PENGARUH PERBANDINGAN AIR KELAPA TUA DENGAN SARI SIRSAK DAN KONSENTRASI NATRIUM BIKARBONAT (NaHCO3) TERHADAP MUTU MINUMAN AIR KELAPA BERKARBONASI
ABSTRACT: The objective of
this research was to find out the effect of ratio of old coconut water with
soursop juice and concentration of natrium bicarbonate (NaHCO3) on the quality
of carbonated coconut water. This research was conducted in December 2015 –
January 2016 in the Laboratory of Food Technology, Agriculture Faculty, North
Sumatera, Medan, using Completely Randomized Design (CRD) with two factors, i.e.
ratio of old coconut water with soursop juice (K) (60%:40%; 70%:30%; 80%:20%;
90%:10%) and concentration of natrium bicarbonate (NaHCO3) (N) (0,4%; 0,5%;
0,6%; 0,7%). The results showed that ratio of old coconut water with soursop
juice had highly significant effect on vitamin C content, total acid, pH value,
total soluble solid (TSS), ash content, score value of taste, and hedonic value
of taste. Concentration of natrium bicarbonate (NaHCO3) had highly significant
effect on vitamin C content, total acid, pH value, CO2 content, ash content,
score value of carbonated effect, and hedonic value of taste. The interaction
of ratio of old coconut water with soursop juice and concentration of natrium
bicarbonate (NaHCO3) had highly significant effect on vitamin C content.
