Embodiment 1

[0019] (1) After the coffee beans are crushed and passed through a 100-mesh sieve, the coarse coffee bean powder is taken for fermentation treatment with Geotrichum candidum.

[0020] (2) Take the coarse powder after treatment, accurately weigh 500g of the above coffee bean powder and evenly mix in 2.5g of iso-Vc sodium, put the mixed coffee bean powder into an ultrasonic cell pulverizer for processing, and the ultrasonic treatment temperature is 40°C , The ultrasonic power is 400W, and the processing time is 6min.

[0021] (3) Pour 500 g of the processed coffee bean powder into the barrel, then put the barrel into the extraction kettle, and put 40 g of dehydrated alcohol accounting for 8% of the coffee bean powder mass into the entrainer tank as an entrainer. Start the carbon dioxide refrigeration system and circulation system, control the pressure of the extraction kettle to 20MPa, and the temperature to 35°C. The pressure of separation tank 1 is 7MPa, the temperature is 40...

Abstract

The invention discloses a method for extracting caffeol with supercritical carbon dioxide. The method comprises the following steps: (1) crushing coffee bean, and then performing geotrichum candidum fermentation treatment; (2) weighing the fermented coffee bean powder, and performing ultrasonic treatment; (3) performing supercritical CO2 extraction on the coffee bean powder treated in step (2) so as to obtain the caffeol. The invention further provides application of the caffeol extracted with the supercritical carbon dioxide for cigarettes, the caffeol is diluted into a solution of which the mass concentration is 1% by using ethanol of which the mass concentration is 95%, and then, the solution is added to the tobacco shreds of the cigarettes, which accounts for 0.01-0.03% of the weight of the tobacco shreds. The caffeol prepared by the method disclosed by the invention is added to the tobacco shreds to coordinate with the natural aroma of tobacco so as to perform the functions of stimulating the spirits, restoring consciousness and allaying tiredness, and besides, the caffeol can also enrich and cooperate the aroma of the tobacco, and reduce the simulating effect; particularly, a micromolecular organic acid generated by degrading oil and fat ingredients can effectively improve the aroma of the tobacco and can reduce the stimulation.

Description

technical field [0001] The invention belongs to the technical field of extracting flavors of cigarettes, in particular to a method for extracting coffee oil with supercritical carbon dioxide and its application in cigarettes. Background technique [0002] (Coffea) is a dicotyledonous plant, Rubiaceae. Evergreen shrubs or small trees. Leaves are opposite, leathery, long ovate. Peanuts in leaf axils, white. The berries are oval, dark red, and contain two seeds. Native to tropical eastern Africa. Brazil is the world's largest coffee producer and exporter. China has successively introduced three kinds of small-fruited coffee, medium-fruited coffee and large-fruited coffee from Ethiopia and other places, and cultivated in Hainan, Yunnan and Taiwan. Coffee seeds are roasted and ground to make a beverage. Coffee seeds contain a kind of caffeine, which can penetrate into the whole body in about 5 minutes after drinking, which can make people excited for 3 to 5 hours without f...
