Certification report: The certification of the mass fraction of aflatoxins B1 and G1 in paprika powder: ERM®-BD286
This report describes the production of ERM®-BD286, which is a matrix material certified for the mass fraction of aflatoxins B1 and G1 in paprika powder. This material was produced following ISO 17034:2016 [1] and is certified in accordance with ISO Guide 35:2017 [2].
The starting material consisted of two naturally contaminated batches of paprika powder. Both batches were thoroughly sieved, cryogenically milled, and homogenised before they were mixed in equal quantities. After homogenisation and sieving the powder was manually filled in amber glass bottles. The bottles were packed in plastic-aluminised sachets that were heat sealed. The sachets were sterilised by -irradiation.
Between-unit homogeneity was quantified and stability during dispatch and storage were assessed in accordance with ISO Guide 35:2017 [2]. Within-unit homogeneity was quantified to determine the minimum sample intake.
The material was characterised by an interlaboratory comparison of laboratories of demonstrated competence and adhering to ISO/IEC 17025:2005 [3]. Technically invalid results were removed but no outlier was eliminated on statistical grounds only.
Uncertainties of the certified values were calculated in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM) [4] and include uncertainties related to possible inhomogeneity, instability and characterisation.
The material is intended for the quality control and assessment of method performance. As with any reference material, it can be used for establishing control charts or validation studies. The certified reference material is available in amber glass bottles packed in aluminised plastic sachets each containing at least 100 g of paprika powder. The minimum amount of sample to be used is 10 g.
