Modelling the pesticide transfer during tea and herbal tea infusions by the identification of critical infusion parameters.
limits. Consideration of the transfer of pesticides from the leaves (called transfer factors) to the brew is essential to assess the associated risk. This study identified infusion parameters influencing ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
various living organisms or the cultivation parameters. Moreover, the current methods require a subsequent but not always successful isolation. In part due to these two drawbacks, not all outbreaks can be ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
of NC exist, i.e. bacterial NC (BNC), nanofibrillated cellulose (NFC), and cellulose nanocrystals (CNC). The biological sources and processing conditions affect several physicochemical parameters of ...
Regulatory safety assessment of nanoparticles for the food chain in Europe
that may retain properties at the nanoscale. Key parameters and threshold values for establishing the presence of small particles, the techniques and methods for characterisation in complex matrices, as ...
Microbiological safety of aged meat.
to a description of the different stages, data were collated on key parameters (time, temperature, pH and a) using a literature survey and questionnaires. The microbiological hazards that may be ...
Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
impurities and enriching the target analytes in different feeds. The critical parameters affecting the performance of the solid-phase extraction (SPE) procedure were carefully optimized, and 20% acetonitrile ...
Estimating national and subnational nutrient intake distributions of global diets
have not been consistently disaggregated by sex and age groups, and their parameters and full distributions are often not publicly available. OBJECTIVES: We sought to derive usual intake distributions ...
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.
the particles’ number concentration and a number of cumulative particle size distribution parameters (D0, D10, D50, D99.5, D99.8 and D100). The evaluated method’s performance characteristics were, the ...
Comprehensive toxicokinetic analysis reveals major interspecies differences in absorption, distribution and elimination of citrinin in pigs and broiler chickens
Toxicology, Volume 141 (2020) Abstract: A comprehensive toxicokinetic analysis of citrinin (CIT) revealed interspecies differences for all toxicokinetic parameters and in absolute oral bioavailability. Oral ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
methods using spiked samples at three concentration levels (0.5–5 and 25 ng g−1). The parameters accuracy and precision fulfill the criteria. Calibration curves are linear between 0.5 and 50 ng −1. The ...
