| description | Chokeberries are a subject of numerous studies due to a high phenolic compound content, antioxidant properties and potential positive influence on the health. Effects of weather conditions on fruit quality attributes, phenolic compounds and antioxidant capacity of chokeberry (Aronia melanocarpa) juice over three consecutive years were investigated. Total phenolic content and total flavonoids range were from 8834 to 11093 mg/L and from 6993 to 9710 mg/L, respectively. High variations and discrepancy during different growing seasons are due to the different air temperature, sunlight and rainfall rate. The highest concentrations of anthocyanins and phenolics were observed in fruits harvested in 2012, which is most likely due to the favorable weather conditions (temperature and bright sunshine hours). All chokeberry juices possess high antioxidant activity (12.9–14.6 mmol/L; 128–167 mmol/L). Strong correlation implies that flavonoids and non-flavonoids were the major contributors to the antioxidant capacity. This study indicates that although the examined properties vary considerably through the growing seasons (p≤0.05), chokeberry juices can serve as a good source of bioactive phytochemicals in a human diet. |
