Abstract

Sorghum (Sorghum bicolor L. Moench) is a major drought-tolerant cereal crop grown mainly in the semi-arid regions of the world. It is an important basic food cereal in these regions which encompasses most of the developing world in many parts of Africa and Asia. Therefore, sorghum is an important source of nutrients for millions of inhabitants in these regions. In light of this, the nutritional quality of sorghum and how this is assessed is of major research interest. Various assays have been used to determine the contents of macronutrients and micronutrients in sorghum including how digestible and bioaccessible these are. A wide range of indices of sorghum nutritional quality has been generated. Advances in analytical instrumentation have contributed significantly to enhancing the capacity of analysts and researchers to broaden the scope of assays for sorghum nutritional quality and also to improve their accuracy.
