When
Wang and Zhou (2004) studied green tea extract in bread
making, they concluded that the extract could be used at a
level of 150 mg/100 g flour with no color acceptability
problems. Colahan-Sederstrom and Peterson (2005) found
that UHT milk processed with 3 levels of EC (0.01%,
0.1%, and 0.2%) had significantly less cooked flavor than
the corresponding UHT control milk sample. However the
0.2% EC milk sample had a significantly higher level of
bitterness.
