The specific taste related to the extract (bitter and caramel/
burnt) increased with increasing extract concentration for both
purees (Table 4). Higher extract concentrations also increased
astringent, bitter and burnt aftertastes. Such result is not surprising
since both astringency and bitterness are elicited by polyphenolic
compounds of which monomeric phenols are more bitter than
astringent, whereas the reverse is true for larger molecular weight
derivatives (Brossaud, Cheynier, & Noble, 2001). Furthermore, we
assume that ellagitannins, ellagic acid and some other phenolic
