Description

[0056] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0057] Figure 1 It is a structural schematic diagram of the preparation method of the composite spicy flavor reconstituted tobacco in the embodiment of the present application.

[0058] See also Figure 1A method for preparing a composite spicy flavor reconstituted tobacco leaf. The composite spicy flavor reconstituted tobacco leaf is prepared by a spice formula. The spices in the spice formula are all dry materials. The spice formula includes two types of spices, namely: a first type of spices, including star anise, cumin, cinnamon and black plum, and a second type of spices, including cloves, nutmeg, angelica, dill and lemongrass.

[0059] In the present application, the spice formula includes a variety of spices suitable for the spicy characteristics of tobacco, which can provide complex aroma levels and rich flavor characteristics. At the same time, by classifying the spices in the spice formula based on the aroma characteristics of different spices, spices with strong spicy characteristics are classified as the first type of spices, and spices with unique spicy characteristics but certain impurities are classified as the second type of spices. Combined with the preparation method of the present application, a composite spicy-flavored reconstituted tobacco with rich aroma levels can be prepared, and the undesirable impurities of the prepared reconstituted tobacco can be effectively avoided, thereby ensuring the production quality of the product.

[0060] The preparation method of the composite spicy flavor reconstituted tobacco of the present application comprises:

[0061] S100: (1) Spice Processing

[0062] The spice raw materials are weighed according to the mass ratio of the spice formula, the spice raw materials belonging to the first category of spice are powdered and loaded into the first mesh bag, and the spice raw materials belonging to the second category of spice are powdered and loaded into the second mesh bag.

[0063] In the present application, by powdering the spice raw materials, the extraction efficiency of the aroma components in the spices can be improved, so that the aroma components can be released faster and more fully.

[0064] Specifically, the formula mass ratio of the spice formula represents the mass ratio of different spices in the spice formula, specifically: star anise is 60-80%, fennel is 10-15%, cinnamon is 5-10%, black plum is 1-5%, clove is 1-5%, nutmeg is 1-5%, angelica is 1-5%, dill is 0-5%, and lemongrass is 5-15%.

[0065] In the present application, by determining the mass ratio range of different spices in the spice formula, a rich flavor layer can be formed between the various spices, the complexity of the overall aroma can be enhanced, and the aroma of a certain spice can be effectively avoided from being too prominent, thereby ensuring the balance and harmony of the overall aroma.

[0066] Specifically, the mesh size of the first type of spices after powdering is 100-1000 mesh.

[0067] In the present application, by controlling the mesh size of the first category of spices to be 100-1000 meshes, it is possible to facilitate subsequent mixing with tobacco raw materials, so that the first category of spices can be evenly distributed in the tobacco raw materials.

[0068] The first mesh bag and the second mesh bag are added to hot water at 70-90°C and boiled, and then solid-liquid separation is performed to obtain a spice extract and a first-category spice solid residue. Specifically, the solid-liquid ratio of the first mesh bag and the second mesh bag to the hot water is 1:6-1:10, and the boiling time is 30-60 minutes. After the boiling is completed, the first-category spice and the second-category spice are fished out for solid-liquid separation, and the solution obtained after boiling is the spice extract, and the first-category spice in the first mesh bag after boiling is the first-category spice solid residue.

At the same time, by controlling the mass ratio of the first type of spice solid residue added, the flavor balance of the prepared reconstituted tobacco can be controlled to ensure production quality.

[0073] The spice extract is added to the mixed raw material at a material-liquid ratio of 1:6 to 1:10, and the mixture is heated for extraction.

[0075] In the present application, by adding the spice extract to the mixed raw material for heating extraction, the aroma components in the spice extract can be fully mixed into the mixed raw material. At the same time, by controlling the solid-liquid ratio, the mixing efficiency can be guaranteed, making the flavor of the mixed raw material more intense; by controlling the cooking temperature, the destruction of the aroma components caused by excessively high temperature can be avoided; by controlling the cooking time, the aroma components can be fully mixed.

[0076] After the extraction is completed, solid-liquid separation treatment is performed to obtain a sheet base raw material and a mixed raw material extract, the sheet base raw material is pulped to prepare a sheet base, and the sheet base is placed in a constant temperature and humidity chamber for temperature and humidity balance to obtain a reconstituted tobacco sheet base;

[0123] (3) Preparation of composite spicy flavor reconstituted tobacco

[0124] The mixed raw material extract was concentrated by vacuum rotary evaporation under the following conditions: temperature 60°C, vacuum degree 40 mbar, rotation speed 45 rad / min, to obtain a density of 1.2 g / cm 3 A mixed raw material concentrate.

