Two extraction methods based on solid liquid and Quick, Easy, Cheap, Effective, Rugged Safe procedure were developed for the determination of 21 triazole compounds 5 metabolites, including derivative metabolites as 1,2,4-triazole 1,2,4-triazol 1-yl-acetic, in courgette, orange, grape strawberry. The analysis was performed 10.5 min, using ultra-high performance chromatography coupled to Q-Orbitrap mass analyser. proposed method validated according SANTE 12682/2019. Limits quantification ≤10...
In this study, 21 pesticides and 4 aflatoxins were monitored in baby food marketed Brazil, applying ultra-high-performance liquid chromatography coupled to quadrupole-Orbitrap mass spectrometry (UHPLC-Q-Orbitrap-MS). The quick, easy, cheap, effective, rugged, safe (QuEChERS) extraction method combined with dispersive solid-phase (d-SPE) clean-up was applied primary secondary amine (PSA), octadecylsilane (C18) C18 silica coated zirconium dioxide (Z-Sep+) used during the stage. Suitable...
Pre-harvest sprouting is a frequent problem for wheat culture that can be simulated by laboratory-based germination. Despite reducing baking properties, has been shown to increase the bioavailability of some nutrients. It was investigated whether cultivars bearing distinct grain texture characteristics (BRS Guaraim, soft vs. BRS Marcante, hard texture) would have different behavior in terms changes phytochemical compounds during Using LC-Q-TOF-MS, higher contents benzoxazinoids and...
Flutriafol is a systemic triazole fungicide that used to control diseases in various crops. A study was developed evaluate the metabolism and dissipation of flutriafol two different scenarios: laboratory greenhouse conditions. Courgette tomato samples treated with commercial product (IMPACT® EVO) at manufacturer recommended dose were analyzed, courgette also double dose. Ultra-high-performance liquid chromatography coupled Q-Orbitrap mass spectrometry (UHPLC-Q-Orbitrap-MS), performing...
The development and validation of a method to determine flonicamid its metabolites as TFNA (4-trifluoromethylnicotinic acid), TFNG (N-(4-trifluoromethylnicotinoyl) glycine) TFNA-AM (4-trifluoromethylnicotinamide) in bell pepper samples by ultra-high-performance liquid chromatography coupled Orbitrap mass spectrometry (UHPLC-Orbitrap-MS) was performed. A fast simple extraction procedure with acidified acetonitrile salts (magnesium sulfate sodium chloride) used. methodology validated, checking...
Acrylamide (AA) is a food contaminant with serious health effects. In this work, the addition of dietary fibre was proposed to mitigate AA in cookies and reduce bioaccesibility gastrointestinal trac. The analytical methodology applied for quantification based on solid-liquid extraction (SLE) followed by gas chromatography (GC) coupled mass spectrometry (MS). Preliminar results commercial fibres, such as k-carrageenan, arabinogalactan pectin, indicated that highest reduction could be obtained...
Increasing attention is currently being paid to the protective role of polyphenols in health and oxidative status fish. For this reason, potential use different natural sources such compounds, like wine by products, under study. One key step required gain a better understanding on biological roles for given species assess factors affecting their digestive bioaccessibility, great number studies based vitro digestion models. In present study bioavailability phenolic compounds bagasse lees was...
An orthogonal approach has been used to perform a metabolic profiling study of flonicamid in orange fruits.
