Abstract
The invention belongs to the technical field of chemical engineering, and particularly relates to a method for extracting pomelo peel essential oil. The method comprises the following steps: S1, pre-treating pomelo peel, namely drying pomelo peel, and grinding; S2, carrying out supercritical CO2 extraction, namely putting the pomelo peel particles obtained in the step S1 into an extraction kettle, and extracting with supercritical CO2 fluid for 30-60 minutes at a temperature of 45-55 DEG C, pressure of 18-25MPa and CO2 flow rate of 35-40L/h; and S3, collecting essential oil extracted in the step S2 to obtain the pomelo peel essential oil after CO2 is completely volatilized. The pomelo peel essential oil obtained by the method has the advantages of high quality, rich fragrance, pure pomelo fragrance, no foreign odor, proper color and good transparency. The pomelo peel essential oil obtained by the method has a high pomelo peel yield reaching 5.16 percent.
Description
Technical field
