Quality Evaluation of High-Polyphenol Vinegars Produced from Various Romanian Plum Cultivars

Plum vinegar represents a functional food product valued for its potential health ben- efits, largely attributed to its polyphenolic content. This study investigates the quality parameters of vinegars produced from five Romanian plum varieties (Centenar, Agent, An- dreea, Anna Spath and Romanian Vanata), focusing on their physicochemical and phenolic profiles. Analyses included pH, total acidity, colorimetric evaluation, total polyphenolic content (TPC), antioxidant activity, and ATR-FTIR and...
