Abstract
ABSTRACT The aim of this study was to determine the ratio of water with fruits appropriate and to determine the appropriate concentration of stabilizer and to investigate the interaction between the ratio of the fruit with water and the concentration of the stabilizer on the characteristics of the juice of snakefruits Bongkok. The preliminary study is to determine the appropriate addition of sucrose concentration and stabilizer right with organoleptic response. Primary research carried out by using a randomized block design (RBD) consisting of two factors: factor A (comparison fruit with water), which consists of 5 levels ie a1 (1: 1), a2 (1: 2), a3 (1: 3) , a4 (1: 4), a5 (1: 5) and factor B (concentration of stabilizer), which consists of three levels ie b1 (0.5%), b2 (0.75%), b3 (1%). The responses are used in the main study chemical response that consists of antioxidant activity, moisture content and TSS (Total Soluble Solid), physical responses that the viscosity and organoleptic responses that include taste, aroma and appearance. Based on preliminary research results, obtained the best sucrose concentrations of 10% and the best type of stabilizer that is dextrin (a3b2 treatment with sample code 896). Based on the results of primary research, it is known that the interaction comparisons fruit with water and concentration of stabilizer significant effect on antioxidant activity, moisture content, TSS and viscosity. The best treatment is fruit juice and water with a ratio of 1: 1 with a stabilizer concentration of 0.5% (a1b1 treatment with sample code 392) which has a value of IC50 91.9555 mg / mL, the water content of 69.725%, amounting to 26.185% TSS and viscosity of 2.8885 kg / m.s.
