Cleaning-in-place (CIP) of pink guava puree (PGP) fouling deposits is not well known compared to dairy deposits which is well established. Lab-scale cleaning test rig has been used to investigate the cleaning performance of PGP deposits. Removal mechanism during alkaline-based cleaning of PGP deposits were investigated using NaOH concentrations (1.0 wt% - 2.0 wt%), temperatures (35 - 70 degrees C) and fluid velocities (0.6-1.5m/s) over a range of Reynolds number (Re=4x10(4) - 1.8x10(5)). Cleaning rate was quantified by measuring the remaining area of the deposits at sample holder at every 1min. The efficient CIP process for PGP fouling deposit can be obtained at 1.5m/s, 70 degrees C, with concentration of (1.0 - 2.0wt%). (C) 2014 The Authors. Published by Elsevier B.V.
