Abstract

Wedang cemue is a traditional drink originating from the Ngawi area, East Java. The existence of wedang cemue is getting eliminated due to the presence of instant drink that we ready to serve and more practical. To preserve the existence of wedang cemue, an innovation is needed that can promote its existence, which is made cemue into to instant. The purpose of this study was to determine the preference of instant cemue, as well as to determine of antioxidant activity. The product preference test (taste, color and aroma) used hedonic scale. The preference test involved 25 panelist. A part from the hedonic test, antioxidant activity test were also carried out using the DPPH test. This study used a Completely Randomized Design with 1 factor that is the variation of formulations (4 formulations). Each formulation was repeated 3 times. The data obtained werw analyzed using ANOVA and further testing with DMRT. The results of cemue instant showed that the formulation I obtained higher acceptability on color (3,84), aroma (3,68) and taste (3,88). The antioxidant activity of formulation I showed the highest result (71,507).

Abstract

This study aims to determine the optimal pectinase enzyme concentration and hydrolysis duration for the most preferred physical, chemical, and organoleptic characteristics of kweni mango syrup. The research was conducted from October 2024 to August 2025 at the Integrated Laboratory and Basic Science Laboratory of the Agricultural Institute (INTAN) Yogyakarta using a Completely Randomized Design (CRD) with a factorial pattern consisting of two factors and two replications. The first factor was the pectinase enzyme concentration (0%, 0.25%, 0.50%, and 0.75%), and the second factor was the hydrolysis duration (0, 30, and 60 minutes). Observation parameters included yield, vitamin C, viscosity, pH, total soluble solids, and organoleptic attributes. Data were analyzed using ANOVA at a 5% significance level followed by Duncan’s Multiple Range Test (DMRT). The results showed significant effects of both pectinase enzyme concentration and hydrolysis duration on yield, viscosity, total soluble solids, and organoleptic characteristics (color, taste, aroma, and overall acceptability), while no significant effects were observed on vitamin C content and pH. The best formulation was obtained using 0.50% pectinase enzyme concentration with a hydrolysis duration of 30 minutes.
