Compared with the prior art, the floret henna flower fragrance composition, the preparation method and the application thereof have the following beneficial effects:

in one aspect, the embodiment of the present invention provides a floret henna flower fragrance composition, which includes fragrance compounds and solvent adjuvants, wherein the fragrance compounds include the following 5 kinds: phenylacetaldehyde, farnesol, trans-nerolidol, linalool, methylheptenone; the olfactory thresholds in water for these 5 aroma compounds are all relatively low and they have the odor characteristics of "fruity", "floral", "fruity & floral" and "sweet & honey". Here, the 5 aroma compounds are respectively formulated into the henna floweringqince composition at corresponding concentrations, so that the henna floweringqince composition can simultaneously have the odor characteristics of "flower aroma", "sweet aroma & honey aroma" and "fruit aroma", without masking one or more of the odor characteristics; the fragrance of the floret henna flower fragrance composition can basically form a floret henna flower fragrance frame.

Further, the embodiment of the invention provides a henna floweringer composition, which comprises 9 aroma compounds, that is, 4 key aroma compounds, namely nonanal, phenethyl alcohol, geranyl acetone and n-hexanal, are added in corresponding concentrations on the basis of the above 5 aroma compounds. Wherein the 4 aroma compounds added have a lower aroma contribution than the 5 aroma compounds constituting the basic aroma skeleton, but are still perceivable by the human nose at very low concentrations. Moreover, 4 added aroma compounds have synergistic action and can also have synergistic action with the 5 aroma compounds forming the basic aroma framework, so that the three important aroma characteristics of the Lasiocladia dulcis flowers, namely ' flower aroma ', sweet aroma & honey aroma ' and ' fruit aroma ' are enriched; meanwhile, the hexanal and the nonanal in the added aroma compounds can enable the cymbidium odoratum aroma composition to show the aroma characteristics of 'grass aroma' and 'freshness'. The fragrance of the henna floweringqiu fragrance composition comprising 9 fragrance compounds provided by the embodiment of the invention can basically represent the fragrance characteristics of henna floweringqiu.

Further, the embodiment of the present invention provides a floret henna flower fragrance composition, which includes 13 kinds of fragrance compounds, that is, 4 kinds of more important fragrance compounds with corresponding concentrations are added on the basis of the above 9 kinds of fragrance compounds: 3-methyl-3-buten-1-ol, isovaleric acid, benzyl alcohol and acetophenone. The 4 aroma compounds added contribute less to the aroma of henna florida as a whole than the first 9 compounds, but are still more easily perceived by the human nose. Here, the 4 added aroma compounds act synergistically with other aroma compounds to further bring the two aroma characteristics "freshness" and "floral" of the floret cymbidium aroma composition very close to the floret cymbidium aroma. Moreover, the addition of two aroma compounds, i.e., isovaleric acid and 3-methyl-3-buten-1-ol, and the synergistic effect of the two aroma compounds with other aroma compounds make the aroma characteristics, i.e., "green grass aroma", of the florescent henna flower aroma composition provided by the embodiment more approximate to that of the florescent henna. The floret henna flower fragrance composition containing 13 fragrance compounds provided by the embodiment of the invention can achieve a good fragrance reduction effect.

Further, the embodiment of the present invention provides a henna floweringer composition, which includes 18 kinds of aroma compounds, that is, 5 auxiliary aroma compounds with corresponding concentrations are added on the basis of the above 13 kinds of aroma compounds: benzaldehyde, indole, 2, 6-di-tert-butyl-p-cresol, methyl palmitate and dibutyl phthalate. The 5 auxiliary aroma compounds contribute to the fragrance of henna variegate to a lesser extent and need to be perceived by the human nose at higher concentrations. Here, the synergistic effect between the 5 auxiliary aroma compounds and the synergistic effect with other aroma compounds make the floret henna flower fragrance composition provided by this embodiment approach the floret henna flower fragrance in the aspect of "fat fragrance", but the other fragrance characteristics are not significantly changed compared to the floret henna flower fragrance composition including 13 aroma compounds.

