Abstract
Bunga telang merupakan tanaman yang umum ditemukan di Indonesia yang
diharapkan dapat meningkatkan nilai fungsional antioksidan dengan dijadikan
kombucha. Penelitian ini bertujuan untuk menentukan aktivitas antioksidan,
flavonoid, fenolik, pH, dan total asam tertitrasi yang optimal pada kombucha bunga
telang dengan penambahan air seduhan bunga telang dan gula. Dari berbagai variasi
penambahan air seduhan bunga telang dan gula, kombucha bunga telang dengan
perlakuan konsentrasi seduhan bunga telang 0,5% dan konsentrasi gula 30%
merupakan perlakuan terbaik dengan nilai pH 2,71, nilai total asam tertitrasi
0,35%, aktivitas antioksidan IC50 123,77 ppm, dan total fenolik dan konsentrasi
flavonoid sebesar 24,93 mg QE/L dan 135,64 mgGAE/L. Dalam penelitian ini
ditemukan adanya perubahan sifat kimia dan kandungan antioksidan dari kombucha
dengan ada nya penambahan air seduhan bunga telang dan gula. / Peaflower is a flowering plant found to Indonesia can be increased its antioxidant
functional value by making it into kombucha. The research is focused on the
antioxidant activity, phenolic content, flavonoid content, pH, and total titrable acids.
By adding variations of peaflower tea and sugar concentration can be found that
kombucha with 0,5% tea concentration and 30% sugar concentration gives the best
treatment with pH 2,71, IC50 123,77 ppm total titrable acidity score 0,35%, and
flavonoid and phenolic value as much as 24,93 mg QE/L and 135,64 mg GAE/L.
This research also found there is an affect on the chemical properties and
antioxidant of kombucha through the addition of peaflower tea and sugar
concentrations.
