Studies are scarce on the nutritional and phytochemical composition of wild edible Mediterranean plants after culinary processing. This work provides the nutritional composition after culinary treatment (including dietary fiber and mineral composition) and bioactive compounds (folates, vitamin C and organic acids) of wild L., (Moench) Garcke. leaves, and wild L., Jacq., L., L. young shoots. Shoots better preserved their nutrients than leaves, due to their different tissue structure. Fresh and cooked wild greens present high dietary fiber values, and remained at remarkable levels after boiling. Na, K, Mg and Zn were lost in about 50% due to culinary processing, while Ca, Cu, Fe and Mn were more stable. Boiled leaves of remained as a good Mn source. A portion of 100 g of most of the cooked analyzed species could cover a relevant percentage of the daily requirement of folates ( and providing more than 80%) and vitamin C ( and providing more than 35%).
关于烹饪加工后野生可食用地中海植物的营养和植物化学成分的研究很少。这项工作提供了烹饪处理后的营养成分(包括膳食纤维和矿物质成分)以及野生酸模叶蓼(Polygonum lapathifolium L.)、皱叶酸模(Rumex crispus L.)、小酸模(Rumex acetosella L.)嫩梢的生物活性化合物(叶酸、维生素C和有机酸)。由于组织结构不同,嫩梢比叶子更好地保留了它们的营养成分。新鲜和煮熟的野生蔬菜膳食纤维含量很高,煮沸后仍保持在显著水平。由于烹饪加工,钠、钾、镁和锌损失了约50%,而钙、铜、铁和锰则更稳定。酸模叶蓼煮熟的叶子仍然是锰的良好来源。100克大部分经分析的煮熟物种可以满足相当比例的叶酸每日需求量(酸模叶蓼和皱叶酸模提供超过80%)和维生素C每日需求量(酸模叶蓼和皱叶酸模提供超过35%)。
