Jeruju leaves are herbal plants belonging to the mangrove group. These leaves have been processed into loloh and instant powder drinks, but their taste and aroma have not yet been widely appreciated, despite jeruju leaves being reported to have potential as functional food. Enhancement of aroma and taste is achieved by adding emprit ginger, which possesses distinctive flavor and aroma characteristics. This research aimed to determine the effect of adding emprit ginger on instant powdered jeruju leaf drink characteristic, identify the right concentration of emprit ginger for the best characteristics, and evaluate its potential as a functional food. The research employed a completely randomized design (CRD) with emprit ginger addition of five levels (0%, 10%, 20%, 30%, and 40%), each replicated 3 times. Analysis of variance (ANOVA) and Duncan's multiple range test were used for analyzed data. The results showed adding emprit ginger significantly affected the yield, moisture content, ash content, total phenolic content, antioxidant activity, ?-glucosidase enzyme inhibition activity, solubility, dissolution time, and sensory attributes including color, aroma, taste, and overall acceptance of the instant powdered jeruju leaf drink.
