Linking Soil, Water, and Honey Composition To Assess the Geographical Origin of Argentinean Honey by Multielemental and Isotopic Analyses

Abstract

The objective of this research was to investigate the development of a reliable fingerprint from elemental and isotopic signatures of Argentinean honey to assess its geographical provenance. Honey, soil, and water from three regions (Córdoba, Buenos Aires, and Entre Rı́os) were collected. The multielemental composition was determined by ICP-MS. δ(13)C was measured by isotopic ratio mass spectrometry, whereas the (87)Sr/(86)Sr ratio was determined using thermal ionization mass spectrometry. The data were analyzed by chemometrics looking for the association between the elements, stable isotopes, and honey samples from the three studied areas. Honey samples were differentiated by classification trees and discriminant analysis using a combination of eight key variables (Rb, K/Rb, B, U, (87)Sr/(86)Sr, Na, La, and Zn) presenting differences among the studied regions. The application of canonical correlation analysis and generalized procrustes analysis showed 91.5% consensus between soil, water, and honey samples, in addition to clear differences between studied areas. To the authors' knowledge, this is the first report demonstrating the correspondence between soil, water, and honey samples using different statistical methods, showing that elemental and isotopic honey compositions are related to soil and water characteristics of the site of origin.

Antioxidant Activity, Total Phenolic Content, Individual Phenolics and Physicochemical Parameters Suitability for Romanian Honey Authentication

“…The chemical composition depends on the source of honey, which refers to the botanical and geographical origin, as well as the environmental conditions [12]. Monofloral honey is increasingly required on the market and it is necessary to be able to determine some parameters regarding the composition, organic acids compositions) was performed to authenticate the botanical origin of sunflower, raspberry, thyme, mint, rape and polyfloral honey from Romania.…”

Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case study on different grafting combinations

“…In this context, the knowledge of one or more chemistry relationships between the soil and the agricultural products is an important tool for the quality assessment of food (Baroni et al, 2015;Drivelos & Georgiou, 2012;Durante et al, 2016;Gonzalvez, Armenta, & de la Guardia, 2009;Luykx & van Ruth, 2008;Marchionni et al, 2016;Reid, O'Donnell, & Downey, 2006;Zhao et al, 2013). Among the different techniques and compounds, or class of compounds, used to evidence these relationships, undoubtedly ICP-MS and trace elements have been exploited (Durante et al, 2015;Luykx & van Ruth, 2008;Reid et al, 2006).…”

Classification of Honey from Its Bee Origin via Chemical Profiles and Mineral Content

“…Honey is usually named by its botanical and geographical origin. Efforts of identifying honey with botanical and geographical origin such as through its composition of carbohydrates (Cotte et al 2003;de la Fuente et al 2011), amino acids (Rebane and Herodes 2008), mineral and trace element (dos Santos et al 2008;Alda-Garcilope et al 2012), stable isotopes (Baroni et al 2015;Dinca et al 2015), phenolic compounds and physiochemical properties (Karabagias et al 2014;Popescu et al 2016;Zhao et al 2016) have been reported. As honey-making processes are highly related to enzymes added by the bees, it is envisaged that composition of honey is also affected by the types of bee that produce it.…”
