20.500.12556/RUL-186525 Routine quality parameters reflect metabolic organization in black chokeberry juice Black chokeberry juice is among the most phenolic-rich berry beverages; however, it remains unclear whether routine physicochemical quality parameters reflect its underlying metabolic organization. This study examined whether simplified quality measurements capture coordinated biochemical patterns in chokeberry juice. A comprehensive metabolite dataset, including primary metabolites (sugars and organic acids) and 46 individual phenolic compounds, was obtained using liquid chromatography-based methods. Routine quality parameters, including pH, total soluble solids (TSS), electrical conductivity, and UV–Vis absorbance at four wavelengths, were determined under standard conditions. The juice had high TSS (23.1 °Brix) and an acidic pH (3.55). Sorbitol, fructose, and glucose were the dominant sugars, while malic acid was the predominant organic acid. Total phenolics reached 9482 mg L−1, including 6801 mg L−1 anthocyanins. Multivariate analysis revealed a structured metabolic pattern characterized by a sugar–acid gradient and a coordinated phenolic axis, with anthocyanins forming a distinct pigment-related component. Stepwise regression indicated that TSS was associated with primary metabolic gradients, whereas pH was associated with structural phenolic organization. Canonical correlation analysis confirmed a shared latent dimension linking routine physicochemical parameters with metabolite-derived factors. These findings suggest that routine quality parameters reflect coordinated metabolic patterns within the investigated dataset and may support simplified quality assessment of phenolic-rich berry juices. chokeberry juice primary metabolites phenolic profile routine quality parameters multivariate data analysis aronija sok aronije primarni metaboliti kemična sestava bioaktivne spojine sekundarni metaboliti fenolne spojine true false true Angleški jezik Slovenski jezik Članek v reviji 2026-09-02 15:24:32 2026-09-02 15:24:39 2026-09-04 03:39:45 0000-00-00 00:00:00 2026 0 0 8 str. art. 109424 Vol. 158 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634 0889-1575 10.1016/j.jfca.2026.109424 289804547 1-s2.0-S0889157526005673-main.pdf 1-s2.0-S0889157526005673-main.pdf 1 7FCDE565FAB324D97ADD8F02566197B1 57b961c6b17fb8e4a5e33984363f3445c6d4fef4fbcaf70744e519fc4747880c 8bcaa06e-a6d1-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245798 https://www.sciencedirect.com/science/article/pii/S0889157526005673 1 40b5a137-a6d1-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245797 Biotehniška fakulteta 0 0 0
