Abstract

Bitter gourd (Momordica charantia) is a medicinal plant widely cultivated in Indonesia. The aim of this present study was to investigate application of ultrasound assisted extraction (UAE) and vacuum evaporation (VE) to turn the fruit into a concentrate with focus on increasing extract’s total phenolic content (TPC), antioxidant activity (AA) and storage stability. UAE was done under various level of time and temperature with o the best combination found were 5 minutes and 25 C respectively. VE of the extract at o 125 mmHg and water bath temperature set at 65 C showed that concentrate concentration factor (CF) was linearly correlated to its TPC and AA. Stability study of o o the concentrate under different storage temperature (4 C and 25 C) without preservative was done for 14 days. Higher CF enhance shelf life and AA stability in both storage temperature. This study concluded that UAE may reduce the required extraction temperature and time used for yielding higher TPC and AA. Also, VE may concentrate the extract without damaging its TPC and AA. Lastly, VE may provide higher TPC, AA, and lower volume while increasing storage stability of the extract.
