Abstract

Torbangun leaf (Plectranthus amboinicius L. Spreng) and Katuk leaf (Sauropus androgynous L. Merr.) are plants that are believed to have galactagogues properties but their utilizations are still limited. The main objective of this research was to utilized Torbangun leaf and Katuk leaf in filtrate form to be developed as green grass jelly and finding the best formulation on the nutritional content and organoleptic properties. Three different types of filtrates were used, which were Torbangun filtrate, Katuk filtrate, and combination of Torbangun and Katuk filtrate. The filtrate was added to green grass jelly with three different ratios of 1:1, 2:1, and 1.2 (green grass jelly:filtrate). Physicochemical properties including syneresis, antioxidant activity, total phenolic content, and flavonoid content were done. Also, sensory evaluation such as hedonic test and scoring test were conducted. The result showed addition of lower filtrate amount (2:1) resulted in lower rate of syneresis. While, addition of combination of Torbangun and Katuk filtrate resulted exhibited highest antioxidant activity (1076.91±16.09). Whereas, higher ratio of Torbangun filtrate (2:1) resulted in highest phenolic content (921.99±21.47). Moreover, higher ratio of green grass jelly (2:1) with Torbangun and Katuk filtrate showed highest phenolic content (522.73±6.79). Based on antioxidant activity and organoleptic properties, green grass jelly added with Torbangun and Katuk filtrate with ratio 2:1 was selected as best product as it had IC50 of 1126.35±14.75 µg/ml and highest overall likeness value (4.63±0.67).
