Abstract

Chemical characteristics of coffee are depended on types of coffee. Different types of coffee have the unique characteristic. Chemical components have significant effects on taste and aroma of brewing. Those characteristics are the result of volatile and nonvolatile components during roasting then affecting taste. Kopi Luwak has distinct chemical and taste from regular coffee. On previous research, Marcone (2004b) and Mahendratta et al. (2011) explained that quality improvement on Kopi Luwak is result of lower protein content and higher fat content compared to regular coffee. Lower protein content reduces bitter taste while higher fat content can increase body or feeling heavy. The aim of this research was to obtain information about chemical compound of Kopi Luwak and regular Arabica coffee. From this study, it can be analyzed that protein content of regular green coffee beans was 9.48%, and regular roasted bean was 11.3% while protein content of Kopi Luwak green bean was 8.8%, and its roasted bean was 10.12%.

Abstract

Patchouli oil is one of Indonesia's important essential oils as an export commodity. Δ-Guaiene is one of the terpenes in the oil, which is shown to have antimicrobial activity against some fungi and bacteria. Thus, the production of δ-guaiene needs to be optimized. This study aims to determine the appropriate pressure and reflux ratio for the fractional distillation process that isolates the highest δ-guaiene content. The experiment used the response surface method. The pressure of the fractional distillation process and reflux ratio were: 1;10; 20 mmHg; and 5:1; 20:1; 35:1. The temperature ranged from 270‒272°C. Various pressure did not give different yields, except at a pressure of 1 mmHg that resulted in 4% yield and δ-guaiene content of 20.46%; both conditions were optimum. The δ-guaiene was characterized for the density, refractive index, distillate formation rate, distillation time, residual mass, and electrical energy requirements, which were 0.9519, 1.5027, 4 mL/min, 1 minute, 6.31 g, and 6.0477 kW/h, respectively. The lower the reflux ratio, the faster the distillation process; the faster the processing time, the lower the energy requirement; and the higher the ratio of reflux, the purer the percentage of the δ-guaiene. The optimum process was reached as the reflux ratio was lower, where the yield and δ-guaiene content were the highest, and the processing time was faster.
