Improving the nutritional quality of cereals and legumes by germination

Cereal and legume grains are germinated to improve their nutritional and sensory qualities. This study investigated the effect of germination on the physicochemical properties of some grains and legumes grown in Turkey. At the end of the germination for 48 h and 96 h at 24 ± 1 °C, carbohydrate, protein, lipid, dietary fibre, dry matter, ash, total phenolic content, antioxidant capacity and colour analyses of the germinated grains were determined. The results indicated that the germination process increased the phenolic content of all samples. The legume seeds' 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity significantly increased with germination. The germination process significantly decreased the total carbohydrate contents of the samples. A statistically significant decrease was found for the protein content of barley and corn, especially by 48 h of germination. The lipid content of cereal grains decreased as germination progressed. It might be recommended to improve the functional properties of cereals and legumes by germination and their use in the food industry.
