“…(PFCs were not included in the spiking solution.) Nutrient elements, including calcium, copper, iron, magnesium, manganese, phosphorous, potassium, sodium, and zinc, and the toxic metal mercury, were determined in the milk samples, and the results are provided on the Certificates on Analysis as reference mass fractions [18,20,31].…”

Four new Standard Reference Materials (SRMs) have been developed to assist in the quality assurance of chemical contaminant measurements required for human biomonitoring studies, SRM 1953 Organic Contaminants in Non-Fortified Human Milk, SRM 1954 Organic Contaminants in Fortified Human Milk, SRM 1957 Organic Contaminants in Non-Fortified Human Serum, and SRM 1958 Organic Contaminants in Fortified Human Serum. These materials were developed as part of a collaboration between the National Institute of Standards and Technology (NIST) and the Centers for Disease Control and Prevention (CDC) with both agencies contributing data used in the certification of mass fraction values for a wide range of organic contaminants including polychlorinated biphenyl (PCB) congeners, chlorinated pesticides, polybrominated diphenyl ether (PBDE) congeners, and polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) congeners. The certified mass fractions of the organic contaminants in unfortified samples, SRM 1953 and SRM 1957, ranged from 12 ng/kg to 2200 ng/kg with the exception of 4,4'-DDE in SRM 1953 at 7400 ng/kg with expanded uncertainties generally <14 %. This agreement suggests that there were no significant biases existing among the multiple methods used for analysis.

“…Analysis using the method mentioned earlier showed the supplement contained 1.38 g 25OHD 3 /100 g, which was in line with the manufacturer's claim (1.25 g/100 g). In addition, a dairy‐based standard reference material (SRM 1849) from the National Institute of Standards and Technology, USA, which certifies vitamin D 3 at 0.251 mg/kg ± 0.027 was analysed. All replicates (n = 4) were within these acceptable certified limits.…”

Aim The aim of this study was to obtain preliminary indicative data for vitamin D3 (cholecalciferol) and 25‐hydroxycholecalciferol (25OHD3) in Australian chicken egg yolk (Gallus gallus domesticus, Linnaeus, 1758), comparing data with the egg yolk of other species, crocodile (Crocodylus porosus, Schneider, 1801) and salmon (Salmo salar, Linnaeus, 1758). Methods Convenience samples of chicken eggs were obtained from a producer known to fortify feed with 25OHD3 as well as D3 (Brand A; n = 6), a producer with an unknown feeding protocol (Brand B; n = 6) and a producer known to use low levels of only feed vitamin D3 (University of Sydney; n = 4). Salmon roe (50 g jar) was obtained from a retail outlet and crocodile eggs (n = 2) from a commercial crocodile farm. Egg yolks and whole salmon roe were analysed for vitamin D3 and 25OHD3 by high‐performance liquid chromatography. Results Brand A and B chicken egg yolks contained 2.9 and 2.1 μg vitamin D3/100 g, respectively, while University of Sydney eggs contained lower concentrations (0.5 μg/100 g). Further, yolk from brand A and B chicken eggs contained 4.2 and 1.4 μg 25OHD3/100 g, respectively. Salmon roe contained 6.3 μg vitamin D3/100 g and vitamin D3 content of two crocodile egg yolks differed widely (10.9 and 0.7 μg/100 g). Conclusions The vitamin D in chicken eggs has the potential to contribute considerably to the vitamin D content of the Australian diet, up to 3.8 μg vitamin D equivalents per egg, depending on the form of feed vitamin D. Further representative samples of all edible or potentially edible Australian egg species require analysis for public health nutrition purposes.

“…In addition to the ID LC-MS and ID LC-MS/MS methods described above for the vitamins, in the late 2000s two independent GC methods, GC-FID and GC-MS, were implemented for determination of fatty acids in food. As a result, SRM 1849 was issued with certified values assigned for 43 nutrients including all WSVs and FSVs typically fortified in foods, individual fatty acids, and nutritional elements, with reference/indicative values assigned for an additional 42 constituents including additional vitamins and elements, proximates, amino acids, and nucleotides [61]. Measurements from collaborating laboratories were still an important contribution to the value assignment process; however, the increased capabilities to provide two independent methods for most of the vitamins and the fatty acids resulted in a significant increase in the number of values denoted as certified in SRM 1849 compared to SRM 1846.…”

“…Value assignment for SRM 3280, SRM 1849, and SRM 1849a illustrates the extensive application of the multiple analytical methods approach used at NIST for organic nutrients in food and dietary supplement-matrix CRMs and will be presented in detail as an example of this approach. For these three CRMs, results from multiple analytical techniques at NIST, multiple analytical techniques at a collaborating laboratory (USDA), results from two interlaboratory studies, i.e., the European Committee for Standardization (CEN) and GMA, and results from analyses by the manufacturer of the infant formula materials were used to assign the certified and reference values [44,61]. The certified values and the multiple methods used to assign these values for SRM 3280, SRM 1849, and SRM 1849a are summarized in Table 4.…”

For over 40 years, food-matrix certified reference materials (CRMs) have been available for determination of trace element content, and a wide variety of materials are available from most producers of CRMs. However, the availability of food-matrix CRMs for organic nutrients has been more limited. The European Commission (EC) Bureau Communautaire de Référence (BCR) and the National Institute of Standards and Technology (NIST) introduced food-matrix CRMs with values assigned for vitamins and other organic nutrients such as fatty acids and carotenoids in the 1990s. The number of organic nutrients for which values were assigned has increased significantly in the past decade, and the approach and analytical methods used for assignment of the certified values have also evolved. Recently, dietary supplement-matrix CRMs such as multivitamin tablets with values assigned for vitamins and carotenoids, and fish and plant oils with values assigned for fatty acids have appeared. The development, evolution, and improvement of food- and dietary supplement-matrix CRMs for determination of vitamins, carotenoids, and fatty acids are described, with emphasis on CRMs made available in the past 10 years. Recent food and dietary supplement CRMs for the determination of organic nutrients include infant formula, multivitamin tablets, milk and egg powders, breakfast cereal, meat homogenate, blueberries, soy flour, fish and plant oils, dry cat food, and protein drink powder. Many of these food- and supplement-matrix CRMs have values assigned for over 80 organic and inorganic nutrients, toxic elements, proximates, and contaminants. The review provides a critical assessment of the challenges and evolving improvements in the production and the analytical methods used for value assignment of these CRMs. The current status and future needs for additional food- and dietary supplement-matrix CRMs for organic nutrients are also discussed.
