Shotgun metagenomics as a ONE Health tool for better protecting human health
identify all biological material in a sample without a priori knowing what to look for, could transform the way specific key public health questions can be addressed, in a ONE Health context. Metagenomics is ...
Development, validation and application of multi-class methods for the analysis of food additives by liquid chromatography coupled to tandem mass spectrometry
extracted with sufficient recoveries. Consequently, an alternative basic methanol sample-preparation methodology was developed. After sample preparation, the obtained extracts were analysed using ...
Polycyclic aromatic hydrocarbons in spices and dried herbs and associated risk for the Belgian population
occurrence of the four EU regulated polycyclic aromatic hydrocarbons (ΣPAH4). Samples were sorted in three groups according to their use: traditional spices, exotic spices, and herbs. Benzo[a]pyrene has been ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers.
(p-mentha-1,8-dien-7-al, 2,4-pentanedione) were identified and quantified among the selected samples. Low concentrations and natural occurrences of the identified compounds suggested that these were not added as such but ...
Guidance in selecting analytical techniques for identification and quantification of non-intentionally added substances (NIAS) in food contact materials (FCMS)
guidelines that need to be taken into consideration when assessing NIAS. Different approaches to analysing NIAS in FCM s are reviewed and compared. The approaches for preparing the sample for analysis, ...
Determination of the Transport Efficiency in spICP-MS Analysis Using Conventional Sample Introduction Systems: An Interlaboratory Comparison Study
Publication Type: Peer reviewed scientific article Authors: Otmar Geiss; Ivana Bianchi; Guillaume Bucher; Eveline Verleysen; Frederic Brassinne; Jan Mast; Katrin Loeschner; Lucas Givelet; Francesco Cubadda; Francesca Ferraris; Andrea Raggi; Francesca Iaco ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers
identified and quantified among the selected samples. Low concentrations and natural occurrences of the identified compounds suggested that these were not added as such but rather originated from ...
A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market
showed good sensitivity, accuracy, and precision. It has been applied to 49 samples from the Belgian market. In 26 samples, not a single ergot alkaloid was detected while in 23 out of 49 samples at least ...
Application of a strain-level shotgun metagenomics approach on food samples: resolution of the source of a Salmonella food-borne outbreak
food samples could circumvent this need for isolation from the suspected source, but require downstream strain-level data analysis to be able to accurately link to the human isolate. Until now, this ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
sugar-coated confectionery and pristine food-grade titanium dioxide was developed. Special emphasis was placed on the sample preparation procedure, crucial to reproducibly disperse the particles before analysis. ...
