Improvement of dietary and ecological biodiversity, namely by exploring autochthonous varieties, is a key point to the construction of a more sustainable food system and planetary health. However, the environmental sustainability continues to face huge challenges, reflecting the importance of achieving a better understanding about the functional role of biodiversity in ecosystems. Thus, the main objective of this research is to contribute to the sustainable valorization of L. berries through a comprehensive approach to evaluate the effects of elderberry's cultivar, harvest year, and plantation field on the physicochemical berry composition. Moreover, the nutritional value of elderberry juice and respective dried pomace was determined. This complementary information is of huge utility for the rational and, as much as possible, integral use of elderberries. The harvest year, followed by field and the interaction of harvest × field, accounted for the highest impact on the berry's physicochemical parameters, indicating the importance of the combined impact of the macro- and mesoclimate conditions on plant metabolism. Elderberry juice and dried pomace are a good source of carbohydrates (ca. 12 and 82%, respectively) and have low amounts of fat (≤2.5%), making them low-energy foods. Dried pomace may also represent a potential alternative source of vegetal protein (ca. 6%).
改善饮食和生态生物多样性，即通过探索本地品种，是构建更可持续的食品系统和地球健康的关键。然而，环境可持续性仍面临巨大挑战，这反映出更好地理解生物多样性在生态系统中的功能作用的重要性。因此，本研究的主要目标是通过综合评估接骨木莓品种、收获年份和种植地对接骨木莓理化成分的影响，为接骨木莓的可持续增值做出贡献。此外，还测定了接骨木莓汁和相应干渣的营养价值。这些补充信息对于合理且尽可能全面地利用接骨木莓具有巨大的实用价值。收获年份，其次是种植地以及收获×种植地的相互作用，对接骨木莓的理化参数影响最大，这表明宏观和中观气候条件对植物代谢的综合影响的重要性。接骨木莓汁和干渣是碳水化合物的良好来源（分别约为12%和82%），脂肪含量低（≤2.5%），使其成为低能量食品。干渣也可能是植物蛋白的潜在替代来源（约6%）。
