| Summary: | This study was conducted to evaluate some physicochemical parameters of underutilized tropical fruit
namely belimbing dayak (Baccaurea angulata). Several parameters were identified including pH, total
soluble solid (TSS), titratable acidity (TA), sugar-acid-ratio (TSS:TA), ash and calcium composition at
different concentrations and conditions of belimbing dayak juice. The conditions are juices without addition
of sugar and juices added with sugar. These juices were prepared at concentrations of low (LC), medium
(MC) and high (HC). The highest pH was observed in LC added with sugar (3.43) while the lowest pH can
be detected at HC with sugar (3.03). The TSS value vary widely where the highest TSS value for juices
without sugar was 1.05°Brix while for the juices with sugar the highest TSS value was 7.95°Brix. TA
readings pattern was observed to be increase as the concentration increasing for both conditions. From the
analysis of ash, the content for both conditions are the same where the reading for LC and MC was
0.02g/100ml of juice and for HC the value was 0.05g/100ml of juice. Most of the parameters interested
showed statistically difference (p<0.05). The calcium content was ranging from 4.88 to 10.96mg/L. The
results contribute to the important information on physicochemical properties of belimbing dayak.
