Content of mineral elements in honey and its biological value in conditions of feeding to bees of citrates of Сo, Ni, Ag and Сu

Abstract

The purpose. To determine influence of citrates of Co, Ni, Ag and Cu on the content of separate mineral elements in honey and to assess its quality. Methods. In samples of honey they determined content of Cu, Fe, Co, Cr, Zn, Pb, Cd using atomic-absorption spectrophotometer of SF-115 PK, and physicochemical parameters of honey using conventional procedures. Results. Application of citrates of microelements with sugar syrup for supplementary feeding of honeybees testified to correcting impact of citrates on the content of separate beneficial and toxic elements in honey and its biological value during ripening. At the same time there were changes of quality content of honey of the probed groups. Conclusions. Positive changes in samples of both probed groups were gained in the content of Fe, Cu, Cr, Pb and Cd in honey, as well as its physicochemical parameters and quality with heightening the content of proline, diastase number and pH content. It confirmed expediency of use of addition of citrates of Co, Ni, Ag and Cu for the purpose of correction of processes of mineral nutrition of honeybees and quality of their produce that is more expressed at addition of Ag and Cu to sugar syrup.
