•Cranberry products were characterized by a high content of bioactive compounds.•Pomaces obtained from crushed fruits are the most valuable in polyphenols.•Products obtained from crushed fruits had a higher content of bioactive compounds.
The aim of the study was to evaluate the effect of the degree of fragmentation of cranberry fruit (Vaccinium macrocarpon L.) on the chemical composition and antioxidant activity of fruit powders and lyophilized pomace and juices. In analyzed samples, the basic chemical composition, total polyphenolics and antioxidant capacity were determined. Thirty-nine polyphenolic compounds, including 9 phenolic acids, 7 anthocyanins, 9 flavan-3-ols and 14 flavonols, were identified. Polyphenolic concentrations in pomaces ranged from 16 038.74 mg/100 g DW in samples from whole fruits to 17 802.52 mg/100 g DW in samples from crushed fruits. In juices, phenolic concentrations ranged from 873.12 mg/100 g DW in products from whole fruits to 3177.87 mg/100 g DW in products from crushed fruits. Antioxidant capacities were higher in dry products than in juices. The highest DPPH, ABTS and FRAP values were determined in dry pomaces obtained from crushed fruits (156.94, 275.22 and 71.47 μmol/g DW, respectively).
