Sažetak
Among health-beneficial phytochemicals present in whole cereal grains phenolic compounds are the major ones because of their strong antioxidant properties. Eleven wheat bread genotypes (Triticum aestivum L.) grown at the Agricultural Institute Osijek during the 2013 and 2014 years were evaluated for total phenolic contents (TPC) and their antioxidant activity (AOA). TPC was determined by Folin-Ciocalteu method and AOA was evaluated using DPPH scavenging capacity. All the assays were done in triplicate from two separate extractions. Considerably variation of TPC within bread genotypes and years were found. TPC value was ranged between 0.573 mg GAE/gdw (Leuta 2014) to 1.153 mg GAE/gdw (Apache 2013). AOA was calculated as DPPH percentage discoloration and ranged between 12.101% (Srpanjka 2014) and 21.557% (Vulkan 2013). Consideration of TPC and AOC mean values, genotypes Apache, Vulkan and Antonija showed the highest TPC, whereas the highest AOA were found in genotypes Vulkan, Leuta and Antonija. Genotypes Srpanjka and Divana showed the lowest antioxidant properties based on TPC and AOA mean values. The obtained differences among genotypes indicate that through the breeding programmes more attention should be given to the development of new wheat lines with improved health beneficial properties.
