Animal and vegetable fats and oils; Determination of polyethylene-type polymers

This technical specification establishes a standardized method for identifying and quantifying polyethylene polymers within animal and vegetable fats and oils. The procedure addresses the detection of specific synthetic additives or contaminants that may be present in lipid-based matrices. It outlines the necessary sample preparation techniques, including extraction and purification steps, to isolate the polymeric components from the complex fatty background. The method relies on specific physical and chemical properties of the polymers to distinguish them from natural fat components. Detailed instructions are provided regarding the equipment required for analysis, ensuring reproducibility across different laboratories. By defining a uniform approach, the document facilitates consistent testing results, which are essential for quality control and regulatory compliance in the food and fat processing industries. It serves as a reference for analysts performing routine checks on lipid products to detect the presence of polyethylene materials. The protocol ensures that measurements are conducted under controlled conditions to maintain accuracy and precision throughout the testing process.
