Description

Technical Field

[0001] The invention belongs to the technical field of tobacco flavors, and particularly relates to a magnolia flower water-soluble flavor and application thereof. Background Art

[0002] Magnolia, also known as Magnolia, Purple Magnolia, is the dried flower buds of Magnolia officinalis or Magnolia wudangensis, belonging to the Magnoliaceae family. Magnolia is a multi-source Chinese medicinal material. In my country, the cultivation of Magnolia has a history of more than 2,000 years. It is recorded in ancient books such as "Compendium of Materia Medica", "Compendium of Materia Medica Yanyi" and "Yang Xiong Ganquan Fu". Magnolia has the effect of dispersing wind and cold and clearing the nasal passages. Modern medical research shows that the Chinese medicine Magnolia plays an important pharmacological role in the treatment of various diseases, and is used to treat various rhinitis such as allergic rhinitis and sinusitis. The main components of magnolia are volatile substances, alkaloids, lignans, phenolic acid compounds, etc. Among them, volatile substances are its main biologically active components, and the composition is complex, including hydrocarbons, ketones, alcohols, esters, aldehydes, acids, phenols, ethers and other compounds, and have a special aroma. Lignans are the main components of magnolia extracts that exert pharmacological activity, and have multiple pharmacological effects such as anti-allergic, anti-inflammatory, antibacterial, and antiviral. Eucalyptol, as the main active ingredient in the volatile components of magnolia flowers, plays an important role in aroma. Its eucalyptus aroma is the main aroma component of magnolia flower extracts. Pinene has good anti-inflammatory and anti-allergic effects. The volatile oil of magnolia has a fresh smell, so it can also be used as an important fragrance raw material and is widely used in the cosmetics and cigarette industries.

[0003] The overall aroma of magnolia flower extract is relatively heavy, with a strong medicinal aroma, which will cover the original aroma of cigarette tobacco to a certain extent. In addition, the medicinal aroma in the extract is obvious when smoking, which affects the taste of smoking. Therefore, its application in the field of tobacco flavors and fragrances is limited. Summary of the invention

[0004] The inventors found that the use of magnolia flower extract alone as tobacco flavor has many technical defects. The first is the irrationality of the aroma structure, which is mainly manifested in the fact that the strong characteristic components such as eucalyptol, eucalyptol, α-pinene alcohol in the extract make the aroma too strong. The single aroma characteristics such as the thorny eucalyptus smell, camphor smell and spicy taste brought by these components are too prominent. At the same time, the aroma lacks the necessary layering, and the overall aroma presents a heavy medicinal aroma, which affects the sensory quality of the product.

[0005] Secondly, the compatibility of magnolia flower extract with tobacco base is poor. Its strong characteristic aroma will cover up the inherent aroma characteristics of tobacco, the aroma fusion is not enough and the harmony is poor, making it difficult to form a coordinated and stable composite aroma effect. This compatibility problem seriously restricts the application of magnolia flower extract in tobacco flavors.

[0006] In addition, the sensory experience during actual use is also obviously insufficient. Specifically, the release of the medicinal aroma is too prominent during the inhalation process, the aroma is poorly persistent, and a long-lasting and stable aroma effect cannot be formed, resulting in insufficient taste comfort, which ultimately affects the overall quality of the product.

[0007] In response to the above technical problems, the present invention systematically studies the aroma characteristics of magnolia flower extract and innovatively designs a multi-component synergistic composite flavor formula. The design objectives of this formula mainly include three aspects: first, optimizing the aroma structure so that the characteristic aroma of magnolia flower can be reasonably displayed; second, improving the coordination with the tobacco base material to achieve a harmonious fusion of aroma; third, improving the sensory experience during the smoking process and improving product quality. Through this innovative technical solution, the key technical problems of the application of magnolia flower extract in tobacco flavors have been successfully solved.

