Pemanfaatan Lactobacillus plantarum 1 RN2-53 Dalam Produksi Jus Kentang Ungu Synbiotic

---

Purple sweet potato is a source of prebiotics that can be used in making synbiotic drinks by adding probiotics in the form of lactic acid bacteria (LAB), one of which is Lactobacillus plantarum 1 RN2-53. The purpose of this study was to obtain the best concentration of starter Lactobacillus plantarum 1 RN2-53 in the manufacture of purple sweet potato extract synbiotic drink. This study was conducted experimentally using a completely randomized design with four treatments and four replications. The treatments used were S1 (starter concentration Lactobacillus plantarum 1 RN2-53 2%), S2 (starter concentration Lactobacillus plantarum 1 RN2-53 4%), S3 (starter concentration Lactobacillus plantarum 1 RN2-53 6%), and S4 (starter concentration Lactobacillus plantarum 1 RN2-53 8%). The data obtained was analyzed statistically using the analysis of variance test and followed by duncan's multiple range test at the 5% level. The results showed that the various concentration of LAB starter significantly affected on the degree of acidity (pH), total lactic acid, total LAB, antioxidant activity, and descriptive and hedonic sensory tests, as well as the overall assessment. The selected synbiotic drink treatment in this study was treatment S2 (starter concentration Lactobacillus plantarum 1 RN2-53 4%) with a pH value of 3.66, total lactic acid 1.13%, total LAB 10.60 log CFU/ml, and antioxidant activity 58.31 ppm, with a characteristic purple color, slightly fermented aroma, slightly sour taste, watery texture, and overall the panelists liked it.
