This Document describes the method for determining the saponification value of animal and vegetable fats and oils. The saponification value is an indicator of determining the content of free fatty acids and glycerides in oils or fatty acids. This Document applies to refined animal and vegetable fats and oils, and crude animal and vegetable oils. This Document does not apply to products containing inorganic acids unless the inorganic acids can be determined separately. The saponification value can also be calculated from fatty acid data obtained by gas chromatography analysis as shown in Appendix B. For this calculation, it shall be ensured that the sample is free of impurities or thermal degradation products.
