Abstract

Sequential extraction (SE) using supercritical CO₂ plus ethanol was applied to separate resin from bacuri fruit shell, where process parameters such as particle size, pressure and cosolvent use were studied. The extracts obtained were also analyzed for phenolic compounds and antioxidant capacity. The extraction results showed that SE was able to separate the resin, which is the first report described in the literature, resulting in a patent. Furthermore, the smaller particle size (0.25 mm) showed the higher extraction rates, providing good yields of lipid extracts (up to 10.09 wt%) and ethanolic extracts (up to 13.78 wt%). The extracts presented good levels of phenolic compounds, which was associated with its high antioxidant capacity. Thus, the application of SE added value to bacuri fruit shell, enabling new strands for potential applications in the food, pharmaceutical and cosmetic industries, placing this by-product in the Amazon bioeconomy scenario.

顺序萃取法是从巴枯果果壳中分离树脂的开创性方法

采用超临界二氧化碳加乙醇的顺序萃取法（SE）分离巴枯果果壳中的树脂，研究了粒度、压力和共溶剂使用等工艺参数。此外，还对提取物中的酚类化合物和抗氧化能力进行了分析。萃取结果表明，SE 能够分离树脂，这在文献中尚属首次报道，并因此获得了一项专利。此外，粒度较小（0.25 毫米）的萃取率较高，脂质萃取物（最高达 10.09 wt%）和乙醇萃取物（最高达 13.78 wt%）的产量也很高。提取物中的酚类化合物含量较高，这与其较高的抗氧化能力有关。因此，SE 的应用增加了巴西莓果壳的价值，为其在食品、制药和化妆品行业的潜在应用提供了新的渠道，使这种副产品进入了亚马逊生物经济领域。

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.
