Abstract

This study aims to study the characteristics of herbal teabags from belimbing wuluh leaves and gotu kola leaves with the addition of cinnamon powder. This study used a completely randomized design with 5 treatments, namely differences in the addition of cinnamon powder 0%, 1%, 2%, 3% and 4% with 3 replications. The data obtained were analyzed statistically using ANOVA (Analysis Of Variance) and if they were significantly different, then continued with the DNMRT (Duncan's News Multiple Range Test) test at 5% level. The results showed that the level of addition of cinnamon powder had a significant effect on antioxidant activity, total water soluble ingredients, total polyphenols, color, taste, and flavor. Differences in the substitution level of cinnamon powder had no significant effect on water content and pH. The best treatment in this study was treatment E with the addition of 4% cinnamon powder, the organoleptic results obtained were the average value of color preference 3.95 (like), taste 3.65 (like), and flavor 4 (like). The results of chemical analysis on tea products are water content 7.88%, total polyphenols 109.32 mg GAE/g, IC50 value 96.71, total water soluble ingredients 19.66% and in steeped tea pH value is 6.13, and activity antioxidant 36.93%.

Abstract

This study aims to determine the effect of the addition of red dragon fruit juice on the characteristics and organoleptics of belimbing wuluh syrup. The experimental design used in this study was a completely randomized design (CRD) with five treatments and three replications. The treatment carried out in the study was the addition of red dragon fruit juice at concentrations of 0%, 5%, 10, 15%, and 20%. The results showed that the addition of red dragon fruit juice had a significant effect on physical tests (color), chemical tests (pH, total sugar content, vitamin C, total acid, antioxidant activity, betacyanin levels), and organoleptic tests (color and taste). and did not have a significant effect on the organoleptic test (aroma). The best treatment based on physical, chemical, microbiological, and organoleptic properties was the addition of red dragon fruit juice with a concentration of 20%, with color test results of 17.87°H, pH (3.67), total sugar content (73.99%), vitamin C (16.19 mg/100g), total acid (1.11%), antioxidant activity (44.65%), betacyanin content (1.63%), total plate number (2.46 102 CFU/g), and organoleptic analysis of color 4.20 (like), aroma 3.55 (like), and taste 3.85 (like).
