Abstract
Recycling garbage with the pyrolysis technique to make liquid smoke is one effort to utilize biomass waste. Because it includes acetic acid and phenol, which aid in food preservation, liquid smoke can be used on foods. The goal of this research was to look into the usage of zeolite catalysts in the production of liquid smoke from various types of biomass via catalytic pyrolysis. Coconut shells, corn cobs, and rice husks are used as biomass. The investigation began with the activation of the zeolite catalyst, with the goal of cleansing the catalyst of impurities and boosting its activity by opening the pores. The catalytic pyrolysis process was then carried out at 350°C for 2 hours while adjusting the quantity of catalyst addition (4%, 5%, and 6%). Catalytic pyrolysis liquid smoke is collected and evaluated. As a preservative, studied liquid smoke is applied to skipjack tuna. Based on the quality of commercial liquid smoke, the results showed that coconut shell liquid smoke with a percentage of 6% zeolite added was the most optimal liquid smoke. 6.5% yield, yellowish brown hue, slightly pungent aroma, pH value 2, density 1.132 g/ml, acid content 24%, and viscosity 1.3090 cP were the features of 6% zeolite coconut shell liquid smoke.
