Aug 09, 2024· Solvent extraction of soybean . Basic principles and elements of solvent extraction; Oil extraction is to extract the oil from the embryo by wetting and infiltration, molecular diffusion and convective diffusion with solvent which can dissolve the oil. The mixture of solvent and fat is then separated to recover the solvent to obtain the crude oil.
Kinetics of soybean oil extraction using ethanol as
The data on the kinetics of extraction of soybean oil and free fatty acids using absolute and hydrous ethanol as solvents can be observed in Fig. 1, Fig. 2.Through the experimental data shown in Fig. 1 it is possible to verify that the oil contained in the soybean migrates quickly to the extracted phase at the beginning of the extraction process and then the extraction rate decreases, it being
