RESUMEN

Climate change affects plant phenology and, as a result, can damage nectar and pollen sources, which are the basic needs of bees during flowering. This situation creates nutritional stress for bee colonies in the region. Changing climatic conditions, the use of agricultural lands adversely affects honeybees and beekeepers. The aim of this study is to determine the annual development performance of fixed honeybee colonies linked with the chemical and mineral profile of bee collected pollen. According to the research findings, in terms of colony development parameters, the number of bee frames (9.17) was found to be at the highest level in May, and in terms of brood area (4652.35 cm2 ) in April (P<0.05). March, April, and May are the most abundant months in terms of pollen collection of the colonies (P<0.05). The pollen samples collected are rich in potassium, sodium, calcium, magnesium, silicon, and iron. There are differences between months in terms of pollen sources and mineral levels. Especially in stationary beekeeping, additional feeding is required during critical periods. The existing flora is insufficient for the future of the honey bee. In periods when the flora is weak, important plants for the honey bee should be grown in the region.

RESUMEN

INTRODUCTION: Mad honey is widely used in folk medicine in the Black Sea region of Turkey for its medicinal properties, but its pollen is not collected by mad honey producers and its benefits are unknown. METHODS: In this study, water and ethanol extracts of mad honey bee pollen from four different plateaus in the Black Sea region of Turkey were researched for their antioxidant and antimicrobial properties. Phytochemical analyses were carried out and the data were supported with UV-Vis spectrophotometry. Antimicrobial activity was researched against four Gram-positive and four Gram-negative bacteria, one fungus, and one yeast. The results were compared with standard antioxidants and antibiotics. RESULTS: The ethanol extracts of the samples from Sinop (P5), Giresun (P7), and Trabzon (P8) were the most active samples as antioxidants, and almost all the extracts of R. ponticum bee pollen were effective on the tested microorganisms. However, P5-8 showed better values for B. cereus, E. feacalis, E. coli, and P. aeruginosa. CONCLUSION: It has been proven that mad honey bee pollen is a natural product with previously unknown medicinal properties and rich phytochemical content. Future research and clinical trials are important to scientifically support its benefits in complementary medicine.

RESUMEN

This study was performed to investigate the physicochemical quality characteristics of honey produced in Southeastern Anatolia of Turkey. A total of 68 honey samples collected from different beekeepers were analyzed for sugar components, moisture, pH, HMF, electrical conductivity, free acidity, proline values, and diastase number using the methods recommended by the International Honey Commission. The color value was determined by the Hanna HI 96785 color identification device using the Pfund scale. The mean values of fructose + glucose, fructose/glucose ratio, sucrose, and maltose were 70.97 ± 3.27%, 1.21 ± 0.15, 0.90 ± 1.35%, and 2.88 ± 1.42%, respectively. The moisture, pH, electrical conductivity, free acidity, diastase number, proline, and HMF values were 15.91 ± 1.05%, 4.10 ± 0.73, 0.21 ± 0.04 mS/cm, 14.94 ± 6.81 meq/kg, 10.68 ± 4.61, 420±, 174 mg/kg, and 18.5 ± 31.43 mg/kg, respectively. All of the samples met the international standards and legal limits set in Turkey for fructose + glucose, sucrose, moisture, electrical conductivity, and free acidity, whereas 20.58%, 25%, 10.29%, and 8.82% of the samples did not meet the standards and legal limits for the diastase number, proline value, HMF value, and fructose/glucose ratio, respectively. It has been considered to be important to raise awareness of the producer about good production practices and to ensure continuity of inspections for high-quality honey production.
