“…Various solvents, mainly from renewable resources, have been tested as possible hexane substitutes (Fine et al, 2013;Sawada et al, 2014;Sicaire et al, 2015a). Ethanol seems a promising alternative solvent.…”

“…Oil extraction efficiency with ethanol can be increased by raising the extraction temperature and/or lowering water content in the ethanol (Rittner, 1992;Sawada et al, 2014;Toda et al, 2016). In particular, Rao and Arnold (1956) demonstrated that rapeseed oil solubility in ethanol-water azeotrope increased from < 2 wt.% at room temperature to 11.3 wt.% at 90°C.…”

“…In particular, Rao and Arnold (1956) demonstrated that rapeseed oil solubility in ethanol-water azeotrope increased from < 2 wt.% at room temperature to 11.3 wt.% at 90°C. However, oil solubility in ethanol-water mixtures falls steeply when the water content in the mixture reaches 6 wt.% (Rodrigues and Oliveira, 2010;Sawada et al, 2014).…”

-In the extraction of vegetable oils, the idea of using ethanol as a solvent, allowing solvent recycling without distillation, can be attested as early as 1948 (Beckel), yet it is now seldom envisaged. The development of organic farming and a growing demand for a more natural diet prompted us to revisit this approach, which takes advantage of the relatively low affinity of ethanol for lipids to produce pure crude oils and meal with higher protein content. This method is based on the change of oil solubility in ethanol with temperature. Rapeseed oil extraction was carried out by hot pressurized ethanol (subcritical extraction condition). Oil was then recovered by cooling the miscella and demixing of two phases, an oil-rich phase and a solvent-rich phase. This study, after verifying the kinetics of extraction, focused on the optimization of the demixing temperature based on the amount and quality of recovered oil. The results show that ethanol extraction followed by cold demixing of the miscella makes it possible to obtain a high quality oil, free of free fatty acids and phospholipids.

“…In industry, the process of oil extraction from typically applies mechanical pressing process, expelling (Sawada et al, 2014), and organic solvent extraction with hexane (Hammond et al, 2005). However, the lower oil recovery from expelling, and the safety and environment issues (Li et al, 2004, Oliveira et al, 2013 resulted from solvent extraction are main challenges in soybean oil industry.…”

In the industry, expelling and hexane extraction are the two typical processes for soybean oil production. However, the low efficiency and hazardous chemical problem are the main issues for these two processes respectively. Enzyme assisted aqueous extraction process (EAEP) is applied to increase the efficiency without using organic solvent, which is replaced by water. The environmental impact analysis of these three processes are based on their mass flows, energy consumption and global warming potential. For mass flows, the environmental impact indices were calculated based on mass balance of input and output components. Energy consumption was used to evaluate the carbon dioxide and greenhouse gas (GHG) emissions. According to results, hexane extraction has the highest environmental impacts due to the application of organic solvent; EAEP has the highest CO 2 and GHG emissions because of more requirements for soybean flaking processes.

“…The solvent extraction is the efficient and usual method for oil production, and that can be applied to seeds with oil content lower than 20% and the oil crops with higher oil content (Bernardini, 1983). Hexane extraction is the traditional technique that is utilized in the industry because of its low cost and high solubility (Hammond et al, 2005, Sawada et al, 2014.…”
