Abstract

ABSTRACT This article is the first contribution to the characterization of monofloral honeys from the Dry and Humid Chaco that combines palynological and physicochemical parameters. The study focuses on the most represented honeys. Physicochemical parameters such as color, electrical conductivity, moisture, acidity and pH were analyzed for a total of 116 honeys classified as monofloral by pollen analysis. All the parameters considered were within the accepted range. Color and electrical conductivity were the most distinctive features, as stressed by multivariate (cluster analysis (CA) and principal component analysis (PCA)) and correlation analysis. The darkest honeys (i.e. black, dark amber and amber) were those from Tessaria integrifolia, Schinopsis balansae, S. lorentzii and Baccharis–Eupatorium-type pollen, and the lightest honeys (i.e. light amber and extra light amber) were those from Cynophalla retusa, Eugenia uniflora, Copernicia alba, Prosopis alba and Helianthus annuus. Mean values for electrical conductivity ranged from 0.4 to 0.8mS cm–1, with the highest values detected in the darkest honeys, which are mainly produced in the Dry Chaco. The intense color of these honeys also suggests the presence of antioxidants. Thus, the color, electrical conductivity and antioxidant properties are important factors for future research to consider, to obtain a reliable authentication of the botanical and geographical features of these honeys.

阿根廷干湿查科地区单花蜂蜜的孢粉学和物理化学综述

摘要本文首次结合孢粉学和理化参数对干湿查科单花蜂蜜进行了表征。这项研究的重点是最具代表性的蜂蜜。对116种单花蜂蜜的颜色、电导率、水分、酸度和pH等理化参数进行了分析。所有考虑的参数都在可接受的范围内。多变量聚类分析(CA)、主成分分析(PCA)和相关分析强调，颜色和电导率是最显著的特征。颜色最深的蜂蜜(即黑色、深琥珀色和琥珀色)为产自荆芥(Tessaria integrifolia)、五味子(Schinopsis balansae)、S. lorentzii和bacchari - eupatorium型花粉的蜂蜜，颜色最浅的蜂蜜(即浅琥珀色和超浅琥珀色)为产自Cynophalla retusa、Eugenia uniflora、Copernicia alba、Prosopis alba和Helianthus annuus的蜂蜜。电导率的平均值在0.4 ~ 0.8mS cm-1之间，在颜色最深的蜂蜜中检测到的值最高，这些蜂蜜主要产自干查科。这些蜂蜜的强烈颜色也表明抗氧化剂的存在。因此，颜色、电导率和抗氧化性能是未来研究需要考虑的重要因素，以获得这些蜂蜜的植物和地理特征的可靠认证。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
