EFFECT OF SOLVENT AND EXTRACTION TIME VARIATION ON THE COFFEE OIL EXTRACTION RESULTS

The traditional coffee with the greatest taste is called arabica. One of ingredients made from beans and used for air freshener oil. Soxhlet extraction method, a separation technique that often to separate one or more compounds solid liquid by adding solvent, processes making This research has been done before, but comparison different types solvents inclusion differences in time not done. purpose this understand how difference solvent affect yield, density, acid number produced. Extraction hexane ethanol distillation 120 minutes technique. times were 90, 120, 150 180 minutes. In study, largest was produced within 25.75%, while highest percent yield oil obtained 17.3%. maximum specific gravity 0.94 gr/ml, 0.91 g/mL. Coffee an value between 3.2 7 mg KOH/g, 4.6 11.2 KOH/g.
