Cottonseed oil of higher Halpen‐acid‐moiety concentration can be obtained by hot hexane extraction of cotton‐seed meats from which the oil has already been partially extracted at room temperature. The intensity of the Halphen‐test color solution is affected by many nitrogen‐containing substances including soybean phosphatides.
