Abstract: The problems of production of high-quality and safe food products and food raw materials are now quite relevant and widely discussed all over the world. In conditions of not decreasing intensity of technogenic pollution of the environment, the production of high-quality environmentally friendly beekeeping products becomes more and more problematic. The purpose of this work was to study the physicochemical parameters, the content of micro-, macroelements and the presence of heavy metals in acacia honey. The object for the study was samples of acacia honey, selected in the countryside and from the Chisinau municipality. The content of micro- and macroelements and the presence of toxic elements in acacia honey were determined by the atomic absorption spectrometry method at the Institute of Chemistry of the ASM. It is revealed that the mass fraction of water in acacia honey has made 16.17%, a mass fraction of invert sugar – 90.05%, sucrose – 3.85%, Diastase number – 13.17
gothеunits, oxymethylfurfural – 6.39 mg/kg, the general acidity – 1.19 cm3 NaOH solution in (miliequivalent) on 100 g of honey and ash-content – 0.09%. It is revealed that in akatsiyevy honey minerals average Mn – 0.287 mg/kg, Zn – 0.448 mg/kg, Cu – 0.318 mg/kg, Fe – 2.585 mg/kg, Cr – < 0.12, Ni – < 0.12, and macroelements: calcium – 34.18 mg/kg, magnesium – 13.36 mg/kg, potassium – 363.28 mg/kg, sodium – 19.37 mg/kg, 63.45 mg/kg, phosphates – 63,45 mg/kg. It is established that acacia honey on average contains heavy metals: lead – < 0.10 mg/kg, cadmium – < 0.01 mg/kg, strontium – < 2.3 Bq/kg, zinc – 0.448 mg/kg, copper – 0.318 mg/kg. The mineral structure of honey can depend on the region of origin of melliferous cultures, including on soil and climatic conditions.
