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 SupportFood 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
Sensitive Simultaneous Determination of Synthetic Food Colorants in Preserved Fruit Samples by Capillary Electrophoresis with Contactless Conductivity DetectionFood 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 MilkFood 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
Chemiluminescent Enzyme Immunoassay for Rapid Detection of Three α-Cyano Pyrethroid Residues in Agricultural ProductsFood 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
