with the darker color of gels with either extract at higher
levels. These results were in agreement with O’connell and
Fox (2001) who reported that phenolic compounds were
responsible for discoloration in cheese products. The polymerized phenolic compound, especially tannin with its dark color
most likely contributed to the dark color of gels. At the same
level of extract used, gels with EKWE showed a darker color
and lower redness, compared with those with ECBE (po0.05).
