Description |
Six foxtail varieties grown in India were studied for their antioxidants, nutrients and digestibility in whole, dehulled (10 and 17%) and hulls (10 and 17%) of the grain. Total antioxidant activity was estimated by three different assays viz., Ferric reducing antioxidant power (FRAP), DPPH radical scavenging activity (DRSA), and thiobarbituric acid reactive substances (TBARS). Selected proximates, dietary fiber and in-vitro protein digestibility and grain colour were also assessed. Among the six varieties, SiA-2593 had highest mean total phenolics (TP) (143.56±55μg PE/g), tannins (413.80±58 mg/100g), FRAP (1477.83±26 μmol/g), DRSA (81.53±6.9%) and lowest TBARS (688.04±39%) followed by SiA-2644. Highest mean protein (11.33), dietary fiber (8.17) was found in SiA-2593 and higher fat content in SiA-326. Maximum in-vitro protein digestibility (IVPD) was observed in SiA-3088 and least was found in SiA-2593. Dehulling of the grain reduced TP by 24.64 and 43.11%, tannins by 16.13% and 29.61%, FRAP by 12.09% and 18.81%, DRSA by 4.07% and 14.76% and increase of TBARS by 45.29 and 58.21% at 10 and 17% dehulling. Dehulling also reduced moisture content, fat, dietary fiber and increased protein and protein digestibility. The hulls obtained after dehulling had higher percentage of TP, tannins, antioxidant activity (higher FRAP and DRSA and lower TBARS value), fat and dietary fiber, a* value of colour and lower percentage of protein, IVPD, L* and b* values of colour. A good positive correlation was observed between FRAP and Tannin (r=0.90, P |
