Abstract

This work aims to screen the extraction of oil and bioactive compounds including carotenes and tocochromanols from oil palm fruit with subcritical propane and without using a cosolvent. The overall extraction curves of palm oil with subcritical propane were studied and compared to those extracted with supercritical carbon dioxide. Carotenes and tocochromanols were evaluated not only in the extracted oil, but also in the oil of residual fiber in order to calculate the efficiency to recover these valuable compounds. The experimental results showed that oil yield of up to 70 % could be obtained within 120 minutes with subcritical propane at 50 bar and a flow rate of 35 kg·h−1·kg−1. It was also shown that compressed propane is an excellent solvent for the extraction of oil enriched in carotenes and tocochromanols. Subcritical propane extraction can be used as an alternative process for the simultaneous recovery of these valuable minor components from palm fruit.

亚临界丙烷萃取油棕果实中的油脂、胡萝卜素和生育酚

本工作旨在筛选用亚临界丙烷在不使用共溶剂的情况下从油棕榈果实中提取油和生物活性化合物，包括胡萝卜素和生育酚。研究了亚临界丙烷萃取棕榈油的总体曲线，并与超临界二氧化碳萃取棕榈油进行了比较。不仅在提取的油中，而且在残留纤维的油中评估了胡萝卜素和生育酚，以计算回收这些有价值化合物的效率。实验结果表明，在50巴、流量为35 kg·h−1·kg−1的亚临界丙烷条件下，120分钟内可获得高达70%的油收率。研究还表明，压缩丙烷是提取富含胡萝卜素和生育酚的油的优良溶剂。亚临界丙烷萃取可作为同时从棕榈果实中回收这些有价值的次要成分的替代工艺。
