Analysis on the Quality of Kaffir lime Oil Based on Different Distillation Temperature Using Automated Steam Distillation Process.
This section is to investigate on how steam temperature influenced the quality of Kaffir lime peels oil based on different controlled temperature conditions. The concentration amount of compounds in Kaffir lime oil was identified using Gas Chromatography (GC) and Gas Chromatography – Mass Spectrometry (GC-MS) for each experimental sample. The chromatograms executed the peak ratio and each of peaks corresponds to particular compound at their respective retention time. Table 3 shows list of major volatile compounds derived in this experiment starting with á-Thujene occurred at lowest retention index 924 until Citronellol at 1223 of retention index. In the case of uncontrolled temperature, some important compounds were not found. The discrepancy may due to incomplete extraction process or the oil experienced thermal degradation that consequently losing some significant volatile compounds such as linalool and terpinen-4-ol.
