| dc.description.abstract | Liquid smoke result from condensation of combustible materials that contain lignin,
cellulose, and hemicelluloses. Liquid smoke is categorized by its level of purity and
the active compound such as acetic acid and phenol. The purpose of this study was to
characterize the liquid smoke by adsorption and desorption method including total
acid content, total phenol content, pH, and density. Different properties compound
in liquid smoke obtained with variation of mass and type of zeolite. As much as 10
gram natural zeolite on adsorption fraction showed the highest acid and total phenol
content, which were 9% and 13,7% respectively. The other hand of desorption
fraction method with the highest acid and total phenol content was obtained by using
activated natural zeolite 90 grams were 6,3% and 9,4% respectively. Activation
zeolite as much as 90 grams showed the highest adsorption mass of liquid smoke
thats 19,3 gram. Variation of type and mass of adsorbent did not give a significant
influence to the value of density and pH of liquid smoke where the value of each
ranged from 1,001-1,107 and 2,5-3 respectively. The results showed that the
characteristic of adsorption fraction and desorption fraction have passed the standard
quality of Japanese liquid smoke | en_US |
