Comparative example 1
The comparative example 1 of the present invention provides a method for preparing a tobacco sheet without adding natural sepiolite inorganic fiber, which is different from the example 5 in that the natural sepiolite inorganic fiber is not used in the step (3), softwood fiber in an amount of 1.5% by weight relative to the weight of tobacco powder is weighed, the remaining steps are the same, a tobacco product which is not combusted by heating is prepared and marked as L6, the physical properties of the tobacco product are measured, and an electrically heated low-temperature cigarette is prepared for sensory smoking.
Example 1 ~ the physical properties of the electrically heated low temperature cigarettes prepared in example 5 and comparative example 1 are shown in table 1, and the sensory comparative smoking results are shown in table 2.
TABLE 1 comparison of physical Properties of electrically heated Low temperature cigarettes prepared by different preparation methods
| Sample (I) | Tensile Strength/KN. m-1 | Filling value/cm3·g-1 | White point/m-2 |
| L1 | 1.24 | 2.71 | 4 |
| L2 | 1.39 | 2.73 | 5 |
| L3 | 1.63 | 2.69 | 4 |
| L4 | 1.13 | 2.64 | 2 |
| L5 | 1.77 | 2.72 | 0 |
| L6 | 1.03 | 2.68 | 8 |
As can be seen from Table 1, the tensile strength of the sample is improved after the inorganic fiber of natural sepiolite is added, and the tensile strength of the sample is firstly increased and then tends to be flat as the dosage of the inorganic fiber is increased; for the filling value, the addition of the inorganic fiber of the natural sepiolite has no obvious influence on the filling value; after the dosage of the added softwood fiber is reduced, the number of white points of the sample is obviously reduced, and the tensile strength is still in a better level.
TABLE 2 sensory evaluation control of electrically heated low temperature cigarettes prepared by different preparation methods
| Sample (I) | Fragrance | Tuning by hand | Miscellaneous qi | Irritation property | Aftertaste |
| Original craft product | 0 | 0 | 0 | 0 | 0 |
| L1 | 0 | 0 | 0 | 0 | 0 |
| L2 | 0 | 0 | 0 | + | 0 |
| L3 | - | 0 | + | + | - |
| L4 | 0 | + | + | + | + |
| L5 | + | + | ++ | ++ | ++ |
Note: "0" means an initial value or no change; "+" indicates improvement; "+ +" indicates a significant improvement; "-" indicates that the index decreased.
As can be seen from table 2, the natural sepiolite inorganic fibers replace part of the added softwood fibers, so that the exogenous wood gas and the oral cavity residues are reduced, but the excessive use of the natural sepiolite inorganic fibers can reduce the aftertaste of cigarettes, and the proper use of the natural sepiolite inorganic fibers can improve the sensory quality of the special heating non-combustion sheet product.
The present invention is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modifications, equivalents, improvements and the like made to the above embodiments in accordance with the technical spirit of the present invention should be included in the scope of the present invention.
