Abstract
Progressive Freeze Concentration (PFC) was applied to concentrate coconut water (CW) in order to enhance its sugar
content. In PFC system, only a single ice is formed as a sheet on the cooled surface. It is introduced as an alternative in compensating the disadvantages of conventional method of Freeze Concentration (FC), called Suspension Freeze
Concentration (SFC). In this research, the efficiency of the PFC system was determined through Effective Partition Constant (K) value and percent increment of sugar content. Hence, the effect of circulation flowrate and circulation time on those two variables was then investigated. From the experimental work, it was found that higher efficiency results at higher circulation flowrate of 2800 ml/min based on lower K and high percentage of sugar increment achieved. It was also found that the percentage of the sugar increment is high when the period given for circulating the solution is increased and the most suitable circulation time is 14 minutes.
