Supercritical fluid extraction was successfully used to extract peanut oil from peanuts at temperatures between 40 and 80 °C and pressures of 5000-7000 psi. Static/dynamic cycling was used with a 10 minute static soak time, followed by a 10 minute dynamic interval. The overall extraction time was held constant at 3 hours. Peanut oil yield was determined gravimetrically. The crossover phenomenon was observed with the crossover pressure occurring at 6000 psi. Above the crossover pressure, an isobaric increase in temperature has a positive effect on the extraction yield, while below the crossover pressure an increase in temperature resulted in a decrease in oil yield. Yields between static/dynamic cycling and continuous runs were comparable, suggesting CO2 usage could be reduced by half by static/dynamic cycling, creating a cost effective, greener process.
