During the extraction process, oil-bearing seeds like soybean, sunflower, cotton, groundnut, mustard, sheanut, canola, rapeseed and rice bran have to be correctly prepared. Key preparation steps in extraction include seed cleaning, cracking, cooking, flaking, expanding and cooling. Depending on protein requirement, seeds can also be partially or fully dehulled. These applications are for oil seeds like soybean, cotton, sunflower, canola and rapeseed, mustard, castor, sesame, sheanut and groundnut, among others.
