PENGARUH KONSENTRASI KARAGENAN DAN GELATIN TERHADAP SIFAT FISIK, KIMIA, DAN ORGANOLEPTIK PERMEN JELLY SERAI (Cymbopogon citratus)

- The purpose of this research was to analyze the effect of carrageenan and gelatin concentration on the physical, chemical and organoleptic characteristic of lemongrass (Cymbopogon citratus) jelly candy. The research was conducted in Agricultural Chemistry Laboratory, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, from February 2018 until September 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 type of gel forming material (carrageenan and gelatin) and the second factor was the concentration of gelling material (5% ; 7.5% ; 10% ; 12.5%). The observed parameters were physical characteristics (texture and colour), chemical characteristics (water content, ash content, pH, redusing sugar and antioxidant activity) and organoleptic test (colour, taste, flavor, and texture). The results showed that the type of gel forming material had significant effect on texture, colour (lightness, redness, and yellowness) and redusing sugar, while factor of gel-forming concentration of 10% can incrase water content, ash content, pH, and reducing sugar, but decreases of texture, and IC50. The interaction between them have a significant effect of reducing sugar and texture, based in hedonic test which includes colour, taste, flavor and texture, the most favored sample by panelists on A2B4 treatment (gelatin with 12,5% concentration).
