“…Although the mechanical pressing method is quite popular for flaxseed oil processing, a drawback of this technique is the low extraction recovery of the oil. To improve the yield of extracted oil, many new extraction methods, for example, ultrasound-assisted extraction, microwaveassisted extraction, supercritical CO 2 extraction, subcritical extraction, three-phase partitioning, enzyme-assisted three-phase partitioning etc., have been developed (Kulkarni et al, 2017;Ren et al, 2015;Rombaut et al, 2017;Piva et al, 2018;Sharma et al, 2019;Suri et al, 2020;Szydlowska-Czerniak et al, 2020;Tan et al, 2016).…”

“…Atherosclerosis refers to one kind of the diseases that caused by depositing and accumulating of the lipids in blood cell walls. The formation and development of atherosclerosis are attributed to many factors such as interleukin 1-b, hypercholesterolemia, tumor necrosis factor, eicosanoids cytokines, platelet-activating factor and reactive oxygen from subcritical propane presented low acidity, showing a better quality compared to flaxseed oil from mechanical extraction (Piva et al, 2018). Piva et al (2017) employed three methods to extract flaxseed oil, and showed that subcritical propane extraction had a higher yield (28.39%) compared to other methods.…”

Flaxseed is rich in ?-linolenic acid (ALA), lignans, proteins and dietary fibers, which has been considered as an important food ingredient. As one of most functional ingredients in flaxseed, flaxseed oil could provide many potential health benefits, such as cardiovascular protection, anti-tumor, anti-inflammatory, live protection, diabetes treatment, etc. Besides mechanical pressing and solvent extraction for flaxseed oil, various new extraction processes, for example, microwave-assisted extraction, supercritical CO2 extraction, subcritical extraction, three-phase partitioning, enzyme-assisted three-phase partitioning, etc., have been investigated. Currently, flaxseed oil has been incorporated into some regular food formulations including liquid or solid powder drink, meat products, baking foods, etc. However, due to high ALA in flaxseed oil, it is a great challenge for the development of flaxseed-oil based products. In present paper, the latest development of the extraction of flaxseed oil, the potential benefits of flaxseed oil, and flaxseed oil-based foods, were reviewed. Regarding the studies of flaxseed oil in our group was also highlighted.

“…Subcritical extraction is based on the technique of using a solvent as an extractant. Piva et al (2018) used subcritical propane for the extraction of flaxseed oil. Propane is preffered as solvent as it has high solvation properties and is non-toxic.…”

Flaxseed is the chief oilseed crop that is grown in many regions of the world for medicinal and nutritional purposes. It has been used for oil and fiber since centuries. Flaxseed has an enormous role in functional foods for its nutritional and pharmaceutical values. Among the various components of flaxseed lignans, phenolic acids, proteins and oil are of the main interest. Oil and lignans have prime concentrations in the flaxseed. To study the extraction of these compounds, various extraction methods have been investigated. Oil has been extracted by mechanical pressing in ancient times but presently new techniques have been developed. These include microwave assisted extraction, supercritical CO2 extraction, ultrasonic assisted extraction, etc. Enzymes are also gaining importance in the extraction of oil, lignan and proteins as they give more yield of compounds and easily degrade the cell wall of the flaxseed. The need of these novel techniques lies in the fact that traditional methods have different shortcomings like low yield, more time, more energy and less environmental friendly. This review put on a view to different techniques which have been investigated for the extraction of different components of flaxseed. Quality evaluation and comparison of flaxseed oils and other bioactive components obtained by newer techniques with those produced by conventional extraction methods is also reported.

“…Assim, os valores de K sa0 e K fa0 representados pelo modelo Sovová para a curva de extração, representam as transferências de massa interna e externa, indicando que o parâmetro difusional é menos representativo quando comparado com a etapa de convecção na extração por fluido supercrítico do óleo de Bidens pilosa (Kitzberger et al, 2009;Piva et al, 2018). A predição das curvas de extração por fluido supercrítico pelo modelo Sovová (1994) Em relação as curvas de extração, observou-se que a condição de 179 bar e 74 153°C retratou um desvio relativo de 2,73%, de tal forma que o modelo de Brunner (1984) apresentou o melhor ajuste para os dados experimentais.…”
