Which solvent is used to extract residual oil from peanut press cake?
4. Conclusions The solvents hexane and ethanol were evaluated for the extraction of residual oil from peanut press cake. Ethanol exhibited a similar extraction capacity to hexane; however, the extraction conditions considering the multistage cross-current configuration were different.
Does ethanol extract oil from peanut press cake?
In general, both solvents are effective in oil extraction [21,22], and ethanol is responsible for extracting a great amount of nonlipid compounds . Studies evaluating the extraction of residual oil from peanut press cake are scarce.
Does hexane extract residual oil from peanut cake?
Tate et al. evaluated the performance of hexane in the extraction of residual oil in peanut cake with the subsequent use of hydroalcoholic solution (80% ethanol) to remove pigments and the bitter taste.
What is the difference between solvent extraction and cold pressing?
In general, the oils obtained from solvent extraction showed higher acidity and more pronounced color than the oil extracted by cold pressing. The oil obtained with ethanol presented free acidity values that were 44% and 71% higher than the acidity present in the oils obtained with hexane and by pressing, respectively.
