Fig. 6 shows the concentrations of four groups of volatile compounds
(aldehydes, ketones, esters and alcohols) in the cocoa pulp and nibs
during fermentation of the 2012 beans in the absence and presence of
nisin + lysozyme. Similar data and conclusions were obtained for the
beans fermented in 2011 but were analyzed only for the fermentation
times 0, 72 and 144 h (Fig. S1).
