Summary: Actuality. Sunflower honey is one of the most popular honeys in the world and in Ukraine. On the world market, sunflower honey makes up the largest percentage of Ukraine`s export supplies. As a rule, beekeepers receive it in an amount that is 2‒3 times higher than the honey harvest of other varieties. Constantly high commodity demand for honey is one of the reasons for its falsification. Since there is no approved method for detecting monofloral honey in Ukraine, solving this problem is important and relevant at the moment. Study purpose. The purpose of the study is to evaluate the quality of monofloral sunflower honey based on the determination of its organoleptic, physicochemical indicators and the content of pollen grains. Material and methods. Sampling of honey, analysis of organoleptic and physicochemical parameters was carried out in accordance with DSTU 4497: 2005 “Natural honey. Technical conditions”. Melisopalynological analysis and the ratio of fructose to glucose were carried out according to generally accepted international methods. Research results. 165 samples of sunflower honey from different regions of Ukraine were analyzed. Evaluation criteria for monofloral sunflower honey in Ukraine have been established. The degree of monoflorality of sunflower honey can range from 45.0% to 89.0%, with an average of 64.5%. Secondary pollens are mainly pollen from the legume family (peanut (Vicia spp.), clover (Trifolium spp.), pollen grains from the Cruciferae family, common goldenrod (Solidago virgaurea L.). According to organoleptic indicators, sunflower honey has a faint aroma of sunflower flowers, has a color from light yellow to dark yellow shades, consistency depending on the season (liquid, viscous, very viscous, dense). According to physical and chemical indicators: moisture ‒ 18.5%, proline ‒ 233.38 ± 53.76 mg/kg, electrical conductivity ‒ 0.35 ± 0.04 mS/cm, fructose to glucose ratio ‒ 1.12 ± 0.07, diastase 18.55 ± 2.97 un.Goethe the content of reducing sugars is 87.72 ± 1.96%, sucrose in the range of 0.6‒4.2%, with an average of 2.91 ± 0.81%. Conclusion. A comprehensive approach to the identification and evaluation of the quality of monofloral sunflower honey has been developed and the main criteria have been determined according to the degree of monoflorality (main pollen in the range of 45% and more), organoleptic and physicochemical indicators.
