Physicochemical Characterization and Sugar Profile of Argentinian Honeys from the Phytogeographic Provinces Paranaense and Pampeana in Misiones

Abstract

The characterization of honeys from the Biomes and vegetation units of the Phytogeographical Provinces (PP) located in the Province of Misiones (Argentina) was performed by analysis of sugar profile and physicochemical parameters (Free Acidity, pH, Electrical Conductivity (EC), colour and contents of moisture, ash, total soluble solids and hydroxymethylfurfural) used for quality control of honey. The honeys analysed were authentic and traceable, and met the specifications of the national and/or international standards for the evaluated parameters, denoting blossom origin and confirming high quality, maturity and freshness. The influence of biome and Vegetation Units (VU) on physical and chemical parameters of the studied honeys was defined regarding both flora and pedoclimatic conditions. Honeys from VU-27 presented significantly higher contents of fructose, ash and total soluble solids, pH and EC and lower moisture content than those from VU-3. To the authors’ best knowledge, sugar profiles, free acidity and contents of ash and total soluble solids in honeys from the different PPs, vegetation units and Biomes of Misiones are reported for the first time. This study contributes to the classification of honeys from Misiones, helping to increase added value and access new markets.
