This study was organized into three experimental steps. In the first step, SFE was used for the extraction of the fatty acid-rich extract from unripe genipap. The extract with the highest yield (4.6 ± 0.1%) and total fatty acid content (16.6 mg fatty acids / g) was obtained at 30 MPa and 333 K. In the second step, the kinetic behavior of the overall extraction curves was studied, and the data were accurately modeled using the potential of the hot sphere diffusion model. Finally, SFE was coupled to low-pressure solvent extraction (LPSE) to obtain a genipin-rich extract (71 mg /g) from the defatted solid or SFE coproduct. The processes developed in this study (SFE and SFE+LPSE) were also analyzed from an economic point of view. The results showed that by integrating the processes it is possible to reduce the COM from US$ 86.83/kg to US$ 11.18/kg of product.

美洲美洲Gen中回收高附加值产品的过程集成:过程优化和经济评估

这项研究分为三个实验步骤。第一步,将SFE用于从未成熟的genipap中提取富含脂肪酸的提取物。在30 MPa和333 K的条件下获得了最高收率(4.6±0.1%)和总脂肪酸含量(16.6 mg脂肪酸/ g)的提取物。第二步,研究了总提取曲线的动力学行为,并使用热球扩散模型的潜力对数据进行精确建模。最后,将SFE与低压溶剂萃取(LPSE)耦合,从脱脂的固体或SFE副产物中获得富含京尼平的提取物(71 mg / g)。还从经济角度分析了本研究中开发的过程(SFE和SFE + LPSE)。结果表明,通过整合这些流程,可以将COM从86.83美元/千克降低到11美元。
