Bread wheat is a staple food crop that is consumed worldwide. In this study, using widely targeted LC-MS/MS, we conducted a high-throughput metabolomic analysis and determined the contents and spatial distribution of metabolites in pearled fractions of the dried kernels of six representative bread wheat varieties cultivated in China. Our aim was to explore the cultivars and pearling fractions with a view toward developing functional food products. We accordingly identified notable differences in the nutrient and bioactive metabolomes, and established that the pearling fractions of each cultivar had distinct metabolic profiles. Flavonoids varied the most amongst the cultivars and were found in higher concentration in the outer layers of the grain, but only at low concentrations in the kernel. Data from this study add further evidence of benefits of whole grain wheat consumption but, specifically, medium-gluten and pigmented wheat offer other nutrient and bioactive benefits whole grain products.
面包小麦是一种全球范围内消费的主食作物。在这项研究中，我们使用广泛靶向的 LC-MS/MS 进行了高通量代谢组学分析，测定了中国六个代表性面包小麦品种的干麦粒经碾磨抛光后的珍珠层部分的代谢物含量和空间分布。我们的目的是探索具有功能性食品产品开发潜力的品种和碾磨抛光部分。因此，我们鉴定出了在营养和生物活性代谢组方面具有显著差异的品种，并且发现每个品种的碾磨抛光部分都具有独特的代谢特征。类黄酮在品种之间变化最大，并且在谷物的外层含量较高，但在麦粒的内核中含量较低。本研究的数据进一步证明了全谷物小麦消费的益处，但具体而言，中筋和有色小麦提供了其他营养和生物活性益处，使全谷物产品更具优势。