Further, the embodiment of the present invention provides a floret henna flower fragrance composition, which comprises 21 fragrance compounds, that is, 3 non-essential fragrance compounds are added in corresponding concentrations on the basis of the above 18 fragrance compounds: 3-methyl-2-butenal, 2-methylbutyric acid and styrene. The olfactory threshold of these 3 optional aroma compounds is very high and needs to be at very high concentrations to be perceived by the human nose with minimal contribution to the floret-lily aroma. After 2 kinds of unnecessary aroma compounds, namely 3-methyl-2-butenal and styrene, are added and other aroma compounds are synergistic, the overall aroma characteristics of the aromatic compound are closer to the aroma of the fresh flowers of the manila variegata.

In conclusion, the florida odorata composition provided by the embodiment of the invention is close to or has the natural fragrance of florida odorata, and embodies the characteristics that the florida odorata is rich in fragrance, and has honey fragrance, fruit fragrance and freshness, and has slight green grass fragrance and fat fragrance; and can be scaled up for use in industrial production to add to the associated product to impart aroma characteristics thereto.

On the other hand, the embodiment of the invention also provides a preparation method of the florida odorata composition, and during preparation, each aroma compound and solvent auxiliary materials are prepared into corresponding aroma compound solutions respectively; and then, taking out a set volume from each aroma compound solution, mixing, and adding a solvent auxiliary material to a constant volume to obtain the florida henna aroma composition.

Detailed Description

To further explain the technical means and effects of the present invention adopted to achieve the predetermined object, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

At present, the natural flower fragrance is researched by adopting a distillation method, a headspace-solid phase microextraction technology and CO₂Supercritical extraction technology, etc. Among them, although the distillation method can obtain a large amount of aroma extract, the distillation method is not suitable for extraction of flower materials which are likely to change in aroma at high temperature. Although the headspace-solid phase microextraction technology can integrate extraction, concentration and sample injection, the corresponding extract cannot be obtained. CO 2₂The supercritical extraction technology can obtain a relatively real aroma extract, but the equipment is expensive and the wide application is poor. Therefore, the extraction methods of aroma compounds used in the prior art cannot completely obtain aroma components of natural flowery odour.

Solvent-assisted flavor distillation (SAFE) is a mild and efficient volatile component extraction method which utilizes organic solvents or water to rapidly evaporate volatile compounds under low-temperature and high-vacuum conditions, so as to separate semi-volatile and nonvolatile components into components to be detected. Currently, solvent assisted flavor distillation is used primarily in the food field. The inventor of the invention finds that the extracted aroma profile is closer to the real sample for the first time.

Here, the solvent assisted flavor distillation (SAFE) technique is described in detail, and a specific solvent flavor distillation extraction apparatus is shown in fig. 1. Referring to fig. 1, the extraction device mainly comprises a sample bottle 1, a distillation bottle 2, a water-soluble pot 3, a receiving bottle 4, a first cold trap 5 and a second cold trap 6. The method uses a molecular vacuum pump to create a high-vacuum degree closed space, distills the aroma substances in a high-vacuum degree environment, can obviously reduce the boiling point of the volatile compounds, enables the volatile compounds to be boiled, evaporated and separated under a low-temperature condition, and is combined with a very low-temperature cold trap device (liquid nitrogen is used as a condensing agent). The method can effectively separate volatile compounds from nonvolatile compounds and completely retain the main aroma profile of the volatile compounds. SAFE is currently considered as a gold standard for extracting volatile components from a matrix, and can be used to separate flavor compounds from different matrices, such as solvent extracts or aqueous foods, without being affected by other components in the matrix (i.e. amino acids, organic acids and phenolic acids), the extracts being able to maintain the original natural flavor of the sample. At present, SAFE is not reported to be used for fresh flower fragrance research.

