Abstract:
... Zein, the plant protein, has received great attention in the last years. However, hidden zearalenone (ZEN), the zein-bound ZEN present in zein would have a great hazard to humans and animals. To date, the fates of hidden ZEN under different extraction methods of zein have not been clarified. In this study, the effect of zein extraction methods on conversion of free ZEN with hidden ZEN and its corr ...

Abstract:
... Zearalenone (ZEN) is harmful to animals and human beings, so it is very important to develop a rapid and sensitive method for the detection of ZEN. In this paper, we proposed a novel ZEN-monitoring method using two aptamers as recognition elements and EnGen LbaCas12a and Nt.AlwI nicking endonuclease as signal amplifiers. When ZEN was present, it bound to the aptamer Z0 and, Z1 was released into so ...

Mycotoxin contamination of corn has been considered a serious problem because it can accumulate in different organs or tissues via ingestion or skin contact and cause several health problems in humans. We have constructed a label-free, colorimetric, and fluorescence dual-channel sensing platform for the detection of zearalenone. Here, we demonstrate that plasmonic gold nanoparticles aggregates cou ...

Abstract:
... The productions of food, agricultural products and feed involve a variety processing conditions, which can affect the release/binding of zearalenone (ZEN) with macro-components in maize, resulting in the interconversion of hidden ZEN with free ZEN. This interconversion can cause the uncertainties and individual differences in the exposure assessment. To fully overcome this uncertainties of the pot ...

Abstract:
... Zearalenone (ZEN) and its derivatives is a major kind of mycotoxins that being commonly detected in contaminated grain products. ZEN lactone hydrolase (ZHD) can hydrolyze ZEN to produce non-toxic product, providing an environment-friendly way for ZENs detoxification. However, most of ZEN derivatives are more toxic, which leads to a high demand for the novel ZHD with high degradation activity towar ...

Abstract:
... Mycotoxigenic fungi can colonize small grain cereals causing severe yield losses and grain contaminations. Fusaria can be responsible for the contamination of wheat grains and derived products via several classes of mycotoxins, negatively impacting human and animal health. Among the strategies to control mycotoxins are analytical tools for their identification and quantification from field to food ...

The possibility of using the horseradish peroxidase (HRP)–phenol enzyme–substrate system in the development of an amperometric immunoenzyme sensor for the determination of the mycotoxin zearalenone (ZEA) was shown. New immunoenzyme amperometric sensors based on printed graphite electrodes, including those modified with a fullerene/gold nanoparticles and HRP composite, were proposed for the determi ...

Abstract:
... Mycotoxins are secondary fungal metabolites of high concern in the food and feed industry. Their presence in many cereal-based products has been numerously reported. Beer is the most consumed alcoholic beverage worldwide, and Fusarium mycotoxins originating from the malted and unmalted cereals might reach the final product. This review aims to describe the possible Fusarium fungi that could infect ...

Abstract:
... Fusarium meridionale and F. graminearum both cause Gibberella ear rot (GER) and Gibberella stalk rot (GSR) of maize in Brazil, but the former is much more common. Recent work with two isolates of each from maize suggested this dominance could be caused by greater aggressiveness and competitiveness of F. meridionale on maize. We evaluated pathogenicity and toxigenicity of 16 isolates of F. graminea ...
