Significant parameters of Bulgarian honeydew honey

Abstract

Three main physico-chemical parameters (moisture content, pH, and electrical conductivity), 19 elements contents (K, Ca, Mg, P, S, Al, As, Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, Pb, Sr, V, and Zn) and microscopic characteristics of 30 honeydew honey samples from Bulgaria were evaluated. The most abundant elements were K, P, Ca and Mg in the honeydew honey investigated and low concentrations of toxic elements and heavy metals were established. The electrical conductivity -one of the most important parameters for honeydew honey, exceeded 0.8 mS*cmˉ¹. The honeydew index in Bulgarian honeydew honey varied widely and its values were often below 3.

Physicochemical Properties and Pollen Profile of Oak Honeydew and Evergreen Oak Honeydew Honeys from Spain: A Comparative Study

“…All the honey samples exhibited an electrical conductivity higher than 0.800 mS/cm. These values are consistent with those published by other authors for honeydew honey obtained from different areas of origins [1,4,20,41,42]. It is also noteworthy the nectariferous secretions of Erica plants may contribute to higher phenolic content and higher sugar content (especially, glucose) in oak honeydew honeys since according to some authors, honey obtained from northwest Spain exhibits these qualities [6,24].…”

Physicochemical analysis and phenolic profile of polyfloral and honeydew honey from Montenegro

“…The obtained values for honeydew honey samples varied between 0.94-1.13 mS cm À1 ( Table 1). These results are similar with reported values for some honeydew honey samples from other geographical origins such as Romania, 16 Serbia, 18 Bulgaria, 19 Croatia, 20 Brazil, 21 or with r honeydew honey from Greece. 22 Range of electrical conductivity for polyoral honey goes from 0.27 to 0.78 mS cm À1 , very closely to the range 0.40-0.75 reported by Nascimento et al 23 The mean value for poly-oral honey is 0.59 mS cm À1 , similar to the results of Popek et al 14 Results of free acidity is in compliance with recommended value of not more than 50 meq.…”

Coniferous Honeydew Honey: Antibacterial Activity and Anti-Migration Properties against Breast Cancer Cell Line (MCF-7)

“…In the case of rapeseed honey, the conductivity was 0.144 mS/cm, typical for nectar honeys (below 0.8 mS/cm). The values of the tested parameters obtained for honeydew honey were mostly within the ranges previously determined for a larger pool of samples from the same region [5], as well as other honeydew honey samples tested by other teams [8,39,40]. Water activity is an additional parameter not included in legal regulations, but it reflects well the microbiological stability of the product.…”
