Abstract

The objective of this research was to determine the effect of sugar concentration and storage time on the physical, Chemical and organoleptical characteristics of dodol tapai cassava. This research was conducted at Agricultural product Chemistry and Sensory Laboratoriums, Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University, Indralaya, ffom July up to November 2012. The experiment was conducted on Factorial Completely Randomized Design with two treatments and three replications. The treatment was consisted of three levels of sugar concentrations (5, 10, and 15%) and four levcls of storage times (0, 7, 14, and 28 days). The experiment parameters were include physical analysis in form of texture, color (lightness, chroma, and hue), and browning index, whereas Chemical analysis was consisted of moisture content, ash content, water activity (aw), and reducing sugar, as well as sensory analysis (flavor, color, texture, and taste). The results showed that sugar concentration had significant effect on texture, moisture content, ash content, and reducing sugar. Storage time had significant effect on texture, chroma, hue, browning index, moisture content, ash content, water activity, and reducing sugar. Interaction of sugar concentration and storage time had significant effect on texture and hue. The best treatment based on organoleptic observation was A3B1 (sugar concentration of 15% with storage time of zero days) having texture, chroma, hue, moisture content, water activity (aw), ash content, browning index, and reducing sugar values of 241.20 gf, 24.33%, 83.40°, 10.98%, 0.8, 5.09%, 0.82, and 15.91 mg/g respectively.
