Palynological analyses, chemical and mineral composition of some honeybee pollen pellets

Abstract

Bee products have gained popularity in recent years as food, dietary supplements and adjuvant products due to their extraordinary health properties. Globally, bee pollen is the second most consumed product after honey, has a special importance as a male reproductive unit of flowers, as well as a rich nutrient material, as it contains the oral secretions of the honeybee. In this study, palynological identification of bee pollen collected from apiaries from different regions was made. The bee pollen content was found to be consisting of dry matter between 71.47-81.38%, protein between 17.5-26.0%, fat 5.84-10.95%, and ash content 2.02-2.44%. Moreover, the most common mineral elements in pollen were calcium, potassium, magnesium, silicium, sodium and iron. Besides, heavy metals such as arsenic, cadmium and lead have been detected in bee pollen samples that is a result of the increased environmental pollution and have negative effects on health. Therefore, in bee pollen production, identification, determination of nutritional quality and standardization of pollen are very important for producers and consumers.
