The purpose of this research was to study the solubility of chitosan in the liquid smoke as a preliminary study for the application of liquid-chitosan combination as a bioimmunizer and growth booster in plants and as a preservative in fish processing. This research focused on redistillation and characterization of the liquid smoke from ulin wood ( Eusideroxylon zwageri Teijsm. & Binn.) and its ability as a chitosan solvent. The purpose was to obtain the scientific data on the yield redistillation, characterization of the liquid smoke (pH, total acid, total phenol, and composition), and its ability as a chitosan solvent. This liquid smoke was the side product of ulin wood charcoal in South Kalimantan. The results showed that the yield of liquid smoke from redistillation was 76.14% and the characteristics were containing 2.21 pH, 3.38% g/mL of total acid, 3.05 g/L of total phenol, and other chemical compositions such as carboxylic acid (73.08%), alcohol (14.73%), carbonyl (9.43%), phenolic (1.56%), and ether (1.21%). This research also uncovered that the solubility of chitosan in the liquid smoke increased along with the higher value of the liquid smoke concentration, and the liquid smoke concentration of 5% was able to dissolve more than 50 g/L of the chitosan.
