“…In addition, the trace minerals of Fe, Zn, Cu, and Pd were detected in all honey samples at low concentrations (Table 3). All values found in the samples were within the ranges reported for honeys from other study (Aazza et al., 2013; Fernández‐Torres et al., 2005; Imtara et al., 2018). The mineral composition of honey samples is also a potential indicator of its geographical origin, as well as a biomarker of possible pollution by toxic metals (Alves, Ramos, Gonçalves, Bernardo, & Mendes, 2013; Pohl, 2009).…”

“…Regarding the bioactive compounds, namely polyphenolic, flavones and flavanol, a great variability was seen among the analyzed samples, suggestion the intervention of the reported floral influence (Fernández‐Torres et al., 2005), as they originate from different botanical sources. The lowest polyphenolic content value was obtained in hairy fleabane (S2) from Salfeet (26.96 ± 0.71 mg/100 g), while the highest value was obtained in thyme honey (S1) from Al‐Khalil (70.73 ± 0.71 mg/100 g).…”

Physicochemical characteristics, main minerals, and antioxidant activity were determined for Palestinian honey samples belonging to different floral and geographical origins. The features of the analyzed samples were within the established international standards for honey quality control. One clear exception was the hydroxymethylfurfural (HMF) of the Ziziphus sample purchased from the Jericho region, which is the lowest city in the word characterized by a hot desert climate. The observed HMF value was 81.86 ± 2.64 mg/kg being two folds the maximum allowed in honey samples (40 mg/kg). As a second objective of the present work, the parameters were divided into two groups with different discriminatory power. The assessed physicochemical parameters, and the antioxidant activities, specific to the botanical origin discrimination, were used to run the first PCA. A strong correlation could be seen between the bioactive compounds and the antioxidant activities despite the geographical origin of the samples. Thyme and Ziziphus samples were the best samples, while citrus sample presented the lowest activity. Regarding the geographical discrimination, Ash and mineral contents in addition to the electrical conductivity were used. The output PCA conserved high represent ability of the data in the two‐first components being 82.72% and 9.60%. A little discrimination between the samples produced in the north and those produced in the south of the country, but it was not perfect. The intervention of the botanical variability could be the reason.

“…The minerals make their way into the nectar and are subsequently incorporated into the honey produced by bees (STANKOVSKA; STAFILOV; SANJ, 2008). Accordingly, the composition and the content of metals in honey, particularly major and minor metals, is affected by the composition determined by geochemical and geological features (FERNÁNDEZ-TORRES et al, 2005). Since soil and plants are natural sources that have a great influence on the mineral composition of honey, information on the metal profile is suitable for categorizing honeys according to their floral and geographical provenance (POHL, 2009).…”

“…The most abundant metal in honey is K (FERNÁNDEZ-TORRES et al, 2005). Other major metals present in honey are Na (second most common), Ca, and Mg. Cu, Fe, Zn, and Mn are present in intermediate quantities (POHL, 2009).…”

“…Almeida-Anacleto and Marchini (2004) found Mg as the third most abundant mineral in their honey samples. Fernández-Torres et al (2005) determined the levels of eleven elements (Zn, P, B, Mn, Mg, Cu, Ca, Ba, Sr, and K) in 40 honey samples from four different plant sources from different locations in Spain. These authors found that K, Ca, and P showed the highest concentrations: 434.10-1935.00 mg/kg for K, 42.59-341.00 mg/kg for Ca, and 51.17-154.30 mg/kg for P. The levels of Cu (0.53-2.12 mg/kg), Ba (0.11-1.26 mg/kg), and Sr (0.26-1.46 mg/ kg) were the lowest in all honey samples.…”

ResumoEste trabalho avaliou propriedades físico-químicas, teores de proteína e minerais em méis do Ceará, um dos principais exportadores do País. Também foi analisada a importância nutricional com relação aos minerais detectados. As propriedades físico-químicas foram determinadas pelos métodos da AOAC e CAC, o conteúdo de proteína pelo método de Bradford e os minerais por espectrometria de absorção atômica. Todas as análises foram feitas em triplicata. Os níveis dos macrominerais sódio (Na), potássio (K), cálcio (Ca), e magnésio (Mg) variaram de 1,80-47,20, 21,30-1513,30, 14,58-304,82 e 2,48-28,33 mg/kg, respectivamente, e os elementos traços ferro (Fe), cobre (Cu), manganês (Mn), zinco (Zn), selênio (Se), e cromo (Cr) variaram de 0,12-8,76, 0,07-1,29, 0,06-1,96, 0,07-1,85 mg/kg, 0,36 × 10 -3 -62,00 × 10 -3 e 22,50 × 10 -3 -170,33 × 10 -3 µg/kg, respectivamente. A amostra de Myracrodruon urundeuva apresentou altos teores dos principais minerais (Na, K, Ca, e Mg). O teor de proteínas para o mel de Anacardium occidentale foi o maior (1121,00 µg/g) entre as amostras de méis analisadas. Entre os minerais, detectados, K apresentou a maior concentração seguido por Ca, Na, e Mg. A pesquisa de elementos traços pode indicar contaminação ambiental. As amostras de méis estudadas apresentaram-se livres de contaminação por elementos traço, excetuando-se quanto ao Mn, em que apenas a amostra proveniente de Piptadenia moniliformis apresentou-se dentro da legislação. As variações dos constituintes químicos devem-se provavelmente às variadas origens florais e os teores de proteínas e minerais ratificam a importância nutricional dos méis do Ceará. Palavras-chave: mel de Apis mellifera; origem floral; importância nutricional. AbstractThis study evaluated the physicochemical properties and protein and mineral content of honey samples from Ceará State, Northeastern Brazil, one of the major honey exporters in the country. Nutritional importance of the minerals detected was also analyzed. Physicochemical properties were examined according to the AOAC and CAC official methods; the protein content was determined using the Bradford method, and the minerals were analyzed by atomic absorption spectrometry. All analyses were performed in triplicate. The levels of macrominerals sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg) varied from 1. 80-47.20, 21.30-1513.30, 14.58-304.82, and 2.48-28.33 mg/kg, respectively, and the trace elements iron (Fe), copper (Cu), manganese (Mn), zinc (Zn), selenium (Se), and chromium (Cr) varied from 0.12-8.76, 0.07-1.29, 0.06-1.96, 0.07-1.85 mg/kg, 0
