Book excerpt: In order to harmonise the determination of the mineral oil aromatic hydrocarbons (MOAH) in infant formulas (IF), a third interlaboratory comparison (ILC) JRC IF 2021-03 was organised by the Joint Research Centre (JRC) of the European Commission. This ILC was designed to (i) evaluate the consistency of the reported results for solutions mineral oil in hexane at different concentration levels; and (ii) determine the mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) composition of a specific Shell SN500* mineral oil batch. This batch was used to spike various infant formula materials for the next method validation study, planned for the beginning of 2022. The test sample named QC10, provided to the participants, consisted of a hexane solution containing the Shell SN500* mineral oil. Participants were requested to perform four different dilutions and to quantify and report MOSH and MOAH concentrations. Thirty participants from eight European countries reported results. Six of them reported consistent results for the various dilutions, and provided proper recoveries. These results were selected for the characterisation of the MOSH and MOAH percent composition in QC10. The following "reference" values and their expanded measurement uncertainty (k=2) were derived: MOSH % in SN500* = 60.1 ± 2.1 % and MOAH % in SN500* = 34.5 ± 1.2 %. In addition, the major MOSH and MOAH fractions in SN500* were identified.

Download or read book Guidance on Sampling, Analysis and Data Reporting for the Monitoring of Mineral Oil Hydrocarbons in Food and Food Contact Materials written by and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This guidance document covers specific directions for sampling and analysis of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in food and FCM in the frame of Recommendation (EU) 2017/84 for the monitoring of mineral oils. It provides guidance on the minimum performance requirements of the analytical methods fit for MOSH/MOAH monitoring. The guidance should be used by all stakeholders involved in the determination of mineral oil hydrocarbons in food and FCM, i.e. food inspectors, official control laboratories, laboratories in industry and laboratories of non-governmental organisations. This guidance aims to support the generation of reliable data for the occurrence of both fractions - MOSH and MOAH - and to enable reporting by laboratories that are already familiar with the analytical approaches and have proven their analytical performance in relevant proficiency testing (PT) schemes. For laboratories that are not familiar with MOSH/MOAH analysis, this guidance gives the minimum performance requirements and references to current analytical approaches described in the scientific literature. It does not provide standard operating procedures.

Book excerpt: Mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) consist of a mixture of various hydrocarbons that are difficult to resolve in a chromatographic column. They produce complex unresolved chromatographic signals (called humps). The quantification of total MOSH and total MOAH mass fractions requires proper integration of the respective humps, after background subtraction and the removal of the remaining interfering peaks. Such an operation is prone to subjective judgement that may increase the scatter of reported results. The European Union Reference Laboratory for Food Contact Materials (EURL-FCM) organised the first virtual interlaboratory comparison (e-ILC) "JRC-IF-2021-04" to assess the capabilities of the participants in "integrating chromatograms of mineral oils in infant formulas (IF). A set of chromatograms in "cdf" (binary) or "csv" (ascii) formats related to IF samples, hexane baselines, and retention time calibrations were provided to the participants. They were requested to submit results for the mass fraction of total MOSH and total MOAH in seven IF samples. Thirty participants registered to this round and submitted results. Most of the participants (26 out of 30) reported satisfactory peak areas for the two internal standards (CyCy and 2-MN) with a robust relative standard deviation (RSD) of 0.5 %. A significantly larger scatter of results was observed for total MOSH and total MOAH mass fractions, with RSD ranging from 6 to 18 %. This may be attributed to the various integration strategies used by the participants keeping or removing interfering peaks and overriding humps and the different baseline corrections applied. Specific guidance is provided based on the good practices identified and problems encountered by the laboratories monitoring MOSH/MOAH in infant formulas. These guidelines aim to decrease the variability of results due to the integration of chromatograms. Detailed information is provided in this report.
