The total neutral oil of natural fats and oils consisting essentially of triglycerides and unsaponifiable matter is determined by this method. The free fatty acids and miscellaneous nonfat substances are removed by passing through a column of activated alumina. The loss is the difference between total neutral oil and 100%. This method has been satisfactorily applied to cottonseed, soybean, peanut, linseed, coconut, and sunflower oils. Application of this method to other oils has not been investigated, but it is probably applicable to practically all natural animal and vegetable fats and oils.
