Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 3, 2025

Microbial contamination remains a vital challenge across the food production chain, particularly due to mycotoxins-secondary metabolites produced by several genera of fungi such as Aspergillus, Fusarium, Alternaria, and Penicillium. These toxins, including aflatoxins, fumonisins, ochratoxins, trichothecenes (nivalenol, deoxynivalenol, T2, HT-2). contaminants pose severe risks human animal health, with their potential produce variety different toxic effects. Notably, up 50% global cereal is affected mycotoxin contamination, leading significant economic losses. Current research focuses on innovative technologies mitigate mycotoxins, cold atmospheric pressure plasma emerging promising decontamination method. This systematic review aimed at describing recent advances in application for toxigenic mycotoxins. Cold offers sustainable cost effective solution preserve quality while inactivating degrading Through generation reactive oxygen nitrogen species, disrupts fungal cell integrity, hinders spore germination, inhibits toxin biosynthesis. Additionally, plasma-driven degradation mycotoxins involves structural modifications, breaking key molecular bonds that reduce toxicity.

Recent advances in the degradation efficacy and mechanisms of mycotoxins in food by atmospheric cold plasma

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 270, P. 115944 - 115944

Published: Jan. 1, 2024

Food contaminated by mycotoxins has become a worldwide public problem with political and economic implications. Although variety of traditional methods have been used to eliminate from agri-foods, the results somewhat less than satisfactory. As an emerging non-thermal processing technology, atmospheric cold plasma (ACP) great potential for food decontamination. Herein, this review mainly presents degradation efficiency ACP on in vitro agri-foods as well its possible mechanisms. Meanwhile, effects quality, factors affecting toxicity products are also discussed. According literatures, could efficiently degrade many (e.g., aflatoxin, deoxynivalenol, zearalenone, ochratoxin A, fumonisin, T-2 toxin) both various foods hazelnut, peanut, maize, rice, wheat, barley, oat flour, date palm fruit) little nutritional sensory properties food. The efficacy was dependent including treatment parameter, working gas, mycotoxin property, substrate. attributed reactive oxygen nitrogen species ACP, which can damage chemical bonds mycotoxins, consequently reducing mycotoxins.

Dielectric barrier discharge air plasma as a comprehensive disinfection approach to E. coli and S. aureus biofilm management

Physica Scripta, Journal Year: 2025, Volume and Issue: 100(2), P. 025015 - 025015

Published: Jan. 2, 2025

Abstract This study aimed to assess the potential of Dielectric Barrier Discharge (DBD) cold atmospheric air plasma for E. coli and S. aureus biofilm management. The bacterial biofilms were grown on stainless-steel coupons treated with 1 5 min. results indicate reduction up 4.3 log CFU ml −1 3.3 , respectively. optical emission spectroscopy (OES) shows a possible presence OH O species as well abundance N 2 + features in plasma. Furthermore, Fourier Transform Infrared Spectroscopy (FTIR) revealed changes wavelengths that are specific carbohydrates, lipids proteins when effect was also confirmed by x-ray photoelectron (XPS) carbon decreased after treatment whereas phosphorus potassium increased due release from destructed cell wall. confocal laser scanning microscopy (CLSM) removing surface, where this most predominant min treatment. All all, our demonstrates DBD can effectively reduce viability reactive nitrogen oxygen within phase. Moreover, applied resulted successful eradication surface coupons.
