### Acidity and Microbiological and Chromaticity Characteristics of Lentil Wholemeal Samples
On the other hand, glutamic acid, aspartic acid, glycine, alanine, proline, and tyrosine showed negative correlations with lentil samples' pH (r = \(-\)0.828, \(p\) < 0.001; r = \(-\)0.758, \(p\) < 0.001; r = \(-\)0.431, \(p\) = 0.009; r = \(-\)0.360, \(p\) = 0.031; r = \(-\)0.608, \(p\) < 0.001; and

r \(=-0.442\), \(p=0.007\), respectively) and negative correlations with LAB count (r = 0.869, \(p\) < 0.001; r = 0.794, \(p\) < 0.001; r = 0.369, \(p\) = 0.027; r = 0.329, \(p\) = 0.050; r = 0.472, \(p\) = 0.004; and r = 0.433, \(p\) = 0.008, respectively). The significance of analysed factors and their interactions on FAA and GABA concentrations are presented in supplementary file: Table S3. The growing conditions factor was statistically significant for almost all nonessential FAA concentrations, except for glycine and alanine. The type of fermentation factor was statistically significant for all nonessential FAA concentrations.
