Two einkorn wheat, one barley, three optional winter cultivation wheat and five winter cultivation wheat samples harvested in Hungary in 2011, and their malts were evaluated for their DPPH radical and ABTS radical cation scavenging activity, ferric reduction capacity (FRAP) and total phenolic content (TPC). All einkorn and barley samples exhibited significant antioxidant activities determined by DPPH and ABTS radical scavenging activities. The einkorn samples show higher polyphenol content than the other wheat samples. In all cases the barley sample had the highest antioxidant potential and polyphenol content. The einkorn malts had high DPPH and ABTS radical cation scavenging activities, but the phenolic content was lower against wheat samples. There was significant difference between the antioxidant potential of optional and winter cultivation wheat samples except on ABTS scavenging activities. Einkorn wheat is potentially a new raw material to produce organic beer that might have beneficial effects with its increased antioxidant potential.
2011年在匈牙利收获的两个单粒小麦、一个大麦、三个可选冬小麦品种和五个冬小麦样本，对其麦芽的二苯基苦味酰基自由基（DPPH）清除活性、阳离子自由基ABTS清除活性、铁还原能力（FRAP）和总酚含量（TPC）进行了评估。所有单粒小麦和大麦样本通过DPPH和ABTS自由基清除活性测定均表现出显著的抗氧化活性。单粒小麦样本的多酚含量高于其他小麦样本。在所有情况下，大麦样本具有最高的抗氧化潜力和多酚含量。单粒小麦麦芽具有较高的DPPH和ABTS阳离子自由基清除活性，但与小麦样本相比，其酚类含量较低。除ABTS清除活性外，可选冬小麦品种和冬小麦样本的抗氧化潜力存在显著差异。单粒小麦有可能成为生产有机啤酒的新原料，因其抗氧化潜力的增加可能具有有益效果。
