Exploring The Potential Of Electromagnetic-Driven Energy Technologies In Preventing Microbial And Aflatoxin Contamination Of Grains, Abass A. Oduola
Graduate Theses and Dissertations
Electromagnetic-driven energy such as infrared (IR) technology holds great potential in deactivating Aspergillus flavus spores and prevents aflatoxin B1 (AFB1) contamination. Aflatoxins, highly toxic secondary metabolites primarily produced by Aspergillus species within the Flavi section (A. flavus, A. parasiticus, and A. nomius), pose substantial health risks to both humans and animals due to their significant toxicity and carcinogenic properties. Detecting and quantifying the presence and proliferation of these harmful fungi on food materials can be achieved by measuring the concentration of ergosterol. Ergosterol is a sterol compound produced in the cell membranes of fungi during their growth, providing …