The experimental method for extracting the henry sage herb essence from fresh henry sage herb flowers by adopting a solvent-assisted flavor distillation technology adopts methylene dichloride as a solvent, and comprises the following specific extraction steps: as shown in figure 1, a sample (henna multiflora) is placed in a sample bottle 1, the sample is placed in a distillation bottle 2 through a knob, the sample in the distillation bottle 2 is heated by a water bath at 45 ℃ in a water-soluble pot 3, the sample is distilled into gas under the condition of high vacuum, the gas is carried to the right side of the instrument by circulating water at 40 ℃ (the circulating water is distributed in the figure except for the sample bottle 1, the water-bath pot 3, a first cold trap 5 and a second cold trap 6), liquid nitrogen is filled in two positions of the first cold trap 5 and the second cold trap 6, and finally steam is condensed into a receiving bottle 4. The solution in the receiving bottle 4 is subjected to reduced pressure concentration to remove dichloromethane, and the concentrated solution is the henna multiflora extract.

The fragrance sensory evaluation is carried out on the multi-flower henna fragrance extract (namely, SAFE extract) extracted by the solvent-assisted flavor distillation technology, and the SAFE extract is found to be capable of completely retaining the fragrance characteristics of the multi-flower henna flowers, and embodies the characteristics of rich fragrance of the multi-flower henna flowers, honey fragrance, fruit fragrance, freshness, green grass fragrance and fat fragrance.

However, SAFE extracts cannot be scaled up for industrial production. Therefore, the inventor of the invention carries out various researches on SAFE extracts, obtains inspiration from henna multiflora and henna multiflora fresh flower extracts, uses the henna multiflora and henna as positive control for sensory evaluation of fragrance, and combines and compounds various monomer fragrance compounds to obtain a composition with natural fragrance characteristics of henna multiflora, namely, a henna multiflora flower fragrance composition. The henry creeper flower fragrance composition can accurately reflect the fragrance characteristics of the henry creeper flowers and the SAFE extract, and can be used in industrial production in an enlarged way to be added into related products to endow the fragrance characteristics with the relevant products.

The following detailed description of the formulation of the henna floweringqince composition by means of specific examples is as follows:

example 1

The embodiment provides a floret henry magnolia flower fragrance composition, which is composed of a fragrance compound and a solvent auxiliary material. Wherein, the solvent auxiliary material is selected from 1, 2-propylene glycol, but not limited to 1, 2-propylene glycol, and other solvent auxiliary materials can also be selected. The aroma compounds of this example were the following 5 aroma compounds: farnesol, trans-nerolidol, methylheptenone, phenylacetaldehyde, linalool; in the floret henna flower composition of the embodiment: the concentration of farnesol is 1078.59-1198.47mg/L, preferably 1130-1145mg/L, the concentration of trans-nerolidol is 6780.76-7161.92mg/L, preferably 6960-69880 mg/L, the concentration of methyl heptenone is 44.1-45.1mg/L, preferably 44.3-44.9mg/L, the concentration of phenylacetaldehyde is 1129.27-1207.71mg/L, preferably 1165-1171mg/L, and the concentration of linalool is 183.57-186.03mg/L, preferably 184.3-184.9 mg/L.

Referring to table 1 below, this example provides 5 aroma compounds in a floret henna composition: the olfactory threshold values in water of farnesol, trans-nerolidol, methylheptenone, phenylacetaldehyde and linalool are very low, and the concentration is relatively high, so that the farnesol, trans-nerolidol, methylheptenone, phenylacetaldehyde and linalool have very important effect on the fragrance of the floret henna flower fragrance composition. And, they have the odor characteristics of "floral", "fruity" and "sweet & honey". In this embodiment, the 5 kinds of aroma compounds are respectively prepared into the florida odorifera composition at corresponding concentrations (see the concentration ranges described above), so that not only the florida odorifera composition can have the odor characteristics of "flower fragrance", "sweet fragrance & honey fragrance" and "fruit fragrance", but also the fragrance characteristics of one or more of the florida odorifera compositions cannot be covered after the combination of the 5 kinds of aroma compounds, and the fragrance of the florida odorifera composition can basically form a frame of the florida odorifera fragrance.

Here, the sensory evaluation test of fragrance was performed on the henna floweringer composition of the present example, specifically as follows:

(1) preparation of single aroma compound solution: 5 kinds of aroma compound solutions, each having a volume of 5mL, were prepared by preparing 5 kinds of aroma compound solutions for preparing the florida odorata composition of this example using 1, 2-propylene glycol as a solvent adjuvant. Wherein the concentration of each aroma compound solution is as follows: the concentration of phenylacetaldehyde is 233.7mg/L, the concentration of farnesol is 227.6mg/mL, the concentration of trans-nerolidol is 1394.27mg/mL, the concentration of linalool is 36.96mg/mL, and the concentration of methylheptenone is 8.92 mg/L.

