和其他生物活性化合物。与 SFE 相比，SFEAP 萃取 baru 籽油的产率更高，制造成本更低。
