This study aimed to investigate the prevalence of aflatoxin B1 (AFB1) in four kinds of fermented soybean-related products used as traditional Chinese food: fermented soybean (FS), fermented qianzhang (FQ), fermented bean curd (FB) and fermented okara (FO). A total of 203 samples, comprising FS (40 samples), FQ (60), FB (41) and FO (62), were collected from free markets of agricultural food, convenience stores and supermarkets in Hubei province, China from November 2021 to January 2022.

This study proposes a novel qualitative and quantitative analysis method for wheat mildew degree and aflatoxin B1 (AFB1) by microwave detection technology combined with multi-task learning strategy. The team developed a miniaturized microwave detection device with double heterodyne mixing structure, and used this device to obtain the transmission indexes (amplitude and phase) of moldy wheat samples.

The safety problems associated with the occurrence of aflatoxin B1 (AFB1) in edible oils pose a serious threat to human health. In this research, the adsorbents of montmorillonite (MMT) modified with histidine under acidic conditions were prepared for AFB1 detoxification from peanut oil. To this goal, the characteristic of montmorillonite (MMT) modified with histidine at pH 4 (HMMT-4), 2 (HMMT-2), and 1 (HMMT-1) were analyzed by SEM, nitrogen adsorption-desorption, XRD, FT-IR, and TGA.

Tibetan kefir grains (TKG) are microbial symbiotic starters used in various fermented foods. Recent studies have focused on removing toxin contaminants from food using TKG.

The purpose of this study was to predict the optimal storage conditions for inhibiting aflatoxin production in upland rice seeds inoculated with Aspergillus flavus. The effects of storage conditions including moisture (A), temperature (B) and incubation time (C) on aflatoxin (AFG1, AFG2, AFB1, AFB2 and AFTOT) production in upland rice seed after inoculation of A.

Deoxynivalenol (DON) is a mycotoxin mainly produced by Fusarium graminearum and Fusarium culmorum and is commonly found in cereals such as wheat, barley, oats, and their derivatives. Scientists have been working on different strategies for DON detoxification, with biological detoxification being an approach with growing interest.

Aflatoxin B1 (AFB1) is an important cause of human liver cancer. This study proposes a quantitative detection method for the AFB1 in corn based on Fourier transform near-infrared (FT-NIR) spectroscopy technology.

Aspergillus flavus (A. flavus) is one pathogenic fungus that severely endangers human health and food safety. In our previous work, paeonol, a natural active compound from Paeonia. spp can inhibit the growth of A. flavus, and the mode of action is involved with targeting cell walls and cell membranes.

Zearalenone (ZEN) is an estrogen-like mycotoxin posing a great threat to human and animal health. The present study showed that the induction of spore CotA laccase production of Bacillus licheniformis by ions Mn2+ and Cu2+ promoted the ZEN-degrading ability of the strain.

Aflatoxin B1 (AFB1) is a toxin that is widely present in food and feed and poses a serious threat to the health of humans and livestock. In this work, we proposed the quantitative detection method of AFB1 contamination using a simple, sensitive, and specific colorimetric immunoassay based on gold nanoparticles labeled with glucose oxidase (GOx)/rabbit anti-mouse immunoglobulin G.

This study investigated the content of deoxynivalenol (DON), sugars, proteins, phenolics, amino acids, the antioxidant capacity and antioxidant enzymes activities of Fusarium naturally contaminated wheat (FCW) during soaking and germination.

Patulin (PAT) is a common toxin in fruit juice, and adsorption is the most commonly used patulin removal method. The safety, adsorption capacity, and separation capacity of the adsorbent are the most important considerations. As a low-cost and biocompatible microbial material, bacterial cellulose gel membranes (BCMs) have many hydroxyl active sites that are readily modified, and BCMs are also stable, which facilitates their separation from aqueous solution.

The use of biological agents able to metabolize mycotoxins to non-toxic compounds is a strategy that has received growing interest. However, the high costs of laborious methods for identifying potential candidates are obstacles for new products development.

Ochratoxin A (OTA) is a major mycotoxin contaminant of cereals and grapes. Our previous study proved the ability of Cryptococcus podzolicus Y3 to degrade OTA. The main aim of the present study was to investigate the OTA degradation mechanism by C. podzolicus Y3 using Next-generation sequencing. The results that showed 427 and 100 genes were up- and down-regulated after OTA exposure, respectively.
