Study of liquid smoke toxicity cocoa shell with different purification methods

Abstract

Cocoa shell is an underutilized agricultural trash. Cocoa shells can be used to make liquid smoke and cocoa charcoal as basic materials. The charcoal made from cocoa pod husks can be used as a dye adsorbent. The study will look at the effects of different purification and filtering procedures on the toxicity of liquid smoke from cocoa husks in order to determine which purification process is best for making liquid smoke from cocoa husks that is not harmful. The results demonstrated that several procedures for purifying and filtering liquid smoke from cocoa peels were non-toxic. Cocoa shell is an underutilized waste from plantations. Cocoa shells can be used as raw materials in the manufacture of liquid smoke and cocoa charcoal. The burning of cocoa pod husks charcoal can be used as a dye adsorbent. The research intends to observe the different purification and filtering methods on the liquid smoke toxicity from cocoa husks to find out which purification method is more appropriate for liquid smoke from cocoa husks so that it is not toxic. The results showed that the purification and filtering of liquid smoke from cocoa peels using various methods were non-toxic. The best approach with the highest LD50 value is zeolite purification, which has an LD50 value of 3019.95 ppm. The activated charcoal technique, activated charcoal + zeolite method, and distillation method were then used, with LD50 values of 2,951.21 ppm, 2,398.83 ppm, and 1,412.54 ppm, respectively.
