Aerosol amount, aroma concentration, aroma reduction degree, aerosol humidity, throat-hitting feeling, satisfaction, harmony and aftertaste are positively rated, for example, the higher the harmony, the higher the score. Off-flavor and sweet greasy taste are negative scores, e.g., the heavier the sweet greasy taste, the lower the score. The sensory quality of the examples and the control were scored by 7 persons having sensory evaluation qualification, and the average value was calculated. The control represents a commercially available tobacco-flavored aerosol-generating substrate.

As can be seen, the aerosol-generating substrates prepared in examples 1, 2 and 3 have small molecular weight due to removal of macromolecular substances and heavy component impurities, are not easy to block capillary pores of the atomizing core, and have high atomizing efficiency; the boiling point is low, and the aerosol is easily formed by heating and atomizing, so that the generated aerosol quantity is large. The amount of generated aerosol is large, the amount of aerosol inhaled by each mouth of a user is increased, the smelled aroma concentration is stronger, the corresponding throat hitting feeling is stronger, the satisfaction is higher, the harmony is better, the aftertaste is better, the offensive odor is less, and the sensory quality is better.
The aerosol-generating substrates prepared in examples 1, 2 and 3 above were compared with commercially available tobacco flavoured aerosol-generating substrates for resistance change and temperature impact before and after the mouth of the ceramic atomising core die 1500. Table 2 shows the effect of different aerosol-generating substrates on the resistance and temperature of the ceramic atomizing wick.

As shown in table 2, the parallel samples of example 1, example 2 and example 3 above produced aerosol-generating substrates in which the resistance of the atomising cores after drawing 1500 puff varied significantly less than the parallel samples of the control sample and the temperature was also significantly lower than the control sample. Therefore, the aerosol-generating substrates prepared by the parallel samples of the embodiments 1, 2 and 3 have small molecular weight due to the removal of macromolecular substances and heavy component impurities, are not easy to block capillary pores of the atomizing core, and have high atomizing efficiency; the boiling point is low, the aerosol is easy to be formed by heating and atomizing, and the scorching is not easy to occur due to repeated heating on the atomizing core; and then the change of the resistance value of the atomizing core is small, and the service life of the atomizing core is prolonged. The typical atomisation temperature of an atomiser is from 280 to 300 c and the temperature of the atomising core in the examples is mostly below 280 c, indicating that the aerosol-generating substrate provided herein has a high suitability for use with an atomiser.
The aerosol-generating substrates prepared in example 1, example 2 and example 3 above were compared with the amount of aerosol generated by commercially available tobacco-flavoured aerosol-generating substrates. Table 3 is a comparative test of aerosol volume in the mouth of the puff 200.
TABLE 3
As shown in table 3, the aerosol-generating substrates prepared in examples 1, 2 and 3 produced aerosol amounts from 50 th to 200 th (step size 50) that were greater than the control, it can be seen that the aerosol-generating substrates provided by the present application had a low molecular weight, less tendency to clog the capillary pores of the atomizing wick and high atomization efficiency compared to commercially available tobacco-flavored aerosol-generating substrates due to the removal of macromolecular substances and heavy component impurities; the boiling point is low, and the aerosol is easily formed by heating and atomizing, so that the generated aerosol quantity is larger.
The aerosol-generating substrates prepared in example 1, example 2 and example 3 above were compared with the carbon deposition on the atomising core of commercially available tobacco flavoured aerosol-generating substrates.
Referring to fig. 3 to 6, fig. 3a is an image of an embodiment of an atomized core according to embodiment 1, fig. 3b is an image of another embodiment of an atomized core according to embodiment 1, fig. 4a is an image of an embodiment of an atomized core according to embodiment 2, fig. 4b is an image of another embodiment of an atomized core according to embodiment 2, fig. 5a is an image of an embodiment of an atomized core according to embodiment 3, fig. 5b is an image of another embodiment of an atomized core according to embodiment 3, fig. 6a is an image of an embodiment of an atomized core according to a control sample, and fig. 6b is an image of another embodiment of an atomized core according to a control sample.
The carbon deposition on the atomized cores of example 1, example 2 and example 3 and the control were observed under a 20-fold microscope. Example 1, example 2 and example 3 generated a small amount of carbon deposition on the heat generating film of the atomizing core; the control sample generates a large amount of carbon deposition on the heating film of the atomizing core and the atomizing surface of the atomizing core. Therefore, the aerosol generating substrates prepared in the embodiment 1, the embodiment 2 and the embodiment 3 have small molecular weight, are not easy to block capillary pores of the atomizing core and have high atomizing efficiency because macromolecular substances and heavy component impurities are removed; the aerosol has low boiling point, is easy to be heated and atomized to form aerosol, is not easy to be heated repeatedly on the atomizing core to generate scorch, and has obvious effect on improving the carbon deposition condition of the aerosol generating substrate in the ceramic atomizing core.
In summary, the aerosol substrate provided by the application has the advantages that the macromolecular substances and heavy component impurities are removed, the light component substances are retained, the molecular weight is small, the capillary pores of the atomizing core are not easy to block, and the atomizing efficiency is high; the boiling point is low, the aerosol is easy to be formed by heating and atomizing, and the carbon deposition is not easy to be formed by coke paste generated by repeated heating on the atomizing core; while also enhancing the characteristic aroma and taste of the aerosol-generating substrate.
The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings are included in the scope of the present disclosure.
