Factors Affecting Quality of Honey Bee Venom

Abstract

Abstract Honeybee venom (HBV) is an important product of beehives, and its benefits for health have been rediscovered by modern medicine. Since HBV has the potential to treat some diseases, its quality and production conditions require a detailed investigation. The objective of this study is to understand how season, harvesting time (day or night), harvesting site of beehives (inside or entrance) and geographic location affects quality through the analysis of apamin, melittin and phospholipase A2 (PLA2) content. Each set of six colonies were used to understand the differences in these components when HBV is harvested in the daytime either from the entrance or inside of the hives and nighttime from the inside of the hives. The experiment also investigated seasonal differences as the samples were harvested each month from May to August 2019 in our apiary. Furthermore, the effect of geographic location on quality was examined through the comparison of the data obtained from twenty-seven samples collected by beekeepers using the same device, located in the Turkish cities of Manisa, Muğla, Balıkesir, Düzce and Mersin. The results demonstrated that statistically significant differences in the amounts of analyzed components were not dependent on harvesting time, collection site on the beehives or season. On the other hand, region samples significantly differed in the amounts of all three components, ranging from 1.28% to 3.81% for apamin, 19.51–64.03% for melittin and 7.22%–28.18% for PLA2. However, beekeepers’ improper practices during harvesting and storing might be the most critical parameters that determine the quality of HBV.
