Test liquid smoke toxicity for cocoa skin [Theobroma Cacao L.] with the BSLT method at different pyrolysis temperatures

Abstract

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 (200°C at 10% water content) was 11,858.58 ppm, pyrolysis temperature (200°C at 15% water content) at 13,094.23 ppm, pyrolysis temperature (200°C at 20 water content %) of 13,373.94 ppm, pyrolysis temperature (200°C at 25% water content) of 15,703.52 ppm. The next a pyrolysis temperature of 300°C 10% water content of 11,604,26 ppm, pyrolysis temperature of 300°C 15% water content of 11,673,05 ppm, pyrolysis temperature of 300°C 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 400°C at a level of 10% at 9,213.73 ppm, a pyrolysis temperature at 400°C at a level of 15% at 13,094237 ppm, a pyrolysis temperature at 400°C 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.
