The effect of roasting time and temperature on the flavan-3-ol and proanthocyanidin content and composition of cocoa. The levels of each compound were determined by HPLC-ECD and normalized to the concentration of the content of the individual compound in unroasted cocoa. Experiments were repeated 3 times. Data represent the mean of 3 experimental replicates. Error bars were omitted for clarity. Data were analyzed by two-way ANOVA with Bonferroni’s post-test. Summary statistics are shown in the figure.
