Description

Technical Field

[0001] The invention relates to the technical field of flavors, in particular to a tobacco flavor. Background Art

[0002] The chemical substances in cigarettes are mainly dry tobacco. During the chemical treatment process, it is inevitable to add many ingredients for different purposes, such as flavors. Flavors can impart fragrance and cover up the bad smell and irritating taste produced when cigarettes burn. When a cigarette is lit, the temperature is extremely high, and it is easy to pre-bake the unburned area near the combustion, causing the flavor to volatilize in advance due to the high temperature. When the pre-baked area is burned, the loss of flavor will cause the fragrance to weaken and the irritation to be obvious, affecting the user's sensory experience. Therefore, under normal circumstances, manufacturers will slightly increase the amount of flavors used to ensure the user's sensory experience, which increases production costs.

[0003] Therefore, it is promising to develop a flavor that can withstand high temperature and release slowly to improve the user's sensory experience. Summary of the invention

[0004] The object of the present invention is to provide a tobacco flavor containing a plant extract and a preparation method thereof, so as to solve the problem that the tobacco flavor is easily affected by high temperature and volatilizes prematurely, affecting the sensory experience of users.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A tobacco flavor containing plant extracts, comprising: 1-6 parts of chitosan, 0.5-1 parts of xanthan gum, 0.5-4 parts of gelatin, 0.4-5 parts of cellulose acetate phthalate, 0.2-0.5 parts of gum arabic, 0.3-1.5 parts of plant extracts and 0.3-3 parts of flavors.

[0007] Furthermore, the ingredients include: 2 parts of chitosan, 0.8 parts of xanthan gum, 3 parts of gelatin, 2 parts of cellulose acetate phthalate, 0.5 parts of gum arabic, 0.5 parts of plant extract, and 0.8 parts of flavor.

[0008] Furthermore, the sum of the amounts of chitosan, xanthan gum, gelatin, and cellulose acetate phthalate: the sum of the amounts of gum arabic, plant extracts, and flavors is 3:1.

[0009] Furthermore, the plant extracts include peppermint extract, patchouli oil, grape seed extract, and hop extract.

[0010] The present invention also provides a method for preparing a tobacco flavor containing a plant extract, the steps comprising:

[0011] (1) Weigh each raw material according to the formula;

[0012] (2) preparing a 3.5% to 4% gum arabic solution, then adding plant extracts and essences, emulsifying and homogenizing, and vacuum freeze-drying and crushing to obtain a powdery solid as the core material;

[0013] (3) dissolving chitosan, xanthan gum, gelatin, and cellulose acetate phthalate in water at a ratio of the sum of the four amounts: water = 1:2-1:2.5 to obtain a wall material solution;

[0014] (4) adding the core material into the wall material solution, stirring evenly, and spray drying to form microcapsules containing plant extracts and flavors, namely, tobacco flavors containing plant extracts.

[0015] Furthermore, the temperature of the emulsification and homogenization in step (2) is 45-50°C.

[0016] Furthermore, the vacuum freeze-drying process is: vacuum freeze-drying at -70 to -65°C and a vacuum degree of 2 to 6 Pa.

[0017] Furthermore, in step (4), the air inlet temperature of the spray drying is 100-120°C, and the air outlet temperature is 70-80°C.

[0018] The present invention also provides use of the tobacco flavor containing the plant extract prepared by the method in preparing cigarettes.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The flavors and plant extracts are wrapped in microcapsules. Although the area near the burning point of the cigarette is baked at high temperature, the flavors and plant extracts will not evaporate prematurely due to the wall material, reducing losses. Each burning area maintains the required amount of flavors and plant extracts to ensure the user's sensory experience.

[0021] Grape seed extract is a type of polyphenolic substance extracted and separated from grape seeds, mainly composed of polyphenolic substances such as proanthocyanidins, catechins, epicatechin, gallic acid, epicatechin gallate, etc. Among them, proanthocyanidins have extremely strong activity and can inhibit carcinogens in cigarettes.

[0022] Peppermint extract can impart a cooling taste and oral temperature.

[0023] Patchouli oil can enhance the richness of the fragrance. DETAILED DESCRIPTION
