Abstract

Araçaúna (Psidium myrtoides) is a native fruit from the Brazilian Atlantic Forest. It was studied for the proximate composition of its flour and sequential extraction using supercritical fluid extraction (SFE) in the first stage with CO₂ and pressurized liquid extraction (PLE) with ethanol and water in the second and third stages, respectively, at 50°C and 60°C. The proximate analysis revealed essential information about the flour regarding the content of protein, carbohydrates, lipid, ash and moisture. The sequential extraction at 60°C resulted in high yields (42.22 %). The first stage using SFE captured the volatile fraction, notably 1,4-diethylbenzene, which corresponds to 53.70 % of the total volatile compounds identified in the araçaúna. Comparing the second and third stages, the third stage with water at 50°C produced the highest levels of phenolic compounds (33.06±2.26 mg GAE/g extract), total monomeric anthocyanins (3.91±2.10 mg C3G/g extract), antioxidant activity by ORAC (415.13±13.66 µmol TE/g extract) and FRAP (747.16±18.49 µmol TE/g extract), and cyanidin-3-glucoside as the predominant compound (4.83 % w/w).

Araçaúna（山慈姑）面粉：用超临界二氧化碳和加压流体进行顺序提取

Araçaúna（Psidium myrtoides）是巴西大西洋森林中的一种本地水果。研究人员对其面粉的近似成分进行了研究，并在第一阶段使用二氧化碳进行超临界流体萃取（SFE），在第二和第三阶段分别使用乙醇和水进行加压液体萃取（PLE），萃取温度分别为 50°C 和 60°C。近似分析揭示了面粉中蛋白质、碳水化合物、脂肪、灰分和水分含量的基本信息。在 60°C 温度下进行连续提取的产量较高（42.22%）。第一阶段使用 SFE 捕获了挥发性部分，特别是 1,4-二乙基苯，占阿拉卡乌娜中已识别挥发性化合物总量的 53.70%。比较第二和第三阶段，第三阶段在 50°C 水温下产生的酚类化合物（33.06±2.26 毫克 GAE/克提取物）、单体花青素总量（3.91±2.10 毫克 C3G/克提取物）、ORAC 抗氧化活性（415.13±13.66 微摩尔 TE/克提取物）和 FRAP 抗氧化活性（747.16±18.49 微摩尔 TE/克提取物）水平最高，氰苷-3-葡萄糖苷是主要化合物（4.83 % w/w）。

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.
