Abstract
The present invention discloses a method for extracting cinnamon oil; firstly, a cinnamon powder is mixed and conditioned with an aqueous solution of sodium salts, and the conditioned cinnamon powder is obtained thereafter; subsequently, the conditioned cinnamon powder obtained was frozen and then rapidly thawed, and the thawed cinnamon powder is obtained thereafter; finally, after the thawed cinnamon powder is mixed with a gaseous solvent, pressurized liquid extraction is performed, and then after separation the cinnamon oil is obtained. The method for extracting cinnamon oil from cinnamon at a low temperature adds an aqueous solution of sodium salts to condition the cinnamon powder, uses a slow freezing process and a rapid thawing process, and finally uses a gaseous solvent, which may gasify without heating to be separated from the extract; the extraction process is kept away from air, and the heat-sensitive components are not damaged.