[0008] The first aspect of the present invention provides a water-soluble magnolia flower essence, which includes a main fragrance, a blending agent, a modifier, a fixative and a solvent, wherein the main fragrance is selected from one or more of magnolia flower extract, acacia acetone, eucalyptol, α-terpineol, terpinene, caryophyllene and pinene, and the content thereof is 3 to 15 parts by weight; The fragrance agent is selected from one or more of linalool, p-methoxyacetophenone, 3,4-dimethoxyphenol, citronellol, geraniol, limonene, 5-hydroxymethylfurfural, water anise terpene, methyl acetate, sesquiterpene and β-myrcene, and its content is 1.5 to 3 parts by weight; The modifier is selected from one or more of benzyl alcohol, paeonol, phenylethyl alcohol, pyrone and phenol, and its content is 0.5 to 1.5 parts by weight; The fixative is selected from one or more of vanillin and ethyl vanillin, and its content is 0.2 to 0.5 parts by weight; The solvent is selected from one or more of 95% ethanol and propylene glycol, and its content is 80-95 parts by weight; The magnolia flower extract is a magnolia flower extract pretreated with a 50% ethanol solution, and the treatment method is: taking the magnolia flower extract, adding a 50% ethanol solution to dissolve it, and filtering it with a microporous filter membrane to obtain the pretreated magnolia flower extract.

[0009] Furthermore, the above-mentioned magnolia flower water-soluble essence includes any one or more of the following a) to e): a) The main fragrance agent is present in an amount of 10 to 14 parts by weight; b) the fragrance blending agent, in an amount of 3 to 4 parts by weight; c) the modifier, in an amount of 0.75 to 1 part by weight; d) the fixative, in an amount of 0.2 to 0.4 parts by weight; e) The solvent is present in an amount of 80 to 90 parts by weight.

[0010] Furthermore, the water-soluble magnolia flower essence of the present invention contains the following ingredients, in parts by weight: 5-15 parts of magnolia flower extract, 2-3 parts of acacia acetone, 0.15-0.25 parts of eucalyptol, 0.15-0.25 parts of α-terpineol, 0.25-0.35 parts of terpinene, 0.15-0.25 parts of caryophyllene, 0.15-0.25 parts of pinene, 0.5-1.5 parts of linalool, 0.15-0.25 parts of p-methoxyacetophenone, 0.15-0.25 parts of 3,4-dimethoxyphenol, and 0.15-0.25 parts of citronellol. 0.25-0.35 parts of geraniol, 0.15-0.25 parts of limonene, 0.15-0.25 parts of 5-hydroxymethylfurfural, 0.15-0.25 parts of water anise terpene, 0.15-0.25 parts of methyl acetate, 0.1-1 parts of sesquiterpene, 0.1-0.2 parts of β-myrcene, 0.15-0.25 parts of benzyl alcohol, 0.15-0.25 parts of paeonol, 0.1-0.2 parts of phenylethyl alcohol, 0.15-0.25 parts of pyrone, 0.15-0.25 parts of phenol, 0.25-0.35 parts of ethyl vanillin, and 80-85 parts of solvent.

[0011] Further, the water-soluble essence of magnolia flower of the present invention contains the following ingredients, in parts by weight, 10 parts of magnolia flower extract, 2.5 parts of acacia acetone, 0.2 parts of eucalyptol, 0.2 parts of α-terpineol, 0.3 parts of terpinene, 0.2 parts of caryophyllene, 0.2 parts of pinene, 1 part of linalool, 0.2 parts of p-methoxyacetophenone, 0.2 parts of 3,4-dimethoxyphenol, 0.2 parts of citronellol, 0.3 parts of geraniol, 0.2 parts of limonene, 0.2 parts of 5-hydroxymethylfurfural, 0.2 parts of water anise terpene, 0.2 parts of methyl acetate, 0.5 parts of sesquiterpene, 0.15 parts of β-myrcene, 0.2 parts of benzyl alcohol, 0.2 parts of paeonol, 0.15 parts of phenylethyl alcohol, 0.2 parts of pyrone, 0.2 parts of phenol, 0.3 parts of ethyl vanillin, and 80 to 85 parts of solvent.

[0012] Furthermore, the solvent is a combination of 95% ethanol and propylene glycol, and the weight ratio of 95% ethanol to propylene glycol is (1.5-3):1.

[0013] Furthermore, the weight ratio of 95% ethanol to propylene glycol is 2.75:1.

[0014] The water-soluble magnolia flower essence of the present invention can be used as a cigarette additive, especially as a cigarette filter flavor. The flavor is added in the following manner: take the water-soluble magnolia flower essence, dilute it with 75% ethanol, and add it to the cigarette filter, wherein the water-soluble magnolia flower essence is weighed in an amount of 0.1-1% of the weight of the cigarette.

