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.

需要有营养的饮食才能过上健康无病的生活，并保持饮食的生化和元素组成信息非常重要。为此，需要此类技术具有快速表征生化和元素的潜力，涉及简单易行的程序步骤，而无需训练有素的人力参与。因此，本研究旨在实现直流电弧发射光谱作为一种无需消化/提取、快速、同步的多元素检测工具来研究主食元素组成的潜力；粗粮。通过在直流源的帮助下激发样品，粗面粉的发射光谱记录在 350-900 nm 的光谱区域。获得的光谱显示钙、钾、镁、锰、铁、铜、钠和铬的持久谱线。用直流弧光发射光谱法检测粗面粉的元素分布可以增加对食物中营养成分的现有知识。
