Animal and vegetable fats and oils - Determination of insoluble impurities content (ISO 663:2017)

This technical specification establishes the internationally recognized methodology for quantifying insoluble impurities within animal and vegetable fats and oils. The procedure involves a gravimetric analysis designed to assess the purity of lipid materials used in food production and industrial applications. It outlines the necessary sampling techniques, equipment requirements, and laboratory conditions to ensure accurate and reproducible results. The method is applicable to a wide range of edible fats and oils, providing a reliable means to detect foreign particles that do not dissolve in the specified solvent. By following the prescribed steps, laboratories can determine the mass of insoluble matter relative to the total sample weight. This approach supports quality control processes and helps verify compliance with product specifications. The document reflects a harmonized adaptation of global best practices, facilitating international trade and ensuring consistent analytical results across different facilities.
