Embodiment 1
[0068] The raw materials for extraction are frozen and crushed to 15 meshes of Yunnan plateau roses. The feeding amount is 200kg. The samples are crushed to 15-20 meshes and added to the ultrasonic extraction tank 1. Seal the feeding port and the discharging port, and add 5 times the weight of the rose sample. Ultrasonic extraction of methyl acetate at 45°C for 35 minutes. After the extraction, start the air compressor to pressurize the ultrasonic extraction tank, and let the extract pass through the filter sieve plate at the outlet and lead to the chromatography column for purification.
[0069] After the extract passed through the chromatographic column was transferred to the concentration tank, the temperature of the concentration tank was raised to 80° C., and at the same time, the vacuum pump was started to concentrate the extract until the methyl acetate was evaporated to dryness. Return the methyl acetate recovered after the sample concentration to the ultrasonic extract...
Embodiment 2
[0072]The rose absolute prepared by the above method is used in cigarette shreds, the rose absolute is added to the cigarette shreds at a ratio of 5 / 100,000 of the weight of the shredded tobacco, and the shredded tobacco is made into finished cigarettes for evaluation and smoking. The results show that: the rose absolute prepared by the present invention can effectively strengthen the rose fragrance characteristic of cigarette products, the aroma quantity and aroma quality of cigarette smoking are all improved, and it can also cover up the miscellaneous gas of cigarette smoking and improve cigarette smoking. The comfort is better than that of the control sample (i.e. the cigarette that does not add the rose absolute obtained by the present invention). or,
[0073] In the cigarette filter molding process, the rose absolute obtained by the present invention is added to the triacetin according to the 1wt% amount of the plasticizer triacetin, and then the triacetin added with the ...
Embodiment 3
[0076] During the preparation process of the electronic cigarette liquid, the rose absolute of the present invention is added to the rose flavored electronic cigarette liquid in a proportion of 5% by weight. The result shows: the total score of the rose absolute of the present invention is higher, and the advantage mainly shows in that the aroma quality is good, and the amount of aroma is sufficient; secondly, it shows that the miscellaneous gas is light, and the aftertaste is cleaner, which is better than that of the contrast sample (that is, the product obtained without adding the present invention) e-cigarettes of rose absolute).
