Nutritional values

Sorghum bicolor is rich in minerals like phosphorus, potassium and zinc. The nutritional values of Sorghum bicolor are comparable to those of rice, corn and wheat. The energy value of 100 g Sorghum bicolor grains ranges from 296.1 to 356.0 kcal (de Morais Cardoso et al., 2017). The grains contain 60 – 75% carbohydrates, 8 – 13% protein and 4 – 6 % fat. Due to the high saccharose and glucose content (10 – 16%) in the stalk it can be used as an alternative to sugar cane (10 – 20%) (Volker2003). The low starch digestibility of sorghum is caused by the association between the starch granules with the proteins and tannins (de Morais Cardoso et al., 2017). The digestibility of the proteins is lower than those of wheat and corn (de Morais Cardoso et al., 2017). In contrast to the prolamins of wheat, rye and barley, the kafirins of sorghum do not provoke allergic reactions or autoimmune response in humans(de Morais Cardoso et al., 2017). Furthermore, the properties of sorghum inhibit the expression of toxic peptides related to gliadin, making sorghum bicolor a safe grain for consumption by people with celiac disease (de Morais Cardoso et al., 2017).
