Abstract:
This study explores the potential of Libas (Spondias Pinnata) leaves as a sustainable raw material for the production of sinigang powder, a traditional Filipino souring agent. As a response to the increasing demand for natural, preservative-free, and locally-sourced food products, this research aimed to develop a health-conscious alternative to commercial sinigang powders. An experimental research design was used to test varying sun-drying durations of the leaves—three, five, and seven days—to determine the optimal method for preserving the leaves’ flavor, aroma, and nutritional properties. Sensory evaluations were conducted with 30 respondents to assess the appearance, taste, texture, and aroma of the sinigang powder. The findings showed that seven days of sun-drying yielded the most preferred product, receiving the highest ratings across all sensory attributes. Additionally, physicochemical analysis revealed a titratable acidity of 0.1914% and a pH of 4.35, confirming the product’s suitability as a souring agent. The results suggest that Libas sinigang powder can serve as a health-conscious, marketable alternative to conventional seasoning products while promoting local farming and economic growth.
