Optimization of Liquid Smoke from Shorea pachyphylla using Response Surface Methodology and its Characterization

The present study aims to optimize the processing variables producing liquid smoke from mabang wood (Shorea pachyphylla) by using Response Surface Methodology (RSM). In this investigation, a design of experiment with different combinations pyrolysis temperature and time on yield was applied. response optimal yield, temperature, predicted mathematical model. operating conditions for process yielding 31.31% were identified at 440◦C 124 minutes. effect more significant than (p<0.05). samples evaluated GC-MS. main chemical compound 1,2-ethanediol (19.26%), fluoromethane (6.69%), formic acid (4.96%), 2-propanone (4.17%), acetic (18.64%), acetol (4.80%), furfural (9.94%), 2,4-hexadecanoic (3.45%), guaiacol (2.93%).
