Food Chemistry, Function and AnalysisDNA Techniques to Verify Food Authenticity CHAPTER 8. GMO Detection and Identification Using Next-generation Sequencing
feasibility in supporting the current genetically modified organism (GMO) routine detection systems for unauthorized GMO. Depending upon the specific samples under investigation, two categories of NGS ...
Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
included oleandrin, digoxin, digitoxin, convallatoxin, and ouabain. Samples of culinary herbs were extracted with acetonitrile and cleaned using Oasis® MAX solid-phase extraction (SPE), while samples of ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
The detected MOSH and MOAH concentrations were then compared to the action thresholds set by the Scientific Committee (SciCom) of the Belgian Food Safety Agency (FASFC) in 2017. Only one sample exceeded ...
Habitual food consumption of the Belgian population in 2014-2015 and adherence to food-based dietary guidelines.
A representative sample of the Belgian population was randomly selected from the National Population Register following a multistage stratified sampling procedure. Information on dietary intake was collected from ...
Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy
complex matrices such as food, cosmetics, medicines and environmental samples. A high degree of automation of the EM imaging and image analysis was recently developed to facilitate the measurement of ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
“nano” labeling poses several analytical challenges. This includes the many potential sources of NP s in food which can interfere with the analysis, the challenges in relation to sample preparation, the ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using ...
Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
A maximum level of 182 ng/g of PA s was detected in a Mediterranean honey, and high levels of heliotrine-type compounds were reported for the first time. An extensive sampling of honeys harvested in Belgium ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
applied to reveal the contamination state of Alternaria toxins in grapes. Among 56 grape samples, 40 (incidence of 71.4%) were contaminated with Alternaria toxins. TEN was the most frequently found ...
