ABSTRACT:
Hexane and mixtures of hexane containing 2 to 25% acetic acid (v/v) were used to prepare oil and protein from glanded cottonseed by solvent extraction. As the amount of acetic acid in the solvent increased, the amounts of total lipid, phospholipid, neutral oil, and gossypol in each miscella increased, but the amount of free fatty acids did not change significantly. The solubility of the protein in 0.02N NaOH did not decrease until the amount of acetic acid in the solvent used to prepare each meal increased to a point between 4 and 10 percent. The drainage of the miscella (solvent-lipid solution) through the marc (insoluble residue) was much more rapid when the solvent was hexane-acetic acid than when it was hexane alone.
