Abstract

Sugarcane bagasse waste is an alternative resource to be a pyrolyzed liquid smoke and has potential antibacterial activity. This study presents liquid smoke produced from sugarcane bagasse, determine the effect of active natural zeolite on the production of liquid smoke, and determine the antibacterial activity of liquid smoke. Liquid smoke was synthesized by pyrolysis of the sugarcane bagasse catalyzed by active natural zeolite (0%, 1%, 2% and 3% w/w). Liquid smoke was identified for its physicochemical properties including density, refractive index, viscosity, and acid number and characterized by FTIR and GC-MS. The results showed that active natural zeolite contained Heulandite and clinoptilolite phases. The addition of active natural zeolite catalyst increased the yield. The optimum catalyst usage was 2% w/w catalyst with 47.05% yield. The main compound component contained in the liquid smoke was ethanoic acid. By antibacterial activity, the zone of inhibition produced in the antibacterial test of gram-positive S. aureus and gram-negative E. coli on liquid smoke pyrolysis without catalyst and catalyzed by active natural zeolite were very strong.
