For hundreds of years, people have used honey, and still are using it, as a natural sweetener and for its multiple health benefits. The quality of honey may be altered by several factors among which processing, storage conditions and falsification. The present study focusses mainly on the characterization of the physicochemical properties of nineteen Algerian honeys belonging to different localities and botanical origins in order to determine their quality and to detect any adulteration. For this purpose, water content, 5-hydroxymethylfurfural content, sugars content, pH, acidity, electrical conductivity and diastase activity were measured. Results indicate that all samples are in compliance with the values set by international standards for all the analysed parameters. In addition, relevant correlations were observed between the different analysed physicochemical properties of the selected honey samples from a part, and with bioclimate of geographical origins from another part. Besides, based on the examined physicochemical parameters, it appears that Z. lotus and Carduus sp. honey samples are characterized by high acidity and sucrose content while Eucalyptus sp. and multifloral honey samples are characterized by an elevated electrical conductivity, 5-hydroxymethylfurfural content and diastase activity. However, Citrus sp. honey samples are characterized mainly by higher content of glucose and fructose and equivalent humidity percentage. Overall, such physicochemical properties could be regarded as useful criterion for honey classification.

数百年来，人们一直在使用蜂蜜作为天然甜味剂，并仍在使用它，并具有多种健康益处。蜂蜜的质量可能会受到多种因素的影响，包括加工，储存条件和伪造。本研究主要集中在表征属于不同地区和植物来源的19种阿尔及利亚蜂蜜的理化特性，以确定其质量并检测任何掺假。为此，测量了水含量，5-羟甲基糠醛含量，糖含量，pH，酸度，电导率和淀粉酶活性。结果表明，所有样品均符合国际标准为所有分析参数设定的值。此外，在一部分选定蜂蜜样品的不同分析理化特性之间以及与另一部分地理起源的生物气候之间观察到相关的相关性。此外，根据检查的理化参数，看来Z.莲花和Carduus sp。蜂蜜样品的特点是酸度高，蔗糖含量高，而桉树属。和多花蜂蜜样品的特征在于电导率，5-羟甲基糠醛含量和淀粉酶活性的升高。但是，柑橘属。蜂蜜样品的主要特点是葡萄糖和果糖含量更高，当量湿度百分比更高。总的来说，这种理化特性可以被认为是蜂蜜分类的有用标准。
