* The values represent the mean \(\pm\) standard deviation of triplicates. Different lowercase letters on the same row indicate samples with statistically significant differences at a confidence level of 95% (\(p<\) 0.05). B\(\_\)DW = bread with drinking water; B\(\_\)BMW = bread with bottled mineral water; B\(\_\)BMWns = bread with bottled mineral water without salt; B\(\_\)TWn = bread with thermal water; B\(\_\)TWn = bread with thermal water without salt. nd = not detected.
