A method is proposed for the determination of the mutton tallow content of mixed beef and mutton tallow samples. The calculation is based on the determination of conjugated diene, trans acids, and mono cis unsaturated acids in the sample. The analytical findings are employed in a single equation which is weighted to minimize uncertainty due to natural variation. The method is largely independent of the degree of “seeding” of the tallow prior to sampling and is accurate to approximately ±14%. This accuracy is considered reasonable in view of the natural variations of the two fats and their close analytical similarity.
