The research was conducted on four groups of bees families-analogs, three families in each group. Bees of the control (I) group were fed with 50% of sugar syrup (s.s) in the amount of 300 ml / family / week. Bees of the II (experimental) group with 300 ml of s.s. received 30 mcg of Co in the form of citrate, ΙΙΙ - with 300 ml of s.s. - 60 mcg of Ge in the form of citrate, group IV - with 300 ml of s.s. of 30 mcg of Co and 60 mcg of Ge in the form of citrate. Duration of coagulation of syrup and citrates Co and Ge was 4 weeks. Samples of perga and honey were investigated, in which the content of individual heavy metals (Cu, Fe, Co, Ni, Pb, Cd) was determined on an atomic absorption spectrophotometer SF-115 PC, as well as the qualitative indicators of honey. Statistical analysis of the results was performed with the determination of the mean values and probability according the Student's coefficient.Researches have shown changes in the correlation of trace elements in its products with an increase in the content of Fe in honey when fed 30 mcg Co and a decrease in the concentration of toxic heavy metals such as Pb and Cd in perga at 60 mcg Ge (III g), 30 mcg Co and their combination in the fourth group. More expressed physiological effect of applied nanotechnological Co and Ge citrates on the content of the research microelements in perga and honey was established under the conditions of complex feeding of 30 mcg Co and 60 mcg Ge citrates. Feeding of bees with Co and Ge citrates caused an increase parameters of honey, as evidenced by the probable increase in diastasis number and proline content in honey of bees of the experimental groups. Organoleptic characteristics of honey when feeding bees with Co and Ge citrates did not change significantly in the experimental groups compared with the control and met the current standards of DSTU 4497: 2005. It is concluded that feeding bees with the addition to sugar syrup Co and Ge nanotechnological citrates stimulates mineral exchange in their organism and optimizes the content of trace elements and quality indicators in products.
