The kernels or beans are then cracked into smaller pieces to increase surface area, making the oil more accessible during extraction. Next is neutralization, which removes free fatty acids using an alkaline solution, creating soapstock that is later separated.
Press Cake Solvent Extraction Method for Maximizing Oil Yield
