Assessment of Bioactive Profile of Sorghum Brans under the Effect of Growing Conditions and Nitrogen Fertilization

Sorghum bicolor (L.) Moench is an increasingly important crop grown in many countries as a food source due to its excellent nutritional value, drought and pest resistance, gluten-free properties. In this study, the bioactive profiles antioxidant potentials of brans six sorghum varieties were evaluated using spectrophotometric methods. The effects weather environmental conditions different nitrogen nutrition also evaluated. bran red contained higher amount polyphenols tannins exhibited capacities than white varieties, with exception one genotype. highest total polyphenol contents measured samples from two (Zádor, Alföldi1) 1084.52 ± 57.92 mg 100 g−1 GAE 1802.51 121.13 values, respectively, while condensed tannin content varied between 0.50 47.79 brans. Red showed activities/capacities 70–281 µmol TE 71–145 for DPPH TEAC. Correlation analysis strong interaction DPPH, TEAC, amounts tannins, but not FRAP values. conclusion, red-colored are good polyphenols, seed color alone enough determine value genotype, greatly affect profile sorghum.
