Variasi Ekstrak Bunga Telang (Clitoria Ternatea L.) Terhadap Mutu Kimia Water Kefir
ABSTRACT
Water kefir is probiotic drinks that are fermented from crystal algae grains with water, fruit juice or ingredients containing sugar. Foodstuffs that have potential to be developed as an ingredient for food product processing are butterfly pea. The purpose of this research was to get the best concentration of butterfly pea extract in the manufacture of water kefir drinks. This study was conducted experimentally using a completely randomised design with four treatments and four replications. The treatments consisted of P1 (concentration butterfly pea 0.5%), P2 (concentration butterfly pea 1.0%), P3 (concentration butterfly pea 1.5%) and P4 (concentration butterfly pea 2.0%). Data were analysed statistically using analysis of variance (ANOVA), if Fcount ≥ Ftable then, continue with Duncan’s multiple range test (DMRT) at the 5% level. The result showed that the variation of butterfly pea extract was not significantly affected in the degree of acidity (pH), total acid titrated, total alcohol, and descriptive assessment of aroma and taste as well as hedonic sensory assessment. Based on this research, the best treatment obtained was P3 (concentration butterfly pea 1.5%) with degree of acidity (pH) of 3.60, total lactic acid 0.41%, total alcohol 0.48%, antioxidant activity 2.07 ppm, and description of deep purple colour, slightly sour smell, sour and sweet teste, and overall assessment was favoured by the panellists.
