Determination of mycotoxins in foods: current state of analytical methods and limitations
The most crucial issues will be discussed in this review of classical and emerging analytical methods based on chromatographic or immunochemical techniques, the validation of official methods for enforcement, and the limitations and future prospects of the current methods. Expand
Analysis and migration of phthalates in infant food packed in recycled paperboard.
It is shown that paper does not provide an appropriate barrier against migration of semipolar compounds such as phthalates, and the air space itself otherwise effectively prevents migration of the less volatile phthalate esters under the applied conditions. Expand
In vitro glucuronidation kinetics of deoxynivalenol by human and animal microsomes and recombinant human UGT enzymes
None of the animal models is suitable for estimating the human DON metabolism with respect to the metabolite pattern and formation rate, and in vitro data indicated that DON phase II metabolism is strongly species dependent. Expand
Quantification of the Alternaria mycotoxin tenuazonic acid in beer
Abstract Tenuazonic acid (TA) is a major water soluble Alternaria mycotoxin. In the present work, a method for the quantification of TA in beer by liquid chromatography–ion-trap multistage massExpand
Voltage-dependent conductance of a single graphene nanoribbon.
It is shown that the conductance properties of a single molecule can be correlated with its electronic states and the importance of the edge states and a planar geometry. Expand
Investigation of the hepatic glucuronidation pattern of the Fusarium mycotoxin deoxynivalenol in various species.
It was shown that all animal and human liver microsomes led to the formation of up to three different mono-O-glucuronides with significant interspecies differences, and consistent in vitro data on DON glucuronidation are lacking. Expand
Degradation of the Alternaria mycotoxins alternariol, alternariol monomethyl ether, and altenuene upon bread baking.
The obtained quantitative data indicate that the Alternaria mycotoxins are barely degraded during wet baking, while significant degradation occurs upon dry baking, with the stability decreasing in the order alternariol monomethyl ether>alternariol>altenuene. Expand
Determination of the Alternaria mycotoxin tenuazonic acid in cereals by high-performance liquid chromatography-electrospray ionization ion-trap multistage mass spectrometry after derivatization with
A novel approach for the detection of TA in cereals by liquid chromatography-ion-trap multistage mass spectrometry after derivatization with 2,4-dinitrophenylhydrazine is described. Expand
Pathways of propionate degradation by enriched methanogenic cultures.
Observations suggest that in the culture, propionate was degraded through a randomizing pathway. Expand
Germination induces the glucosylation of the Fusarium mycotoxin deoxynivalenol in various grains
The germination process has a major influence on the “masking” of DON, leading to high quantities of D3G that may be missed in common mycotoxin analyses. Expand
