Abstract

Essential oil was extracted from peel of citrus by the methods of supercritical CO2 extraction and steam distillation extraction.The extraction yield of two methods was equal,the highest yield was 1.2%.The quality of the volatile oil extracted by steam distillation extraction was better than those extracted by supercritical CO2,and was light yellow fluidity liquid and smell fresh citrus scent.Technological process of steam distillation extraction was simple than that of supercritical CO2 extraction.The essential oi extracted by supercritical CO2 was dark yellow semi-liquid liquid impurities.
