“…At the final steps of the extraction run, seed flakes with little remaining oil will get the pure solvent instead of the miscella. After this process, flakes will ideally contain roughly 0.5% of oil (Regitano-d'Arce, 2006) and hexane present in the defatted seeds (meal) will be recovered in a steam toaster (Becker, 1978). In this process, the use of fresh solvent is kept to a minimum because of the high price, making up for the most efficiency of the countercurrent system (Anderson, 2018).…”

“…Phospholipids are composed of fatty acids and a phosphate group esterified to a glycerol molecule. In phospholipids, the phosphate "head" is always attached to a compound that can be an amino acid, inositol, choline or other simple amines (Medic et al, 2014;Regitano-d'Arce, 2006). The phosphate moiety is strongly hydrophilic, contrasting with the non-polar fatty acid portion, which confers surface-active properties to phosphatides.…”

“…In addition to the visual benefits on the meal, ethanol eliminates the bitterness and "bean flavor", common in legumes such as soybeans, producing more pleasant flavors and aroma in the meal. Ethanol also removes flatulence agents (oligosaccharides) and antinutritional factors (lectins and protease inhibitors) (Beckel & Smith, 1948a;Regitano-d'Arce, 2006). These advantages over hexane extraction enable the production of a high-quality protein product directed for food and feed industries.…”

Soybean oil is industrially obtained upon hexane extraction. In biodiesel production, soybean oil is submitted to phospholipid removal in order to improve its quality before transesterification. An extraction process was employed to produce ethanolic oil-rich miscella, which can be directly transesterified to produce biodiesel without prior refining. We assessed the oxidative stability of the miscella and three other soybean oils, namely degummed, alkali-refined and refined-bleacheddeodorized (RBD) oil. In vitro antioxidant assays as well as the identification and quantification of tocopherols and isoflavones were also performed. Although hexane-extracted oils showed higher tocopherol contents than miscella, this latter sample and its direct biodiesel demonstrated superior stability in accelerated tests. Miscella also outperformed hexane-extracted oils in all in vitro assays. This behavior can be explained by the presence of phenolic compounds with higher affinity to ethanol than hexane, which was confirmed by the identification of isoflavones glycitein, genistin, and acetyldaidzin, found only in miscella. This study showed that the ethanolic extraction of soybean oil generated a highly stable lipid feedstock for biodiesel manufacture.

Biodiesel is a renewable fuel that is usually narrowly defined as esters of lower alcohol and fatty acids, where the fatty acids are derived from vegetable oil, animal fat, or tallow. Biodiesel development was driven by the need to (i) increase security of energy supply for the transportation sector by having a renewable source at hand, (ii) have an environmentally friendly fuel available for the diesel combustion engine, (iii) reduce health risks, and (iv) provide the customer with a reliable fuel at a reasonable cost–benefit ratio. The production, quality, source materials, environmental benefits, and use of biodiesel are reviewed.

In the beginning, the diesel engine ran on vegetable oil, and it was peanut oil, an edible oil, that was first used for this purpose. As fossil fuels may become scarce and prices could escalate, soybean, canola/rapeseed, and other known oils are being used. As the discussion on food security, environmental protection, and energy generation continues, alternative sources of oils or fats for biodiesel synthesis are being studied. Waste frying oil and animal fats have also been used as feedstock for biodiesel production at the same time as nonedible oils ( Jatropha , castor), oil industrial plants coproduct (palm fatty acid distillate), and unconventional lipid sources (microbial oils and sewage sludge) have now been brought into light. When it comes to long‐term implementation of adoption in a commercial scale one of these so‐called nonconventional lipid sources, what has been observed is that continuous production of regular quality feedstock, adequate infrastructure for collecting or harvesting, storing, processing, and transporting (logistics) prevails; only cost‐effective choices have proven successful.
