TABLE 7 sensory evaluation of sweetness

Smoke amount detection: the prepared tobacco shreds of application examples 1-26 and comparative examples 1-3 were added to a heated non-burning appliance, heated, and smoked on an electronic cigarette smoking machine to trap the aerosol with a Cambridge filter. Weighing the weight change of the Cambridge filter before and after being captured by the front 15 ports by a weighing method to be used as the total smoke amount; then, the smoke amount of the 1 st port and the smoke amount of the 15 th port were measured in the same manner, and the change in the smoke amount between the 15 th port and the 1 st port was calculated and recorded as a change rate, which was (smoke amount of the 1 st port-smoke amount of the 15 th port)/smoke amount of the 1 st port × 100%.

The results of the performance measurements are shown in Table 8.

TABLE 8 results of Performance testing

In combination with application examples 1-26 and comparative examples 1-3, and in combination with table 8, it can be seen that when the product of the present application is smoked, the sweet and greasy feeling is reduced, the smoke amount of application examples 1-26 is significantly larger than that of comparative examples 1-3, and the reduction rate of the smoke amount of the 15 th mouth relative to that of the 1 st mouth in application examples 1-26 is significantly lower than that of comparative examples 1-3, which indicates that the product of the present application not only has stable smoke amount, but also has stable smoke generation and can continuously generate smoke.

By combining application examples 1-2 and application example 3 and combining table 8, before the atomizing agent is sprayed on the tobacco shreds, the tobacco shreds are processed according to the sequence of freeze-drying, moisture balancing and steam explosion, the smoke quantity is large, probably because the freeze-drying treatment can effectively remove moisture and other volatile substances in the tobacco shreds, air holes on the surfaces of the tobacco shreds are activated, the freeze-dried tobacco shreds are rewetted and then subjected to steam explosion treatment, the internal microstructures of the tobacco shreds are effectively damaged, and then the atomizing agent is sprayed, so that the absorption quantity of the tobacco shreds on the atomizing agent is greatly improved, and the smoke quantity is favorably improved; and if do not carry out rewetting after freeze-drying, then can make the inside structure damage of pipe tobacco too serious in steam explosion treatment, and cause the pipe tobacco to the reduction of atomizing agent absorption to reduce cigarette fog volume.

Combining application examples 3-21 with comparative examples 1-3, and combining table 8, it can be seen that the amount of smoke in application examples 3-21 is significantly greater than in comparative examples 1-3, and the amount of smoke is not much different in application examples 3-16, the atomization component in application examples 3-16 is any two of light component, medium component and heavy component, the amount of smoke in application examples 17-21 is improved compared with application examples 3-16, the atomization component in application examples 17-21 contains three of light component, medium component and heavy component, which shows that the light component, the medium component and the heavy component are compounded to be used as the atomization component, the smoke amount can be effectively increased probably because the three components are compounded, the boiling point range of the fogging components is widened, the continuity of the boiling points among the components is improved, and the smoke stability is improved while the smoke amount is increased.

In combination with application examples 6-10 and table 8, it can be seen that the amount of smoke in application examples 6-8 is improved, the rate of change is reduced, and the effect in application example 8 is better, compared with application examples 9-10, which indicates that the proportion of the fogging component in application example 8 is better; application example 10 is superior to application example 9 in the effect probably because the content of the light component in application example 9 is too small, resulting in discontinuity of the fogging between the fogging component and glycerin, and thus causing a decrease in the amount of smoke.

In combination with application examples 11 to 13 and table 8, it can be seen that the amount of smoke in application examples 11 to 12 is increased and the rate of change is reduced compared to application example 13, and the effect in application example 11 is better than that in application example 12, which indicates that the proportion of the fogging component in application example 11 is better.

In combination with application examples 14-16, and in combination with Table 8, it can be seen that the amount of smoke in application examples 14-15 was increased, the rate of change was reduced, and the effect in application example 14 was superior to application example 15, probably because the relatively higher content of components in application example 14 resulted in more continuous fogging between the fogging component and the glycerin.

In combination with application examples 17-21 and table 8, it can be seen that the amount of smoke in application examples 17-19 is increased and the rate of change is reduced relative to application examples 20-21, which indicates that better effects can be achieved by the application in the proportion of the present application; the effect in application example 20 was superior to application example 21, probably because the content of the medium component in application example 21 was too low, which in turn served to provide some connection between the light component and the heavy component, which may result in discontinuous fogging.

In combination with application examples 22-26 and table 8, it can be seen that the smoke amount in application examples 22-26 is relatively high, and the decrease rate of the smoke amount in the 15 th port relative to the smoke amount in the 1 st port is probably due to the fact that 1, 3-dimethyl-2-imidazolidinone is compounded with ethanol to adjust the viscosity, and the smoke amount is matched with components in the middle component and the heavy component, so that the viscosity of glycerin and the components in the light component are reduced, the fluidity of the atomizing agent is improved, the atomizing agent can be timely supplemented to the vicinity of a heating filament to be heated, the continuous atomizing capability of the atomizing agent is increased, the atomizing agent can generate obvious smoke at the heating temperature of a cigarette which is not heated, the heated smoke amount of the atomizing agent is improved, the fluidity of the atomizing agent can be effectively improved, and the atomizing capability of the atomizing agent is improved.
