Abstract

The Amazon region, while rich in biodiversity, experiences low socio-economic development. One promising solution involves using Amazon oilseeds, which offer high nutritional value and industrial potential. However, traditional extraction methods have limitations, such as high energy use, solvent consumption, and low yields. This study optimized the extraction of Brazil nut oil (BNO) and Tucumã-do-Amazonas oil (TAO) using Ultra turrax-assisted extraction (UTAE), comparing it with conventional and non-conventional methods. Using the Plackett-Burman design, only extraction time and solvent/solid ratio were significant factors. Optimizing these variables through response surface methodology achieved high yields: 64.6% for BNO and 61.1% for TAO, outperforming Soxhlet and compressed propane extraction (CPE) by up to 43.4%. UTAE produced comparable oleic acid levels in BNO (37.0 - 37.8%) and TAO (66.1 - 68.2%). Additionally, the total phenolic content was higher in both CPE (7.87 ± 0.77 and 26.71 ± 0.63 mg GAE.100 g⁻¹) and UTAE (4.57 ± 1.00 and 19.63 ± 1.68 mg GAE.100 g⁻¹) compared to Soxhlet (1.25 ± 0.37 and 10.97 ± 1.92 mg GAE.100 g⁻¹) for BNO and TAO, respectively. These results highlight UTAE's efficiency for oil extraction.

亚马逊油的超萃取：优化以及与索氏提取和压缩丙烷提取的比较

亚马逊地区虽然生物多样性丰富，但社会经济发展水平较低。一个很有前景的解决方案是利用亚马逊油籽，这些油籽具有很高的营养价值和工业潜力。然而，传统的萃取方法有其局限性，如能源消耗高、溶剂消耗大、产量低等。本研究利用超滤辅助萃取（UTAE）优化了巴西坚果油（BNO）和图库曼-多-亚马逊油（TAO）的萃取，并将其与传统和非常规方法进行了比较。采用普拉克特-伯曼设计法，只有萃取时间和溶剂/固体比率是重要因素。通过响应面方法对这些变量进行优化，获得了较高的产量：BNO 和 TAO 的产率分别为 64.6% 和 61.1%，比索氏萃取法和压缩丙烷萃取法（CPE）高出 43.4%。UTAE在BNO（37.0 - 37.8%）和TAO（66.1 - 68.2%）中产生的油酸水平相当。此外，CPE（7.87 ± 0.77 和 26.71 ± 0.63 mg GAE.100 g-1）和UTAE（4.57 ± 1.00 和 19.63 ± 1.68 mg GAE.100 g-1）中的总酚含量均高于索氏提取（1.25 ± 0.37 和 10.97 ± 1.92 mg GAE.100 g-1）中的 BNO 和 TAO。这些结果凸显了UTAE的榨油效率。
