Abstract:
This study aimed to analyze physicochemical characteristics and phenolic profile of twenty-three sweet cherry cultivars from Fundão region, Portugal. The average length and width ranged between 1.9 and 2.6 and 2.1-2.8 cm, respectively. Weight varied between 4.9 and 11.8 g, firmness ranged from 7.3 to 20.1 N, moisture and ash contents ranged from 75.1 to 88.6% and 0.4 to 2.9%, respectively. Sunburst and Sweetheart presented high values of CIEL∗, a∗ and b∗, and low values regarding total soluble solids and maturity index. A total of 46 phenolic compounds were identified by HPLC-DAD-ESI/MSn and quantified by HPLC-DAD, namely 19 hydroxycinnamic acids, 2 hydroxybenzoic acids, 13 flavonols, 5 flavan-3-ols, 2 flavanones, 1 flavanonol and 4 anthocyanins. Sunburst and Brook's were the richest in non-colored phenolics, while Garnet and Tavora were the richest ones in anthocyanins. Therefore, our results revealed that sweet cherries represent a supply of high-value bioactive compounds, being greatly influenced by the cultivar.
