摘要
对乌梅果（Poraqueiba sericea Tul.）果肉进行压缩正丙烷萃取（CPE），以获得富含高附加值成分的油脂。正丙烷萃取在不同的温度和流速下进行，并与传统萃取（索氏提取法）进行了比较。对油的总产量、脂肪酸组成、β-胡萝卜素含量、抗氧化活性、总酚含量（TPC）、总黄酮含量（TF）和热行为进行了分析。CPE 在 80 °C 和 3 mL.min-1 条件下的提取率最高（29.2 wt%），高于索氏提取法。流速变化对萃取率有显著影响（p < 0.05），而温度则有负面影响。通过 CPE 获得的乌玛里油含有丰富的油酸（omega-9）和 β-胡萝卜素（维生素 A 前体），具有应用于各种工业领域并融入亚马逊生物经济情景的潜力。
Compressed n-propane extraction of umari pulp oil: A rich Amazon source of β-carotene and omega-9
Compressed n-propane extraction (CPE) was applied to umari fruit (Poraqueiba sericea 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−1, being higher than that obtained by Soxhlet. The flow rate variation had a significant effect (p < 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.
期刊介绍：
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
