CHARACTER OF COCONUT SHELL LIQUID SMOKEA research on effect of coconut shell pyrolisis temperature and liquid smoke
distillation on character of resulted liquid smoke has been done. Objective of the research
is to identify effect of coconut shell pyrolisis temperature and liquid smoke distillation on
character of coconut shell liquid smoke distillate. Liquid smoke was obtained with
pyrolisis using pyrolisis reactor on temperature range of 150 to 450oC. Liquid smoke
purification was done by decantation, filtering and distillation at various temperatures:
<100 (D-I), 100-120 (D-II), 121-140 (D-III), 141-160 (D-IV), 161-180 (D-V) and 181-
200 (D-VI). Liquid smoke characteristic was done by determining physical and chemical
characteristic such as density, bias index, pH, acid level and phenol level. The result
indicated that temperature of coconut shell pyrolisis and liquid smoke distillation affect
concentration and liquid smoke characteristic. Highest liquid smoke concentration was
obtained in pyrolisis temperature of 150-200oC (6.07% (v/m)) and the lowest one (0.85%
(v/m) at temperature of 351-4500C. highest tar concentration (1.03% (v/m) was obtained
at 276-350oC, and the lowest (0.20% (v/m)) at 150-200oC. Charcoal concentration was
28.75% (m/m). Characteristic (pH, acid level and phenol level) of liquid smoke before
and after purification process and distillation are various. Highest pH (6.2) was D-I, while
the lowest (4.1) at D-VI. The highest acid level (58.40%) was at D-VI, while the lowest
(1.86%) was at D-I. at D-I liquid smoke does not contain phenol, while the highest
phenol content (3.85%) was in D-VI and the lowest was liquid smoke residue (1.93%)Lombok Johny ZethSetiaji BambangTrisunaryanti WegaWijaya Karna
