Problems solved by technology

However, the method of steam distillation has the following defects: 1. Because steam distillation is high-temperature distillation, it is easy to change the structure of some heat-sensitive substances or react with each other, thereby changing the structure and composition of natural components.
2. Steam distillation takes a long time and consumes a lot of energy
3. The steam distillation method has a low yield of volatile oil from burdock fruit, about 0.2%.
As mentioned above, none of these ingredients are suitable for direct application in cigarettes

Embodiment 1

[0022] Embodiment 1 Chinese herbal medicine burdock fruit is crushed into coarse powder passing through a 100-mesh sieve, soaked overnight with 6 times the amount of medical grade petroleum ether with a boiling range of 60-90° C., reflux extraction for 5 hours to degrease, filter, and dry the filter residue; Put it into a supercritical extraction kettle for supercritical extraction. The extraction conditions are: the extraction temperature of the carbon dioxide fluid is 45°C, the pressure is 25MPa, the flow rate of carbon dioxide is 30kg / h, and the flow rate of 95% ethanol as an entrainer in the auxiliary pump is 10kg / h; The separation temperature of the kettle is 35°C, the pressure is 8MPa; the extraction time is 60min. The light yellow oil separated in the separation kettle is the volatile oil of Arctium chinensis.

Abstract

The invention discloses a method for extracting volatile oil by supercritically extracting pre-degreased great burdock achene and application, and belongs to spice extraction technology in the technical field of cigarettes. The method comprises the following steps of: pre-degreasing the great burdock achene; and then extracting the volatile oil by the supercritical extraction method. The prepared great burdock achene volatile oil is diluted into 1 percent by 95 percent ethanol and then the diluted great burdock achene volatile oil in an amount which is 0.01 to 0.05 percent based on the weight of cut tobacco is added into the cut tobacco. The product obtained by the method has high yield, contains a great number of aroma-enhancing materials required by the tobacco and does not contain materials which influence smoke flavor and quality of the tobacco. The method can improve the quality of the tobacco product when used for the tobacco.

Description

technical field [0001] The invention belongs to the fragrance extraction technology in the technical field of cigarettes, and specifically relates to a method for extracting volatile oil from a plant medicine burdock fruit by supercritical extraction, and the application of the extracted volatile oil as an additive for cigarettes. Background technique [0002] In the prior art, Burdock Fructus is recorded in "Pharmacopoeia of the People's Republic of China (Part One)" (2005 Edition), which is the dry and mature fruit of Arctium lappa L., a composite plant. Harvest the infructome when the fruit is ripe in autumn, dry it in the sun, and lay down the fruit. It is distributed all over the country, and it was first recorded in "Bielu of Famous Doctors" and listed as a medium grade. Burdock seed is also known as: evil real, mouse sticky, millet sticky, vigorous, bat thorn, Mao Ranran, black wind, hair awl, sticky cubeb, rat tip, curved hook, ten thousand hooks, big cow , Niuzi; ...
