The raw material formulations of examples 1 to 3 and comparative examples 1 to 3 and the contents of smoke agent, lyocell fiber and softwood fiber in the reconstituted tobacco products are shown in table 2 below.
TABLE 2
Analytical testing
Item 1: content of smoke agent
In appearance, the reconstituted tobacco products of examples 1 to 3 and comparative examples 1 to 2 were dry in surface and no liquid exuded. The reconstituted tobacco product of comparative example 3 had a small amount of residual liquid exuded from the surface.
The content of the smoke agent in the reconstituted tobacco products of examples 1 to 3 and comparative examples 1 to 3 was measured according to YC/T243-2008 "gas chromatography for measurement of 1, 2-propanediol and glycerol in tobacco and tobacco products", and the results are shown in table 2.
Item 2: amount of smoke and sensory quality
The reconstituted tobacco leaves of the examples 1 to 3 and the comparative examples 1 to 3 are cut into tobacco shreds with the width of 0.8 to 1mm, the tobacco core section of the existing heating non-combustion tobacco product IQOS/Heat sticks in the market is replaced, and the filling amount of the tobacco shreds is 0.32 g/cigarette.
7 professional tobacco smokers were organized, smoked the above tobacco products which were not burned by heating, and the amount of smoke and the sensory quality were scored, and the scores were averaged.
Wherein, the sensory quality is divided into 100 points, the scoring standard approximately refers to GB 5606.4-2005 sensory technical requirement of cigarette part 4, but the sensory quality evaluation of the heating non-combustible tobacco product mainly comprises the following indexes of' smoke temperature (divided into 20 points); the amount of smoke (full 20 min); the number of suction ports (full 20 minutes); the style of aroma (16 points full); satisfaction (8 points of satisfaction); comfort (full 8 points); odor (score 8 full) ", and total score 100. The scoring results are shown in the table below.
TABLE 3
As shown in tables 2 and 3, the reconstituted tobacco of examples 1 to 3 used for heating a non-combustible tobacco product did exhibit the following advantageous effects, as compared to comparative examples 1 to 3:
1) the reconstituted tobacco can contain more smoke agent, and the surface is dry without liquid exudation;
2) the reconstituted tobacco is used for heating non-combustible tobacco products, and the smoke amount is higher;
3) the product is used for heating non-combustible tobacco products, and has the advantages of good tobacco fragrance, clean aftertaste and better sensory quality.
The experimental effect can deduce that the addition of the lyocell fibers improves the overall performance of the reconstituted tobacco, increases the smoke amount and improves the sensory quality.
