Microfiltration
The sugar cane juice with passion fruit pulp added
was microfiltered in a pilot filtration unit, using tangential
flow and an organic polyimide membrane
(PAM Membranas Seletivas, Rio de Janeiro, RJ, Brazil)
in a hollow fibre configuration, with an average
cross-section diameter of 0.4 lm and a filtration area
of 0.7 m2. The following operating conditions were
used in the microfiltration: temperature, 45 ± 1 °C;
transmembrane pressure, two bars; and tangential
velocity, 0.87 m s
1. These parameters were based on
preliminary studies. After each microfiltration test, the
equipment and the membrane were sanitised, according
to the manufacturer’s instructions
