"Supplier B has provided three cocoa liquor samples that were compared with traditional cocoa samples received. Results are shown on Table 1. The difference between samples B1 and B2 was the roasting process. B1 uses continuous roasters and B2 is roasted in batches. It seems that the continuous process is less aggressive to flavonoids than the batch roaster. One hypothesis is that in batch roasters the beans are heated in a non uniform way what damages more the flavonoids than other polyphenols that are on the samples."
