“…That is why some authors, have suggested the EC measurements as an indirect technique to determine the mineral content in some foods. 14,22 However, the correlations observed for the pairs: CE-Cu (r = 0.617)/ CE-Na (r = 0.184) and ash-Na (r = 0.666)/ash-Cu (r = 0.135) imply that the EC values depend not only on concentration but also are dependent on the mobility of ions present in the honey samples.…”

Moreover, reliable techniques for origin authentication are essential because official analysis of honey involves a series of several determinations of chemical and physical parameters that will be of little use for the geographical certification.…”

Neste trabalho, amostras de mel produzidas em três diferentes regiões climáticas do Sudoeste da Bahia, Brasil (semi-árido, Mata Atlântica e Zona de Transição Climática) foram caracterizadas com base nos teores de minerais, elementos traços, cinzas e condutividade elétrica. Os metais foram determinados por espectrometria de absorção atômica. Com a finalidade de avaliar as variáveis químicas capazes de promover uma caracterização do mel produzido em cada região, as técnicas de cluster e componentes principais (ACP) foram aplicadas nos resultados das análises. Com base nas análises de cluster e ACP, foi possível distinguir os diferentes grupos de amostras correspondentes às três origens geográficas dos méis. A elevada correlação observada entre a condutividade elétrica e Cu nas amostras das zonas de transição climática, sugere que essas variáveis estão associadas, e esse fato pode ser atribuído ao uso de cobre na cafeicultura que é a principal atividade agrícola desenvolvida nessa região.In this study, samples of honey produced in three different regional climates in the southwest Bahia, Brazil (semi-arid, Atlantic and Transitional Forest Zones) were characterized on the basis of their mineral and trace elements, ash content and electrical conductivity. The metals were determined by atomic absorption spectrophotometry. The cluster and principal component analysis (PCA) methods were applied to the chemical concentration data in order to study the chemistry variables capable of promoting a characterization of the honey produced in each area. Cluster analysis and PCA distinguishes the different groups of honey samples corresponding to each region of the three geographical origins. The high correlation between electrical conductivity and Cu observed in honey samples from transitional forest zones suggested a coupling to the nutrient cycle, and can be attributed to use of copper compounds in coffee production, a major activity developed in all transitional forest zones.

“…[1][2][3][4][5] Both elements are quite often determined in this matrix using air-acetylene flame atomic absorption spectrometry (FAAS), however, due to the complexity of the samples, i.e., the very high content of the monosaccharides, the easily ionized elements like K and Na, phosphates and the other anions, their measurements with the aid of FAAS may encounter some problems related to the matrix effects. 6 In reference to the possibility of the routine analyses and the quality and food safety control measurements of honey, the selection of a suitable procedure for the sample treatment is of a special importance in this case because it decides about the time of the analysis and the dependability of the results.…”

Um procedimento para preparo de amostras, baseado na extração em fase sólida e eluição em duas etapas foi desenvolvido para a determinação da concentração total de Ca e Mg em méis de abelha. As amostras de mel foram tratadas como segue: soluções de amostra (50 mL) a 5,0% (m/v) foram passados a uma vazão de 20 mL min -1 , através de resina Dowex 50W×8-400, para reter íons Ca(II) e Mg(II) e separá-los da matriz contendo glicose e frutose, e dos minerais aniônicos. Depois, 20 mL de uma solução de HNO 3 0,5 mol L -1 foram usados para remover os íons K e Na. Finalmente, Ca e Mg foram eluídos com 5 mL de solução de HCl 2,0 mol L -1 antes da medida de suas concentrações por espectrometria de absorção atômica em chama (FAAS). O procedimento proposto para o preparo da amostra foi rápido (30 min) e permitiu medir as concentrações de Ca e Mg em mel, com precisão de 1-5% e exatidão de 1-3%. Os limites de detecção de 24 ng g -1 de Ca e 4,4 ng g -1 de Mg foram obtidos para FAAS com este procedimento.A sample preparation procedure based on the solid phase extraction and the two-step elution was developed for the determination of the total concentrations of Ca and Mg in bee honeys. The honey samples were treated as follows: the 5.0% (m/v) sample solutions (50 mL) were passed at the flow rate of 20 mL min -1 through the resin beds of Dowex 50W×8-400 to retain the Ca(II) and Mg(II) ions and separate them from the matrix of glucose and fructose in addition to the anionic minerals. Afterwards, 20 mL of a 0.5 mol L -1 HNO 3 solution was used to remove the K and Na ions. Finally, Ca and Mg were eluted prior to the measurements of their concentrations by flame atomic absorption spectrometry (FAAS) using 5 mL of a 2.0 mol L -1 HCl solution. The proposed sample preparation procedure was fast (30 min) and enabled to measure the concentrations of Ca and Mg in honey with the precision of 1-5% and the accuracy of 1-3%. The limits of detection of 24 ng g -1 of Ca and 4.4 ng g -1 of Mg were obtained for FAAS with this procedure.

“…The content of these elements can provide essential information for consumers, which is why the estimation of quality parameters is so important. In recent years, concentration patterns of trace elements were widely used in food authenticity studies [1][2][3][4][5][6]. Because Poland produces many types of unifloral, multifloral and honeydew honey that are commercially available, we developed and applied analytical methods to measure the content of 13 major and trace elements in honey.…”

“…Among commercially available CRM, one hardly finds an equivalent of the complex honey matrix, in particular with regard to high carbohydrate content. Hence, in many research areas, other CRM like apple leaves (SRM 1515) [3,[8][9][10][11][12], brown bread (BCR 191) [7], or corn (NBS 8413) [4,5] are commonly applied. Due to the lack of matching CRM, other procedures are used, for instance various preparations of samples [3,8] or applying different experimental techniques [13,14].…”

A method for simultaneous ICP-MS determination of 13 elements in three types of honey from Poland is described. The method was validated, and the uncertainty budget was set up. The results obtained for the relative expanded uncertainties U rel (k = 2) were 15.1% for Al, 18.6% for B, 18.8% for Ba, 7.9% for Ca, 24.4% for Cd, 7.24% for Cu, 7.9% for K, 4.8% for Mg, 8.3% for Mn, 12.7% for Na, 14.9% for Ni, 12.5% for Pb and 13.4% for Zn. Traceability of the measurement results was established based on the use of the corn flour CRM INCT-CF-3 and the apple leaves CRM SRM 1515 and by analyzing spiked samples. Recovery rates between 94% (Zn) and 107% (Na) were found. The detection limits of all elements studied showed the suitability of the procedure for routine analyses. Summarizing it can be concluded that the described analytical procedures to measure the mass fractions of 13 elements in honey samples with established traceability and evaluated uncertainty allow to obtain reliable and internationally comparable results.
