A nutritious diet is required to live a healthy and disease free life and to maintain it information about the biochemical and elemental composition of the diet is very crucial. For this, such techniques are required that have the potential of rapid characterization of biochemical and elements involving simple and easy procedural steps without the involvement of highly trained manpower. Therefore, the study aims to realize the potential of direct current arc optical emission spectroscopy as a digestion/extraction free, rapid and simultaneous multi-elemental detection tool to investigate the elemental composition of the staple food; semolina. The emission spectrum of the semolina has been recorded in the spectral region 350–900 nm by exciting the sample with the help of direct current source. The acquired spectrum shows persistent lines of the calcium, potassium, magnesium, manganese, iron, copper, sodium and chromium. The detected elemental profile of the semolina with direct current arc optical emission spectroscopy can add to the existing knowledge of nutrients in food.
