Compressed -propane extraction (CPE) was applied to umari fruit ( Tul.) pulp to obtain an oil rich in high added-value components. CPE was performed at different temperatures and flow rate, which was compared to conventional extraction (Soxhlet). The oils were analyzed for global yields, fatty acid composition, β-carotene content, antioxidant activity, total phenolics content (TPC) total flavonoids (TF), and thermal behavior. The highest extraction yield (29.2 wt%) was obtained with CPE at 80 °C and 3 mL.min, being higher than that obtained by Soxhlet. The flow rate variation had a significant effect ( < 0.05) on the oil extraction yield, while the temperature had a negative effect. The umari oil obtained by CPE emerges as a rich source of oleic acid (omega-9) and β-carotene (vitamin A precursor), with potential to be applied in various industrial segments and inserted into the Amazon bioeconomy scenario.

乌玛果肉油的压缩正丙烷提取：亚马逊丰富的 β-胡萝卜素和 omega-9 来源


将压缩丙烷萃取（CPE）应用于乌玛里果（Tul.）果肉，以获得富含高附加值成分的油。 CPE 在不同温度和流速下进行，与传统萃取（索氏提取）进行比较。对油的总体产量、脂肪酸组成、β-胡萝卜素含量、抗氧化活性、总酚含量 (TPC)、总黄酮 (TF) 和热行为进行了分析。使用 CPE 在 80 °C、3 mL.min 下提取得率最高（29.2 wt%），高于索氏提取的提取率。流量变化对油提取率有显着影响（<0.05），而温度则有负面影响。通过 CPE 获得的鲜榨油是油酸（omega-9）和 β-胡萝卜素（维生素 A 前体）的丰富来源，具有应用于各个工业领域并融入亚马逊生物经济场景的潜力。
