2. Materials and methods
2.1. Sample preparation
Pomegranates (Punica granatum L. cv Malase Saveh) were
purchased from a local market in Tehran, Iran and stored at
refrigeration conditions (4 C) prior to experiments. They were
washed in cold tap water, drained, and then manually cut into
four or six pieces. The juice was then extracted by pressing the
samples with manual press at a pressing pressure of 11.25 kPa
for 10 min and 62.5 kPa for 5 min (Vardin and Fenercioglu,
2003). Large particles in the juice were removed using a No.
9 mesh filter. The properties of the pomegranate juice at room
temperature before the ohmic heating are listed in Table 1.
These values are similar to those observed in the literature
for pomegranate juice by Ghourchi and Barzegar (2009),
Akbarpour et al. (2009); and Vardin and Fenercioglu (2003).
