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 ...

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.

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 ...

Research progress on the raw and modified montmorillonites as adsorbents for mycotoxins: A review

Applied Clay Science, 2018
Abstract Mycotoxin, as one of the most common pollutants in animal feeds, is harmful and widespread, which has severely restricted the healthy development of livestock and feed industries. Therefore, to remove mycotoxins from animal feeds is becoming an intractable problem. Currently, naturally occurred clay minerals, especially montmorillonite (Mt),

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.

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.

Modified Fusarium mycotoxins unmasked: From occurrence in cereals to animal and human excretion

Food and Chemical Toxicology, 2015
Modified mycotoxins formed by plants, fungi and during some food processing steps may remain undetected by analytical methods, potentially causing underestimation of mycotoxin exposure and risk. Furthermore, due to altered physico-chemical characteristics of modified mycotoxins, these compounds might have different gastro-intestinal absorption compared

Selectivity of commercial immunoaffinity columns for modified forms of the mycotoxin 4-deoxynivalenol (DON)

Journal of Chromatography B, 2017
Commercial immunoaffinity columns (IACs) are today available for all major mycotoxins. However, manufacturers give usually no or very limited information on the epitope, i.e. the specific part of the toxin molecule that binds to the antibody. 4-Deoxynivalenol (DON) is a trichothecene mycotoxin that is produced by plant pathogenic field fungi and is ...

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 ...
