Summary The present work describes radiation‐induced effects during storage on total protein and amino acids composition of raw and processed flour of two pearl millet cultivars (Ashana and Dembi). The protein content of the whole raw flour was 14.46% and 13.38% for Ashana and Dembi cultivars, respectively. Dehulling of the grains reduced the protein content to 13.38% and 12.67% for the cultivars, respectively. Storage of the radiated whole and dehulled flour for 60 days slightly reduced the protein content even after cooking. The effect of radiation process in combination with the treatments applied to the grains and/or flour on amino acids contents was found to be varying between the cultivars. Most of the amino acids were stable against all treatments except leucine, glutamic acid and phenylalanine. Regardless of the storage period and processing method, amino acid contents of Ashana cultivar were increased after radiation process compared to that of Dembi cultivar.
