PEROLEHAN DAN IDENTIFIKASI ASAP CAIR DARI BIOMASSA KULIT DURIAN DENGAN MENGGUNAKAN DESTILASI BERTINGKAT

Abstract

Abstract 

Durian skin can be utilized through the pyrolysis process to produce liquid smoke which can be used as a preservative because it has antibacterial and antioxidant properties. Liquid smoke is one of the latest methods for preservation of food obtained through the pyrolysis process of materials containing cellulose 60%, hemicellulose 5%, and lignin 5%, and then followed by the process of condensation in the cooling condenser.The purpose of this study was to determine the acquisition of liquid smoke from the pyrolysis process of carbonisators and determine  the quality and composition of liquid smoke using vacuum stratified distillation. The method used is the experimental method with the pyrolysis process reaching 2 hours. The results of combustion produce liquid smoke with a yield of 16.5%, a pH value of 2 with a specific gravity of 1.008 g / cm3. Based on the characteristics of the compound components using GCMS liquid pyrolysis results detected 36 compounds with the highest levels of Benzenetriol compound 24.91%. Benzenetriol is a compound that is carcinogenic so that liquid smoke does not yet qualify as a food preservative but can be used as a wood preservative.
