Protein content and amino acid composition of bee-collected pollen from selected botanical origins

Journal of Apicultural Science. Volume 50, Issue 2, Pages 81-90, ISSN (Print) 1643-4439
The objective of the study was to investigate the protein and amino acid composition of honeybee-collected pollen from selected botanical origins. The following unifloral pollen samples were selected and analysed: Onagraceae, Caryophyllaceae, Artemisia, Agrimonia, Rheum, Cornus, Fragaria, Syringa, Ranunculus, Majorana type, Brassica, Sinapis alba, Sinapis arvensis, Campanula patula, Chelidonium maius, Polygonum bistorta.
The concentration of amino acids and crude protein content was dependent on the floral origin of pollen. Pollen from plants belonging to Brassicaceae family (Brassica, Sinapis arvensis, Sinapis alba) and Chelidonium maius pollen was characterized by high content of crude protein and amino acid concentration. Artemisia and Polygonum bistorta pollens were characterised by a low content of these components. The concentration of essential amino acids expressed as percentages of total amount of amino acids was relatively stable and not dependent on the botanical origin of pollen. Pollen belonging to ruderal plants, especially Sinapis arvensis, Sinapis alba and Chelidonium maius is an important source of protein and amino acids for bees and for human purposes.
