Sažetak
Phenolic contents and corresponding antioxidant activities were studied in covered and hull-less whole-grain flours of different barley varieties. Tested samples were collected from field trials at Agricultural Institute Osijek during the growing seasons 2012 and 2013. Barun, Bravo, Bingo, Premium, Vanessa, Tiffany, Maxim and Rex were the representative malting varieties, and GZ-179, GZ-184, GZ-186, GZ-189, GZ-190 and GZ-191 are experimental hull-less varieties. The total phenolic content, as measured according to Folin-Ciocalteu’s method, ranged from 1.30-1.78 mg GAE/gdw in 2012 and from 1.17-1.49 mg GAE/gdw in 2013. Antioxidant activity was evaluated as radical scavenging activity with DPPH reagent. The two year results show that hull-less barley GZ-186 was the variety with the highest antioxidant activity and the highest total phenolic content. According to the results from our present study, hull-less barley lines were found to have an average content of phenolics and antioxidant activity higher than malting varieties.
