What are the optimal conditions for peanut oil extraction?
The optimal conditions for the extraction process were found to be a pressure of 8000 psi and a temperature of 80 °C. Lower temperatures resulted in decreased extraction rates. Furthermore, a 3-min holding time was the most effective for dissolving peanut oil up to the saturation level in the SC-CO 2 fluid.
How to extract oil from peanuts?
Chemical methods of oil extraction from peanuts. 3.1. Organic Solvent Extraction When extracting oil from oilseeds, the organic solvent is used to separate crude vegetable oil from the meal, which contains both proteins and carbohydrates too. The most frequently utilized organic solvent for this process is hexane [ 18, 71 ].
Does PDPM extract oil from peanuts?
The oil yield was not evaluated in this study, but the researchers were very interested in utilizing the by-product of this extraction (i.e., the meal), knowing that 70 kg of PDPM was recovered out of 100 kg of peanuts [ 21 ].
How to extract residual oil from roasted peanuts?
The residual oil was recovered using n-hexane solvent extraction after continuous pressing. Peanuts that had been roasted at 180 °C for 10 min were ground into powder, treated with n-hexane, and agitated at 200 rpm for 2 h. The process of extraction was repeated twice using n-hexane.
