Karakteristik Kefir Air Semangka Dengan Variasi Konsentrasi Starter Dan Lama Fermentasi

Water kefir is a probiotic drink fermented from kefir grains with a mixture of water, fruits, and sugar. Watermelon is one fruit that could be used as a raw material for water kefir. The purpose of this study was to determine the interaction between starter concentration and fermentation time on the characteristics of watermelon water kefir. The research was conducted experimentally using a factorial complete randomized design (CRD) with six treatment interactions and three replicates so that 18 experimental units were obtained. The treatments in this study were starter concentration (K) and fermentation time (F) and their interactions, namely K1F1 (4% and 12 hours), K2F1 (7% and 12 hours), K3F1 (10% and 12 hours), K1F2 (4% and 24 hours), K2F2 (7% and 24 hours), and K3F2 (10% and 24 hours). Data were analyzed statistically using analysis of variance (ANOVA), if Fcount> Ftable then continued with Duncan's multiple range test (DMRT) at the 5% level. The results showed that interaction of variations in starter concentration and fermentation time significantly affected total lactic acid bacteria, acidity (pH), total titratable acid, total yeast, alcohol content, and total soluble solids. The selected treatment based on the parameters tested was K3F2 treatment (starter concentration of 10% and fermentation time of 24 hours) which has met the quality standards of kefir CODEX STAN 243-2003 with a total value of lactic acid bacteria 9.30 CFU/ml, pH 3.48, total titratable acid 1.59%, total yeast 6.40 CFU/ml, alcohol content 0.40%, and total soluble solids 3.98ºBrix.
Keywords: water kefir, watermelon, starter concentration, fermentation time