[0015] The second aspect of the present invention provides a method for preparing the above-mentioned magnolia flower water-soluble flavor, comprising: adding a main fragrance, a blending agent, a modifier and a fixative into a solvent and mixing them evenly.

[0016] The third aspect of the present invention provides use of the water-soluble magnolia flower essence in cigarettes, preferably as a cigarette additive, and particularly preferably as a cigarette flavoring.

[0017] The water-soluble essence of magnolia flower can be used for tobacco shreds, sheets, cigarette lining paper, cigarette filters and the like.

[0018] A fourth aspect of the present invention provides a cigarette comprising the above-mentioned magnolia flower water-soluble flavor of the present invention.

[0019] The present invention has shown through a large number of experimental studies that the use of magnolia flower extract alone as tobacco flavor has the following main problems: From the evaluation results of the control group (10#), it can be seen that the total score of the formula with only magnolia flower extract added in the sensory evaluation is only 82.95 points, which is significantly lower than the preferred formula of the present invention. In particular, in terms of aroma characteristics, the scores of eucalyptus, woody and floral characteristics are all 2.0 points, indicating that it is difficult to form an ideal aroma effect by using magnolia flower extract alone.

[0020] Specifically, there are three main technical obstacles in the application of magnolia flower extract in tobacco flavors: First, from the perspective of aroma structure, the extract itself has a relatively heavy aroma and a heavy medicinal aroma. This is verified by the results of GC-O analysis, in which eucalyptol contributes to the thorny eucalyptus leaf gas and camphor flavor (aroma intensity 4 points), eucalyptol brings a strong eucalyptus leaf flavor (aroma intensity 5 points), and α-pineneol produces lilac, camphor and spicy flavors (aroma intensity 4 points). The superposition of these strong characteristic aromas results in an overly strong and single aroma. Second, in terms of coordination with tobacco base materials, the use of magnolia flower extract alone will have a significant covering effect on the original tobacco flavor. This can be confirmed by the fact that the harmony score of the 10# formula (4.34 points) is significantly lower than that of the preferred formula (4.73 points). Third, in terms of actual application effects, the medicinal aroma in the extract is prominent during the smoking process, which is reflected in the lower aftertaste score (20.51 points) and poor sensory comfort of the 10# formula.

[0021] In contrast, the preferred formula of the present invention successfully solves the above problems through a carefully designed composite flavor system. First, through the synergistic effect of the flavoring agent, linalool (especially when its content is 0.5-1.5 parts) provides an ethereal feeling and reduces the dullness of the aroma, p-methoxyacetophenone (especially when its content is 0.15-0.25 parts) adds fruity and hawthorn aromas, and 3,4-dimethoxyphenol (especially when its content is 0.15-0.25 parts) supplements the woody and sweet flavors, significantly improving the aroma structure, and increasing the scores of eucalyptus, woody and floral characteristics to 3.8, 3.6 and 3.9 points respectively. Secondly, through the regulation of the modifier, benzyl alcohol (especially when its content is 0.15-0.25 parts) coordinates the floral aroma and softens the heavy floral aroma. Paeonol (especially when its content is 0.15-0.25 parts) brings a cool feeling and reduces the smoking temperature of cigarettes. Pyrone (especially when its content is 0.15-0.25 parts) adds a sweet taste and achieves a good fusion with the tobacco aroma. Finally, through the aroma fixing effect of ethyl vanillin (especially when its content is 0.25-0.35 parts), the balance of aroma release is ensured, and the aftertaste score is increased to 21.62 points, which significantly improves the sensory experience during the smoking process.

[0022] The experimental data fully proves that the present invention not only overcomes the various defects of magnolia flower extract when used alone, but also achieves an overall improvement in aroma quality through innovative formula design. The selection and proportion of each component are precisely designed to jointly construct a rich, coordinated and stable aroma system. In particular, the excellent performance shown in cigarette applications provides important technical support for the promotion and application of magnolia flower in the field of tobacco flavors.

[0023] The beneficial effects of the present invention are as follows: 1. The technical solution of the present invention solves the problem that the magnolia flower extract covers the tobacco aroma and the medicinal aroma is obvious during smoking, which affects the taste of smoking by combining magnolia flower extract with chemical components. The obtained magnolia flower-flavored tobacco flavor has stable quality, delicate and transparent smoke, and is comfortable in the mouth without residue. This formula is promoted to cigarettes with excellent effects.

