| dc.description.abstract | The present study was undertaken to find the kinetics of sweet basil oil extraction using steam and hydro distillation techniques, to access the quality of extracted oil and to optimize the process parameters for oil extraction. Sweet basil was procured from farms of Fieldfresh Foods Pvt. Ltd., VPO Ladhowal, Distt Ludhiana. The oil was extracted from fresh sweet basil leaves, shade dried sweet basil leaves and sun dried sweet basil leaves with moisture content 85.29%, 17.33% and 12.75% respectively. For extraction of oil from sweet Basil leaves at different moisture contents hydro distillation and steam distillation methods took 3-6 and 0.75- 1 hrs respectively. In case of hydro distillation method there is no oil recovery for each sample during first one hour and it started during second hour whereas in case of steam distillation method oil recovery started within 15 minutes. Maximum yield of 0.27% at 17.33% moisture content and minimum oil yield of 0.23% at 12.75% moisture content was observed in hydro distillation whereas in steam distillation method maximum yield of 0.62% at 85.29% moisture content and minimum yield of 0.16% at 12.75% moisture content was observed. The oil obtained from distillation methods was light yellowish to pale yellowish in color with very little greenish ting. Saponification value, acid value, specific gravity and refractive index were found to be 8.00, 1.90, 0.92 and 1.460 respectively. Sweet basil oil recovered was found to be insoluble in water. Steam distillation method was found to be the best method for oil extraction with maximum oil recovery and minimum time of extraction. | en_US |
