Natural occurrence of Ochratoxin A in musts, wines and grape vine fruits from grapes harvested in Argentina
(2010-08)
In this study, ochratoxin A (OTA) occurrence in Argentinean musts, wines and dried vine fruits was evaluated, alongside with the performance of OchraStarTM columns for OTA extraction. In all the three matrices analyzed, ...
Prevention of ochratoxin a production by using food grade antioxidants
(Nova Science Publishers, 2015)
Ochratoxin A (OTA) is the second mycotoxin, followed by aflatoxins, of significance in several agricultural products. During the last decades, OTA has been receiving considerable attention worldwide because of its nephrotoxic, ...
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 ...
Biodiversity of Aspergillus section Nigri populations in Argentinian vineyards and ochratoxin A contamination
(2013-12)
Aspergillus section Nigri are described as the main source of ochratoxin A (OTA) contamination in grapes and wine worldwide. The knowledge of the factors affecting grape contamination by species included in this section ...
