The present study evaluated the physicochemical characteristics and antioxidant activity of 13 commercial honeys from diverse floral origin, produced in Portugal. The values of electrical conductivity of cardoon and pennyroyal honeys were superior to the maximum limits defined by European legislation. Citrus, strawberry tree, and 1 sample of lavender honeys had values of diastase activity below those determined by European legislation. Strawberry tree, pennyroyal, and cardoon honeys had the highest amounts of potassium that coincided with the highest electrical conductivity. Strawberry tree honey was the most effective as antioxidant along with cardoon and heather honeys. This ability was strongly correlated with the amounts of phenols and flavonoids and not with the levels of vitamin C or proline.
本研究评估了 13 种来自不同花卉产地的商业蜂蜜的理化特性和抗氧化活性，这些蜂蜜均产自葡萄牙。款冬和薄荷蜂蜜的电导率值高于欧洲法规规定的最大值。柑橘、草莓树和薰衣草蜂蜜的酶活性值低于欧洲法规规定的值。草莓树、薄荷和款冬蜂蜜含有最高量的钾，这与最高的电导率相一致。草莓树蜂蜜是最有效的抗氧化剂，其次是款冬蜂蜜和石楠蜂蜜。这种能力与酚类和类黄酮的含量密切相关，而与维生素 C 或脯氨酸的水平无关。
