Abstract

The purpose of this research was to analyze the physical, chemical, and sensory characteristics of pumpkin fruit leather with the addition of gum arabic and carrageenan. The research was conducted in Agricultural Chemistry Laboratory and Sensory Evaluation Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, from February to May 2018. This research was conducted by using Factorial Group Randomized Design (RAKF) with two factors and treatment was repeated three times. The first factor was addition of gum arabic and carrageenan and the second factor was the addition of consentration gum arabic and carrageenan (0.1% ; 0.3% ; 0.5%). The observed parameters were physical characteristics (texture), chemical characteristics (water content, ash content, water activity, and karotenoid total) and organoleptic test (texture, colour and taste). The results showed that the addition of gum arabic and carrageenan had significant effect on water content and texture), while the addition of consentration had significant effect on water content, and texture. The treatment of A2B1 (carrageenan) was the best treatment with the highest level of acceptance based on organoleptic test. The characteristics of A2B1 were 62.20 gf texture, 13.60% water content, 1.74% ash content, 0.68 water activity, 68.09 mg/g carotenoid total and hedonic scores for color, texture, and taste were 3.04 ; 2.85 ; 2.85 respectively.
