Abstract

The invention discloses a method for extracting zanthoxylum bungeanum essential oil by utilizing vegetable oil and supercritical CO2. The method comprises the following steps: fully crushing zanthoxylum bungeanum particles to be extracted into powder; adding vegetable oil into extraction kettles containing zanthoxylum bungeanum powder according to a preset proportion; introducing supercritical CO2into the extraction kettles for extraction; and carrying out separation through a separation tower after extraction to obtain a finished zanthoxylum bungeanum oil product which can be directly used as a food additive. Vegetable oil and zanthoxylum bungeanum are extracted together according to a certain proportion, zanthoxylum bungeanum essential oil is dissolved in the vegetable oil in the extraction process, the prepared product can be directly sold, and the finished product is transparent, free of insoluble substances, free of sediment and good in taste. The six extraction kettles are communicated with one another through six extraction passages for circular extraction, so that extraction is uninterrupted in time, and the extraction efficiency is improved.
