Fermentation and Sensory Analysis

The jabuticaba fermented beverage, or jabuticaba wine, shows certain sensorial properties similar to those of red wine. Here, a comprehensive bromatological analysis of seven artisanal jabuticaba wines (JW1-7) revealed different physicochemical and color properties. Among the samples, JW6 stood out for having the highest content of monomeric anthocyanins (28.8 mg/L) and minerals, such as K (1594.58 μg/mL) and P (49.89 μg/mL). Surprisingly, the Cu content found in all samples exceeded the maximum limit established for this metal in wines. Using NMR-based metabolomics, more than 100 compounds were identified, most of them were carbohydrates. Furthermore, a discriminant analysis of the metabolomic data by PCA revealed that the contents of sucrose, glucose, stachyose and quinic acid enabled the differentiation of the wines and wine producers. The results presented here pave the way for further investigations into the composition of jabuticaba wines and their impact on product quality.
