Abstract

The purpose of this research was to determine the effect of addition rosella (Hibiscuss sabrarifa L.) extract and fermentation time on the characteristics of physical, chemical and sensory of bika ambon. The research was conducted in Agricultural Chemistry Laboratory and Sensory Evaluation Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, from November 2017 until July 2018. This research was conducted by using Factorial Completely Randomized Design (RALF) with two factors and treatment was repeated three times. The first factor was addition of rosella extract (50% ; 75% ; 100%) and the second factor was the fermentation time (1 hour ; 1.5 hours ; 2 hours). The observed parameters were chemical characteristics (water content, ash content and antioxidant activity) physical characteristics (texture and colour) and organoleptic test (colour, texture, taste and odour). The results showed that the concentration of rosella extract had significant effect on water content, ash content, antioxidant activity, colour (L*, a* and b*) and texture, while the fermentation time had significant effect on water content, antioxidant activity, colour (L*, a* and b*) and texture. The treatment of A2B3 (concentration of rosella extract 75% and fermentation time 2 hours) was the best treatment with the highest level of acceptance based on organoleptic test. The characteristics of A2B3 were 36.69% water content, 0.84% ash content, and 460.52 mg/mL IC50 weak antioxidant activity, 44.2% L*, 12.9 a*, 6.8 b*, 27.95 gf texture and hedonic scores for colour, texture, taste and odour were 3.0 ; 3.08 ; 3.24 ; 2.92 respectively means like.
