Description

Technical Field

[0001] The present application relates to the technical field of papermaking process reconstituted tobacco, and in particular to a method for preparing reconstituted tobacco with the flavor characteristics of imitating cinnabar tobacco. Background Art

[0002] The tobacco made from Yunnan tobacco leaves has a delicate fragrance, no impurities, no irritation, and its gray is grayish white. The best tobacco leaves hidden in the top-grade Yunnan tobacco are "Cinnabar Tobacco". "Cinnabar Tobacco" is a tobacco leaf with cinnabar markings selected from flue-cured tobacco. Its unique cinnabar markings are produced by the accumulation of rich tobacco aromatic substances in the natural growth of tobacco leaves. Only 1-2 pieces can be selected from hundreds of high-quality tobacco leaves, so it is extremely rare. Cinnabar tobacco contains many aromatic substances and has a unique "glutinous rice fragrance". Because cinnabar tobacco is extremely rare, it cannot be used in large-scale cigarette manufacturing. It is mostly used to make water tobacco shreds, which has the characteristics of low output and great fame. "Cinnabar Tobacco" is a tobacco leaf resource that can be encountered but not sought after, and its extremely rare status fundamentally limits its large-scale application in the cigarette industry. Therefore, the innovative development of papermaking-based reconstituted tobacco with cinnabar cigarette style characteristics will play a greater role in realizing the large-scale application of "cinnabar cigarette" in the cigarette industry and promoting the high-quality development of cigarettes.

[0003] The current research will introduce glutinous rice scented leaves into reconstituted tobacco leaves, so that the prepared reconstituted tobacco leaves can emit a unique glutinous rice aroma and have an aroma style experience similar to cinnabar tobacco, thus obtaining reconstituted tobacco leaves with cinnabar tobacco style characteristics.

[0004] However, since the leaves of glutinous rice fragrant tobacco are rich in chlorophyll, which is easy to generate foreign gases when burned, the reconstituted tobacco made by the traditional reconstituted tobacco preparation method is easy to generate foreign gases after being ignited, which reduces its taste. Therefore, a reconstituted tobacco preparation method with imitating cinnabar tobacco flavor characteristics is needed to reduce the chlorophyll content in the glutinous rice fragrant tobacco, which is one of the preparation raw materials. Summary of the invention

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides a method for preparing reconstituted tobacco leaves with the flavor characteristics of imitating cinnabar cigarettes, which can remove chlorophyll and make the cinnabar cigarette glutinous rice aroma characteristics of papermaking reconstituted tobacco leaves more prominent, and when smoking, it has the aroma style experience of cinnabar cigarettes without producing impurities.

[0006] The first aspect of the present application provides a method for preparing reconstituted tobacco leaves with a flavor characteristic imitating cinnabar tobacco, comprising the following steps:

[0007] Reconstructed tobacco leaf base and water-extracted tobacco paste are prepared from cinnabar tobacco leaf raw materials;

[0008] Extracting glutinous rice fragrant leaves with 80% ethanol and acetic acid as solvents to obtain an alcohol extract, adding an oxidant to the alcohol extract for oxidation, and steaming until the alcohol extract changes from green to yellow and produces flocculent particles, filtering and concentrating to obtain a glutinous rice fragrant extract;

[0009] The water-extracted tobacco paste, the glutinous rice fragrance extract, the tobacco flavoring and the formula components are prepared according to the mass percentage to obtain a concentrated coating liquid;

[0010] A quantitative concentrated coating liquid is weighed, diluted and then applied to the reconstituted tobacco leaf base, and the reconstituted tobacco leaf with the flavor characteristics of imitation cinnabar tobacco is obtained after temperature-controlled baking and drying.

[0011] The formula components include a mixture of one or more of propylene glycol, glycerol, ethanol, water, and malic acid.

[0012] Among them, the water-extracted tobacco paste is 60-110%, the glutinous rice fragrance extract is 1-15%, the tobacco flavor is 0.1-5%, the propylene glycol is 0.5-5%, the glycerol is 0.5-5%, the malic acid is 0.05-2%, and the water is 1-10%.

[0013] The amount of acetic acid added is 1%-2% of the total amount of the solvent.

[0014] The added amount of the oxidant is 10%-20% of the total amount of the alcohol extract.

[0015] The oxidant is 1% hydrogen peroxide.

[0016] The alcohol extract is boiled and filtered, and then concentrated by vacuum distillation.

