Standard Reference Materials to Support Measurement of Fatty Acids
Lane C. Sander, Michele M. Schantz, Katherine E. Sharpless, Stephen A. Wise
The National Institute of Standards and Technology offers a variety of natural-matrix and solution-based Standard Reference Materials (SRMs) that are characterized for fatty acid composition. The natural-matrix SRMs are intended primarily for use as control materials, but other uses include method validation, the development of new analytical methods, and use as a component in achieving traceability of measurements. The use of SRMs to support the measurement of fatty acids is relevant to a broad spectrum of applications including compliance with and accuracy of nutritional labeling, food manufacturing tolerances (e.g., infant formulas), traceability of measurements for food exports, clinical nutritional measurements, and characterization of alternative energy sources (e.g., biodiesel). Currently, nearly 30 SRMs are available with certified, reference, and information values reported for fatty acids. Additional SRMs are under development that will complement these reference materials by providing fatty acid profiles in different types of matrices.
