“…Total polyphenol content was reported to be high in other studies of honeydew honey samples 7 , 34 , 35 . In the present study, the total polyphenol content did not differ substantially between the tested honeydew honey samples (with the exception of sample #15), with an average value of 50 mg GAE/100 g of honey.…”

“…Honeydew honey possesses strong biological properties including antibacterial 1 , 3 , 4 , antibiofilm 5 , anti-inflammatory 6 , antioxidant 7 , as well as wound healing activity 8 . The antibacterial and antibiofilm activity of honeydew honey is comparable to manuka honey, which is currently used as medical-grade honey in clinical applications.…”

Honeydew honey is increasingly valued due to its pronounced antibacterial potential; however, the underlying mechanism and compounds responsible for the strong antibacterial activity of honeydew honey are still unknown. The aim of this study was to investigate the inhibition of bacterial growth of 23 honeydew honey samples. Activity of bee-derived glucose oxidase (GOX) enzyme, the content of defensin-1 (Def-1) and hydrogen peroxide (H2O2), and total polyphenol content were determined in the 23 honey samples. Our results demonstrated that antibacterial activity of honeydew honey was equivalent to medical-grade manuka and kanuka honey and was abolished by catalase. Although H2O2 is an important factor in the inhibition of bacterial growth, polyphenolic compounds and their interaction with H2O2 are the key factors responsible for high antibacterial activity of honeydew honey. In addition, our results indicated that the antibacterial activity of honeydew honey is not dependent on GOX-mediated production of H2O2 or the presence of Def-1.

“…This was not unexpected. Honeydew honeys have been reported to possess higher total phenol and flavonoid content, and higher antioxidant power than many nectar honeys (Escriche et al, 2014; Escuredo et al, 2013; Rodríguez Flores et al, 2015; Tuberoso et al, 2011). The TPC and TF reducing components of the two honeydews, however, were substantially comparable with those in the ferula and dill monofloral honeys (Table 1).…”

Thirty samples from thirteen Sicilian monofloral honeys by the local black honeybee, and two honeydew honeys, were studied to assess phenol content, reducing power and antioxidant capacity as well as correlations among these parameters. Honeys from Apiaceae showed the highest phenol amount and capacity to reduce ferric ion and stable chemical radicals, whereas honeys from Leguminosae the lowest. All honeys were active against myoglobin-derived radicals usually formed in red meat after storage and/or heating and significant correlation (p = 0.023) was found between flavonoid content and deactivation rate of this radical. Dill > almond > tangerine > thistle > sulla honeys inhibited formation of lipoperoxides in either iron/ascorbate or azoinitiator -induced membrane lipid oxidation, whereas eucalyptus honey was mostly effective in the metal-dependent model. Honeys by black honeybee possess remarkable reducing power and antioxidant potential against radicals of interest in dietary foodstuffs.

“…Spanish honeys studied by Escuredo et al [57] contained, on average, 112.8 mg GAE/100 g, with the lowest value of 78.4 mg GAE/100 g for eucalyptus honey and the highest of 181 mg GAE/100 g for heather honey. Honeydew honeys studied by Flores, Escuredo and Seijo [31] contained, on average, 100 to 154.4 mg GAE/100 g polyphenols, depending on the production year. Gašić et al [40] determined the TPC ranging from 6 to 136 mg GAE/kg for Serbian polyfloral honeys.…”

“…The results of melissopalynological analyses are shown as the percentage of each pollen type content. According to Flores et al [31], pollens are classified as dominant (concentration equal to or upper than 45%), accompanying (concentration between 15% and 45%), or important (concentration between 3% and 15%). Moar [32] indicated that the content of 45% is a universal and minimal limit for the classification of honey as monofloral.…”

Antioxidant Activity and Phenolic Profile of Selected Organic and Conventional Honeys from Poland

Honey is a natural food product hypothesized to have significant health-beneficial value. The results of recent studies indicate that the biological activity of honey can also be ascribed to phenolic compounds and their antioxidant activity. The aims of this study were: To determine the phenolic profiles of several varieties of Polish honey and their correlation with various factors influencing the quality of honey, plus to verify the impact of production method (organic/conventional) and the pollen content on these profiles. In total, 11 organic and 11 conventional honey samples from Poland were investigated. The botanical origin of the samples was identified through melissopalynological analysis, whereas individual phenolic compounds were determined by the LC/MS analysis. The Folin–Ciocalteau assay was used for the determination of the total phenolic content (TPC). Moreover, the CIE L*a*b* color values were measured and matched with the above-mentioned parameters. The results of the study contribute to the discussion on the health benefits of organic farming. It was found that chrysin may act as a potential indicator compound. The study confirms the existence of the link between TPC and color, and it shows that there is a correlation between pinocembrin and galangin, two compounds that are reported to ameliorate insulin resistance.
