Modified mycotoxins: An updated review on their formation, detection, occurrence, and toxic effects.

Food and Chemical Toxicology, 2018
Modified mycotoxins are metabolites that normally remain undetected during the testing for parent mycotoxin. These modified forms of mycotoxins can be produced by fungi or generated as part of the defense mechanism of the infected plant. In some cases, they are formed during food processing.

Occurrence of modified mycotoxins in Latin America: an up-to-date review.

Mycotoxin Research
The Latin America region has a considerable extent of varied climate conditions: from tropical, subtropical, and warm temperate to temperate. Among the surface territory, different agricultural products are produced, making them an important food source for human consumption.

Intestinal Metabolism of α- and β-glucosylated Modified Mycotoxins T-2 and HT-2 toxin in the Pig Cecum Model.

Journal of Agricultural and Food Chemistry, 2020
The type A trichothecene mycotoxins T-2 and HT 2 toxin are fungal secondary metabolites produced by Fusarium fungi which contaminate food and feed worldwide. Especially due to the high toxicity of T 2 toxin and their occurrence together with glucosylated

Use of cyclodextrins as modifiers of fluorescence in the detection of mycotoxins

Food Additives & Contaminants: Part A, 2008
Cyclodextrins, cyclic oligosaccharides composed of amylose subunits, are known to interact with mycotoxins. The interactions may be useful to analytical chemists by altering the properties of the mycotoxin of interest, namely the chromatographic properties, electrophoretic properties, fluorescence, or absorption of these fungal metabolites.

Surfactant modified zeolites––new efficient adsorbents for mycotoxins

Microporous and Mesoporous Materials, 2003
The in vitro mycotoxins adsorption by natural clinoptilolite––heulandite rich tuff modified with different amounts of octadecyldimethyl benzyl ammonium chloride (Do) and dioctadecyldimethyl ammonium chloride (Pr) was investigated. Two methods of preparation of the organo-zeolites (OZs) were used––wet process (activation in suspension) and dry process ...

Evaluation of a modified QuEChERS method for analysis of mycotoxins in rice

Food Chemistry, 2014
A simple and efficient QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) sample preparation method was modified to provide good analytical results for 14 mycotoxins in rice. The method involved mixing sample with acidified aqueous acetonitrile, followed by salt-out liquid partitioning using MgSO4, NaCl, and citrate buffer salts.

Growth of fungi and mycotoxin production on cheese under modified atmospheres

International Journal of Food Microbiology, 2001
The use of modified atmospheres to prevent fungal growth and mycotoxin production in cheese was evaluated. Eight fungal species: Mucor plumbeus, Fusarium oxysporum, Byssochlamys fulva, B. nivea, Penicillium commune, P. roqueforti, Aspergillus flatus and Eurotium chevalieri were inoculated onto cheese and incubated under conditions of decreasing ...

Highly Sensitive Simultaneous Detection of Multiple Mycotoxins Using a Protein Microarray on a TiO2-Modified Porous Silicon Surface.

Journal of Agricultural and Food Chemistry, 2020
A new protein microarray method for multiplex mycotoxin detection in parallel has been established on a stable TiO2-modified porous silicon (PSi) surface. A typical competitive immunoassay microarray protocol has been developed for simultaneous detection

Efficient Adsorption of the Mycotoxins Zearalenone and T‐2 Toxin on a Modified Yeast Glucan

Journal of Environmental Science and Health, Part B, 2003
1,3-Beta-D-glucan derived from baker's yeast was chemically modified in two steps yielding crosslinked carboxymethyl glucan as the sodium salt (2). After cation exchange with hexadecyltrimethylammonium chloride, a hydrophobic adsorbent (3) was obtained which showed an excellent binding of the estrogenic mycotoxin zearalenone with a maximum adsorption ...
