Three other organic acids, malic, succinic and oxalic, were found in
the pulp and nibs of our beans. The profiles of their changes were not affected
by LAB. We draw attention to the relatively high concentration of
succinic acid in pulp and nib fractions and its increase during fermentation.
Its significance to the process and chocolate quality has, previously,
been overlooked. The utilization of pulp malic acid during fermentation
might be due to P. kudriavzevii which is a strong utilizer of this acid (Kim
et al., 2008).
