The Effect of Durian Husk and Coconut Shell Combination in the Liquid Smoke Generation: A Review
Proceedings of the International Seminar of Science and Applied Technology (ISSAT 2020)
The husk of durian can be used as a source of cellulose, hemicellulose, lignin, and pectin to generate liquid smoke, and there are several types of researches that have done this. Liquid smokes can be used as natural food preservation because of the presence of antibacterial substance, there are two important compounds i.e., phenol and acetic acid. There are several factors influencing the concentration of an antimicrobial substance in liquid smoke, one of them is the temperature of the
... ture of the pyrolysis, as well as the type of wood used to generate the smoke. The type of wood defines the biomass content of lignin, cellulose, and hemicellulose, and this has been proven through two-way ANOVA analysis to be a significant factor in the concentration of phenol and acetic acid in liquid smoke. Meanwhile, temperature is not a significant factor in the generation of phenol and acetic acid. Durian husk has low lignin and hemicellulose content so coconut shell is added to increase the lignin and hemicellulose in the feed. This study aimed to obtain the best composition of durian husk and coconut shell in the liquid smoke generation based on phenol and acetic acid. Reviewing the literature through systematic review and meta-analysis was chosen as the method to determine the best variation of composition. The variations ratio between durian husk and coconut shell were 5:0; 4:1; 3:2; 2:3; 1:4 and 0:5 with a total mass of 5 kg and with temperature variation of 300 o C and 400 o C. The best variation was DTK6 at 300 o C, pyrolysis of 5 kg coconut shell which produced the highest amount of phenol and acetic acid with the value of 2.502% and 2.572%.
