Samples of three types of honey: polyfloral (PH), linden (LH) and acacia (AH,) without and with addition of dried cherries (40%) were analyzed before and after three months of storage. The total phenol (TPh), flavonoid (TFd) and anthocyanin (TAn) contents, antioxidant activities and sensory properties of honeys with and without the addition of dry cherries were evaluated. TPh and TFd increased with addition of dried cherries to the honey, while enriched honeys showed high TAn. The LH sample with dried cherries showed the highest anthocyanins content (41.41mgCGE/100g). The antioxidant activity increased with addition of dried cherries in honey in the DPPH• test and reducing power. The PH and DPPH enriched PH exibited the best antiradical activity compared to LH and AH. The EC50 values were: 23.81 for PH and 24.19 mg/mL for PH, while the EC50 DPPH were: 1.16 mg/mL for PH40 and 1.18 mg/mL for PH40s. RP0.5 values were: 57.00 mg/mL for PH40 and 56.00 mg/ml for PH40s, while RP0.5 were: 15.05 mg/mL for PH40 and 15.18 mg/mL for PH40s. The statistical analysis showed that TPh, TFd and TAn, and antioxidant activity of honeys and enriched honeys showed significant correlation. Sensory analysis of honey with dried cherries, before and after storage, indicated very good sensory characteristics.
