but prolonged processing (20 min) under the same pressure and temperature gave the TP content
as 30.5 GAE/100 mL beverage.
It can be concluded that at higher pressures, more phenols are extracted from the tissues and hence, they become readily susceptible to
the degradation effects of high temperatures with an increase in dwell
time. Therefore, the combination of high pressure at higher temperatures (like 70 °C) resulted in the deterioration of the total phenols in
the beverage samples.
