0. Data Evaluation and Calculation
The chromatograms were evaluated (integrated) using Chromeleon software, and peaks were corrected manually when necessary. The obtained concentration values were directly transferred to the LIMS (Laboratory Information Management System) system. In addition, to evaluate the stability of the fermentation processes with a single parameter, the total value of all measured acids in terms of Acetic Acid Equivalent (Hac-Äquivalent) was calculated using the following formula:
