“…Electrical conductivity has become an increasingly common analysis; its value is related to the quantity of minerals, organic acids and proteins. Additionally, the assessment of electrical conductivity is useful in certifying honey authenticity/adulteration, as it facilitates discriminating between blossom honey types and honeydew [3,20,51]. Highly similar results were obtained from investigations carried out on the same floral type of honey, with values also below 0.8 mS cm −1 (Table 4).…”

“…Honey pH and acidity are correlated with the internal amount of microorganisms, enzymatic activity and the presence of organic acids. A low pH indicates a good environment that inhibits microorganism growth, while the free acidity level is a biochemical marker for honey samples freshness [34,51]. Similar values of free acidity were found among Serbian acacia honey samples [47]; these were the lowest values when compared to other types of honey (Table 4).…”

“…Flanjak et al, found a strong statistically significant positive correlation between honey EC and TPC (r = +0.837) [29], while in another study, this correlation had a lower value (r = +0.55) [54]. In sunflower honey samples from Serbia, Živkov Baloš et al found a moderate correlation between electrical conductivity and ash mass fraction (r = +0.611) [51]. To compare similarities between studied parameters, we used a color circular hierarchical cluster analysis (HCA).…”

Phenolic and Total Flavonoid Contents and Physicochemical Traits of Romanian Monofloral Honeys

Since ancient times, honey has been appreciated not only for its sensorial traits, but also for the observed effects in rejuvenation and treatment against several bad health conditions, when used externally or internally, along with other beehive products, such as pollen, propolis and royal jelly. Today, it is known that such effects are generated by compounds bearing antimicrobial, anti-inflammatory, and antioxidative features (enzymes, polyphenolic molecules). The purpose of this study was to assess the total phenolic and flavonoid contents of 28 samples of Romanian raw monofloral honey (acacia; linden; rapeseed, sunflower and mint), and to establish their correlations with several qualitative parameters. Pearson’s test revealed a strong positive correlation between total phenolic content and total flavonoids (r = 0.76) and color intensity (r = 0.72). For total flavonoid content, correlations were strongly positive with color intensity (r = 0.81), ash content (r = 0.76) and electrical conductivity (r = 0.73). The relevant levels of polyphenols and flavonoids identified in the analyzed honey types demonstrate its antioxidant potential, with essential nutritional and sanogenic features in human nutrition.

“…The mass concentration of respirable particles in the air was determined according to the SOP MDL-055 (2003) standard procedure [36], which measures the mass of sampled particles on PM10 filters. The dissolution of deposits on the exposed filter was performed by the microwave digestion method under the standard CEN/TC 264 N 799 (2006) [37]. For this, Merck chemicals of high ultra-pure grade and double-distilled water (MilliQ, 18.2 MΩ) were used.…”

“…Živkov-Baloš (2021) pointed out that the composition of honey includes more than 20 organic acids (tartaric, citric, oxalic, acetic, etc. ), which amount to about 0.50% of the honey [37]. The presence of acids and the pH value of the honey depend on the types of plants from which the honey is produced and on the geographical location.…”

The Importance of Measuring Arsenic in Honey, Water, and PM10 for Food Safety as an Environmental Study: Experience from the Mining and Metallurgical Districts of Bor, Serbia

Arsenic and toxic metals can reach food and honey through water and air, thus endangering the safe consumption of the same. These toxic substances can damage human health through the food chain, which is contrary to the goals of sustainability related to health and food safety. It is necessary to continuously control and measure the concentration of pollutants to ensure the safety of food produced near mining areas. The arsenic content of honey samples from a territory up to 32 km in diameter from the mine (Bor town, east Serbia, and its surroundings), as determined by ICP-MS, is presented in this paper. PM10 particles and water were also analyzed for arsenic content. Pearson’s correlation and hierarchical cluster analysis were used for statistical analysis. The obtained results showed that the content of arsenic in honey was below the maximum allowable concentration (MAC) value. The honey was not contaminated, although the results showed that the concentrations of arsenic in water and PM10 particles were elevated. The results indicate that the environment in these areas is damaged and point towards caution.

Quality Profile of Several Monofloral Romanian Honeys

The objective of this research was to evaluate some quality-defining physicochemical parameters (moisture, specific gravity, pH, free acidity, ash, electrical conductivity, total phenols, and total flavonoids content, K, Ca, Mg, Na, and P) of seven Romanian monofloral honeys (linden, acacia, rapeseed, sunflower, mint, raspberry, and chestnut) collected in 2017. The investigated quality parameters are mainly within the recommended limits set by standards for honey. Sample analyses indicate the presence of antioxidants, such as TPC (17.9–73.2 mg GAE/100 g) and TFC (0.84–4.81 mg QE/100 g), and high amounts of K (101–1462 mg kg−1), Ca (58.3–167.5 mg kg−1), Mg (24.8–330.6 mg kg−1), Na (94.5–233.3 mg kg−1), and P (34.1–137.2 mg kg−1). The Pearson’s correlations between some parameters (such as color/TFC, color/Mg, color/P, EC/Ash, mm Pfund/TFC, TPC/TFC, K/Ash, P/Mg), together with PCA, HCA, and ANOVA statistics, highlight three main factors that explain the variability in the dataset and could be attributed to stability, mineral, and color/antioxidant contributions. FTIR spectra confirm the authenticity of all the monofloral honeys. The results and data processing confirm the influence of environmental elements (soil, water, air) on the honey composition and highlight the quality of honey, as a complete food and a therapeutic product.
