Abstract

The objective of this research was to analyze the physical, Chemical and sensory characteristics of retrograded rice with six cycles of autoclaving-cooling treatments. This research was conducted in the Chemical Laboratory of Agricultural, Department of Agricultural Technology, Agricultural Faculty, Sriwijaya University Indralaya, from September 2011 to January 2012. This research used a Non Factorial Completely Randomized Design with six treatments and three replications for each treatment. The treatment was the amount of autoclaving-cooling process which was assumed as a cycle. One cycle consisted of autoclaving at 121°C for 15 minutes, cooling at 4°C for 24 hours. The observed parameters were physical (texture and color), Chemical (water content, total sugar and glycemic index) and sensory characteristics by hedonic test (color, taste and texture). The results showed that autoclaving-cooling cycles had significant effect the texture, total sugar and sensory characteristics (color and flavor). retrograded rice with six cycles of autoclaving and cooling (A6) had the lowest total sugar (0.13°Brix) and low index glycemic (52.46 %). The treatment of A4 (4 cycles) was the most preferred retrograded rice with the texture of 29.33 gf, 70.40% on The lightness, 4.17% chroma, 103° hue, 2.56% water content, and the preference scores for its color, taste and texture of 2.80, 2.36 and 2.20, respectively
