To evaluate the stability and degradation pathways of major chokeberry polyphenols across individual juice processing steps and during six months of ambient storage.
Tracked concentrations of anthocyanins, total proanthocyanidins, hydroxycinnamic acids, and flavonols at distinct stages of chokeberry juice processing, including pressing and thermal treatments.
Assessed polyphenol retention and polymeric color changes in processed chokeberry juice throughout six months of storage at 25 °C.
Flavonols, total proanthocyanidins, and hydroxycinnamic acids showed strong stability through manufacturing and 6 months of storage, with primary processing losses restricted to pomace removal after pressing.
Anthocyanins degraded substantially during heat treatments—coinciding with increases in protocatechuic acid and phloroglucinaldehyde—and experienced progressive, linear degradation during 6-month storage accompanied by increased polymeric color values.

Implication

Experimental analysis demonstrates differential degradation of chokeberry polyphenols during juice processing and storage, indicating significant thermal and temporal sensitivity of anthocyanins.
