Certified reference materials (CRMs) play a critical role in validating the accuracy of nutrient data for food samples.

A number of available food CRMs of differing matrix composition have assigned concentrations for various nutrients, along with associated uncertainty intervals (UIs) for those values. These CRMs have been used extensively in the Cited by: Reference materials to evaluate measurement systems for the nutrient composition of foods: results from USDA’s reference nutrient concentrations in 26 certified reference materials (CRM) submitted to contract laboratories, blinded, as part of the qualifying process for analytical limited for organic by: Margolis SA (Ed) () Reference materials for organic nutrient measurement, NBS Special Publication No.

That report identified the most urgently required chemical reference materials based on certain key themes for oceanographic research. At the top of the list of the new reference materials needed were standards for the measurement of nutrients, with the statement: “There is an urgent need for a certified reference material for nutrients.

Development of Reference Measurement Procedures. For clinical analytes in which the measurand has been defined, the next step towards the goal of the production of a higher-order reference material and, ultimately, a reference measurement system, is the development of a reference measurement by: Unfortunately, there are few certified reference materials (CRMs) and proficiency schemes for animal feeds.

In cases of complex mixtures of pro- or anti-nutrients, e.g. tannins, structure-function relationships have not yet been elucidated and, therefore, no particular assay can be recommended to plant breeders.

Reference materials (RMs) represent samples of well-established properties used for the assessment of analytical methods. More rigorous materials − certified reference materials (CRMs) or standard reference materials (SRMs), issued by the National Institute of Standards and Technology – NIST, USA (Inn et al., ; Outula et al., ) have property.

Over 30 food-matrix Standard Reference Materials (SRMs) and Reference Materials (RMs) are available to support these measurement needs; examples include infant formula, baby food, meat homogenate, fish tissue, baking chocolate, peanut butter, spinach, and food oils.

This guide provides procedures for using a reference material with a known emission rate of a volatile organic compound (VOC) to estimate the bias associated with a VOC emission chamber test.

This guide may be used to assess measurements of VOC emissions conducted in a variety of environmental chambers, such as small-scale chambers. Evolution of reference materials for the determination of organic nutrients in food and dietary supplements—a critical review.

A certified reference material (CRM) is a “reference material. The committee recommends the development of a seawater-based reference material containing the nutrient elements: nitrogen (as NO 3), phosphorus (as PO 4), and silicon (as Si (OH) 4) at concentrations similar to those in oceanic deep waters (40 µM for NO 3, 3 µM for PO 4, and µM for Si (OH) 4) and certified for these constituents.

certified reference material for nutrients. Completed global surveys already suffer from the lack of previously available standards, and the success of future surveys as well as the development of instruments capable of remote time-series measurements will rest on the availability and use of good nutrient reference materials”.

This book covers the topics with reference materials which are important tools in assuring the uniformity, comparability, metrological traceability of measurement results in scientific research, production of substances and materials, assuring safety of human life and of environment.

USP food ingredient reference materials help you verify the identity, quality, and purity of food ingredients you buy or sell.