[0024] 2. The sensory evaluation results show that the water-soluble essence of magnolia flower provided by the present invention has a more prominent fragrance and a more lasting and stable fragrance. After the water-soluble essence of magnolia flower of the present invention is added to cigarettes, the fragrance characteristics of magnolia flower are given to the cigarettes, the fragrance of the cigarettes is significantly increased, and the smoking quality and sensory comfort of the cigarettes are significantly improved. DETAILED DESCRIPTION

[0025] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0026] Those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. Specific conditions are not specified in the examples, and the conditions are carried out according to conventional conditions or conditions recommended by the manufacturer. The components used without indicating the manufacturer are all conventional products available commercially. The magnolia flower extract and the spices involved in the examples were purchased from Guangzhou Lianfeng Spice Technology Co., Ltd.

[0027] As mentioned above, the overall aroma of magnolia flower extract is relatively heavy, and the medicinal aroma is heavy, which will cover the original aroma of cigarette tobacco to a certain extent, and the medicinal aroma in the extract is obvious when smoking, which affects the taste of smoking, thus limiting its application in the field of tobacco flavors and fragrances. Based on this, the present invention provides a magnolia flower water-soluble flavor.

[0028] Among them, the design ideas of the formula of magnolia flower water-soluble flavor are as follows: 1. Selection of fragrance raw materials Principles for selecting spices: (1) They must comply with national food additive requirements such as GB2760, YQ-52, and YQ-53; (2) They must be well soluble in solvents and not cause negative chemical reactions; (3) They must be widely available and reasonably priced.

[0029] According to the different components of the water-soluble flavor of magnolia flower, combined with the composition characteristics of magnolia flower extract, the main components can be divided into four types: main fragrance, combination fragrance, modifier, and fixative. The main fragrance of the water-soluble flavor of magnolia flower described in the present invention is magnolia flower extract, but due to the limitations of factors such as the fragrance intensity, density, and diversity of fragrance of the extract, it cannot be completely used as the main fragrance of the water-soluble flavor of magnolia flower, and needs to be coordinated with other main fragrances. According to the GC-MS detection and analysis results and the analysis of the component characteristics, combined with the sensory analysis results of the magnolia flower extract, acacia acetone, eucalyptol, α-pinene, caryophyllene, eucalyptol, pinene, etc. are selected as the main fragrance of the water-soluble flavor of magnolia flower.

[0030] Fragrance blending agents play a coordinating role in the process of flavor preparation. In order to highlight the aroma style of magnolia flower water-soluble flavor and reduce the influence of the medicinal aroma of magnolia flower extract on the overall aroma of the flavor, linalool, p-methoxyacetophenone, 3,4-dimethoxyphenol, etc. were selected according to the sensory evaluation results of the extract. Linalool itself helps to enhance the ethereal feeling of the aroma and reduce the dullness of the aroma. The appropriate addition of p-methoxyacetophenone and 3,4-dimethoxyphenol can enrich the different aromas of the flavor, such as fruity, woody, and sweet, making the aroma of the flavor fuller and more coordinated.

[0031] Modifiers are also called modifiers. Their fragrance is different from that of the main fragrance. They are subtle fragrance ingredients that can be effective with a small amount. Their function is to change the style of the fragrance and make it unique. Benzyl alcohol, paeonol, pyrone, and phenol are selected as modifiers. Benzyl alcohol helps to coordinate the floral aroma of magnolia flower extract, making the heavy floral aroma softer and richer; paeonol makes the fragrance feel cool as a whole, helps to reduce the smoking temperature of cigarettes and has a refreshing effect; pyrone can increase the sweet taste of the fragrance.

[0032] Fixatives help to prolong the volatilization time of the flavor, make the various flavor components in the flavor evaporate evenly, prevent the rapid volatilization of volatile flavors, keep the fragrance of the flavor unchanged during application, and make the flavor have a certain degree of durability. Vanillin, ethyl vanillin, etc. are selected.