(2) Preparation of floret henna composition: mixing 25 μ L of each aroma compound solution, adding solvent 1, 2-propylene glycol, and diluting to 5mL to obtain the desired composition. Here, the concentration of phenylacetaldehyde in the henna floweringqince composition is 1168.5mg/L, the concentration of farnesol is 1138mg/L, the concentration of trans-nerolidol is 6971.35mg/L, the concentration of linalool is 184.8mg/L, and the concentration of methylheptenone is 44.6 mg/L.

(3) Sensory evaluation of fragrance of the floret henna composition: the floret henna fragrance composition was compared to the floret henna flower fragrance and radar plots were used to characterize the effect of fragrance reduction. The fragrance characteristics of the henna multiflora and henna multiflora fragrance composition are divided into 7 types (namely, fragrance, freshness, fruit fragrance, rancidity and mildew fragrance, sweet fragrance and honey fragrance, green grass and fat fragrance), 7 sensory evaluation groups smell and score the compositions (7 sensory evaluation groups are subjects with long-time olfactory training), the fragrance is fully divided into 10 points, and the average value is taken.

(4) Sensory evaluation of aroma: sensory evaluation of aroma the results are shown in FIG. 2; as can be seen from fig. 2, the floret henna composition formulated in this example has both "floral", "fruity", "fresh", and "sweet & honey" odor characteristics. Due to the high content of trans-nerolidol, phenylacetaldehyde and farnesol aroma compounds in the henna flower fragrance composition prepared in the embodiment, the aroma of the henna flower fragrance composition and the aroma of the henna flower fragrance composition prepared by the method are similar to each other in the sensory indexes of fruit aroma, flower aroma, sweet aroma and honey aroma, but are greatly different from the henna flower fragrance in other sensory indexes. Therefore, the floret henna flower fragrance composition in the embodiment is not sufficient to determine the fragrance characteristics of floret henna, but the floret henna flower fragrance composition prepared in the embodiment can form the basic skeleton (framework) of the floret henna flower fragrance due to the odor characteristics of fruit fragrance, flower fragrance, sweet fragrance and honey fragrance.

Example 2

The embodiment provides a floret henry magnolia flower fragrance composition, which is composed of a fragrance compound and a solvent auxiliary material. Wherein, the solvent auxiliary material is 1, 2-propylene glycol, but is not limited to 1, 2-propylene glycol, and other solvent auxiliary materials can also be selected. The aroma compounds are the following 9 aroma compounds: phenylacetaldehyde, farnesol, trans-nerolidol, linalool, methylheptenone, nonanal, phenethyl alcohol, geranylacetone, n-hexanal. Wherein, in the floret henna flower composition: the concentration of farnesol is 1078.59-1198.47mg/L, preferably 1130-1145mg/L, the concentration of trans-nerolidol is 6780.76-7161.92mg/L, preferably 6960-6980mg/L, the concentration of methyl heptenone is 44.1-45.1mg/L, preferably 44.3-44.9mg/L, the concentration of phenylacetaldehyde is 1129.27-1207.71mg/L, preferably 1165-1171mg/L, the concentration of linalool is 183.57-186.03mg/L, preferably 184.3-184.9mg/L, the concentration of nonanal is 20.56-20.9mg/L, preferably 20.70-20.76mg/L, the concentration of phenethyl alcohol is 295.82-301.25mg/L, preferably 298.5-298.6mg/L, the concentration of geranylacetone is 36.06-41.4mg/L, preferably 38.7-38.8mg/L, The concentration of the n-hexanal is 63.42-66.46mg/L, preferably 65.0-66.0 mg/L.

