Abstract
This study aims to produce and analyze the quality of purified liquid smoke through the adsorption process with activated carbon and distillation. In this study, liquid smoke was produced from the pyrolysis of oil palm fronds with operating conditions of temperatures of 400°C, 500°C, and 600°C for 40 minutes, 90 minutes, and 120 minutes. Liquid smoke was adsorbed using activated carbon and distilled at 150°C for 45 minutes. The characteristics of liquid smoke were analyzed using GC-MS instrument. The parameters observed were phenolic, acids, and carbonyl compounds. The results showed that acid compounds were the most dominant component in liquid smoke obtained. After purification, the color of liquid smoke turned bright yellow and the pungent smell of smoke from liquid smoke decreased.
