Concentration of Minerals in Nectar Honeys from Direct Sale and Retail in Poland

Abstract

The aim of the study was to compare the content of selected minerals in different nectar honeys (acacia, buckwheat, raspberry, linden, rapeseed, and multifloral) available on the Polish market. The degree to which the demand for eight minerals (K, Na, Mg, Ca, Zn, Fe, Mn, Cu) by adults is met by a portion of 100 g of honey was estimated as well. The material consisted of 34 artisanal honeys from direct sale and 34 samples purchased from retail stores. The artisanal honeys contained significantly more K, Mg, and Mn, but significantly less Na and Fe than the honeys purchased from the retail stores. The raspberry honey contained significantly the most K and Ca (1104.7 and 68.8 mg kg−1), the multifloral honey contained the most Ca and Mg (68.5 and 48.0 mg kg−1), and the buckwheat honey contained the most Zn and Mn (3.97 and 4.96 mg kg−1). The highest content of Na was shown in buckwheat and linden honeys (79.1 and 80.0 mg kg−1). Consumption of 100 g of honey from direct sale satisfied from 2.5 to 4.5% of the recommended intakes for K and from 10.4 to 17.3% for Mn, while the same portion of honey from retail satisfied from 1.6 to 4.8% for Fe, and from 2.3 to 6.1% for Zn and Cu. The buckwheat honey met to the greatest degree the recommended dietary intakes for Mn (16.5–27.6%), followed by raspberry honey (10.0–16.7%) and multifloral honey (6.9–11.6%).

Relationships between the Content of Phenolic Compounds and the Antioxidant Activity of Polish Honey Varieties as a Tool for Botanical Discrimination

“…Multivariate analysis (e.g., principal component analysis-PCA; hierarchical cluster analysis-HCA; linear discriminate analysis-LDA, and others) has very often been used to evaluate and/or classify honeys in terms of their chemical composition or their physicochemical or biological properties. Numerous papers have confirmed the suitability of this method for honey, used either alone [ 10 , 11 , 12 , 13 , 14 ] or in combination with spectroscopic techniques [ 15 ].…”

Unexpected Value of Honey Color for Prediction of a Non-Enzymatic H2O2 Production and Honey Antibacterial Activity: A Perspective

“…The first observation that darker honeys had a higher mineral content than light honeys was made by Anklam in 1998 [79]. Subsequent correlative studies revealed significantly higher quantities of transition metal ions Fe, Zn, Cu, and Mn in buckwheat, heather, and honeydew in comparison to light honeys such as acacia or rape honey [74,[80][81][82].…”

“…The concentrations displayed in our study are much higher than that found in other local and foreign honeys. 44 The critical aspect of this analysis is based on both the composition of the soil and the floral diversity.…”
