“…Isotopic analysis is currently combined with different types of analysis, such as analysis of mineral elements with inductively coupled plasma optical emission spectroscopy, near‐infrared spectroscopy, or NMR profiling, for fast and sharper fraud detection. As yet, no studies have investigated combining these techniques with determination of major and minor sugars using ion chromatography (IC) with pulse amperometric detection (PAD) and charged aerosol detection (CAD) to increase the possibility of detecting fraud.…”

"Aceto Balsamico di Modena" (ABM) is a protected geographical indication salad dressing obtained from cooked and/or concentrated grape must, with the addition of wine vinegar and a maximum of 2% caramel (EU Reg 583/2009). In this study, we investigated whether the combination of C/ C of ethanol using isotope ratio mass spectrometry with H-site-specific natural isotope fractionation-nuclear magnetic resonance and minor sugars using ion chromatography with pulse amperometric and charged aerosol detection is able to improve detection of sugar addition to ABM must. A large selection of authentic Italian grape musts and different samples of balsamic vinegar with an increasing percentage of added beet, cane, and sugar syrups were considered. The possible degradation of sugars in the ABM matrix during shelf life was also investigated. While stable isotope ratios analysis remains the favoured method for determining cane and beet sugar addition, dosage of minor sugar (in particular maltose) proved to be very useful for detecting the addition of sugar syrup. Thanks to this innovative approach, 3 out of 27 commercial ABMs were identified as adulterated. A combination of stable isotope ratio and ion chromatography with pulse amperometric and charged aerosol detection analysis can be therefore proposed as a suitable tool for detecting the authenticity of ABM must.

“…The absence of clusters among the Melipona interrupta samples (Figure 2) may indicate that the individual Melipona interrupta sample types were highly heterogeneous, which suggests that floral nectar composition was highly variable and that there was a relationship between the "J" samples and Article the composition of the Apis mellifera samples. The trace-elements in a soil affect honey composition and the macro elements are influenced by the floral origins of the nectar [18]. The high similarity between some "J" and "M" samples may indicate that the soil in the area and the floral nectar collected by the different bee species were similar (Figure 2).…”

Graphical AbstractPossible sources of macro and micronutients, as well as potentially toxic elements in honey The aim of this study was to quantify the macro and trace element concentrations in Apis mellifera and Melipona interrupta honey samples from the Lower Amazonian region in order to evaluate if the samples of different geographical origin and/or species could be distinguished by their mineral content. In addition, it was evaluated the presence of potentially toxic metals in honey samples. The metal contents were determined by inductively coupled plasma optical emission spectrometry (ICP OES) and the most abundant metals found in the samples were K, Ca, Mg, and Na. The total metal (K, Ca, Mg, Na, Cd, Co, Ni, Fe, Mn, Cr, Al and Ba) concentration ranged from 127.7 ± 1.4 to 1844.4 ± 45.2 µg g -1 and from 102.7 ± 2.0 to 639.0 ± 15.3 µg g -1 in Apis mellifera and Melipona interrupta honey, respectively. All mineral content levels found in the honey samples were lower than the maximum established by Brazilian and international law (Cd and Cr 0.1 μg g -1 , Pb 0.30 μg g -1 , Ni 5 μg g -1 , Cu 10 μg g -1 , Zn 50 μg g -1 ). Furthermore, Cu, Pb, and Zn were not detected in any of the samples. However, potentially toxic elements, such as Cd, Co, and Ni, were detected in most of the commercial samples and in Apis mellifera honey from beehives that were close to livestock fields and/or soybean areas. Hierarchical cluster analysis (HCA) was used to study the mineral contents and it was possible to distinguish eight different groups of honey. However, the Melipona interrupta honey could not be separated into different groups.

Background: The official standard for quality control of honey is currently based on physicochemical properties. However, this method is time-consuming, cost intensive, and do not lead to information on the originality of honey. This study aims to classify raw stingless bee honeys by bee species origins as a potential classifier using NMR-LCMS-based metabolomics approach. Methods: Raw stingless bee honeys were analysed and classified by bee species origins using proton nuclear magnetic resonance (1H NMR) spectroscopy and an ultra-high performance liquid chromatography-quadrupole time of flight mass spectrometry (UHPLC-QTOF MS) in combination with chemometrics tools. Results: The honey samples were able to be classified into three different groups based on the bee species origins of Heterotrigona itama, Geniotrigona thoracica, and Tetrigona apicalis. D-Fructofuranose (H. itama honey), β-D-Glucose, D-Xylose, α-D-Glucose (G. thoracica honey), and L-Lactic acid, Acetic acid, L-Alanine (T. apicalis honey) identified via 1H NMR data and the diagnostic ions of UHPLC-QTOF MS were characterized as the discriminant metabolites or putative chemical markers. Conclusion: It could be suggested that the quality of honey in terms of originality and purity can be rapidly determined using classification technique by bee species origins via 1H NMR- and UHPLC-QTOF MS-based metabolomics approach.
