Abstract

Ginger (Zingiber officinale Rosc.) can be optimized as a raw material for making kombucha because it contains many active compounds that are beneficial for health. Making kombucha is done with the help of Scoby which requires sugar media as a growth substrate. This study aims to determine the optimal conditions for making ginger kombucha. This study uses the surface response method with central composite design (CCD), the observed variables are sugar concentration and ginger concentration, with a total acid response. The results of the study on the optimum proportion have a desirability value of 0.845 at a sugar concentration of 10% and a ginger concentration of 75% with a total acid response of 0.582±0.012%. From the results of the optimum proportion, characterization was also carried out on antioxidant activity of 182.71 mg TE, vitamin C content of 0.02%, total sugar 0.76%, color, Total Dissolved Solids, pH, and organoleptic tests.

Abstract

This study aimed to determine the effect of the proportion of tempe gembus and oyster mushroom on the physicochemical characteristics of a plant-based flavor enhancer produced by foam-mat drying. The study employed a single-factor Completely Randomized Design (CRD) with seven treatments: T1 (100:0), T2 (70:30), T3 (60:40), T4 (50:50), T5 (40:60), T6 (30:70), and T7 (0:100). The results showed that the proportion of tempe gembus and oyster mushroom significantly affected the water solubility index, color profile, glutamate content, and ash content of the plant-based flavor enhancer. Based on the effectiveness index analysis, the best treatment was T1 (100% tempe gembus), with the following characteristics: glutamate content of 19.47 mg/g, moisture content of 7.39%, ash content of 0.95%, water solubility index of 0.0933 g/mL, yield of 17.66%, and color profile (L: 79.02; a*: 3.45; and b*: 16.45).
