Analysis of Ochratoxin A in Wine by High-Resolution UHPLC-MS
Food Analytical Methods - Tập 5 - Trang 1506-1513 - 2012
Jianhui Li, Xin Liu, Shen Han, Jing Li, Qin Xu, Hong Xu, Yongwei Wang, Fei Liu, Zhaohui Zhang
A method for determination of ochratoxin A (OTA) in wines using a new-solid phase extraction clean-up procedure followed with ultra performance liquid chromatography (UHPLC)-Orbitrap MS based on two scan events (full-scan Fourier transform mass spectrometer [FTMS] and higher energy-induced collision dissociation[HCD] data-dependent MS/MS) in positive ionization mode has been developed. The limit o...... hiện toàn bộ
Trustworthy Identification of Resistance Biomarkers of Bacillus weihenstephanensis: Workflow of the Quality Assurance Procedure
Food Analytical Methods - Tập 11 Số 3 - Trang 921-932 - 2018
Noémie Desriac, Florence Postollec, Louis Coroller, Sonia Pavan, Jérôme Combrisson, Sylvie Hallier-Soulier, Danièle Sohier
Optimization of a HS-SPME-GC-MS Procedure for Beer Volatile Profiling Using Response Surface Methodology: Application to Follow Aroma Stability of Beers Under Different Storage Conditions
Food Analytical Methods - Tập 5 - Trang 1386-1397 - 2012
Juan José Rodriguez-Bencomo, Carolina Muñoz-González, Pedro José Martín-Álvarez, Elisabet Lázaro, Remedios Mancebo, Xavier Castañé, Maria Angeles Pozo-Bayón
The optimization of the main experimental variables, such as extraction temperature, volume of sample and the extraction time of an HS-SPME/GC-MS procedure, for profiling beer volatile analysis was evaluated using response surface methodology. A central composite circumscribed design was employed to study the effect of the experimental variables on the extraction of 28 representative volatile comp...... hiện toàn bộ

Magnetic Metal-Organic Framework/Graphene Oxide-Based Solid-Phase Extraction Combined with Spectrofluorimetry for the Determination of Enrofloxacin in Milk Sample
Food Analytical Methods - Tập 10 - Trang 4094-4103 - 2017
Zhaoqian Li, Mengyu Qi, Chunyan Tu, Weiping Wang, Jianrong Chen, Ai-Jun Wang
We have developed an analytical method for the extraction and determination of enrofloxacin in milk sample by magnetic solid-phase extraction with metal-organic framework/graphene oxide (Fe3O4/MIL-100(Fe)/GO) as a sorbent coupling to spectrofluorimetry. The prepared Fe3O4/MIL-100(Fe)/GO nanocomposite were characterized by scanning electron microscopy, FT-IR spectroscopy, x-ray diffraction, and vib...... hiện toàn bộ
Development of a Methodology for the Simultaneous Analysis of Multiclass Contaminants in Milk
Food Analytical Methods - Tập 14 - Trang 1075-1086 - 2021
Rodrigo Souza, Paula Fernández, Agustina Muela, María Verónica Cesio, Horacio Heinzen, Lucia Pareja
A simple methodology for the simultaneous determination of 67 pesticides, 25 veterinary drugs, and aflatoxin M1 in raw milk was developed and validated. After evaluating different combinations of sample preparation protocols, an extraction with acetonitrile:water (2:1) with QuEChERS citrate buffer salts and a combination of RP-C18 and anhydrous magnesium sulfate for the dispersive clean-up, using ...... hiện toàn bộ
Identification of Kiwifruits Treated with Exogenous Plant Growth Regulator Using Near-Infrared Hyperspectral Reflectance Imaging
Food Analytical Methods - Tập 8 - Trang 164-172 - 2014
Dayang Liu, Wenchuan Guo
The goal of this study was to explore the potential of using near-infrared (NIR) hyperspectral imaging in combination with multivariate analysis for the identification of kiwifruits treated with exogenous plant growth regulator (EPGR). One hundred twenty kiwifruits, variety ‘Xixuan,’ treated with EPGR and another 120 ‘Xixuan’ kiwifruits without EPGR (named as normal ones) were used in the study. H...... hiện toàn bộ
Determination of Benzene Series in Fish Based on Aqueous Two-Phase System for Samples Pretreatment
Food Analytical Methods - Tập 7 Số 7 - Trang 1513-1518 - 2014

Development and Validation of Analytical Method for Clenbuterol Chiral Determination in Animal Feed by Direct Liquid Chromatography
Food Analytical Methods - Tập 8 - Trang 2647-2659 - 2015
Noelia Rosales-Conrado, María Eugenia de León-González, Luis María Polo-Díez
A direct chiral liquid chromatography with UV detection method was developed and validated for enantiomeric determination of clenbuterol β2-agonist in feed samples for poultry. To obtain optimum chromatographic conditions for chiral separation, two commercially available columns packed with vancomycin and teicoplanin chiral stationary phase (150 × 2.1 mm i.d, 5 μm) were tested. Experimental design...... hiện toàn bộ
Development of a Dispersive Liquid–Liquid Microextraction Method for the Determination of α-Tocopherol in Pigmented Wheat by High-Performance Liquid Chromatography
Food Analytical Methods - Tập 7 - Trang 21-30 - 2013
Qilong Xie, Shuhui Liu, Yingying Fan, Xiaoke Zhang
A dispersive liquid–liquid microextraction (DLLME) method coupled to high-performance liquid chromatography was developed for the analysis of α-tocopherol in grain samples. The DLLME parameters including the type and volume of extractants, the volume of disperser and the addition of salt were examined. The optimized DLLME procedure consisted in the formation of a cloudy solution promoted by the fa...... hiện toàn bộ
