Aflatoxin M1 contamination in grated parmesan cheese marketed in Rio de Janeiro - Brazil BABT
Trombete,Felipe Machado; Castro,Izabela Miranda de; Teixeira,Alessandra da Silva; Saldanha,Tatiana; Fraga,Marcelo Elias.
This study aimed to determine the occurrence of AFM1 contamination in the samples of grated parmesan cheese marketed in the Metropolitan Region of Rio de Janeiro -Brazil. Thirty samples representing 10 major brands marketed in the region were analyzed by High Performance Liquid Chromatography with fluorescence detection (HPLC-FLD) after purification with immunoaffinity column. The method showed recovery values within the range of 70-90%, with RSD lower than 15% and limits of detection and quantification below the maximum level allowed by the European Commission for the presence of AFM1 in cheeses. The mycotoxin was identified in 18 (60%) of the grated cheese samples tested. The highest value corresponded to 0.69 ± 0.02 µg/kg and the mean for all the...

Comparison of High Performance Liquid Chromatography with Fluorescence Detector and with Tandem Mass Spectrometry methods for detection and quantification of Ochratoxin A in green and roasted coffee beans BABT
Bandeira,Raquel Duarte da Costa Cunha; Uekane,Thais Matsue; Cunha,Carolina Passos da; Rodrigues,Janaina Marques; la Cruz,Marcus Henrique Campino de; Godoy,Ronoel Luiz de Oliveira; Fioravante,Andreia de Lima.
Two analytical methods for the determination and confirmation of ochratoxin A (OTA) in green and roasted coffee samples were compared. Sample extraction and clean-up were based on liquid-liquid phase extraction and immunoaffinity column. The detection of OTA was carried out with the high performance liquid chromatography (HPLC) combined either with fluorescence detection (FLD), or positive electrospray ionization (ESI+) coupled with tandem mass spectrometry (MS-MS). The results obtained with the LC-ESI-MS/MS were specific and more sensitive, with the advantages in terms of unambiguous analyte identification, when compared with the HPLC-FLD.