[0017] Among them, the relative density of the extract is 1.0573±0.0002.

[0018] Among them, the moisture content of reconstituted tobacco leaf samples is ≤13%.

[0019] The technical solution provided by this application may have the following beneficial effects:

[0020] The present application provides a method for preparing reconstituted tobacco leaves with the flavor characteristics of imitating cinnabar cigarettes. The papermaking reconstituted tobacco leaves prepared by the above method have outstanding glutinous rice aroma style characteristics in terms of smoking experience, are free of impurities, have a delicate and soft texture, are fresh and elegant, rich and full, mellow and mild, and better reflect the glutinous rice aroma quality characteristics of "cinnabar cigarettes", which is conducive to the large-scale application of "cinnabar cigarettes" in the cigarette industry and promotes the high-quality development of cigarettes.

[0029] Embodiment 1:

[0030] like Figure 1 The method for preparing reconstituted tobacco leaves with the flavor characteristics of imitating cinnabar tobacco comprises the following steps:

[0031] S11. Prepare reconstituted tobacco leaf base and water-extracted tobacco paste from cinnabar tobacco leaf raw materials.

[0032] With water as solvent, cinnabar tobacco leaf raw materials are mixed in a solid-liquid ratio of 1:10, and then extracted, separated, precipitated with alcohol, centrifuged and concentrated to obtain a water-extracted tobacco paste with a relative density of 1.2000±0.0002; after solid-liquid separation, the obtained tobacco solid residue is paper-made into a base material of 55g±5 / m2 by a papermaking method; the water extract is subjected to alcohol precipitation and centrifugal treatment, and the centrifuged treatment liquid is concentrated to prepare a tobacco paste with a relative density of 1.2000±0.0002.

[0033] S12. Using 80% ethanol and acetic acid as solvents to extract glutinous rice fragrant leaves to obtain an alcohol extract, adding hydrogen peroxide to the alcohol extract for oxidation, and steaming until the alcohol extract changes from green to yellow and produces flocculent particles, filtering and concentrating to obtain a glutinous rice fragrant extract.

[0034] The method uses 80% ethanol as a solvent and 1%-2% acetic acid as a solvent. The glutinous rice fragrant leaves are mixed according to a solid-liquid ratio of 1:10 and ultrasonic extraction is performed. The extraction time is 60 minutes and the temperature is room temperature. After solid-liquid separation, the solid residue is discarded. 1% hydrogen peroxide is added to the alcohol extract as an oxidant for oxidation. The amount of the oxidant added is 10%-20% of the total amount of the alcohol extract. The alcohol extract is boiled and the alcohol extract changes from green to yellow and produces flocculent particles. The boiling is continued until the extract completely turns yellow and no flocculent particles are produced. After filtering, the extract is concentrated by vacuum distillation. The alcohol extract is prepared into a glutinous rice fragrant extract with a relative density of 1.0573±0.0002.

[0035] S13, preparing the water-extracted tobacco paste, glutinous rice fragrance extract, tobacco flavoring and formula components according to mass percentage to obtain a concentrated coating solution.

[0036] The spices with obvious or auxiliary enhancement of glutinous rice aroma characteristics are evaluated and analyzed, and the spices that retain the style characteristics and meet the product requirements are prepared, by mass percentage, with 60-110% of tobacco water-extracted tobacco paste, 1-15% of glutinous rice geranium alcohol-extracted liquid, 0.1-5% of tobacco spices (one or more tobacco extracts from Zimbabwe, Brazil, the United States, Red Big, K326, etc.), 0.5-5% of propylene glycol, 0.5-5% of glycerol, 1-10% of water, and 0.05-2% of malic acid (for softening the smoke) to prepare a concentrated coating liquid that gives the reconstituted tobacco leaves the style characteristics of cinnabar tobacco.

[0037] S14, weighing a certain amount of concentrated coating liquid, diluting it and applying it on the reconstituted tobacco leaf base, and baking and drying it at a controlled temperature to obtain reconstituted tobacco leaves with the flavor characteristics of imitation cinnabar tobacco.

[0038] Quantitatively weigh 55-65% of the leaf base (dry weight) of the reconstituted tobacco leaves and 35-45% of the concentrated coating liquid (dry weight) for imparting cinnabar tobacco style characteristics to the reconstituted tobacco leaves;

[0039] After adding 1.5 times the weight of water to the weighed concentrated coating liquid, mix evenly with a heated magnetic stirrer, control the temperature at 40-60°C, and stir for 3-5 minutes.

