<![CDATA[Pyrolysis process is the thermal decomposition of biomass in the absence of oxygen. Pyrolysis process coconut plantation to be able to transform waste materials that have a sale value, with good conversion.
Results of the pyrolysis process in the form of bio-charcoal, tar and liquid smoke grade 3. Liquid smoke consists of grade 3, grade 2, and grade 1 , the classification is based on the amount of liquid smoke berbahanya compounds in liquid smoke, thereby affecting the function of the liquid smoke. 3 grade liquid smoke is smoke liquid pyrolysis results that have not undergone a process of purification . Liquid smoke grade 3 is not used as a food preservative , but is used in rubber processing , deodorizing , and
wood preservatives to resist termites . Grade 2 liquid smoke to food preservatives instead of formalin with taste of smoke (smoked meat or smoked fish ) . Whereas grade 1 liquid smoke is used as food preservatives such as meatballs , noodles , tofu , spices and barbeque . Compounds responsible for the preservation process is phenol . Presence of phenol with high boiling point in a smoke is high, so antibacterial substances can prevent bacterial spoilage .
Pyrolysis process begins with sample preparation yaitutempurung coconut , corn cobs and bamboo, then enumeration , drying , and weighing . Then do the pyrolysis process padatemperatur 300 oC . The results of which form the smoke cairgrade pirolis 3 in the analysis by using GC - MS in Organic
Chemistry Laboratory , State University of Brawijaya generate the content of phenolic compounds , carbonyl compounds , acidic compounds , and compounds benzo (a) pirena . From the results of the analysis showed that the amount of phenolic compounds and acetic acid compounds multiply comparable to the temperature rise . Of the three samples used in this study were obtained grade 3 samples of liquid smoke coconut shell , corn cob and bamboo has better quality than the other samples , ie : at a temperature of 300 C , producing phenol compound content of the most highest with corn cobs concentration of 6.73 % at a retention time of 4,502 minutes and compounds acetic Acid is the most supreme of corn cob with a concentration of 84.45 % at a retention time of 2.240 minutes .
Keywords : slow pyrolysis , liquid smoke , phenol, and acetic acid.]]>
