Pembuatan Minuman Probiotik Sari Melon Menggunakan Lactobacillus Plantarum 1 Rn2-53 Dengan Konsentrasi Sukrosa Yang Berbeda
ABSTRACT
Sucrose is one of the energy sources to support the growth of
Lactobacillus plantarum 1 in the manufacture of melon juice probiotic drinks. The
purpose of this research was to get the best addition of sucrose in the making
melon juice probiotic drinks using Lactobacillus plantarum 1 RN2-53. This study
was conducted experimentally using a completely randomized design with five
treatments and three replications. The treatments consisted of P1 (without addition
of sucrose), P2 (addition of sucrose 2% from the volume of melon juice), P3
(addition of sucrose 4% from the volume of melon juice), P4 (addition of sucrose
6% from the volume of melon juice) and P5 (addition of sucrose 8% by volume of
melon juice). Data were analyzed statistically using analysis of variance
(ANOVA), if Fcount ≥ Ftable then, continue with Duncan's new multiple range
test (DNMRT) at the 5% level. The results showed that the addition of various
concentrations of sucrose significantly affected the degree of acidity (pH), total
lactic acid, total lactic acid bacteria, total solids, and descriptive assessment of
color, aroma, and taste as well as hedonic sensory assessment. Based on this
research, the best treatment obtained was P4 (addition of 6% sucrose from the
volume of melon juice) with a degree acidity (pH) of 3.67, total lactic acid 0.55%,
total lactic acid bacteria 8.42 log CFU/ml, total solid 7.79% and a description of
bit green color, distinctive fermentation aroma, sour and sweet taste, and the
overall assessment was somewhat favored by the panelists.
