“…The elements with a concentration < LOQ in all samples were Co and Hg. All results were in the range of the published data [ 3 , 7 , 10 , 11 , 13 , 16 , 18 , 22 , 39 ]. Significant differences in Ca, Ti, Mn, Cr, V, Sb, As and Cd content among honey botanical types were found ( p < 0.05).…”

The concentrations of 19 chemical elements have been determined in 36 honey samples of different botanical (wildflower, eucalyptus, eucalyptus red flowers, prickly pears, lemon blossom, thyme, almond, rosemary and jujube) honeys from the three geographical areas of Tunisia (Sidi Bouzid, Nabeul and Sfax) using inductively coupled plasma mass spectrometry (ICP-MS). The aim of this work was to use the multielement analysis together with chemometric tools to verify the botanical and the geographical origin of honeys. The correlation on the basis of mineral element content between the honey samples and their botanical and/or geographical origins was in some measure achieved. The data collected on the samples were also used to evaluate the nutritional quality and the potential health risks associated with elements via consumption of the Tunisian honey. According to the results obtained, the intake of essential elements was small, and the potential health risks associated with toxic or potentially toxic elements via consumption of this food were overall insignificant.

“…Thus, the supply and quality of pollen, which directly influences the amount of N, could be related to the geographical allocation of the source of the honey. Furthermore, Fechner et al, 10 using ICP-MS data from the same samples used here, obtained a classification method for geographical origin reaching 76% of prediction accuracy.…”

“…In order to simplify the determination of the origin of the honey, methods based on the elemental analysis of the composition of honey have been proposed. [7][8][9][10][11][12][13][14][15] These methods use analytical techniques, such as atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS), combined with multivariate data analysis. The disadvantages of the aforementioned techniques are the high cost per analysis, since they require gases and high-purity reagents, in addition to the time required for the sample pretreatment.…”

Honey is a natural food that is valued worldwide for its nutritional and therapeutic values. Therefore, authentication of honey based on geographical origin is a guarantee of its genuine properties of honey. In this article, an evaluation of spark discharge-assisted laser-induced breakdown spectroscopy (SD-LIBS) for certification of the geographical origin of honey is reported. Forty-nine samples of multifloral honey produced in four Argentine provinces were considered. The results showed that best classification performance was obtained using smoothing, generalized least squares weighting (GLSW) and mean centering for spectral preprocessing, added to the k-nearest neighbor (k-NN) or Support Vector Machine (SVM) classification algorithms, which provided 100% of correct classification. More importantly, the results of Partial Least Squares -Discriminant Analysis (PLS-DA) pointed to N, Ca, K, Cu, Fe and Mn as key elements for the certification of geographical origin. In addition, the best indicator for verification of the source of honey was found to be in the assessment of the amount of N in honey. These findings confirm SD-LIBS as a promising tool for authentication of honey origin and quality, providing a simple, fast and environmentally friendly solution. The method can be useful for industry, the marketplace and other areas related to food authentication.

“…Different methods are used for analysing the composition of honey and identifying its authenticity, including physicochemical parameters assay [51], using linear discriminant analysis (LDA) [227] or carbon isotope ratios and trace elements [228] and pollen analysis (melissopalynological analysis) [100,229]. Other modern assets available for honey authentication are the chemometric procedure [224,230], mass spectrometry [231,232], high-performance liquid chromatography (HPLC) [233,234], spectroscopy (UV visible), near-infrared (NIR) [114,225], gas chromatography coupled with mass spectrometry (GC-MS) [235,236] or nuclear magnetic resonance (NMR) [237,238].…”

The nutritional and therapeutic aspects of natural products have gained more interest in recent years, owing to the importance that has been given to health and well-being. In this regard, honey represents an organic product whose high level of biologically active compounds and valuable nutrients have been extensively studied in order to prove its ability to provide an enhancement in health status. The use of honey in the process of healing or preventing certain diseases has been practiced throughout history and is now known as apitherapy. The aim of this review is to expand the knowledge and understanding towards the physicochemical characteristics of honey and the action of its main bioactive compounds towards health-beneficial properties (antioxidant, antimicrobial, antifungal, antiviral, etc.) for apitherapeutic purposes. Notwithstanding all the assets, the usage of honey for medical purposes encounters some limi-tations regarding the factors that may affect the therapeutic potential of honey in apitherapy that will be pointed out in this overview.
