ABSTRACT
The purpose of this research was to obtain the best and appropriate
concentration of red dragon fruit peel extract as a natural dye to improve the quality
of soursop probiotic drink by utilizing Lactobacillus plantarum 1 RN2-53. This
research was conducted experimentally using a completely randomized design with
five treatments and three replications to obtain 15 experimental units. The
treatments in this study consisted of N1 (addition of red dragon fruit peel extract
5%), N2 (addition of red dragon fruit peel extract 10%), N3 (addition of red dragon
fruit peel extract 15%), N4 (addition of red dragon fruit peel extract 20%) and N5
(addition of 25% red dragon fruit peel extract). The results showed that addition of
red dragon fruit peel extract with different concentrations significantly affected the
chemical, microbiological, physical and organoleptic assessment of soursop juice
probiotic drinks. Based on the research, the best treatment was obtained from N5
treatment (addition of red dragon fruit peel extract 25%) with the criteria of 3.88
pH value, 0.71% titrated acid total, 9.22 log CFU/ml total LAB, 24.19 color test
value L*, 4.09 color test a*, and -2.65 color test b*. Sensory characteristics
descriptively of the N5 treatment showed a purple color, and had a characteristic
