Embodiment 1

[0024] Example 1: Firstly, papaya leaves were ground and pulverized, 20 g of ground papaya leaf powder was put into a 500 mL flask, 120 g of 50% ethanol was added, and ultrasonic extraction was carried out in a constant temperature water bath at 60°C for 6 hours. Then the extract was centrifuged with a high-speed centrifuge, and the supernatant was concentrated into a paste, which was transferred to a brown glass bottle and sealed for later use.

[0025] The prepared papaya leaf paste concentrated solution was dissolved with 70% ethanol and diluted into a papaya leaf extract solution; then 100g shredded tobacco was weighed, and 0.02g of papaya leaf extract was weighed according to the application ratio of 0.02%; The diluted solution is evenly sprayed on the weighed shredded tobacco, and then the sprayed shredded tobacco is placed in a constant temperature and humidity box at a temperature of 22 ℃ ± 1 ℃ and RH60% ± 2% for 48 hours to make cigarettes.

[0026] The results of add...

Embodiment 2

[0027] Example 2, first weigh 50 g of papaya leaves and put them into a 2L flask, add 350 g of 65% ethanol, stir and extract in a constant temperature water bath at 65°C for 8.5 hours. The extract was filtered to obtain papaya leaf extract, which was then transferred to a brown glass bottle and sealed for later use.

[0028] Weigh 100g shredded tobacco first, then weigh 3.5g of the above-mentioned papaya leaf extract, and spray the extract evenly on the weighed shredded tobacco, then place the sprayed shredded tobacco at a temperature of 22°C±1°C and RH60%± 2% constant temperature and humidity box for 48 hours to make cigarettes.

Embodiment 3

[0029] Example 3, first weigh 100 g of papaya leaves, put the weighed 100 g of papaya leaves into a 2L flask, add 1000 g of water, and stir and extract in a constant temperature water bath at 80°C for 8 hours. Then the extract was filtered and transferred to a brown glass bottle and sealed for later use.

[0030] Weigh 100g shredded tobacco, weigh 4.5g of the above-mentioned papaya leaf extract stored in the brown bottle according to the application ratio of 4.5%, and then spray the weighed extract evenly on the shredded tobacco; place the shredded tobacco sprayed at a temperature of 22 ℃ ± 1 ℃ and RH60% ± 2% constant temperature and humidity box for 48 hours to make cigarettes.

[0031] The smoking evaluation results of adding papaya leaf extract to test cigarettes show that: papaya leaf extract can harmonize with the aroma of cigarettes, improve aroma quality, enrich smoke aroma, clear aroma, soft and delicate smoke, good lingering feeling, and improve smoking. The satisfac...

Abstract

The invention discloses a preparation method for a carica papaya leaf extract and an application for the same in cigarettes. According to the application, after being extracted from carica papaya leaves with water or alcohols with different concentrations, the carica papaya leaf extract is weighed in a ratio occupying 0.02-5% of the weight of produced tobacco shreds and uniformly sprayed on the produced tobacco shreds, so as to prepare a cigarette. The result of a smoke panel test on the addition of the carica papaya leaf extract in a tested cigarette indicates that: the carica papaya leaf extract is capable of harmonizing with cigarette aroma, improving aroma quality, enriching cigarette aroma, achieving clear aroma, distinct personality, soft and smooth smoke and good lasting feeling, improving smoking satisfaction, obviously reducing irritation, increasing smoking comfort level, and keeping comfortable aftertaste and moderate concentration and strength.
