  "account": "Peanuts infected with aflatoxin B1 were irradiated using either gamma or electron beam sources at varying doses (0–10 kGy) to assess their impact on microbial populations, chemical properties, and safety. Both irradiation methods were successful in lowering AFB1 levels (529.40 ± 3.40 µg/kg) and microbial contamination, while gamma irradiation demonstrated more pronounced reductions (85.9% at 2 kGy, complete at 4 kGy) compared to electron beam (58.01% and 97.59% at 2 and 4 kGy, respectively). Gamma irradiation also inhibited Aspergillus flavus growth at 2 kGy. However, doses above 2 kGy, especially 10 kGy, led to increased malondialdehyde levels, indicating lipid oxidation that could compromise peanut quality and consumer acceptance, along with a darker appearance. Total soluble protein levels increased, and protein electrophoretic patterns changed at doses of ≥ 4 kGy. Although sensory analysis was not conducted, changes in volatile compounds and color indices were used as indicators of sensory quality. Notably, irradiation affected phytosterols, volatile compounds, fatty acid profiles, and certain unsaturated fatty acids at higher doses. The study suggests that gamma and electron-beam irradiation at 2 kGy can effectively enhance peanut safety without significantly compromising quality, but dosage optimization is necessary to balance efficacy and sensory attributes. Supported by NSTRI, AEOI, the study involved researchers from Amirkabir University of Technology and was conducted in compliance with local regulations.",
