Abstract

Objective
Bee pollen is an essential source of nutrition for honeybees. In addition, bee pollen has biological properties such as antioxidant, antibacterial, antifungal, immune modulator, antitumor, anti-aging, anti-anemia and anti-osteoporosis. This study was conducted to identify the diversity of flavor compounds in bee pollen and their effect in attracting worker honeybees within the colony.
Materials and methods
Three types of bee pollen were collected from honeybee colonies during different seasons using pollen traps installed at the hive entrances. The extraction of flavor compounds from bee pollen grains was carried out. Gas chromatography-mass spectrometry (GC-MS) was performed on a fused silica capillary column with specifications. The completely randomized design (CRD) was used for data analysis.
Results
The results showed a diversity in flavor compounds in the three types of bee pollen and a difference in the proportions of their components. Type A of bee pollen was unique in that it contained its own flavor compounds that were not available in the other two types, B and C, and vice versa. Several compounds were detected at similar retention times in the three pollen types, while these compounds differed in their proportions according to the type of bee pollen grain. Among the most important compounds that appeared in the three types of bee pollen grains were 9,12-octadecadienoic acid (Z,Z), n-hexadecanoic acid, 4H-pyran-4-one, γ-sitosterol, linolenic acid derivatives, and campesterol. In addition to similar compounds that appeared in small proportions. Regarding the effect of flavor compounds in attracting worker honeybees while feeding on them, the results of the statistical analysis (P≤0.05) showed no significant differences between the averages for the three types of bee pollen.
Conclusion
Our results highlight the importance and utility of pollen flavors in bee nutrition and behavior. The more we understand about the chemical composition of bee pollen and its role in honey bee attraction, the better we can help improve artificial diets and pollen substitutes used in beekeeping practices.
