Description

Preparation method and application of burnt sweet tea flavored heating cigarette
Technical Field
The invention belongs to the technical field of tobacco flavors, and particularly relates to a preparation method and application of a burnt sweet tea flavor heated cigarette.
Background
Tea leaves, as one of three kinds of nonalcoholic beverages in the world, are widely favored because of having fragrant fragrance, containing tea polyphenols, amino acids and other nutrient substances and having various health-care functions of oxidation resistance, antibiosis and the like. The absolute content of the tea aroma substances in the tea is less, and generally only accounts for 0.01-0.05% of the mass of dry substances, but the tea aroma substances have great influence on the aroma quality of finished tea. At present, tea and related products thereof are mainly applied to the field of foods and are not related much in the field of tobacco flavors and fragrances.
The cigarette is heated by an external heat source, so that the aerosol, the fragrant substances and the nicotine in the cigarette are volatilized to form smoke similar to the traditional cigarette, and physiological satisfaction is achieved. The perfuming mode of the heated cigarette is mainly to apply essence and spice, and the perfuming of the auxiliary materials is relatively less.
CN108523197A provides a method for preparing low-temperature cigarettes with green tea style, which uses green tea and tobacco as main raw materials, combines the steps of green tea deactivation, rolling, drying and the like to obtain a mixed raw material of green tea and tobacco, and then combines a method for reproducing tobacco leaves to prepare a sheet to obtain the low-temperature cigarettes. The invention can obviously improve the smoking quality of low-temperature cigarettes, and has more obvious style characteristics of green tea compared with the method of directly adding green tea extract; the tobacco leaf and the green tea are mixed according to the proportion and then prepared according to the green tea step, so that the tobacco leaf can fully absorb aroma substances with low boiling point in the green tea, the smoking characteristic is more obvious, and the advantages of the green tea and the cigarette are fully mixed.
CN113528240A provides a preparation method of novel spice for heating cigarette with smoke regulation function, said preparation method comprises the following steps: fermenting the mixed raw material of Zimbabwe flue-cured tobacco and tea leaves at 25-30 ℃ by using bacillus, taking out a fermentation substrate, and extracting the fermentation substrate by using an ethanol solution with the concentration of 60-80 wt% to obtain a crude extract; filtering the crude extract with ultrafiltration membrane to obtain novel flavor. The invention utilizes the microbial fermentation technology and the novel extraction and separation technology to change the chemical components of the tobacco leaves and the tea leaves, extracts and separates novel latent fragrant substances from the tobacco leaves and adds the substances into the heated cigarette, thereby effectively reducing the release amount of harmful substances in the smoke of the heated cigarette, improving the smoking quality of the heated cigarette, enriching and plump the smoke, covering miscellaneous gas and wood gas and ensuring that the taste is more mellow.
In the prior art, although tea leaves are added into the heated cigarette, the tea leaves and tobacco powder are directly used for preparing the cigarette, and some heterocyclic compounds and other components can cause adverse effects on the smoke of the heated cigarette. Therefore, the development of a method for preparing the heating cigarette which can remove the bitter and astringent feeling of the tea material and retain the tea fragrance is urgently needed, so that the sensory quality of the heating cigarette is better improved.

As can be seen from the data in table 5, the heated cigarettes containing the burnt sweet tea flavor obtained by the method provided by the present invention in examples 1 to 3 not only improve the smoke concentration and smoke quality, but also enable better harmony and better lasting feeling, reduce the stimulation to the throat, improve the aftertaste of the oral cavity, and increase the sweet feeling of the oral cavity, as compared with the blank heated cigarettes.
As can be seen from examples 4 to 5, when the solvent for extracting tea leaves in step (2) was changed, the aroma of the heated cigarette was slightly insufficient; as can be seen from examples 6 to 8, when the kind of the organic solvent is changed in the step (3), the overall score of the heated cigarette is also decreased; from examples 9-11, it can be seen that the aroma of the heated cigarette is also slightly reduced when the monosaccharide is not of the type defined in the present application; in examples 12 to 13, when the mass ratio of the monosaccharide, the filtrate and the organic solvent in the step (3) is not within the range defined by the present invention, the aroma and the taste of the heated cigarette are also affected; in examples 15 to 16, when the amount of the burnt sweet tea flavor liquid added is too small, the influence on the taste of the heated cigarette is small, and when the amount of the burnt sweet tea flavor liquid added is too large, offensive odor is generated, and the performance of the heated cigarette is also influenced.
As can be seen from comparative example 1, when only the tea extract was added to the heated cigarette, the aroma of the heated cigarette was slightly rough, and the aftertaste was more pronounced; in comparative example 2, when disaccharide was used instead of monosaccharide, the caramelization reaction was poor, and further the taste of the heated cigarette was affected; in comparative example 3, when the organic solvent was replaced with water in step (3), the caramelization reaction effect was poor, and the aroma and taste of the heated cigarette were also reduced.
