QuEChERS extraction with HRMS and accurate mass for the analysis of T-2 and HT-2 in cereals . Even in the absence of known mycotoxins, they might still occur in conjugated form and be undetected by targeted detection techniques. Soluble
Signal suppression/ enhancement (SSE) effect of 13 mycotoxins in 5 types of matrices. Five levels (1.325, 2.65, 13.25, 26.5, and 53 ng/mL) of standard solutions for each toxin were prepared by
26/4/2013 2.3. Determination of (masked) mycotoxin concentrations in foodstuffs Bread, popcorn, oatmeal and breakfast cereals were pulverized with the Moulinette 320-grinder (Moulinex, Barcelona, Spain). A cleaning and decontamination routine of the equipment was ®
Although not so toxic as other mycotoxins, it exhibits both chronic and acute toxicity, and therefore methods for its fast and accurate on-site determination are highly desirable. In the current work, we employ an optical immunosensor based on White Light Reflectance Spectroscopy (WLRS) for the fast and sensitive immunochemical label-free determination of DON in wheat and maize samples.
1/5/2020 Background Mycotoxins are natural contaminants produced by fungal species that colonize and contaminate crops, in special cereals, either in the field or in post-harvest commodities. Maize (Zea mays L.) is one of the most valuable crops worldwide, and it is prone to be infected by mycotoxigenic fungi with severe impacts mostly affecting farmers and livestock workers.
15/6/2018 1. Introduction Mycotoxins are a group of toxic compounds produced as secondary metabolites by certain fungi of the genus Aspergillus, Penicillium, Fusarium, Alternaria, and Claviceps that grow under different climate conditions and have been reported in several food matrices like cereals, peanuts, meat, eggs, milk, and fruits [1,2].
simultaneous quantitative determination in cereals of the Fusarium mycotoxins HT-2 toxin, T-2 toxin, deoxynivalenol, nivalenolandzearalenone,aswellasthemodifiedmetabolites 3-acetyl-deoxynivalenol,α-zearalenol, β-zearalenol, deoxynivalenol-3-glucoside, HT-2-3
A reliable and sensitive liquid chromatography-tandem mass spectrometric method was developed for the simultaneous quantitative determination in cereals of the Fusarium mycotoxins HT-2 toxin, T-2 toxin, deoxynivalenol, nivalenol and zearalenone, as well as the modified metabolites 3-acetyl-deoxynivalenol, α-zearalenol, β-zearalenol, deoxynivalenol-3-glucoside, HT-2-3-glucoside, nivalenol-3
11/12/2015 Mycotoxins are a problematic and toxic group of small organic molecules that are produced as secondary metabolites by several fungal species that colonise crops. They lead to contamination at both the field and postharvest stages of food production with a considerable range of foodstuffs affected, from coffee and cereals, to dried fruit and spices.
For screening of representative samples on mycotoxins testing was used immunochemical method of analyses ELISA (enzyme-linked immunosorbent assay), including samples preparation and data calculation for OTA and T-2 toxin determination in cereals in
