Nutritional Composition, Antioxidant Potential and Food Applications of Melothria scabra (Cucamelon): A Review and Experimental Study

Abstract

Melothria scabra (commonly known as cucamelon or mouse melon) is a relatively underutilized fruit with unique sensory and nutritional characteristics. Despite its visual appeal and exotic flavor profile, research on its health-promoting potential and food applications remains limited. This paper reviews the existing literature and presents experimental findings on the nutritional composition, antioxidant capacity and possible uses of Melothria scabra in nutraceutical and food products. Using standard AOAC methods, protein content was found to be 1.82 g/100g and carbohydrate content 9.4 g/100g. Antioxidant analysis using the DPPH assay showed a high free radical scavenging activity of 78.5%. Several product prototypes, including jam, smoothies and health bars, were developed and evaluated, with consumer acceptability ratings ranging from 7 to 9 out of 10. These findings highlight the potential of Melothria scabra as a novel functional ingredient in food and healthcare industries. Further studies are needed to characterize its bioactive compounds, assess safety and optimize formulations.
