Determination of caramel colorants' by-products in liquid foods by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
Volume 31, Issue 10, p.1652-60 (2014) Keywords: Acetic Acid Analytic Sample Preparation Methods beer Beverages Chromatography, High Pressure Liquid Condiments Food Coloring Agents Food Contamination Food ...
A proteomics approach for the quantification of Staphylococcus aureus enterotoxins a and b in several matrices using uplc-msms analysis.
high specificity of the method. The sample is then injected and analysed using online Solid Phase Extraction (SPE) – UPLC – MS / MS. Analytes of interest are trapped on the SPE-column, while e.g. ...
Development and validation of qualitative SYBR®Green real-time PCR for detection and discrimination of Listeria spp. and Listeria monocytogenes.
and the “Definition of minimum performance requirements for analytical methods of GMO testing”. The developed assays target the iap, prs and hlyA genes that belong to or neighbour the virulence cluster ...
On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
method (10min) was assessed for three concentration levels and were found to be less than 8% for each analyte while the accuracy was between 89 and 113%. To further improve the sensitivity of this approach ...
Identification of potential migrants from printing inks used on paper and board food contact materials
substances can be used. One approach is to focus on pre-selected target analytes, with known fragmentation patterns and retention times. In the presented work, a screening method for more then 120 analytes was ...
Dietary intake of artificial sweeteners by the Belgian population.
for cyclamate, 17% for saccharin, and 16% for sucralose of the respective ADI s. Assessment of intake using a Tier 3 approach was preceded by optimisation and validation of an analytical method based on ...
A rapid and environmental friendly determination of the dithiocarbamate metabolites ethylenethiourea and propylenethiourea in fruit and vegetables by ultra high performance liquid chromatography tandem mass spectrometry.
Thiocarbamates Thiourea Vegetables Abstract: Previous published methods for the analysis of ETU and PTU are time-consuming and furthermore use dichloromethane (DCM) for extraction or clean-up. This study details ...
The occurrence and formation of benzene in foodstuffs
analytical method for the determination of benzene in all food matrices was in-house validated (LOD =0.5 �g.kg-1). A survey of 450 food samples from Belgium showed that benzene was omnipresent. A probabilistic ...
A theoretical introduction to "combinatory SYBRGreen qPCR screening", a matrix-based approach for the detection of materials derived from genetically modified plants.
Genetically Modified polymerase chain reaction Abstract: The detection of genetically modified (GM) materials in food and feed products is a complex multi-step analytical process invoking screening, ...
