ABSTRACT
Bee pollen belongs to bee products that are characterized by high nutritional value and biotic activity.
These characteristics result from the wide variety of compounds that bee pollen contains.
Our study determined the effects of storage conditions of bee pollen extracts on polyphenol content. The study was conducted with the use of three types of bee pollen extracts, namely ethanol extracts, enzymatic hydrolysates from pollen, and ethanol extract of pepsin-digested bee pollen. Polyphenol content in the studied extracts was determined immediately after extraction and after 12-month storage. We have concluded that 12- month storage of bee pollen extracts decreases polyphenol concentration in all three types of extracts, and the changes depend on the storage conditions.
