Milk-based infant foods. Determination of fat content. Gravimetric method (Reference method) (ISO 8381:2000)

This technical specification establishes a precise methodology for quantifying fat content in fat-based infant formula products. The procedure employs the gravimetric technique, which serves as a reference method for ensuring consistency and accuracy in laboratory analyses. Designed to align with international frameworks, this document outlines the necessary equipment, reagents, and step-by-step operational protocols required for execution. It details the process of sample preparation, extraction, and weighing to determine the total fat percentage by mass. The approach is applicable to various types of lipid-rich infant nutrition formulations, providing a standardized means for quality control and compliance assessment. By adhering to these defined procedures, laboratories can produce reliable data that reflects the true nutritional composition of the product. The methodology emphasizes strict control over variables such as temperature and drying conditions to minimize experimental error. This document facilitates uniformity in testing results across different facilities and regions, supporting the verification of product specifications without altering the fundamental nature of the analytical technique itself.
