Occurrence of mycotoxins in selected foodstuffs

, 2011
This study summarizes the actual problematic of mycotoxins and provide the detail review concerning the mycotoxins occurrence in food and feed, whereas the most attention in this year is paid for mycotoxins, which are in the interest of European Food ...

Scientific Opinion on the risks for human and animal health related to the presence of modified forms of certain mycotoxins in food and feed

EFSA Journal, 2014
Following a request from the European Commission, the risks to human and animal health related to modified forms of the Fusarium toxins zearalenone, nivalenol, T‐2 and HT‐2 toxins and fumonisins were evaluated. Modified (often called “masked”) mycotoxins

Occurrence of the Ochratoxin A Degradation Product 2′R-Ochratoxin A in Coffee and Other Food: An Update

Toxins, 2019
Food raw materials can contain the mycotoxin ochratoxin A (OTA). Thermal processing of these materials may result in decreased OTA levels but also in the formation of the thermal isomerization product 2′R-ochratoxin A (2′R-OTA).

Development and Validation of an Ultra-High Performance Liquid Chromatography-Tandem Mass Spectrometry Method for Simultaneous Determination of Four Type B Trichothecenes and Masked Deoxynivalenol in Various Feed Products

Molecules, 2016
A reliable and sensitive analytical method was developed for simultaneous determination of deoxynivalenol(DON), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), fusarenon X (FUS-X), and masked deoxynivalenol (deoxynivalenol-3-glucoside,

Rapid enzymatic hydrolysis of masked deoxynivalenol and zearalenone prior to liquid chromatography mass spectrometry or immuniassay analysis

, 2014
Recently it has been shown that conjugates (‘masked mycotoxins’) may contribute to the total daily intake of hazardous mycotoxins. Therefore, there is an urgent need for rapid analysis methods that assess the level of both free and masked mycotoxins in ...

Occurrence and variation of Fusarium free and masked mycotoxins in maize from agriculture regions of South Africa

, 2019
PhD (Biological Sciences), North-West University, Mafikeng CampusIn the past years, it has become very clear that in mycotoxin-contaminated foodstuffs, many structurally related compounds generated from plant metabolism or during food processing can ...

Simultaneous determination of masked forms of deoxynivalenol and zearalenone after oral dosing in rats by LC-MS/MS

, 2012
In vivo metabolism of masked or conjugated mycotoxins is poorly documented as standards are not commercially available and indirect analysis using hydrolytic enzymes is difficult to validate and cumbersome.

Impact of Environmental Conditions on the Concentrations of Trichothecenes, Their Glucosides, and Emerging Fusarium Toxins in Naturally Contaminated, Irradiated, and Fusarium langsethiae Inoculated Oats

Toxins
Trichothecenes produced by Fusarium species are commonly detected in oats. However, the ratios of the concentrations of free trichothecenes and their conjugates and how they are impacted by different interacting environmental conditions are not well ...

Interactions of (1,3-dicarbonyl)-mycotoxins and metal ions

, 2015
Mycotoxins are secondary metabolites of fungi which have diverse detrimental effects on humans, animals and crops. Traceable worldwide in foods and animal feeds, these contaminants cause manifold diseases and extensive economic losses.

Conjugation of the Mycotoxins Alternariol and Alternariol Monomethyl Ether in Tobacco Suspension Cells

, 2015
The mycotoxins alternariol (AOH) and alternariol-9-O-methyl ether (AME) carry three and two phenolic hydroxyl groups, respectively, which makes them candidates for the formation of conjugated metabolites in plants.
