Generally, heat and γ-irradiation techniques are used in the preservation of millets.Therefore, the effect of heat (150°C to 170°C for 90 s at 300 rpm) and γ-irradiation (1 kGy and 2.50 kGy) on fungal load, pasting, and rheological characteristics of three whole and dehulled millets (sorghum, foxtail millet, and pearl millet) was investigated during storage (90 days). The findings showed that the pasting (e.g., pasting temperature, peak viscosity, and peak temperature, etc.) and rheological (e.g., storage modulus, loss modulus, and yield point, etc.) properties decreased during 90 days of storage. The results indicated that the heat and γ-irradiation collectively reduced the fungal load (154 × 104 to 3.58 × 104 CFU/g) on the whole and dehulled millets. Therefore, the study concluded that the heat and γ-irradiation may improve the millets storability and seems to be a promising postharvest preservation method to reduce fungal incidences in millet-based products
