Characterization of Argentinian Honeys Based on their Sugar Profiles and Quality Parameters

The honeys from the Argentinian provinces of Buenos Aires, La Rioja,Catamarca and Misiones were characterised by the sugar profile (fructose, glucose,sucrose, turanose, maltose and erlose) and the physicochemical parameters (freeacidity, pH, electrical conductivity (EC), colour and contents of moisture, ash,total soluble solids and hydroxymethylfurfural (HMF)) used for honey qualitycontrol. Authentic and traceable honey samples (n = 572) collected along fiveharvests were analysed using the official analytical methods. All honeys met thespecifications of the national and/or international standards for the evaluatedparameters, which denoted the blossom origin of most honeys, and confirmedtheir high quality, good maturity and freshness. The influence of the flora andthe pedoclimatic conditions of each phytogeographical region on the physicaland chemical properties of honey allowed its characterization. Thus, BuenosAires produced typical lighter honeys, and Misiones and Catamarca, darker ones.Buenos Aires honeys presented particular lower values of pH, EC, ash, HMF andmaltose, and higher concentrations of erlose. Misiones honeys exhibited highervalues of moisture, free acidity, EC and turanose amounts, and lower contentsof fructose, glucose and total soluble solids. La Rioja honeys showed higherpH and ºBrix values; and Catamarca honeys, higher sucrose contents. To theauthors? knowledge, the sugar profiles and several quality parameters of honeysfrom Misiones and Catamarca are here reported for the first time, as well as anyphysical and chemical data on La Rioja honeys.Fil: Poliero, Aimará Ayelen.

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

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.Fil: Poliero, Aimará Ayelen. Universidad Nacional de Mar del Plata.

Physicochemical Characterization Of Argentinian Honeys From The Phytogeographic Provinces Pampeana, Espinal And Monte Based On Their Sugar Profiles And Quality Parameters

The honeys from the Phytogeographic Provinces (PP) of the south of Buenos Aires province (Argentina) were characterised by the sugar composition and physicochemical parameters used for honey quality control. A large set (n=329) of traceable raw honey samples obtained from beekeepers were analysed and met the specifications of the national and/or international standards for the evaluated parameters, which denoted their blossom origin and confirmed their authenticity, good maturity and freshness. The influence of flora and the pedoclimatic conditions of each phytogeographical region, as well as their beekeeping practices, on the physical and chemical properties of honey allowed its characterization. Thus, the honeys from the southeast of Buenos Aires province were characterized by higher contents of moisture, fructose, maltose, erlose, hydroxymethylfurfural (HMF) and ash, pH and electrical conductivity (EC) and slightly lighter colours; while southwest honeys showed higher free acidities, sucrose content and ºBrix values. Honeys from the PP Espinal exhibited characteristic lower contents of fructose, HMF and ash and EC values, and larger amounts of sucrose. Honeys from the PP Monte presented typical lower moisture contents and slightly darker colours. Honeys from the PP Pampeana were typified by higher amounts of fructose