[0040] After the coating liquid is quantitatively weighed and evenly stirred, it is completely coated on the prepared reconstituted tobacco leaf base, and then the reconstituted tobacco leaf sample is baked at a controlled temperature of 90 to 120° C. for 3 to 5 minutes. The moisture content of the reconstituted tobacco leaf sample after baking is ≤13%.

[0041] After the moisture content of the reconstituted tobacco leaf sample after baking and drying is balanced to 11-13%, the papermaking method reconstituted tobacco leaf having the characteristics of cinnabar tobacco and glutinous rice fragrance is obtained;

[0042] The prepared paper-making tobacco leaves with the characteristics of cinnabar tobacco style are moisture balanced for 48 hours, cut into shreds and rolled for smoking evaluation.

[0043] Comparative Example 1:

[0044] The difference from Example 1 is that in S2, sodium hydroxide is added to the alcohol extract as an oxidant, and other conditions remain unchanged.

[0045] A method for preparing reconstituted tobacco leaves with cinnabar tobacco-like flavor characteristics comprises the following steps:

[0046] S21. Prepare reconstituted tobacco leaf base and water-extracted tobacco paste from cinnabar tobacco leaf raw materials.

[0047] S22. Using 80% ethanol and acetic acid as solvents to extract glutinous rice fragrant leaves to obtain an alcohol extract, adding sodium hydroxide to the alcohol extract for oxidation, and steaming until the alcohol extract changes from green to yellow and produces flocculent particles, filtering and concentrating to obtain a glutinous rice fragrant extract.

[0048] S23, preparing the water-extracted tobacco paste, the glutinous rice fragrance extract, tobacco flavoring and formula components according to mass percentage to obtain a concentrated coating solution.

[0049] S24, weighing a certain amount of concentrated coating liquid, diluting it and applying it on the reconstituted tobacco leaf base, and baking and drying it at a controlled temperature to obtain reconstituted tobacco leaves with the flavor characteristics of imitation cinnabar tobacco.

[0050] Comparative Example 2:

[0051] The difference from Example 1 is that in S2, hydrogen peroxide is added to the alcohol extract for oxidation, and the glutinous rice fragrance extract is obtained after filtration and concentration, without steaming treatment, and other conditions remain unchanged.

[0052] A method for preparing reconstituted tobacco leaves with cinnabar tobacco-like flavor characteristics comprises the following steps:

[0053] S31. Prepare reconstituted tobacco leaf base and water-extracted tobacco paste from cinnabar tobacco leaf raw materials.

[0060]

[0061] The difference between Comparative Example 1 and Example 1 is the addition of different oxidants. The low-concentration hydrogen peroxide added in Example 1 will be completely converted and decomposed into water and oxygen and dissipated if the cooking time is sufficient; while the sodium hydroxide added in Comparative Example 1 can partially neutralize with the acid and oxidatively modify the chlorophyll, but a part of it may still remain in the alcohol extract and affect the final sensory evaluation. Therefore, the reconstituted tobacco obtained by the steps of Example 1 has obvious glutinous rice fragrance characteristics, small impurities and small stimulation, and a clean and comfortable aftertaste; while the reconstituted tobacco obtained by the steps of Comparative Example 1 has glutinous rice fragrance characteristics, but the aroma is spicy and prickly, with a slight alkaline prick, impurities, unnatural harmony, and a clean aftertaste.

[0062] The difference between Comparative Example 2 and Example 1 lies in the cooking process. In Example 1, the chlorophyll introduced into the glutinous rice leaves is removed by the cooking step, and the excess hydrogen peroxide is boiled and decomposed into water and oxygen for dissipation. During the process, the chlorophyll is damaged and degraded by high temperature, so that it forms flocculent particles from dissolution and precipitation, thereby achieving the effect of removing chlorophyll; while in Comparative Example 2, the cooking step is lacking, which makes the chlorophyll content of the reconstructed tobacco leaves generated by Comparative Example 2 higher than that of Comparative Example 1, and the effect of reducing impurities cannot be achieved. Therefore, although the reconstructed tobacco leaves obtained by the steps of Comparative Example 2 have the characteristics of glutinous rice fragrance, they have obvious alkaline thorns, green and mixed flavors, high smoke concentration, mixed, obvious impurities, obvious stimulation, unnatural harmony, and astringent and residual aftertaste.
