Abstract Globally, aflatoxin contamination in maize remains a huge burden despite many interventions put place. The use of low-temperature plasma to decontaminate the is potential solution for ensuring safety and extended shelf life grain. This study optimized parameters investigated efficacy nitrogen (LTNP) destroying fungi reducing exposure aflatoxins naturally contaminated from an endemic region. generated 17 experimental runs using Response Surface Methodology (RSM) Box Behnken Design (BBD) with time, pressure, ionization density as independent variables. Quantitative assessment was conducted Monte Carlo simulations followed by sensitivity scenario analysis factors influencing best aflatoxin-reducing parameters. best-fitting RSM model, linear indicated that increased time but not pressure power led corresponding statistically significant decrease fungal load content. LTNP reduced levels below all main global regulatory limits. Numerical optimization percent reduction 1793.4 s, 0.98 pascal 189.8 W are required achieve optimal content 82.6% 96.9%. Exposure high especially populations lower body weight ρ = -0.46 between exposure. combinations achieved results comparable markedly less variation than existing practically used decontamination methods. Further studies during upscaling recommended, incorporating such temperature processing volume outcomes organoleptic, physical, chemical changes food matrices after treatment.
