Honey is a food of nutritional, medicinal and commercial importance. The physicochemical characteristics, pollen spectrum and mineral composition of eighteen honey samples obtained from regions (Cachoeira, Coqueiros, Maragojipe and Santiago do Iguape) near the Paraguaçu River, Bahia, Brazil were evaluated. Botanical families Asteraceae, Leguminosae, Malvaceae, Myrtaceae and Palmae were most frequently found. Five samples had water contents above the maximum limit established by the Brazilian legislation (> 20%). The mineral composition was determined by ICP OES, after microwave digestion. Ca, K, Mg and Na were measured (mg Kg-1) in the range from: 18.85 to 79.61; 366.74 to 1214.98; 12.46 to 44.59 and 11.56 to 85.39, respectively. Cu, Fe, Mn and Zn had variable concentration ranges, between 0.05 and 6.13 mg Kg-1. Al, Ba, Cd, Co, Cr, Ni, Pb, Se and V showed values below the LOD. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) demonstrated that there are no similarities of mineral composition among honey samples.
蜂蜜是一种具有营养、药用和商业价值的食品。对从巴西巴伊亚州帕拉瓜苏河附近地区(卡舒埃拉、科凯罗斯、马拉戈吉佩和圣伊亚哥-杜伊瓜佩)采集的18个蜂蜜样本的理化特性、花粉谱和矿物质成分进行了评估。最常发现的植物科有菊科、豆科、锦葵科、桃金娘科和棕榈科。有5个样本的含水量高于巴西立法规定的上限(>20%)。经微波消解后,采用电感耦合等离子体发射光谱法(ICP OES)测定矿物质成分。测定了钙、钾、镁和钠的含量(mg Kg-1),范围分别为:18.85至79.61;366.74至1214.98;12.46至44.59和11.56至85.39。铜、铁、锰和锌的浓度范围各不相同,在0.05至6.13 mg Kg-1之间。铝、钡、镉、钴、铬、镍、铅、硒和钒的值低于检测限。主成分分析(PCA)和层次聚类分析(HCA)表明,蜂蜜样本之间的矿物质成分没有相似性。