The henna multiflora champ composition provided by the embodiment is prepared by adding 4 key aroma compounds, namely nonanal, phenethyl alcohol, geranyl acetone and n-hexanal, on the basis of taking 5 aroma compounds, namely phenylacetaldehyde, farnesol, trans-nerolidol, linalool and methyl heptenone, as basic aroma frameworks. Referring to Table 1, the olfactory threshold of the 4 aroma compounds added in this example is higher than that of the 5 aroma compounds constituting the basic aroma skeleton, but still can be perceived by the human nose at a very low concentration. Moreover, the 4 kinds of aroma compounds added in the embodiment have synergistic effect, and have synergistic effect with 5 kinds of aroma compounds forming the basic aroma skeleton, so as to enrich the extremely important aroma characteristics of the three florida variegates, namely ' flower aroma ', sweet aroma & honey aroma ' and ' fruit aroma '; meanwhile, the hexanal and the nonanal in the added aroma compounds enable the florida odorata composition provided by the embodiment to embody the aroma characteristics of 'grass smell' and 'freshness'. However, the sensory evaluation score of "fat aroma" of the floret henna flower composition provided in this example was not satisfactory.

(1) preparation of single aroma compound solution: using 1, 2-propylene glycol as solvent adjuvant to prepare fragrance compound solutions for 9 fragrance compounds used for preparing the henna floweringqince composition of the present example, 9 fragrance compound solutions were prepared, and the volume of each fragrance compound solution was 5 mL. Wherein the concentration of each aroma compound solution is as follows: the concentration of phenylacetaldehyde is 233.7mg/L, the concentration of farnesol is 227.6mg/mL, the concentration of trans-nerolidol is 1394.27mg/mL, the concentration of linalool is 36.96mg/mL, the concentration of methylheptenone is 8.92mg/L, the concentration of phenethyl alcohol is 59.712mg/mL, the concentration of nonanal is 4.146mg/mL, the concentration of geranylacetone is 7.746mg/mL, and the concentration of n-hexanal is 13.008 mg/mL.

(2) Preparation of floret henna composition: mixing 25 μ L of each aroma compound solution, adding 1, 2-propylene glycol to the total volume of 225 μ L, and diluting to 5mL to obtain the florida henna flower aroma composition. Wherein, the prepared floret henna flower fragrance composition comprises the following components: the concentration of phenylacetaldehyde is 1168.5mg/L, the concentration of farnesol is 1138mg/L, the concentration of trans-nerolidol is 6971.35mg/L, the concentration of linalool is 184.8mg/L, the concentration of methylheptenone is 44.6mg/L, the concentration of phenethyl alcohol is 298.56mg/L, the concentration of nonanal is 20.73mg/L, the concentration of geranylacetone is 38.73mg/L, and the concentration of n-hexanal is 65.04 mg/L.

(3) Sensory evaluation of fragrance of the floret henna composition: comparing the floret henna flower fragrance composition with the floret henna flower fragrance, and using a radar chart to represent the fragrance reduction effect. The fragrance characteristics of the henna multiflora and henna multiflora fragrance composition are divided into 7 types (namely, fragrance, freshness, fruity fragrance, rancidity and mildew fragrance, sweet fragrance and honey fragrance, green grass and fat fragrance), 7 sensory evaluation groups smell and score the compositions (7 sensory evaluation groups are subjects with long-time olfactory training), the fragrance is fully divided into 10 points, and the average value is taken.

(4) Sensory evaluation of aroma: sensory evaluation of aroma the results are shown in FIG. 3; as can be seen from fig. 3, after adding key aroma compounds having aroma characteristics of "floral aroma", "sweet aroma & honey aroma" such as phenethyl alcohol and methyl heptenone, the sensory evaluation of the three aroma characteristics of "fruity aroma", "sweet aroma & honey aroma" and "floral aroma" of the floret henna aroma composition of the present example is very close to that of flowers. Meanwhile, after the n-hexanal is added, the characteristic odor of the green grass and the fresh grass of the fragrance regroup is obviously improved, and the 9 fragrance compounds in the embodiment have synergistic effect, so that the manila variegata fragrance composition in the embodiment has the scores close to the fragrance of the natural manila variegata in each fragrance description. Therefore, the fragrance of the henna floweringer composition in the embodiment is considered to be basically representative of the fragrance characteristics of henna floweringer.
