Hexane and hexane containing 5% acetic acid (v/v) were used to extract lipids from soybean at room temperature and at 60 C. Hexane/acetic acid extractions yielded ca. 11% more total lipids and ca. 6–10% more neutral oil than did hexane extractions. Hexane/ acetic acid extraction at room temperature yielded the same or slightly more neutral oil than did hexane at 60 C. Thirty‐five times more phosphorus was extracted with hexane/acetic acid than with hexane; this phosphorus represented ca. 46% of the phospholipid phosphorus of soybean. Also, when hexane/acetic acid was used as the solvent, the separation of miscella from marc by filtration was about twice as rapid as the separation when hexane alone was the solvent.