[0033] 2. Design of formula of water-soluble essence of magnolia flower According to the analysis results and sensory evaluation results of the functional extract of magnolia flower, the aroma characteristics of the water-soluble flavor are enriched based on the extract, and the overall aroma intensity is enhanced by adding appropriate proportions of acaciaacetone, eucalyptol, α-pinene, caryophyllene, eucalyptol, pinene, etc.; secondly, different types and proportions of blending agents are prepared, such as: fruity scent, woody scent, etc., to coordinate the aroma of the extract and the main aroma components; followed by modification to enhance the style of the water-soluble flavor of magnolia flower; finally, the fixative is added, and the amount is controlled within 0.3%.

[0034] From the perspective of formula structure, the preparation of magnolia flower water-soluble flavor can be divided into three interrelated components: top note, body note and base note, which can also be regarded as three interconnected levels of flavor aroma. All the spices used in these three components or levels and their proportions form the overall formula of the flavor. The preparation of the magnolia flower water-soluble flavor of the present invention adopts a layered, step-by-step trial preparation and evaluation method. In the first stage of formula formulation, the main formula of the flavor is preliminarily determined, usually by comparative analysis and trial and error method. In the second stage, the aroma is modified according to the results of the flavor preparation, the hierarchical structure of the flavor is enriched, and the overall coordination of the magnolia flower water-soluble flavor is improved. In the third stage, the preliminary formula is repeatedly scrutinized, evaluated, and placed to observe its fragrance retention and fragrance quality, and a suitable fixative is used according to the actual perfume preparation. Specifically, it includes the following steps: The first step is to obtain the ratio of the main aroma components of the water-soluble essence of magnolia flower through trial matching. A higher concentration of magnolia flower extract will make the overall fragrance of the essence heavier, the medicinal smell is heavier, and it is more difficult to modify and change the tone. A lower concentration of magnolia flower extract makes the concentration of the modifier higher, which weakens the weight of the extract in the entire formula system. Comparing the overall aroma quality of magnolia flower functional extracts of different concentrations, the magnolia flower extract content dissolved in 50%~70% solvent is compared. After dissolution, the aroma is transparent and light, and the aroma intensity and fragrance applicability are good. The second step is to use magnolia flower extract as the main aroma component, modify the aroma of the dissolved magnolia flower water-soluble essence, add the main fragrance, fragrance agent, and fragrance fixer to modify and trial match, and finally obtain the preliminary overall formula of the essence. When trying to match the body fragrance part, starting from the main ingredients such as acacia acetone and α-pinene alcohol, find the most suitable ratio, and then gradually add other component fragrance varieties to obtain a preliminary formula. The formula sheet includes spices or auxiliary materials for coordination, modification and scent setting. After small-scale trial mixing, evaluation, formula modification, re-trial mixing and re-evaluation, the preliminary overall formula of the fragrance is determined.

[0035] The embodiments of the present invention will be described in detail below in conjunction with the examples, but those skilled in the art will appreciate that the following examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. Where specific conditions are not specified in the examples, they are carried out under conventional conditions or conditions recommended by the manufacturer. Where the components used are not specified by the manufacturer, they are all conventional products that can be obtained commercially.

[0036] Example 1: Analysis of ingredients in Magnolia flower extract 1. Determination of dilution scheme of magnolia flower extract A dissolution test was performed using a certain concentration of ethanol, propylene glycol, or a mixed solution of propylene glycol and ethanol until the mixed solution was uniform. The magnolia flower extract was filtered for solids using a microporous filter membrane, and then the viscosity, relative density and refractive index of the magnolia flower extract were tested using a viscometer, a density meter and an Abbe refractometer.

[0037] Because different concentrations of ethanol solutions have different effects on aroma, too high a concentration of ethanol solvent will damage the aroma of magnolia flower water-soluble essence and reduce the intensity of the aroma when it is smelled. Too low a concentration of ethanol solvent will make it difficult to completely dilute the extract, resulting in a small amount of magnolia flower extract residue or trace precipitation. Four different concentrations of ethanol solutions, 90%, 70%, 50%, and 25%, were selected as the main solvents to dissolve the magnolia flower extract. The aroma characteristics and dissolution results of magnolia flowers in different concentrations of solvents are shown in the following table.

