20.500.12556/RUL-181321 Impact of pulsed electric field pretreatment on quality parameters of aronia and haskap berry juices This study examined the effect of pulsed electric field pre-treatment at three intensities (1.78, 5.3, and 10.7 kJ/kg) on the yield and physicochemical properties of aronia and haskap juices. PEF significantly increased juice yield by 18.0% points in aronia (from 39.3% to 57.3%) and 30.6% points in haskap (from 29.2% to 59.8%) at 10.7 kJ/kg. Physicochemical properties were also affected: pH, total soluble solids, and viscosity increased, while both juices retained pseudoplastic flow behaviour. PEF induced significant colour changes, with total colour difference increasing progressively with treatment intensity. PEF enhanced sugar extractability, increasing total sugars from 169.4 to 210.0 g/L in aronia (mainly glucose and sorbitol) and from 115.2 to 142.1 g/L in haskap (mainly glucose and fructose). Organic acids increased by 26-27%, with higher citric, malic, and quinic acids. Phenolic compounds, especially anthocyanins, increased from 8.60 to 15.12 g/L in aronia and from 5.65 to 10.18 g/L in haskap, along with increases in flavonols and total phenolics. Correlation analysis revealed strong positive relationships between juice yield, sugar content, total acids, and phenolic compounds in aronia, while moderate positive correlations were observed between these parameters in haskap. Overall, PEF at 10.7 kJ/kg effectively improved yield and compositional quality of both aronia and haskap juice. non-thermal processing fruit juice bioactive compounds anthocyanins extraction berries sadni sokovi jagodičevje bioaktivne snovi antocianini ekstrakcija netermična obdelava true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-01 08:51:10 2026-04-01 08:51:16 2026-04-02 04:25:56 0000-00-00 00:00:00 2026 0 0 17 str. art. 150 Vol. 252 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 543 1438-2377 10.1007/s00217-026-05081-0 273811203 Puzovic-2026-Impact-of-pulsed-electric-field-pre.pdf Puzovic-2026-Impact-of-pulsed-electric-field-pre.pdf 1 96B134177500980E03CB1AAFCE94BDAF 95970c59a07df89a34ab56dc4f708333f11b41ee4e87e638e5ae8f06cce1a8c9 44011745-2d97-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231684 https://link.springer.com/article/10.1007/s00217-026-05081-0 0 07d52d9a-2d97-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=231683 Biotehniška fakulteta 0 0 0
