According to standard methods, we studied the species composition of pollen grains, physicochemical parameters of centrifugal, honeycomb, and «zabrus» sunflower honey.(zabrus honey was obtained from wax caps, which we cut with an apiary knife from honeycombs filled with nectar and sealed by bees). The content of lead (Pb) in honey from sunflower obtained in the conditions of Polissya is 1.8–2.1 times higher than the State sanitary norms. The largest amount of it is in the centrifugal honey. In acceptable amounts, the heavy metals cadmium (Cd), arsenic (As), and 137Cs were present in honey. Pesticides, dichlorodiphenyltrichloromethylmethane, and hexachlorane were not detected in the samples. We investigated the bactericidal action against bacterial growth of typical cultures of Proteus vulgaris, Escherichia coli, Klebsiella pneumonia, Salmonella Typhimurium, and Staphylococcus aureus. Zubrus sunflower honey showed the highest antimicrobial and antioxidant properties. We found that the value of antioxidant activity (AOA) of sunflower honey depends on the method of its production, duration of storage, and solutions of extracts (alcohol, aqueous) used in research. Laboratory control of transgenic organisms in flowers and sunflower pollen did not reveal the target sequences of the cauliflower mosaic virus (CaMV) 35S promoter and the NOS terminator (nopaline synthase) of the plasmid Agrobacterium tumefaciens
За стандартними методиками дослідили видовий склад пилкових зерен, фізико-хімічні показники центрифужного, стільникового та забрусового соняшникових медів (забрусовий мед отримали із воскових кришок, які зрізали пасічним ножем у стільників, що були заповнені нектаром і запечатані бджолами). Вміст свинцю (Pb) в медах із соняшника отриманого в умовах Полісся в 1.8 – 2.1 рази перевищує Державні санітарні норми. |
