Sorghum (Sorghum bicolor) represents nowadays the main cereal in parts of Africa, Asia, India, Pakistan and China where it makes up much of the population’s diet. It is also used as animal feed to produce fodder.
Given its resistance to drought and heat, it is an important crop in arid regions of the world with advantages compared to corn, like using water more efficiently and producing more biomass.
The average starch content of sorghum grain is 64.8% (dry matter basis; DM); it also contains small amounts of free monosaccharides, sucrose and oligosaccharides. The amylose:amylopectin ratio is 20:80. Its fiber fraction (neutral detergent fiber 8% DM) has very little lignification (0.7% DM) and consists mainly of cellulose, hemicellulose and pentosanes.
