Abstract: This study aims to determine the nature of the toxicity of liquid smoke cinnamon obtained from the purification and concentration of different liquid smoke. This study was carried out experimentally using a factorial experiment in a completely randomized design of 8 (eight) treatment purification with 7 (seven) the concentration of liquid smoke with 3 replicates in order to obtain 168 experimental units. The treatment of liquid smoke purification include purification by distillation temperature of 100 ± 10 ° C; purification by distillation temperature of 140 ± 10 ° C; purification using activated charcoal, purification using activated charcoal and zeolite mixture (50:50), purification by decantation for 1 day, 2 days and decantation decantation 3 days.
