Abstract

The quality of green coffee is the most important factor that can effect the result of powdered coffee and roasted coffee. A good quality of green coffee would produce high tasted poured coffee. Besides that, roasting process could also effect the quality of roasted coffee. The research was conducted from November 2007 to June 2008 at Sultan Mansyur Street No. 353 Palembang and in Chemical Laboratory of Agricultural Faculty of Sriwijaya University, Indralaya. This research conducted to analyze roasted coffee produced by various quality of green coffee (Grade I, Grade II and Grade III) with the roasting time was 90 minutes, 105 minutes and 120 minutes. The roasting tool used in this research is closed cylinder type. The method used in this research was randomized block design that arranged by factors and each treatment combination was replicated three times. Parameters observed in this research included yield, bulk density, color, moisture content, caffeine content, ash content, and taste of the roasted coffee. The result of this research showed that the quality of green coffee and the roasting time has a significant factor that effected the final result quality of roasted coffee. Each sample (green coffee) produced average yield 82,67% and average bulk density 0,432 g/mL. The color of roasted coffee produced was various, from Yellow (Y) to Yellow Red (YR). Average moisture content of roasted coffee was 1,73%, average caffeine content was 1,3% and average ash content was 4,8474%. The best quality of roasted coffee was Grade I with the roasting time of 120 minutes.
