Gummy candy is a soft candy made from water or fruit juice, a mixture of sugar, and gelling ingredients. Aloe vera juice is one of the ingredients that can be made into gummy candy. The use of rosella flowers as a natural coloring is expected to increase the color attractiveness, vitamin C and antioxidant activity of gummy candy. This study aims to determine the effect of the comparison of aloe vera and rosella flower on the characteristics of gummy candy and to obtain the right comparison to produce gummy candy with the best characteristics.
