TL;DR: In this article, the authors determined a less hazardous, cheaper and less toxic alternative solvent for hexane for extraction of oil from different oilseeds showing equivalent oil yield and oil quality.
Abstract: The aim of the current research was to determine a less hazardous, cheaper and less toxic alternative solvent for hexane for extraction of oil from different oilseeds showing equivalent oil yield and oil quality. A full factorial design with three levels of extraction temperature (80, 100 and 120 °C) and three levels of extraction time (40, 65 and 90 min) with constant solvent to seed ratio value of 4:1 was used to extract the oil. Maximum oil was recovered from canola followed by flax, mustard and camelina. The oil content of canola was found in range of 21.08–36.44, and 25.12–40.38 % for hexane and ethyl acetate, respectively. The heating values of oil extracted from all oilseeds using hexane and ethyl acetate were found in the range of 38.04–39.98 and 37.98–39.37 MJ/kg, respectively. Least viscosity was found for flax seed using hexane followed by camelina, canola and mustard as compared to ethyl acetate. Viscosity of flax oil ranged from 27.23–37.19, and 31.16–55.52 cP for hexane and ethyl acetate solvents, respectively. Considering human safety, less environmental impact, comparable oil yield and quality parameters, ethyl acetate can be a promising alternative to hexane.

TL;DR: Of the organic solvents tested, highest biotransformation activities were observed with hexane and hexadecane, and lowest activities occurred with chloroform and toluene, while phospholipids were detected in reaction media from biocatalytic systems which exhibited cell damage in electron micrographs.
Abstract: Biotransformation of benzaldehyde and pyruvate to (R)-phenylacetyl carbinol bySaccharomyces cerevisiae was investigated in two-phase aqueous-organic reaction media. With hexane as organic solvent, maximum biotransformation activity was observed with a moisture content of 10%. Of the organic solvents tested, highest biotransformation activities were observed with hexane and hexadecane, and lowest activities occurred with chloroform and toluene. Biocatalyst samples from biphasic media containing hexane, decane and toluene manifested no apparent cell structural damage when examined using scanning electron microscopy. In contrast, cellular biocatalyst recovered from two-phase systems containing chloroform, butylacetate and ethylacetate exhibited damage in the form of cell puncturing after different incubation periods. Phospholipids were detected in reaction media from biocatalytic systems which exhibited cell damage in electron micrographs. Phospholipid release was much lower in the two-phase systems containing toluene or hexane or in 100% aqueous biocatalytic system.

TL;DR: In this article, the recovery of oil and protein fractions from corn germ (CG) generated as a byproduct during flour processing was investigated, and the protein extract produced from this partially defatted meal showed interesting characteristics such as the highest protein concentration (48.5%), the highest foaming properties (FC and FS>−84%), high WAC (2.33g water/g extract) and EAI (231 m2/g).
