Abstract
The invention provides a method of extraction of orange blossom essential oil. The method consists of steps 1, sprinkling the entraining agent that is 0.3-0.5% of the weight of fresh orange blossoms into the fresh orange blossoms, adding the fresh orange blossoms to the extraction kettle, and then using hypercritical carbon dioxide fluid for continuous cyclic extraction; the entraining agent is formed, by mass, with 65-70 parts of ethanol, 2-4 parts of triethanolamine, and 0.2-0.4 part of petroleum ether; 2, pouring the carbon dioxide fluid after extraction to a separator for separation; flow of carbon dioxide fluid is 12-15 kg/h, separator pressure is 6-7 MPa, and the temperature is 35-40 oC; extracting the fluid for 1.5-2.5 h, and discharging the extractant from the bottom of the separator to get the orange blossom essential oil through oil and water separation after standing. The orange blossom essential oil obtained using the method in the invention has high purity and long-lasting fragrance.
