Bulgur has been one of the most important traditional Durum wheat products in Turkey and Middle Eastern countries for ages. The objective of this study was to reveal the composition of some healthy components of industrial bulgur samples produced in Turkey. Total starch, resistant starch, dietary fibre and total phenolic contents and their high-performance liquid chromatography (HPLC) profile and antioxidant capacity of bulgur samples using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging activity methods were investigated. The results showed that total dietary fibre ranged between 5.8 ± 0.7 and 8.2 ± 0.7% and resistant starch between 2.1 ± 0.2 and 2.8 ± 0.2%. Moreover, phenolic content with an average of 59.5 ± 5.2 mg Gallic acid/100 g dry matter and a moderate level of antioxidant capacity with an average of 22.2 ± 2.4% DPPH scavenging activity and 563.3 ± 60.7 μmol Trolox Equivalent Antioxidant Capacity/100 g dry matter of ABTS scavenging activity add value to the health benefits of bulgur product.
古麦（Bulgur）是土耳其和中东国家的一种重要传统硬质小麦产品，已有数百年的历史。本研究的目的是揭示土耳其生产的工业古麦样品中一些健康成分的组成。采用 2,2-二苯基-1-苦基肼（DPPH）和 2,2'-联氮-双（3-乙基苯并噻唑啉-6-磺酸）（ABTS）自由基清除活性法测定了古麦样品的总淀粉、抗性淀粉、膳食纤维和总酚含量及其高效液相色谱（HPLC）图谱和抗氧化能力。结果表明，总膳食纤维含量在 5.8±0.7%至 8.2±0.7%之间，抗性淀粉含量在 2.1±0.2%至 2.8±0.2%之间。此外，古麦产品的酚类含量平均为 59.5±5.2mg 没食子酸/100g 干物质，具有中等水平的抗氧化能力，平均 DPPH 清除活性为 22.2±2.4%，ABTS 清除活性为 563.3±60.7μmol Trolox 当量抗氧化能力/100g 干物质，为古麦产品的健康益处增添了价值。
