Utilization of Snake Fruit (Salacca Zalacca) for Arak Using Distillers Active Dry Yeast With Different Sugar Concentration: Physicochemical Properties and Sensorial Analysis
Arak, a traditional Indonesian spirit typically produced from rice or sugarcane, is made by fermenting
rice or fruit juice followed by distillation. This research explores using snake fruit (Salacca Zalacca var
Pondoh) as an innovative raw material for Arak production, offering a novel flavor profile and creating a
niche market. Snake fruit, containing fermentable sugars, presents a cost-effective alternative for Arak
production in Indonesia, potentially reducing post-harvest losses. While commonly consumed fresh,
utilizing snake fruit for Arak production may create a new market for this fruit, increasing its demand.
Rising demand could encourage improvements in supply chain management and significantly increase
the value of snake fruit compared to selling it fresh. This study evaluated the impact of different sugar
concentrations on fermentation viability, physicochemical properties, and sensory profiles, including pH,
Brix, alcohol content, specific gravity, viscosity, and internal descriptive sensory characteristics. Results
indicate that lower sugar concentrations (0%, 10%, and 20%) facilitated viable fermentation or were able
to ferment with significant decreases in specific gravity and Brix values and higher alcohol content.
Conversely, a 30% sugar concentration failed to ferment. Variations in sugar concentration significantly
affected physicochemical properties, including pH, viscosity, and alcohol content. pH values decreased
slightly after fermentation due to organic acid production by yeast but increased after distillation.
Viscosity increased with higher sugar concentrations, correlating with residual sugar levels. Sensory
analysis showed minor variations, with the 10% sugar concentration yielding the most balanced profile.
These findings emphasize snake fruit's potential as a viable alternative for Arak production, enhancing
marketability and production efficiency.
