In-vitro bioaccessibility of antioxidant properties of bee pollen in Turkey

Abstract The study aims to determine certain physicochemical properties (moisture, ash, titratable acidity, pH, and color), total phenolic content, antioxidant capacity (CUPRAC, ABTS, DPPH) and bioaccessibility of 20 bee pollen samples (10 unpackaged and 10 trademarked products in their original packages) sold in Turkey. The total phenolic content of the bee pollen samples was detected as 147.10-462.02 mg GAE/g and bioaccessibility ranged from 36.91% to 77.87%. The highest total value for antioxidant capacity was assessed as 83.24-257.27 μmol TE/g by the CUPRAC method. When the bioaccessibili...
