Test example 1

And (3) determining the sweetness and taste attenuation conditions of the tipping paper I-V for the cigarettes and the tipping paper A-D for the cigarettes.

The determination method comprises the following steps: the tipping paper for the cigarettes is stored for 4 months at room temperature, the sweetness mouthfeel of the tipping paper for the cigarettes before and after storage is evaluated and scored by 7 professionals with sensory evaluation qualification, the fullness is 5 points, and the average result is obtained and is shown in table 1.

TABLE 1 sweetness taste score before and after storage of tipping paper for cigarettes

The printing surface refers to the surface of the cigarette tipping paper which is directly contacted with the oral cavity, and the non-printing surface refers to the surface used for wrapping the filter stick forming paper and the cigarette paper.

As can be seen from table 1, compared with the tipping paper for cigarettes of the comparative example, the difference of sweetness mouthfeel scores of the printing surfaces before and after storage of the tipping paper for cigarettes is smaller, which indicates that the sweetness mouthfeel attenuation degree of the tipping paper for cigarettes is lower; meanwhile, compared with the tipping paper for the cigarette in the comparative example, the difference of sweetness and mouthfeel scores of the non-printing surface before and after storage of the tipping paper for the cigarette is smaller, which shows that the tipping paper for the cigarette is less prone to migration of sweet components to the non-printing surface.
