Honey composition and color depend greatly on the botanical and geographical origin. Water content, water activity and color of 50 declared acacia samples, collected from three different geographical zones of Romania, together with chromatographic determination of sugar spectrum were analyzed. A number of 79 volatile compounds from the classes of: Alcohols, aldehydes, esters, ketones, sulphur compounds, aliphatic hydrocarbons, nitrogen compounds, carboxylic acids, aromatic acids and ethers were identified by solid-phase micro-extraction and gas-chromatography mass spectrometry. The overall volatile profile and sugar spectrum of the investigated honey samples allow the differentiation of geographical origin for the acacia honey samples subjected to analysis. The statistical models of the chromatic determination, physicochemical parameters and volatile profile was optimal to characterize the honey samples and group them into three geographical origins, even they belong to the same botanical origin.
蜂蜜的成分和颜色在很大程度上取决于植物来源和地理来源。对从罗马尼亚三个不同地理区域采集的50个标明为刺槐蜜的样本进行了水分含量、水分活度和颜色分析，并对糖谱进行了色谱测定。通过固相微萃取和气相色谱-质谱联用技术鉴定出了79种挥发性化合物，这些化合物分属于醇类、醛类、酯类、酮类、硫化合物、脂肪烃类、含氮化合物、羧酸类、芳香酸类和醚类。所研究蜂蜜样本的总体挥发性特征和糖谱能够区分所分析的刺槐蜜样本的地理来源。颜色测定、理化参数和挥发性特征的统计模型对于表征蜂蜜样本并将它们分为三个地理来源最为适用，即便它们属于同一植物来源。
