Test liquid smoke toxicity for cocoa skin (Theobroma Cacao- L) with the BSLT method at different pyrolysis temperatures

Cocoa is one of the leading plantation sector commodities in West Sumatra. Cocoa skin waste is still of little use. One of the uses of cocoa pods can be used as raw material for making liquid smoke. The purpose of this study was to determine the toxicity properties of liquid smoke of cocoa pod skin with the BLST method at different pyrolysis temperatures. Testing the toxicity of liquid smoke of cocoa skin using the Brine Shrimp Lethality Test (BSLT) method. The results LC50 number of cocoa shell liquid smoke at pyrolysis temperature (200oC at 10% water content) was 11,858.58 ppm, pyrolysis temperature (200oC at 15% water content) at 13,094.23 ppm, pyrolysis temperature (200oC at 20 water content %) of 3,373.94 ppm, pyrolysis temperature (200oC at 25% water content) of 15,703.52 ppm. The next a pyrolysis temperature of 300oC 10% water content of 11,604,26 ppm, pyrolysis temperature of 300oC 15% water content of 11,673,05 ppm, pyrolysis temperature of 300oC 20% water content of 13,373,94 ppm, pyrolysis temperature of 25% water content of 13,373.94 ppm. Furthermore, at a pyrolysis temperature of 400oC at a level of 10% at 9,213.73 ppm, a pyrolysis temperature at 400oC at a level of 15% at 13,094237 ppm, a pyrolysis temperature at 400oC at a level of 20% at 13,373.94 ppm, a pyrolysis temperature at a level of 25% at 12,493.63 ppm. All the results of the process of making liquid cocoa skin smoke at different pyrolysis temperatures show the results of liquid smoke with toxic properties classified as non-toxic.
