                  An essential condition for ensuring the intensive development of bee families and
            increasing their strength is the provision of insects with a sufficient amount of high-quality
            fodders. In the winter-spring period, bee families often lack their own forage supplies, a large
            number of cells completely crystallized, especially on the honey flow of cruciferous and oil
            plants. Inadequate amount of feed-in bikes requires the use of feeding bees with high quality
            and biologically complete feed.
                  Antioxidant properties were determined to  study the biological value of sugar-honey
            dough and honey syrup prepared on the basis of the centrifuge and capped sunflower honey.
                  The composition of sugar-honey dough was as follows: 81 % – sugar powder; 16 % –
            honey; 3 % – water. 80 % honey and 20 % of  water were used to prepare honey syrup.
            Sunflower honey for research was obtained in the conditions of the Zhytomyr region of
            Ukraine.
                  The determination of the total antioxidant activity of the products was carried out using
            a photometric method with a high sensitivity to antiradicals at the laboratory of the Institute
            of Biodiversity Conservation and Biosafety at the Slovak University of Agriculture in Nitra.
            The results were processed and analyzed using Microsoft Office Excel 2010.
                  The obtained results of the research have shown that higher antioxidant properties are
            characteristic for feeding products made on the basis of capped honey. It was noted that the
            higher potential of the antioxidant activity of sugar-honey dough and honey syrup made of
            both centrifuges and capped honey was in water solutions. It was found that the antioxidant
            activity of sugar-honey dough was higher in the product made of capped sunflower honey. At
            the same time, its potential in water solution was 5.62 units, that by 2.45 units higher than in
            methanol solution. The use of capped honey for making a honey syrup has allowed obtaining
            the highest overall antioxidant activity of this fodder. The potential of the antioxidant activity
            of honey syrup with capped honey in a water solution was 9.54 units, which is by 2.93 units
            higher, compared with methanol solution.
                  Consequently, sugar-honey dough and honey syrup made of the centrifuge and capped
            sunflower honey show their antioxidant properties in both water and methanol solutions.
            However, we have noted that fodder products made of capped honey have a bigger biological
            value than of centrifuge honey. We can assume that this is due to a better biological activity of
            capped honey, compared with centrifugal one. Because capped honey contains a large number
            of organic acids, mineral compounds, vitamins, etc.

            Keywords: antioxidant activity, sugar-honey dough, honey syrup, bee families.
