Nowadays, there is a general concern regarding the increasing global talk about functional foods that respond to our demands and needs as consumers in order to maintain health and body weight through a correctly balanced diet. Cereals are key elements of nutrition and a healthy diet, and they also play a significant role in health promotion due to the useful nutrient content. Therefore, this work aims to identify barley and oat genotypes suitable for human nutrition and to achieve practical results for their widespread use in preventing or treating certain chronic diseases by analyzing the nutritional and physical properties of 52 genotypes of oat and barley conserved in Suceava Gene Bank, Romania. The first part of this manuscript is the presentation of these accessions and the evaluation of their most important properties. For oat and barley cultivars, detailed processing was carried out, involving the computation of variation amplitude, coefficients of correlation and cluster analyses, both for biochemical (protein, lysine and tryptophan contents) and physical (test weight and seed weight) properties. The results indicated high variability between oat and barley varieties. Thus, according to the results, the 26 varieties of oat exhibited almost double the content of lysine compared to barley seeds, while tryptophan had higher values in barley than in oat seeds. Overall, both species play an essential role in human nutrition, barley being important because of its high protein content and higher productivity compared to oats, which, although not as productive, have better quality seeds due to their higher lysine content. The results presented are not only of scientific interest but also have practical implications for agriculture, food safety, nutrition and human health. The documented information will facilitate new studies needed to contribute to improving human nutrition and health.
如今，全球对于功能性食品的讨论日益增多，这类食品旨在满足消费者维持健康体重的需求，通过合理均衡的饮食来实现。谷物是营养和健康饮食的关键要素，因其富含有益营养成分，在促进健康方面也发挥着重要作用。因此，本研究旨在通过分析罗马尼亚苏恰瓦基因库保存的52个燕麦和大麦基因型的营养及物理特性，鉴定适合人类营养的大麦和燕麦基因型，并取得其在预防或治疗某些慢性病方面广泛应用的实际成果。本论文的第一部分介绍了这些种质资源，并评估了它们最重要的特性。对于燕麦和大麦品种，进行了详细的分析，包括计算生化特性（蛋白质、赖氨酸和色氨酸含量）和物理特性（容重和种子重量）的变异幅度、相关系数以及聚类分析。结果表明燕麦和大麦品种间存在高度变异性。因此，根据结果，26个燕麦品种的赖氨酸含量几乎是大麦种子的两倍，而大麦种子中的色氨酸含量高于燕麦种子。总体而言，这两个物种在人类营养中都起着至关重要的作用，大麦因其高蛋白含量和比燕麦更高的产量而重要，燕麦虽然产量不高，但其种子因赖氨酸含量较高而品质更好。所呈现的结果不仅具有科学价值，对农业、食品安全、营养和人类健康也具有实际意义。记录的信息将有助于开展新的研究，以促进人类营养和健康的改善。
