The nutritional characteristics of the Black Sea area (BSA) traditional foods are almost unknown, and they could be interesting sources of antioxidant compounds. In this study, carried out within the BaSeFood project, the in vitro total antioxidant capacity (TAC) and phenolic content of 39 BSA traditional foods were determined using different assays.
An ample range of TAC and phenolics content was detected in the examined foods that were ranked according to their scavenging activity expressed per weight unit and per serving size. Based on serving size, the highest TAC was in the order blueberries > nettle soup > sunflower seeds, and the fruits/fruit-based foods group was the one having the highest activity. Correlation analysis evidenced that the TAC is highly dependent on total phenolic content, while hydroxycinnamic acids and compounds having o-diphenolic structure did not show specific prominent effects. Finally, correlations between the two methods used for measuring the TAC suggest that they are both suitable in a wide range of foods.
Our data represent the first contribution to further research on the health effects of BSA traditional foods. This could enhance the interest of consumers, with potential benefits to stakeholders at all levels of the production chain.
黑海地区（BSA）传统食物的营养特性几乎不为人知，但它们可能是抗氧化化合物的有趣来源。在 BaSeFood 项目中进行的这项研究，使用不同的测定方法，测定了 39 种 BSA 传统食品的体外总抗氧化能力（TAC）和酚类含量。
在所检查的食品中，检测到了广泛的 TAC 和酚类含量，这些食品根据其在单位重量和每份中的清除活性进行了排序。按每份计，TAC 最高的顺序为蓝莓>荨麻汤>葵花籽，而水果/水果基食品组的活性最高。相关分析表明，TAC 高度依赖于总酚含量，而羟基肉桂酸和具有邻二酚结构的化合物并没有表现出特殊的突出作用。最后，用于测量 TAC 的两种方法之间的相关性表明，它们在广泛的食品中都适用。
我们的数据代表了对 BSA 传统食品健康影响的进一步研究的首次贡献。这可能会增加消费者的兴趣，对生产链各级利益相关者都有潜在的好处。
