Sensory evaluation test

The licorice root oil prepared in examples 10 to 20 and comparative examples 1 to 6 was subjected to the following sensory evaluation tests, and the evaluation results are shown in Table 4.

170 smokers were randomly selected and divided into 17 groups of 10 smokers, and each group of smokers smoked the same licorice root hybrid fruit tobacco tar, and the smoking experience was scored according to the criteria in table 1, and the average score of 10 smokers was recorded in table 4 as the sensory evaluation score of the licorice root hybrid fruit tobacco tar.

TABLE 4 sensory evaluation record sheet

Referring to Table 4, as can be seen from the comparison between example 2 and examples 10 to 12, the licorice extract was added in an amount of 1 part, so that the tobacco tar was best tasted and smoked. Combining comparative example 1 and comparative example 2, it can be seen that licorice extract provides tobacco tar with higher sweetness, a more pleasant flavor, less off-flavors, and a more coordinated aroma than artificial sweeteners such as sodium cyclamate, saccharin, and the like. In combination with comparative example 3, the liquorice extract is added into the tobacco tar, so that various sensory experiences of the tobacco tar can be greatly improved, and the requirements of smokers can be met.

The sensory evaluation results of examples 13 to 17 indicate that the licorice extract in the glycyrrhiza uralensis hybrid fruit tobacco tar can replace the artificial synthetic sweetener to provide proper sweet taste for the smoke, and does not have foreign tastes such as bitter taste and metal taste; the synergistic effect of the raw materials makes the fruit fragrance of the smoke soft, coordinated and pleasant, and the smoke has lasting fragrance and cool mouthfeel.

As can be seen from comparison of examples 18 and 19 with example 2, when the licorice hybrid fruit tobacco tar is prepared, the licorice hybrid fruit tobacco tar prepared by 80 parts of tobacco tar mother liquor and 20 parts of fruity essence has better overall flavor and mouthfeel.

As can be seen from the comparison between example 20 and example 2, the licorice mixed fruit tobacco tar has a longer aging time, a stronger flavor, less foreign flavor, better harmony, less irritation, and a longer lasting flavor.

As can be seen from comparison of comparative example 4 with example 11, when menthol was used alone as a cooling agent, the tobacco tar had a poor cooling sensation and a strong irritation; in combination with comparative example 5, it was found that the smoke oil had a stronger cooling sensation than menthol but a poorer cooling sensation than the combination of the three cooling agents when WS-23 and WS-3 were used as the cooling agents. Therefore, the menthol, the WS-23 and the WS-3 are used as the mixed cooling agent, so that fresh, mild, rich and lasting cooling can be generated, the stimulation of smoke to the throat is reduced, the effect of enhancing the cooling is achieved, and the requirement of smokers is met.

Compared with the comparative example 6 and the example 12, the fact that linalool, eugenol, caryophyllene and benzyl acetate are added into the glycyrrhiza uralensis mixed fruit tobacco oil can endow smoke with richer and layered aroma, reduce foreign flavor, enable the aroma to be more durable and improve the experience of smokers.
