Sorghum is grown around the world under diverse environmental conditions. Combined with the high degree of genetic diversity present in sorghum, this can result in substantial variability in grain composition and grain quality. While similar to other cereal grains such as maize and millets in some aspects, sorghum has many unique compositional traits which impact grain quality and utilization. This chapter reviews the composition of sorghum grain, including its physical structure, composition of bio-macromolecules and micronutrients. This chapter also includes a summary of research showing how various factors can impact sorghum grain composition.
