Hungarian fruit vinegars were analyzed in terms of physicochemical attributes, sensory profiles, and antimicrobial properties. The composition and sensory profiles of different types of vinegar and additional fruits showed distinct patterns. Vinegars matured on rosehip, sea buckthorn, and raspberry exhibited outstanding antioxidant performances. Rosehip, raspberry, quince vinegars, as well as vinegars produced from Tokaji aszu and balsamic apple obtained high scores for fruity and sweet notes. Antimicrobial activities were generally weak, but more pronounced inhibitions were observed for probiotic strains.
Hungarian fruit vinegars were characterised in terms of physicochemical attributes (total polyphenol solids), sensory profiles, and antimicrobial properties. Both compositional and sensory profiles showed distinct patterns depending on the type of vinegar (Tokaj wine, balsamic or apple) and the additional fruit used. Balsamic vinegars maturated on rosehip, sea buckthorn, and raspberry showed outstanding antioxidant performances. Rosehip, raspberry, and quince vinegars, as well as vinegars produced from Tokaji aszu and balsamic apple obtained high scores for fruity and sweet notes. Antimicrobial activities were tested on Gram-negative and Gram-positive organisms, including probiotic bacteria. Generally, only weak activities were obtained, which was attributed to the natural sugar content of the samples, depending on the type of the vinegar and the fruit. Similar results, but more pronounced bacterial growth inhibitions were obtained for probiotic strains, however, some probiotic strains were resistant to at least two of the vinegars. Based on these, balsamic apple, raspberry, rosehip,
