In the cigarette paper printing process, pattern design is carried out, a template is engraved, roller shaft embossing is adopted, the four color-changeable morning glory spice coating liquids are respectively printed on cigarette paper to obtain four color cigarette papers containing the color-changeable morning glory spice, and then the four cigarette papers are further rolled into cigarettes to be used as test samples, and the test cigarettes, the control cigarette 1#, the control cigarette 2#, and the control cigarette 3#, respectively are marked; and comparing the cigarette paper which is not coated with any color-changeable morning glory spice coating liquid with blank cigarettes;
(3) The evaluation results are shown in Table 1.
In terms of appearance, compared with a blank cigarette, the cigarette paper of the test cigarette and the control cigarette has blue-violet pattern.
In the aspect of smell, the control cigarette 1# prepared without any fermentation has no obvious smell when being smelled; the control cigarette 2# prepared by fermenting bacillus subtilis has obvious pungent odor when being smelled; the control cigarette 3# prepared by the fermentation of Pediococcus acidilactici has obvious sour taste when being smelled; the color-changeable morning glory spice prepared by utilizing the rhizosphere pseudomonas aeruginosa C1-9 has obvious faint scent, so that the test cigarette smell containing the color-changeable morning glory spice also has elegant fragrance.
In the aspect of cigarette smoking evaluation, when the cigarettes are ignited for smoking, compared with a blank cigarette, when the cigarettes are compared with the cigarettes 1# in smoking, the smoke flavor is not obviously increased, the miscellaneous gas is increased to some extent, and the smoke coordination is poor. When the control cigarette 2# prepared by fermenting bacillus subtilis is smoked, the smoke quantity is increased, but the miscellaneous gas and the irritation are obviously increased, and the smoke coordination is poor. When the control cigarette 3# prepared by the Pediococcus acidilactici fermentation is smoked, the smoke quantity is increased, the sour feel in the smoke is obviously increased, the miscellaneous gas and the stimulation are obvious, and the smoke coordination is poor. When the test cigarette prepared by fermenting the rhizosphere pseudomonas aeruginosa C1-9 is smoked, the faint scent and the flower fragrance in the smoke are obvious, the smoke fragrance is more mellow, the aftertaste is cleaner, and the smoking quality of the cigarette is obviously improved.
In terms of color change, the color of control cigarette # 1, which was not prepared without any fermentation, was not a pure bluish violet color, and the color changed but was not apparent and did not change to a reddish purple color during smoking. The starting colors of the control cigarettes 2# and 3# are blue-violet, and the color is dim; as the aspiration process proceeds, the color gradually changes to mauve, but the color change is not bright enough and the visual effect is not prominent enough. The initial color of the test cigarette is blue-violet, and the color is bright and pure; along with the suction process, the color gradually changes into bright and pure mauve; the color change is clear and the visual effect is prominent.

Example 5: the application of the color-changeable morning glory spice in the cigarette tows specifically comprises the following steps:
the color-changeable morning glory spice and the morning glory extract prepared in example 1, comparative example 2 and comparative example 3 were freeze-dried at a freezing temperature of-50 ℃, a hydrazine cooling temperature of-10 ℃, a vacuum degree of 20Pa and a freeze-drying final temperature of 28 ℃ respectively to obtain four color-changeable morning glory spice freeze-dried powders.
(1) After the acetate fiber master batch acetate diacetic tablet is prepared into slurry, 0.5 weight percent of the four color-changeable morning glory spice freeze-dried powders are respectively added and uniformly mixed, four blue-violet tows containing the color-changeable morning glory spice are formed through a tow production process, a filter tip rod containing the color-changeable morning glory spice is formed through a filter tip rod forming device, and then four cigarettes are further rolled. When the cigarette is lit for smoking, the smoke passes through the filter rod and the color of the filter rod tows changes. The smell results were substantially the same as in example 2. The color change was from blue-violet to purple and the four cigarettes were substantially the same as in example 2.
(2) The four kinds of color-changeable morning glory spice freeze-dried powder are respectively added with a small amount of ethanol for dilution and dissolution, and then are respectively added into plasticizer triacetin according to the proportion of 1wt%, so as to obtain four kinds of blue-violet triacetin containing the color-changeable morning glory spice, and the four kinds of color-changeable morning glory spice freeze-dried powder are sprayed into common tows through a filter tip forming device to form four kinds of filter tips containing the color-changeable morning glory spice, and are further rolled into cigarettes. When the cigarette is lit for smoking, the smoke passes through the filter rod and the color of the filter rod tows changes.
The smell results were substantially the same as in example 2. The color change was from blue-violet to purple and the four cigarettes were substantially the same as in example 2.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