[0125] The mixed raw material concentrated liquid is heated to 45°C and evenly coated on the reconstructed tobacco leaf base to obtain wet reconstructed tobacco leaf base, and the wet reconstructed tobacco leaf base is baked and dried in an oven to obtain dry reconstructed tobacco leaf base, wherein the baking conditions are: temperature 110°C, time 5 minutes, and after baking and drying, it is placed in a constant temperature and humidity chamber with a relative humidity of 60% and a temperature of 22°C for equilibrium for more than 48 hours to obtain composite spicy flavor reconstructed tobacco leaves, and the coating rate is 45g / ㎡.

[0126] The evaluation results of the composite spicy flavor reconstituted tobacco leaves prepared in the above three embodiments were obtained by performing leaf rolling sensory evaluation, as shown in the following table:

[0127]

[0128] In the table, T1 represents the composite spicy flavor reconstituted tobacco leaf prepared in Example 1, T2 represents the composite spicy flavor reconstituted tobacco leaf prepared in Example 2, and T3 represents the composite spicy flavor reconstituted tobacco leaf prepared in Example 3. The evaluation results were performed in accordance with GB5606.4-2005.

[0129] The evaluation results show that the composite spicy flavor reconstituted tobacco prepared by the preparation method of the present application performs well in terms of aroma volume, strength, texture, comfort and miscellaneous smell, and the overall level of composite spicy flavor characteristics is high.

[0130] By selecting T2 reconstituted tobacco leaves with good comprehensive evaluation results, we conducted a smoking test on the blending of tobacco leaf groups, and obtained the aroma characteristic evaluation results of T2 reconstituted tobacco leaves at different blending ratios, as shown in the following table:

[0131]

[0132]

[0133] In the table, B1 indicates that the blending ratio of T2 reconstituted tobacco is 5%, B2 indicates that the blending ratio of T2 reconstituted tobacco is 8%, and B3 indicates that the blending ratio of T2 reconstituted tobacco is 12%. The evaluation results are carried out in accordance with GB5606.4-2005.

[0134] The evaluation results show that spicy and flavorful reconstituted tobacco with different blending ratios has different aroma characteristics in the tobacco leaf group. As the blending ratio increases, the aroma volume and elegance are significantly improved, which can effectively reduce foreign smells and enhance richness.

[0135] In summary, the composite spicy-flavored reconstituted tobacco prepared by the preparation method of the present application has sufficient spicy style characteristics, spicy and sweet, and the aroma volume and elegance are improved. It has good coordination with cigarettes, and the aftertaste is clean and comfortable.

[0136] The technical solution provided by this application includes the following beneficial effects:

[0137] The spice formula of the present application includes a variety of spices suitable for the spicy characteristics of tobacco, which can provide complex aroma levels and rich flavor characteristics. At the same time, by classifying the spices in the spice formula based on the aroma characteristics of different spices, and combining with the preparation method of the present application, a composite spicy-flavored reconstituted tobacco with rich aroma levels can be prepared, and the undesirable impurities in the prepared reconstituted tobacco can be effectively avoided to ensure the production quality of the product. At the same time, the present application determines the mass ratio range of different spices in the spice formula, and can effectively avoid the aroma of a certain spice being too prominent, thereby ensuring the balance and harmony of the overall aroma.

[0138] By mixing the first-class spice solid residue into tobacco raw materials, the present application can further utilize the non-volatile components in the first-class spice, effectively enhance the aroma level of the reconstituted tobacco, form a unique composite flavor, and make the spicy flavor in the prepared reconstituted tobacco more stable and lasting, avoiding the loss of flavor caused by the loss of volatile substances in the spice, and the addition of the first-class spice solid residue will not introduce bad impurities after preparation, which can ensure the product quality of the prepared reconstituted tobacco. At the same time, by controlling the mass ratio of the first-class spice solid residue added, the flavor balance of the prepared reconstituted tobacco can be controlled to ensure production quality.

[0139] The present application adds spice extract to mixed raw materials for heating extraction, so that the aroma components in the spice extract can be fully mixed into the mixed raw materials. The vacuum rotary evaporation concentration process can effectively increase the concentration of the mixed raw material extract and retain the effective aroma components for subsequent processing. The aroma components in the mixed raw material concentrate can be integrated with the reconstituted tobacco leaf base by mixing, extracting and separating the raw materials, coating, baking and temperature-humidity balance treatment, thereby further increasing the aroma and flavor of the reconstituted tobacco leaf base to obtain a composite spicy-flavored reconstituted tobacco leaf.
