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

Abstract

The invention discloses a method for extracting volatile oil from geotrichum candidum through the fermentation of burdock by utilizing a supercritical extraction method and an application, belonging to the technical field of tobacco spice extraction. The method of the invention adopts the geotrichum candidum to ferment and degrade the grease components harmful to the sensory quality of tobacco, carries out the supercritical carbon dioxide extraction to obtain the burdock volatile oil after the fermentation, has the advantages of effective measures and obvious technical effects, and is simple in operation and easy in implementation, and the extracted volatile oil has the advantages of high yield and good quality. The obtained burdock volatile oil contains more fragrant components same or similar to the tobacco, can be coordinated with the initial fragrance of the tobacco when being added to tobacco shreds, and has the effect of enriching and coordinating the tobacco fragrance, promoting the quality of the tobacco fragrance and reducing the simulation. Particularly, the micro-molecular organic acid generated from the grease components after degradation can effectively enhance the tobacco fragrance and reduces the simulation.

Description

technical field [0001] The invention belongs to the technical field of extracting flavors of cigarettes, and specifically relates to a method for extracting volatile oil from herbal medicine Arctium candidum by fermenting Geotrichum candidum, and using 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; its Mongolian medicine...