[0038] Table 1 Aroma characteristics of magnolia flowers in different solvent concentrations

[0039] Note: The aroma intensity scores in the table are: 0-none, 1-very weak, 2-weak, 3-medium, 4-strong, 5-very strong; Dissolution: The sample was left to stand at 25°C for 24 hours and then observed: Completely dissolved: The solution is clear, with no visible precipitation; Trace solids: The solution is basically clear, with a small amount of precipitation visible at the bottom of the bottle; Small amounts of solids: The solution is slightly turbid, with an obvious precipitation layer at the bottom of the bottle; Large amounts of solids: The solution is turbid, with a large amount of precipitation.

[0040] As can be seen from Table 1, the results obtained by diluting the magnolia flower extract with different concentrations of ethanol solution are different. The sensory evaluation personnel conducted olfactory evaluation on the four samples one by one. Among them, the magnolia flower extract dissolved in 50% and 70% ethanol solution has obvious eucalyptus, sweet, floral and herbal aroma, which is the most similar to the original aroma of magnolia flower, and the magnolia flower extract can be completely dissolved. The 90% ethanol solution significantly affects the aroma intensity and aroma texture of the magnolia flower extract, making the magnolia flower extract solution present a weak herbal and green smell, but the dilution is more thorough. The magnolia flower extract dissolved in 30% ethanol solution presents a certain woody and fruity aroma, a small amount of solids cannot be dissolved, and there is precipitation in the bottle after standing.

[0041] The above-mentioned ethanol solutions with concentration gradients were subdivided. Since the 30% ethanol solution failed to fully dissolve the extract, it can be seen from the comparison of the dissolution of the 70% and 50% ethanol solutions in the above table that the dissolution effect of ethanol solutions with a concentration of more than 70% is worse than that of ethanol solutions with a concentration of less than 70%. Therefore, this comparative experiment selected ethanol solutions with a concentration gradient between 35% and 65%. The specific comparison results are shown in the following table: Table 2 Aroma characteristics of magnolia flowers in different solvent concentrations

[0042] Note: The aroma intensity scores in the table are: 0-none, 1-very weak, 2-weak, 3-medium, 4-strong, 5-very strong; Dissolution: The sample was left to stand at 25°C for 24 hours and then observed: Completely dissolved: The solution is clear, with no visible precipitation; Trace solids: The solution is basically clear, with a small amount of precipitation visible at the bottom of the bottle; Small amounts of solids: The solution is slightly turbid, with an obvious precipitation layer at the bottom of the bottle; Large amounts of solids: The solution is turbid, with a large amount of precipitation.

[0043] From the dissolution results of the above 7 groups of ethanol solutions with different concentrations, it can be seen that the aroma characteristics of the magnolia flower extract dissolved in 45%-60% ethanol solution are obvious, with obvious eucalyptus, woody and floral aromas, but the dissolution effect of the solvent with a lower concentration is not ideal, with more solid precipitation and the aroma is too dull and heavy. After comprehensive comparison, 50% ethanol solution was selected as the main dilution solution of magnolia flower extract for water-soluble flavor component analysis.

[0044] 2. Test conditions and methods Gas chromatography conditions: Agilent chromatographic column 19091S-433 (30 m×250 μm, 0.25 μm) capillary column; flow rate 1.0 mL / min, initial column temperature 40°C, maintained for 2 min, then increased to 250°C at 3°C / min, maintained for 40 min and ended.

[0045] Mass spectrometry conditions: EI ionization mode; ion source temperature 230 °C, quadrupole temperature 150 °C; acquisition mode full scan, mass scan range 50.00-550 u; solvent delay 0.00.

[0046] 3. Data Analysis The GC-MS analysis of the magnolia flower extract dissolved in 50% ethanol solution was performed. The main components detected by GC-MS analysis of the magnolia flower extract are shown in Table 3.

[0047] Table 3 Main components detected by GC-MS in Magnolia flower extract

[0048] Note: The compounds and corresponding contents in the table are displayed for the main compounds.

[0049] As can be seen from Table 3, the aroma chemical components of magnolia flower extract include alkenes, alcohols, etc. The alcohols include farnesol, citronellol, geraniol, etc., and the alkenes include pinene, caryophyllene, β-myrcene, etc.

[0050] 4. Gas chromatography-olfaction (GC-O) On the basis of determining the volatile substances of magnolia flower, the components of magnolia flower extract were identified and distinguished by gas chromatography-olfaction (GC-O) detection. The olfaction instrument model is sniffer9000 GCO.

