Acid concentrations were measured in duplicate (n = 2); results are expressed as mg/L ± standard deviation; LOD (limit of detection) defined as ≤29 mg/L; (+) low degradation; (++) intermediate degradation; (+++) strong degradation based on MALDI-TOF MS spectra interpretation; LAB (lactic acid bacteria); GBM (gluten-based medium); FAN (free amino nitrogen).
