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
Quantification of the Food Dye Indigo Carmine in Candies Using Digital Image Analysis in a Polyurethane Foam Support
Food Analytical Methods - Tập 13 - Trang 962-969 - 2020
Igor Coreixas de Sá, Fernanda Neves Feiteira, Wagner Felippe Pacheco
The aim of this present work was to propose an alternative methodology to quantify the food dye indigo carmine in industrialized candies by the innovative technique of digital image analysis. To do so, the candy was solubilized in water and extracted to polyurethane foam, which is capable of selectively adsorbing the dye, removing interferents from the matrix. The foam was dried and glued on a she...... hiện toàn bộ

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
Development of a Protocol for Efficient DNA Extraction of Patulin-Producing Molds from Food for Sensitive Detection by PCR

Sensitive Simultaneous Determination of Synthetic Food Colorants in Preserved Fruit Samples by Capillary Electrophoresis with Contactless Conductivity Detection
Food Analytical Methods - Tập 11 Số 6 - Trang 1608-1618 - 2018
Yi, Jia, Zeng, Lewei, Wu, Qiyan, Yang, Lirong, Xie, Tianyao
A novel and sensitive analytical method, based on efficient sample clean-up and field-amplified sample injection (FASI) on-line preconcentration technique in capillary electrophoresis with contactless conductivity detection, for the simultaneous determination of synthetic food colorants in preserved fruit samples was developed. In order to remove the complex matrix interferences, i.e., large amoun...... 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
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
Chemiluminescent Enzyme Immunoassay for Rapid Detection of Three α-Cyano Pyrethroid Residues in Agricultural Products
Food Analytical Methods - Tập 9 - Trang 2896-2905 - 2016
Niusha Taheri, Meijing Lan, Peng Wei, Rui Liu, Wenjun Gui, Yirong Guo, Guonian Zhu
An indirect competitive chemiluminescent enzyme immunoassay (CLEIA) using a new broad-specific monoclonal antibody was developed for the determination of α-cyano pyrethroids. Under optimum conditions, this assay exhibited high sensitivities toward fenpropathrin, deltamethrin, and λ-cyhalothrin, with a wide detection range of 0.16 to 100 ng/mL and half-maximal inhibition concentration (IC50) of 1.9...... hiện toàn bộ