[0051] Table 4 Identification and differentiation of main aroma components of Magnolia flower extract

[0052] Note: The aroma intensity scores in the table are: 0-none, 1-very weak, 2-weak, 3-medium, 4-strong, 5-very strong.

[0053] From the olfactory results, it can be seen that the functional extract of magnolia flower is mainly composed of eucalyptus, floral and woody notes, supplemented by sweet, medicinal and plant notes. Eucalyptol, eucalyptol, α-pinene alcohol and phenol in magnolia flower extract contribute the most to the main style characteristics of the aroma, and other components serve as auxiliary aroma characteristics. Benzyl alcohol and caryophyllene are the main sources of the floral aroma of magnolia extract; farnesol, pyrone and 3,4-dimethoxyphenol are one of the key components for increasing the sweet and refreshing aroma of the essence; eucalyptol, β-myrcene, α-pinene alcohol and eucalyptol are the main sources of eucalyptus and woody notes in the extract.

[0054] Embodiment 2: Optimization of formula of water-soluble essence of magnolia flower First, the magnolia flower extract is pretreated, specifically: taking the magnolia flower extract, adding 50% ethanol solution to dissolve it, filtering it with a microporous filter membrane (0.22μm), and then using a viscometer, a density meter and an Abbe refractometer to detect the viscosity, relative density and refractive index of the magnolia flower extract to reach 14±1mpas, 1.047±0.01d, and 1.4±0.01n, respectively, to obtain the pretreated magnolia flower extract. As mentioned above, the pretreated magnolia flower extract contains at least farnesol, eucalyptol, methyl acetate, β-myrcene, furfuryl alcohol, α-terpineol, benzyl alcohol, phenylethyl alcohol, phenol, pinene, eucalyptol, pyrone, p-methoxyacetophenone, 3,4-dimethoxyphenol, paeonol, 5-hydroxymethylfurfural, caryophyllene and other chemical components.

[0055] The components were mixed evenly according to the formula in Table 5 to prepare 1#~10# magnolia flower water-soluble flavors, wherein 10# flavor was used as a control and contained only magnolia flower extract and solvent.

[0056] Table 5 Magnolia flower water-soluble flavor formula

[0057] Note: “ / ” in the table means none.

[0058] The fragrance and fragrance holding capacity of the 1#~10# magnolia flower water-soluble flavors described in Table 5 were judged by smelling. The smelling judgment was made by 15 people. The average value of the specific judgment results is shown in Table 6: Table 6 Results of smelling the water-soluble essence of Magnolia flower

[0059] It can be seen from Table 6 that the overall fragrance and fragrance holding ability of magnolia flower water-soluble essence 1# are the best.

[0060] Taking Xinyue slim cigarettes as an example, the 1#~10# magnolia flower water-soluble flavors described in Table 5 were added to the cigarette filter to evaluate the aroma and sensory quality of the cigarette. The specific method is: weigh the magnolia flower water-soluble flavors described in Table 5 according to 0.1% of the weight of the cigarette, then dilute it with 75% ethanol to 1% of the weight of the cigarette, and inject it into the cigarette filter with a needle, among which the blank sample is applied with 75% ethanol according to 1% of the weight of the cigarette. The sensory quality effect evaluation adopts GB5606.4-2005 "Cigarette Part 4: Sensory Technical Requirements", and the number of evaluators is 15. The average values ​​of the specific evaluation results are shown in Tables 7 and 8.

[0061] Table 7 Evaluation results of cigarette aroma characteristics

[0062] It can be seen from Table 7 that the cigarette samples with 2#, 3# and 4# flavors have poor fireworks aroma and woody aroma, the cigarette samples with 5# and 6# flavors have poor fireworks aroma, the cigarette samples with 7#, 8# and 9# flavors have poor overall performance, the cigarette samples with 10# flavor have obvious medicinal smell and the worst overall flavor, and the cigarette samples with 1# magnolia flower water-soluble flavor have the strongest aroma characteristics.

[0063] Table 8 Cigarette sensory quality evaluation results (GB5606.4-2005)

[0064] It can be seen from Table 8 that the sensory quality scores of cigarette samples with 1# formula flavor are higher than those of other samples, and all indicators have been improved.

