This method determines the total hexane-soluble fatty acids and unsaponifiable matter in a test sample, whether present in neutral or hydrolyzed form. A procedure is included for removal of hexane-soluble unsaponifiable matter as a separate fraction when desired. Applicable to all oils or hydrolyzed fats, except coconut, palm kernel, and similar oils. This is a joint AOCS-AOAC International method (References, 1).
