| Abstract/Summary |
The lactic acid fermented cabbage juices were inoculated by Lactobacillus plantarum 92H at concentration 2.2 × 108 CFU cm−3 of juice. At the end of fermentation, the samples contained 14.49 g kg−1 of organic acids and 27.30 mg kg−1 of nitrates. The organic acids (expressed as lactic, acetic, and citric acids) were determined by capillary isotachophoresis. The suitable colour for juices was light-orange with medial turbidity. In the 72—96 h of fermentation, the juices had the most harmonic taste and flavour. From the correlation analysis it resulted that the highest values of correlation coefficients are between total acidity and pH (−0.98) and at the assessment of taste descriptors of juices, the highest correlation between sweet and acid (−0.97) was found. Principal component analysis reduced 15 sensory descriptors to 3 independent variables, which accounted for 79.80 % of total variance and 6 analytical descriptors, which accounted for 87.10 % of total variance.
