The present invention provides an additive for improving sensory quality of cut rolled stems, which is composed of histidine, phenylalanine, alanine, tryptophan, strong ammonia water, invert sugar, water and glycerol.
In one embodiment of the additive for improving sensory quality of cut rolled stems of the present disclosure, the mass ratio of histidine, phenylalanine, alanine, tryptophan, strong ammonia water, invert sugar, water and glycerol is (5-20): 10-30): 20-60: (30-60).
In order to more effectively improve the sensory quality of the cut rolled stems, the mass ratio of histidine to phenylalanine to alanine to tryptophan is 1:1:1: 1.
In order to effectively improve the sensory quality of the cut rolled stems, the mass ratio of histidine, phenylalanine, alanine, tryptophan, strong ammonia water, invert sugar, water and glycerol is 2:2:2:2:4:6: 5.
In order to effectively improve the sensory quality of the cut stems, the mass fraction of the concentrated ammonia water is more than 28 percent.
The experimental analysis on the smoke addition of the additive for improving the sensory quality of the cut stems shows that the release amount of low-molecular aldehydes such as formaldehyde, acetaldehyde, acrolein, butanedialdehyde and the like in the smoke of the cut stem cigarette added with the additive for improving the sensory quality of the cut stems is obviously reduced, and the aldehydes can cause the smoke to generate rough feeling and uncomfortable feeling, and belong to substances which are not beneficial to the taste of tobacco.
The release amount of substances such as 5-hydroxymethylfurfural, acetic acid, furfural, furanone, 5-methylfurfural, furfuryl alcohol, hydroxy maltol, 2, 6-dimethylpyrazine, methylpyrazine, 2-methylpyridine acetic acid, trimethylpyrazine, pyridine and the like in the smoke of the cut stem cigarette is increased to a certain extent, the substances can be coordinated with the natural fragrance of tobacco, and the substances are beneficial to the fragrance, the taste and the mouthfeel of the cigarette.
The present disclosure also provides a method for preparing an additive for improving sensory quality of cut stems, comprising the steps of:
step (1): mixing histidine, phenylalanine, alanine, tryptophan, strong ammonia water, invert sugar, water and glycerol uniformly to obtain the mixture.
Step (2): heating the mixture in water bath at 80-140 deg.C for 4-10 h to obtain the additive for improving sensory quality of cut stems.
In order to improve the controllability of the reaction and to more effectively improve the organoleptic quality of the cut rolled stems, the heating temperature in step (2) is less than or equal to 120 ℃.
In order to improve the controllability of the reaction and more effectively improve the sensory quality of the cut stems, the heating time in the step (2) is greater than or equal to 6 hours.

And heating the mixture in water bath at 100 ℃ for 6 hours, and cooling to room temperature to obtain the additive S1 for improving the sensory quality of the cut stems.
Weighing additive S1 for improving sensory quality of cut rolled stem at a ratio of 1% of cut rolled stem weight. And (3) placing the cut stems sprayed with the additive S1 for improving the sensory quality of the cut stems in a leaf storage cabinet for 3 hours to obtain the No. 1 modulated cut stems.
Example 2
Weighing raw materials including histidine, phenylalanine, alanine, tryptophan, strong ammonia water, invert sugar, water and glycerol according to the mass ratio of 8:8:8:8:8:16:24:20, and uniformly mixing to obtain a mixture. And heating the mixture in water bath at 120 ℃ for 8 hours, and cooling to room temperature to obtain the additive S2 for improving the sensory quality of the cut stems.
Weighing additive S2 for improving sensory quality of cut rolled stem at a ratio of 1% of cut rolled stem weight. And (3) placing the cut stems sprayed with the additive S2 for improving the sensory quality of the cut stems in a leaf storage cabinet for 3 hours to obtain the 2# modulated cut stems.
Comparative example 1
Uniformly spraying water on the cut stems by a feeding device according to the proportion of 1% of the weight of the cut stems, and placing the cut stems in a leaf storage cabinet for 3 hours to obtain blank cut stems.
Preparing the No. 1 modulated cut stems, the No. 2 modulated cut stems and the blank cut stems into cut stem cigarette samples, and performing smoking evaluation on the cut stem cigarette samples, wherein the smoking evaluation results are shown in Table 1. As can be seen from table 1, the additive for improving the sensory quality of cut stems of the present disclosure can improve the aroma, the smoke flavor, reduce the miscellaneous gas and the dry feeling, and improve the aftertaste.
