Determination of Ochratoxin A in apples contaminated with Aspergillus ochraceus by using a microfluidic competitive immunosensor with magnetic nanoparticles
(Royal Society of Chemistry, 2011-07-14)
Ochratoxin A (OTA) is a mycotoxin produced by filamentous fungi of the genus Aspergillus and Penicillium that presents carcinogenic, teratogenic and nephrotoxic properties. In this work, we have developed, characterized ...
Development of a novel UHPLC-MS/MS method for the determination of ochratoxin A in tea
(Elsevier, 2021-04)
The mycotoxin Ochratoxin A (OTA) is responsible for producing many effects on human and animal health. In this work, the evaluation of the presence of OTA in tea beverage samples consisted of extraction and preconcentration ...
A simple, rapid and novel method based on salting-out assisted liquid–liquid extraction for ochratoxin A determination in beer samples prior to ultra-high-performance liquid chromatography coupled to tandem mass spectrometry
(Taylor & Francis, 2018-08)
A novel, simple, easy and cheap sample treatment strategy based on salting-out assisted liquid-liquid extraction for ochratoxin A (OTA) ultra-trace analysis in beer samples using ultra-high-performance liquid chromatography-tandem ...
Determination of ochratoxin A in coffee and tea samples by coupling second-order multivariate calibration and fluorescence spectroscopy
(Elsevier Science, 2020-11-01)
A new method to quantify the mycotoxin ochratoxin A (OTA) in coffee and tea samples is proposed based on second-order multivariate calibration and excitation-emission fluorescence matrix (EEFM) data. Experimental conditions ...
Growth and ochratoxin A production by Aspergillus niger group strains in coffee beans in relation to environmental factors
(Wageningen Academic Publishers, 2010-02)
The effect of water activity (aW), temperature and their interactions on lag phase, mycelial growth rate and ochratoxin A (OTA) production at 7, 14 and 21 days of incubation of two OTA-producer strains belonging to Aspergillus ...
Lactobacillus reuteri CRL 1098 and Lactobacillus acidophilus CRL 1014 differently reduce in vitro immunotoxic effect induced by Ochratoxin A
(Pergamon-Elsevier Science Ltd, 2012-12-05)
Ochratoxin A (OTA) is a widespread mycotoxin contaminating several food products which causes detrimental health effects. The ability of Lactobacillus reuteri CRL 1098 and Lactobacillus acidophilus CRL 1014 to prevent OTA ...
Influence of planococcus ficus on aspergillus section nigri and ochratoxin a incidence in vineyards from argentina
(Wiley Blackwell Publishing, Inc, 2010-07-09)
Aim: The aim of this work was to evaluate the effect of Planococcus ficus infection in red wine grapes on Aspergillus section Nigri and ochratoxin A (OTA) contamination. Methods and Results: During 2006/2007 and 2008/2009 ...
Protective role of chlorogenic acid on DNA damage caused by ochratoxin A exposure
(Universidad Nacional de La Plata. Facultad de Ciencias Veterinarias, 2020-10)
Chlorogenic acid (ChlA) has shown short-term protective effects against the cytogenotoxiceffects of ochratoxin A (OTA). The present study evaluated the effect of oraladministration of ChlA in male Wistar rats exposed to ...
Influence of ochratoxin A on adaptation of Penicillium nordicum on a NaCl-rich dry-cured ham-based medium
(Elsevier Science, 2018-05)
Iberian dry-cured ham is an important meat product with high consumption worldwide. The special ecological conditions occurring throughout its ripening favour surface colonisation of filamentous fungi. Normally, moulds ...
Diversity of black Aspergilli isolated from raisins in Argentina: Polyphasic approach to species identification and development of SCAR markers for Aspergillus ibericus
(Elsevier Science, 2015-10)
Aspergillus section Nigri is a heterogeneous fungal group including some ochratoxin A producer species that usually contaminate raisins. The section contains the Series Carbonaria which includes the toxigenic species ...
