Description

Technical Field

[0001] The present invention relates to the technical field of tobacco flavorings, and particularly relates to a tobacco flavoring for highlighting the sweet flavor characteristics of Chinese-style cigarettes, a preparation method and an application thereof. Background Art

[0002] The unique "sweet" flavor characteristic of Chinese-style cigarettes is one of the important signs that distinguish them from American, British, Japanese and other cigarettes. In order to highlight this characteristic, substances such as sugars, extracts and Maillard reaction products are usually used in the flavoring of Chinese-style cigarettes; the reason why these substances can make the smoke produce a sweet flavor is mainly because they contain or crack to produce volatile sweet substances such as ketones and dehydrated sugars. However, since the content of sweet substances transferred to the smoke is extremely low, the effect of highlighting the "sweet" flavor characteristic of cigarettes is not good. Therefore, blending a tobacco flavoring containing volatile sweet substances and adding it to cigarettes can significantly increase the content of sweet substances in the smoke and effectively highlight the "sweet" flavor characteristic of Chinese-style cigarettes.

[0003] The threshold of the sweetening effect of a spice on cigarettes refers to the concentration range at which the sweet taste can be felt when the spice is added to cigarettes and smoked. The minimum value is the lowest concentration value of the sweetness of the perceivable compound, and the maximum value is such that when the concentration exceeds this value, the intensity difference of the sweetness stimulation cannot be distinguished by the senses or other discomfort will occur.

[0004] Therefore, the present invention first starts from the perspective of the threshold of the sweetening effect of cigarettes, conducts the blending of sweet tobacco flavorings, and obtains a tobacco flavoring with excellent sweetening performance. It not only eliminates the adverse components that produce negative effects such as bitterness, spiciness and cloyingness in traditional flavorings, but also blends a tobacco flavoring containing volatile sweet substances and adds it to cigarettes, which can significantly increase the content of sweet substances in the smoke and effectively highlight the sweet flavor characteristic of Chinese-style cigarettes. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a tobacco flavoring for highlighting the sweet flavor characteristic of Chinese-style cigarettes, a preparation method and an application thereof, which can effectively increase the content of sweet substances in the smoke and highlight the sweet flavor characteristic of Chinese-style cigarettes.

[0006] The technical problem to be solved by the present invention is realized through the following technical solutions:

[0007] A tobacco flavoring for highlighting the sweet flavor characteristic of Chinese-style cigarettes, the tobacco flavoring comprising: a ketone sweet base, a sugar auxiliary base and a solvent. Among them, based on 100%, the weight ratio of the ketone sweet base and the sugar auxiliary base is shown in Table 1 below:

[0008] Table 1

[0009]

[0010] The balance is the solvent.

[0011] Preferably, the solvent is propylene glycol, water, or a mixture of propylene glycol and water in any proportion.

[0012] A method for preparing a tobacco flavor that highlights the sweet flavor characteristics of Chinese-style cigarettes. According to the sweet flavor action threshold of compounds in cigarettes, a ketone sweet base and a sugar auxiliary base are prepared, and the specific steps are as follows:

[0013] (1) Evaluation and screening of ketone and sugar sweet compounds

[0014] By analyzing the components of common tobacco extracts, 10 ketone compounds with a mass content greater than 0.2 mg / kg and 6 sugar compounds with a mass content greater than 5 mg / kg are selected. Compounds with different concentration gradients are added to cigarettes for smoking, and their sweet flavor action thresholds in cigarettes are measured respectively. See Table 2 below for details:

[0015] Table 2 Measurement of the sweet flavor action threshold of compounds in cigarettes

[0016]

[0017] (2) Preparation of sweet tobacco flavor

[0018] In the preparation of the ketone sweet base, acetophenone, p-methylacetophenone, β-ionone, and α-ionone with relatively high sweet flavor action thresholds in cigarettes are removed; in the preparation of the sugar auxiliary base, xylose, arabinose, sucrose, and maltose with relatively high sweet flavor action thresholds in cigarettes are removed; and the dosage is adjusted up and down in proportion based on the content of each sweet component to optimize the formula, and finally the solvent is added to make up to 100%.

[0019] An application of a tobacco flavor in cigarettes.

[0020] Preferably, the addition amount of the tobacco flavor is 0.4-1.0% of the mass of the tobacco shreds.

[0021] The above technical solutions of the present invention have the following beneficial effects:

[0022] The present invention first utilizes the sweet flavor action threshold of spices in cigarettes to develop a tobacco flavor that highlights the sweet flavor characteristics of Chinese-style cigarettes. Adding the tobacco flavor of the present invention to cigarettes, the sensory evaluation results show that: compared with the blank cigarettes without adding the tobacco flavor of the present invention, the sweet and moist feeling in the mouth of the cigarette samples after addition is significantly increased, highlighting the sweet flavor characteristics of Chinese-style cigarettes and having potential application value.
