Antifungal activities of thiosemicarbazones and semicarbazones against mycotoxigenic fungi

Ciência e Agrotecnologia, 2014
Mycotoxigenic fungi can compromise the quality of food, exposing human and animal health at risk. The antifungal activity of eight thiosemicarbazones (1-8) and nine semicarbazones (9-17) was evaluated against Aspergillus flavus, A. nomius, A.

Synthesis and Characterization of Hydrophobic Natural Deep Eutectic Solvent‐based Molecularly Imprinted Polymers for Selective Extraction of Aflatoxins and Determination With Liquid Chromatography‐Tandem Mass Spectrometry

SEPARATION SCIENCE PLUS, Volume 9, Issue 5, May 2026.
ABSTRACT A green approach to molecularly imprinted polymer synthesis is presented through the use of natural deep eutectic solvents. The polymer prepared for the selective adsorption of aflatoxins was synthesized via precipitation polymerization using 5,7‐dimethoxycoumarin as a template and a thymol/methacrylic acid deep eutectic solvent as both ...

Investigation of Potential Risks in Bio‐Based Food Contact Materials (FCMs) From Microbial Exploitation of Agricultural Wastes: Case Studies of Bacterial Cellulose and Nisin

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

Ustilago maydis Phosphatidic Acid and Phosphatidylserine‐Targeting Secreted Lipase Lip3 Is Involved in Pathogenesis

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
Ustilago maydis secreted lipase, Lip3 targets PA and PS and alkalinises the host apoplast, thus promoting virulence. Loss of Lip3 results in reduced apoplastic pH and decreased pathogenicity. ABSTRACT Lipases constitute important virulence factors. By targeting specific lipids involved in various cellular processes, lipases regulate growth, development,

Suppressed Production of Aflatoxin B1 by Aspergillus flavus and Aspergillus parasiticus on California In-hull Almonds and Hull Fragments

Journal of Food Protection
Almond hulls are economically important by-products marketed as dairy cattle feed in California. This study investigated the ability of Aspergillus flavus and Aspergillus parasiticus to grow and produce aflatoxins on almond hulls.

Development of a Novel, Simultaneous Determination Method for Heterocyclic Amines and Mycotoxins in Fried Food by UPLC–MS/MS Combined With QuEChERS

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
• A novel QuEChERS‐UPLC‐MS/MS method was successfully developed for the simultaneous determination of two β‐carboline heterocyclic amines and seven mycotoxins in fried foods. ABSTRACT Dietary exposure to both processing contaminants and natural toxins in fried foods poses a potential health risk, but analytical methods for their simultaneous monitoring

Occurrence of mycotoxins in milk and dairy products in Brazil: A review of recent data, regulatory aspects, preventive and decontamination strategies

International Journal of Dairy Technology, Volume 79, Issue 2, April–June 2026.
Mycotoxin data in Brazilian milk and dairy products over 20 years indicate aflatoxin M1 as the most frequent, although ochratoxin A, fumonisins and deoxynivalenol were also found in some studies. These data underscore the importance of control measures to reduce dietary mycotoxins in Brazilian dairy feed and avoid their residues in milk.
