description

Abstract Honeyberries are rich in various nutrients (eg. minerals, and vitamins) and bioactive compounds (eg. polyphenols). The aim of the study was to evaluate the impact of ultrasound (USN) pre-treatment (100% power at 37 kHz) at 40 °C for 3 min and drying techniques (conduction or vacuum) on nutritional composition and bioactive compounds of honeyberry fruits. The evaluation of dried barriers revealed that both USN pre-treatment and drying techniques affected the composition of the final product. The highest vitamin C content (1.067–1.187 mg 100 g−1 DM) was found in fruit samples pre-treated by USN, regardless of the drying technology used. The highest total phenol (2.445 mg GAE 100 g−1 DM), total flavonoid (0.939 mg GAE 100 g−1 DM), total non-flavonoid (1.506 mg GAE 100 g−1 DM) and anthocyanin content (2.334 mg kg−1 FW) were obtained in fruits after applying USN pre-treatment and vacuum dried at 40 °C.
