Functional quality assessment of bee pollen reveals key influences of botanical origin and phenolic composition.

To assess the functional quality of Spanish bee pollen samples by integrating various data types.
Combined palynological analysis, phenolic profiling, and antioxidant assays.
Constructed Phenolic Index (PI), Antioxidant Index (AI), and Global Functional Index (GFI).
Applied Spearman correlation analysis, principal component analysis (PCA), and one-way ANOVA for validation.
Strong correlations found between antioxidant indices and total phenolic content.
PCA identified a functional-antioxidant gradient influenced by botanical origin.
Samples from Castanea and Rubus showed higher functional indices, while Cistaceae samples were lower.

Rodríguez-Flores et al. (2026) studied this question.
