Abstract
Gotu kola leaves have a bitter taste so sweeteners need to be added so that
the bitter taste in the gotu kola leaves can be completely covered in addition
to powdered honey as a substitute for aspartame. So therefore this research
was conducted to determine the effect of adding honey powder on the
quality of the gotu kola leaf effervescent drink physically, chemically and
sensoryly. There is only one variable, namely powdered honey with different
concentrations (10%, 15%, 20%, 25%, 30%). The variables measured in
this study were physical tests (dissolving time), chemical tests (moisture
content, ash content, pH value, antioxidant activity), sensory tests (color,
aroma, luster, taste). The data analysis technique used analysis of variance
(ANOVA) followed by Duncan's test with = 0.05 which shows a significant
difference. The results showed that the interaction between gotu kola leaf
effervescent drink and honey powder had a significant effect at = 0.05 on
the dissolving time of each concentration and hedonic aroma. While the
concentration of powdered honey had no significant effect at = 0.05 on
water content, ash content, pH, antioxidant activity, hedonic quality tests
(color, luster, taste) and hedonic quality. Powdered honey with a
concentration of 25% produces the best quality effervescent drink. This
treatment has a solubility value of 21.84s, water content is 6.415%. ash
content 0.2179%, antioxidant activity 0.7059, pH value 5.6%.
