The Study on Extraction Technology of Essential Oil from Tribute Citru

Abstract

The essential oil from Tribute Citru peel was extracted by steam distillation. The extraction method was studied by single factor test and orthogonal test. According to the experiment results, the order of influence was: distillation time, sodium chloride solution concentration, soaking time, material-liquid ratio. The optimum condition determined by orthogonal test was 3.0% sodium chloride solution in the solid-liquid ratio of 1:16 and distillation time was 1.5h without soaking. Under this condition, the extraction yield of essential oil from Tribute Citru peel reached 9.29%.
