ABSTRACT
Biomass is a fuel that can be used directly or processed first into solid, liquid or gas fuel through a certain process. Liquid smoke produced from the torrefaction process is a condensation liquid that comes from heating biomass without oxygen. The clarification of liquid smoke used as a food preservative must be carried out through a distillation and adsorption process first. The objectives to be achieved in this study are to synthesize liquid smoke and activated carbon from oil palm fronds, to study the effect of the amount of adsorbent and adsorption time on the clarification of liquid smoke, and to compare the characteristics of liquid smoke with the quality standards of liquid smoke according to SNI. The raw material used in this study was 3 kg of previously dried oil palm fronds. The manufacture of this liquid smoke was carried out in several stages, namely, the torrefaction stage, the distillation (purification) stage, and the adsorption stage. The liquid smoke obtained was calculated for its yield and tested for its characteristics. From 1300 g of oil palm frond raw material, a yield of 43.33% was obtained. From the results of the analysis of liquid smoke that has gone through a purification process by varying the amount of adsorbent 1; 2 and 3 g, and the time to purification 40; 60 and 80 minutes. The pH value of the liquid smoke was 2.40-2.60, the density was 1.014 - 1.024 g / mL and the total titrated acid was 3.30 - 4.18%. On the color and odor of liquid smoke, organoleptic tests were carried out with 30 panelists, the results given by the panelists showed that liquid smoke tended to have a yellow color and a slight odor.Based on the results of this study, liquid smoke has met the quality standards of liquid smoke based on the Indonesian National Standard (SNI 8985-2021).
Keywords: liquid smoke, torrefaction, palm fronds, SNI
