“…Extraction with propane has been shown to have significant benefits, even when compared to extraction with CO 2 , such as higher yields, higher solubility of non-polar compounds, selectivity, as well as shorter extraction times and reduced solvent consumption (Correa, Mesomo, Pianoski, Torres, & Corazza, 2016;Hamdan, Daood, Toth-Markus, & Illés, 2008). Zanqui et al (2015) extracted flaxseed oil using n-propane as supercritical fluid under different pressures and temperatures.…”

Bioactive compounds are extracted from natural sources and they have beneficial effects on human health. Fruits and vegetables are rich in carotenoids, phenolic compounds, Vitamin C, among others. Extraction processes for these compounds depend on several factors such as the technique that is used, the raw material, and the organic solvent. Conventional techniques generally require large amounts of organic solvents, high energy expenditure, and are time consuming, which has generated interest in new technologies that are referred to as clean or green technologies. These can reduce or eliminate the use of toxic solvents, and thus preserve the natural environment and its resources. The aim of this review is to discuss recent techniques used to extract bioactive compounds from natural sources, in order to reduce the economic and ecological impact of these processes. Tecnologías verdes para la extracción de compuestos bioactivos en frutas y verduras RESUMEN Los compuestos bioactivos son extraídos de fuentes naturales y tienen efectos beneficiosos en la salud humana. Las frutas y verduras son ricas en carotenoides, compuestos fenólicos, vitamina C, así como en otras sustancias. Los procesos para extraer estos compuestos dependen de varios factores: la técnica utilizada, la materia prima y el solvente orgánico, entre otros. Además de ocupar mucho tiempo, las técnicas convencionales generalmente requieren grandes cantidades de solventes orgánicos y elevados gastos energéticos: ello ha generado interés en el uso de tecnologías nuevas, llamadas limpias o verdes. En tanto éstas pueden reducir o eliminar el uso de solventes tóxicos, permiten conservar el medio ambiente y sus recursos. El propósito de la presente revisión es examinar las técnicas empleadas recientemente para extraer compuestos bioactivos de fuentes naturales, con el fin de reducir el impacto económico y ecológico que conllevan estos procesos.

“…Propane is a good alternative to CO 2 for the extraction of vegetable oils, due to the greater solubility of lipids in this solvent, as demonstrated by Munuklu et al, Ndiaye et al, Ilic et al, and Hegel et al; it also provides extracts free of solvents and toxic waste. Thus, high yields are obtained in a shorter extraction time, with a smaller volume of solvent and lower pressures than those reported for carbon dioxide . In addition, it has been reported that vegetable oils extracted with propane demonstrate good thermal stability, with high oxidative induction times when compared with organic solvent extraction techniques and with supercritical CO 2 .…”

Macauba kernel oil (MKO) was extracted using supercritical CO 2 and compressed propane as the solvent. The influence of temperature (313-353 K for CO 2 and 303-333 K for propane) and pressure (18-22 MPa for CO 2 and 8-12 MPa for propane) on oil yield was investigated, and the results were compared with conventional extraction. A characterization of oil and defatted meal was performed. Temperature and pressure, in the evaluated range, influenced oil yield with the use of CO 2 . For propane, the oil yield was not influenced by the experimental conditions. In the evaluated experimental range, the use of propane and CO 2 provided 100 % and $93 % oil yield compared to conventional extraction, respectively. MKO showed a predominance of saturated fatty acids, among which lauric acid was the major constituent. CO 2 presented greater efficiency in the removal of phytosteroids and tocopherols from the macauba kernel, however, the oil extracted with propane presented longer oxidative stability. Defatted meals presented modified physico-chemical composition and potentiated technological characteristics due to oil removal.

“…Also, its solvent properties may be modulated by alterations in temperature and pressure conditions, as well as by adding modifiers or co-solvents for extracting a widely variety of chemicals from biomass. Additionally, many studies have been oriented to the use of pressurized hydrocarbon fluids such as propane and butane due to their high affinity for oils, waxes and greases (Correa et al, 2016;Fetzer et al, 2018;Gu et al, 2019).…”

Lignocellulosic biomasses are primarily composed of cellulose, hemicelluloses and lignin and these biopolymers are bonded together in a heterogeneous matrix that is highly recalcitrant to chemical or biological conversion processes. Thus, an efficient pretreatment technique must be selected and applied to this type of biomass in order to facilitate its utilization in biorefineries. Classical pretreatment methods tend to operate under severe conditions, leading to sugar losses by dehydration and to the release of inhibitory compounds such as furfural (2-furaldehyde), 5-hydroxy-2-methylfurfural (5-HMF), and organic acids. By contrast, supercritical fluids can pretreat lignocellulosic materials under relatively mild pretreatment conditions, resulting in high sugar yields, low production of fermentation inhibitors and high susceptibilities to enzymatic hydrolysis while reducing the consumption of chemicals, including solvents, reagents, and catalysts. This work presents a review of biomass pretreatment technologies, aiming to deliver a state-of-art compilation of methods and results with emphasis on supercritical processes.
