Comparative analytical study demonstrates distinct antioxidant profiles across floral honey types, indicating that antioxidant activity can determine botanical origin.

Key Points

To evaluate honey antioxidant capacity and total phenolics content via multivariate statistical analysis as biomarkers for classifying botanical honey varieties.
Tested N=90 varietal Polish honey samples across nine botanical types, including rape (12), tilia (10), goldenrod (11), dandelion (5), buckwheat (6), multifloral (17), nectar-honeydew (8), coniferous honeydew (16), and leafy honeydew (5).
Measured antioxidant capacity using photochemiluminescence (PCL; ACW and ACL kits) alongside reference DPPH and FRAP assays, and quantified total phenolics content (TPC) via the Folin-Ciocalteu method.
Performed principal component analysis (PCA) and hierarchical clustering to assess variety discrimination based on antioxidant profiles.
Buckwheat honey showed the highest antioxidant activity and rape honey showed the lowest across all tested analytical methods.
Antioxidant capacity assays showed strong positive inter-method correlation (r = 0.42 to 0.94), with PCL confirming that a minor fraction of honey antioxidants has hydrophobic properties.
Principal component analysis and clustering generated clear separation among honey varieties, demonstrating that antioxidant activity serves as an effective botanical indicator.
