Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market

detection were developed with a focus on very low LOQ s and validated for the analysis of 16 PA s and 14 PANO s in honey, honey based candies and snacks as well as beehive products based food supplements. ...

Analysis of mineral oil in food: results of a Belgian market survey

components from food contact materials into various foods has been reported. The analysis of mineral oil in food is complicated since it consists of mineral oil saturated hydrocarbons (MOSH) comprising ...

Techniques Gram-Negative Bacteria Humans Multiplex Polymerase Chain Reaction RNA, Ribosomal, 16S Abstract: OBJECTIVES: The objective of this study was to design and validate a genotyping method for multiplex ...

Study of the possible migration risks of food contact materials for children under 3 years

Monitoring and quantification of these compounds was done using GC- and LC-QqQ- MS methods, for which several validation parameters were determined (sensitivity, selectivity, linearity, accuracy, precision, ...

Construction of Nontoxigenic Mutants of Nonproteolytic Clostridium botulinum NCTC 11219 by Insertional Mutagenesis and Gene Replacement.

for food challenge and process validation studies with gIICb. In addition, this work expands the clostridial genetic toolbox with a new gene replacement method that can be applied to replace any gene in ...

Evaluation of the migration of chemicals from baby bottles under standardised and duration testing conditions.

toxicity assessment, the most toxic migrating compounds were selected to be monitored and quantified using validated GC- and LC-QqQ- MS methods. The effect of several ‘real-life-use conditions’, such as ...

Generation and Characterization of Six Recombinant Botulinum Neurotoxins as Reference Material to Serve in an International Proficiency Test.

and validated amino acid analysis, respectively. In addition, BoNT/A₁, B₁, E₁ and F₁ were successfully detected by immunological assays, unambiguously identified by mass spectrometric-based methods, and ...

A multiplex oligonucleotide ligation-PCR as a complementary tool for subtyping of Salmonella Typhimurium

markers was confirmed in a serial passage experiment. The validation of the MOL- PCR assay for subtyping of S. Typhimurium and S. 1,4,[5],12:i:- on 519 isolates shows that the method is rapid, reproducible, ...

Statistical framework for detection of Genetically Modified Organisms based on Next Generation Sequencing

number and diversity of genetically modified (GM) crops has significantly increased, their analysis based on real-time PCR (qPCR) methods is becoming increasingly complex and laborious. While several ...

Low-calorie sweeteners in food and food supplements on the Italian market.

samples were analysed via UPLC- MS / MS. The method was in-house validated for the analysis of seven LCS s (aspartame, acesulfame-K, saccharin, sucralose, cyclamate, neotame and neohesperidin ...
