In this study, essential oil of Sweet lime peel, which is a waste in juice industry, was extracted using microwave assisted hydrodistillation and characterization of essential oil has been performed using GC-MS. Extraction efficiencies of extraction process was investigated by varying three factors, time of extraction, microwave power, particle size and dryness period. The results showed that all the concerned factors have a positive effect on the yield. Oil yield is proportional to extraction time and microwave power. Higher yield can be obtained with smaller particle size and dried sample. The essential oil of sweet lime peel is mainly comprised of d-limonene (on average 78.30%). oil is mixture bioactive isomers. microwave assisted hydrodistillation is successfully applied in sweet lime peel processing.