[0065] The evaluation results of cigarette aroma characteristics and sensory quality show that 1# formula flavor can give cigarettes rich magnolia flower aroma characteristics and effectively improve the smoking quality and sensory comfort of cigarettes.

[0066] Based on the data analysis of Tables 5-8, it is found that there is a significant synergistic effect between different components. This synergistic effect is mainly reflected in the following aspects: First, in the fragrance system, the 1# formula uses a balanced ratio of linalool (1 part), p-methoxyacetophenone (0.2 parts) and dimethoxyphenol (0.2 parts), showing the best aroma performance, scoring 3.8 points, 3.6 points and 3.9 points in eucalyptus, woody and floral characteristics, respectively. In contrast, the 2#-4# formulas increased the single fragrance to 1.4 parts, which led to a significant decrease in the aroma characteristic score, with the floral fragrance of the 2# formula dropping to 2.9 points and the woody fragrance of the 3# formula dropping to 2.8 points. This result shows that there is a clear synergistic effect between the fragrances, rather than a simple superposition of effects.

[0067] Secondly, the synergistic effect of the main fragrance and modifiers was verified by formulas 5# and 6#. The complete formula 1# contains benzyl alcohol (0.2 parts) and pyrone (0.2 parts) as modifiers, and it reaches 3.8 points and 4.73 points in terms of fragrance holding ability and harmonious tonality, respectively. When benzyl alcohol (formula 5#) is removed, the floral characteristics drop to 2.8 points; when pyrone (formula 6#) is removed, the fragrance holding ability drops to 3.5 points. This shows that modifiers not only have independent fragrance contributions, but more importantly, they can activate and enhance the effect of the main fragrance.

[0068] It is worth noting that this synergistic effect is not only reflected in the enhancement of aroma characteristics, but more importantly, it effectively improves the inherent medicinal aroma problem of magnolia flower extract. In formula 1#, the ethereal feeling provided by linalool and the fruity layer brought by p-methoxyacetophenone cleverly transform the medicinal aroma characteristics of magnolia flowers into a fresh and pleasant aroma. This can be confirmed by the excellent harmony score (4.73 points) of formula 1#, indicating that the formula has successfully achieved overall optimization of the aroma characteristics.

[0069] Third, from the perspective of cigarette application effects, the synergistic effect showed obvious concentration dependence. The ratio of 10 parts by weight of magnolia flower extract (after pretreatment) in the 1# formula made the aroma score reach 28.29 points, the harmony reached 4.73 points, and the total score reached 87.41 points. When the extract content was reduced to half (7#-8# formula), the total score dropped to about 84 points; when the extract was completely removed (9# formula), the total score was only 83.98 points. This shows that only within a specific concentration range can the components fully exert their synergistic effects.

[0070] It is particularly noteworthy that the formula design of the present invention retains the original aroma of tobacco while maintaining the characteristic aroma of magnolia flower. This is mainly due to two aspects: on the one hand, by accurately controlling the amount of magnolia flower extract (10 parts by weight of magnolia flower extract (after pretreatment)), it avoids excessive coverage of tobacco aroma; on the other hand, the synergistic effect of the flavoring agent and the modifier creates a layered aroma system, allowing the magnolia flower aroma to coexist harmoniously with the original tobacco aroma. This good integration is fully reflected in the sensory evaluation results. Formula 1 not only obtained the highest total score (87.41 points), but more importantly, it reached an ideal level in key indicators such as impurities (10.68 points) and irritation (17.59 points).

[0071] In addition, the solvent system (95% ethanol: propylene glycol = 2.75:1) also plays an important role in the synergistic effect. By adjusting the aroma release dynamics, the 1# formula achieved a 3.8-point aroma retention and a 21.62-point aftertaste score. At the same time, the solvent system effectively controlled the aroma release rate, maintaining the impurity and irritation indicators at appropriate levels of 10.68 and 17.59 points, respectively.

[0072] In summary, the experimental results clearly demonstrate the synergy between the components in the formula. This synergy is achieved through multiple dimensions, including the layered coordination of aroma construction (main aroma skeleton, combined aroma layer, modification details, fixed aroma), the tiered display of the release process (fast top aroma, stable middle aroma, and lasting base aroma), and good application effects (fusion with base materials and sensory enhancement).
