The aim of this work was to evaluate the quality of 16 honey samples from Castelo Branco region (Portugal). Twelve are monofloral from and . The mean values obtained for physicochemical parameters were: 3.82 pH; 16.80% moisture; 81.6°Brix; 0.21% ash; 357.6 μS cm electrical conductivity; 33.7 meq/kg free acidity; 5.7 meq/kg lactonic acidity; 39.3 meq/kg total acidity; 9.11 mg/kg HMF; 21.3 IN invertase and 9.0° Gothe for diastase activities. The results indicate a good quality, adequate processing, good maturity and freshness of honey. Additionally, the determination of mineral contents revealed that the K was the major element. Mean values obtained were (mg/kg): Ca, 28.36; K, 701.87; Mg, 74.00; Na, 31.04; Fe, 097; Cu, 0.65; Zn, 1.23; Mn, 2.78 and P, 48.80. Among the overall determined parameters, CB2 stands out by its high values in minerals, pH, moisture, ash, electrical conductivity and enzyme activity.
这项工作的目的是评估来自葡萄牙卡斯特洛布兰科地区的16个蜂蜜样本的质量。其中12个是来自[具体来源1]和[具体来源2]的单花蜂蜜。获得的物理化学参数平均值如下：pH值为3.82；水分含量为16.80%；糖度为81.6°Brix；灰分含量为0.21%；电导率为357.6 μS/cm；游离酸度为33.7 meq/kg；内酯酸度为5.7 meq/kg；总酸度为39.3 meq/kg；羟甲基糠醛含量为9.11 mg/kg；转化酶活性为21.3 IN；淀粉酶活性为9.0°Gothe。结果表明这些蜂蜜质量良好、加工得当、成熟度和新鲜度适宜。此外，矿物质含量的测定显示钾是主要元素。获得的平均值（mg/kg）如下：钙，28.36；钾，701.87；镁，74.00；钠，31.04；铁，0.97；铜，0.65；锌，1.23；锰，2.78；磷，48.80。在所有测定参数中，CB2在矿物质、pH值、水分、灰分、电导率和酶活性方面的值较高，表现突出。
