Description

  The present invention relates to a method for producing a flavor-enhanced essence flavor by extracting an oil-soluble raw material using an emulsifier and an extraction solvent.

In recent years, a wide variety of beverages and foods have been put on the market due to diversification of consumer preferences.
As the needs for flavors, those that increase palatability are required, and for low-calorie beverages, functional beverages, etc., masking of the taste derived from ingredients such as sweeteners is also required. In particular, for flavors for beverages that give a citrus flavor, essence flavors and emulsified flavors for uniform dispersion in a solution are required, and in recent years, development of solubilized flavors using emulsifiers has undergone significant evolution.

Most of the fragrances such as natural fragrances, synthetic fragrances and blended fragrances are oil-soluble, and it is necessary to make them water-soluble by some method in order to perfume an aqueous cosmetic product. There are two methods: a method in which an aroma component that is part of an oil-soluble component is dissolved in a water-soluble solvent such as hydrous alcohol (essence), and a method in which fine particles are made using an emulsifier and dispersed in water (non-patented). Reference 1).
As a method for obtaining an essence fragrance using an oil-soluble raw material, alcohols such as ethyl alcohol and propyl alcohol, water, hydrous alcohol and the like are mainly used as an extraction solvent. This is a simple method for liquid-liquid extraction of essential oil with a solvent (Non-patent Document 2). However, in this production method, flavor and flavor components are not efficiently extracted from the essential oil, and the flavor and flavor cannot be given sufficient strength.

  Therefore, in order to efficiently obtain a stable essence fragrance that contains abundant fragrance components and taste components from oil-soluble raw materials and that can be easily and transparently dissolved in water, and that remains transparent during subsequent storage. A method for producing an aqueous extract using an oil-soluble raw material obtained by extraction from an edible raw material using a mixed solvent of ethyl alcohol, a water-miscible organic solvent other than ethyl alcohol and / or an electrolyte, ethyl alcohol and water has been proposed. ing. The oil-soluble raw material obtained by extraction from the edible raw material includes essential oils such as citrus essential oil, and oils. As the electrolyte, sodium sulfate, sodium chloride, potassium chloride, and calcium hydrochloride are used. As the miscible organic solvent, propyl alcohol, isopropyl alcohol or a mixture thereof is used (Patent Document 1).

  However, in this manufacturing method, propyl alcohol, isopropyl alcohol or a mixture thereof actually used as a water-miscible organic solvent has a unique flavor, and particularly when an oil-soluble raw material other than citrus essential oil is used, Remarkably inhibits the flavor of essence flavors.

  Further, a terpene-containing liquid composition containing terpenes as oil-soluble raw materials, polyglycerin fatty acid ester and water as three essential components and capable of solubilizing terpenes by adjusting the holding temperature is a cosmetic, It has been proposed for pharmaceuticals and foods (Patent Document 2). Further, a transparent gel containing terpenes comprising 5 to 30% by weight of a hydrophilic polyol fatty acid ester, 30 to 80% by weight of an oil-soluble substance containing 50% by weight or more of a terpene and 10 to 30% by weight of an aqueous polyol solution. Compositions have also been proposed for cosmetics, pharmaceuticals and foods (Patent Document 3).

However, all of these documents use a polyol as a solvent, and do not extract an essence perfume from an oil-soluble raw material.
An emulsified composition is produced. In addition, it is extremely difficult to make it transparent even when added to a wide variety of beverages and stored for a long time.

  Furthermore, 1-70 parts by weight of a polyglycerin fatty acid ester, 0.1-50 parts by weight of water and 1-90 parts by weight of a polyhydric alcohol are mixed with 1-70 parts by weight of a water-insoluble substance, thereby emulsifying and solubilizing. A method for producing a characteristic emulsified solubilized solution has also been proposed (Patent Document 4). However, in this method, when a highly viscous emulsified fragrance using a large amount of polyhydric alcohol is used in a beverage, the fragrance (flavor wreath) tends to deteriorate. And like patent document 3, it is very difficult to make it transparent even when it is added to a wide variety of beverages and stored for a long time.

  Furthermore, (a) edible oily material such as essential oil, (b) at least one emulsifier selected from the group consisting of HLB12 or higher polyglycerin fatty acid ester, enzyme-treated lecithin and quilla extract, (c) polyvalent In the process for producing an emulsion composition for foods and beverages in which a composition comprising alcohol and (d) water is emulsified, the emulsification treatment is performed under reduced pressure, and the average emulsion particle size of the emulsion composition is 0.2. There has been proposed a method for producing an emulsion composition for foods and drinks, characterized in that it is not more than micron (Patent Document 5). However, in this method, when the emulsification treatment is performed under a reduced pressure condition, not only the original flavor of the edible oily material is inhibited, but also a large-scale equipment such as a decompression device is required.

  Furthermore, it is obtained by emulsifying a composition comprising (a) an edible oily material such as essential oil, (b) purified polyglycerin fatty acid ester, (c) polyhydric alcohol, and (d) water. An alcohol-resistant transparent emulsion composition is also proposed (Patent Document 6). However, this method requires much labor such as using hexane or confirming using thin layer chromatography when purifying the polyglycerol fatty acid ester. Furthermore, in this method, the polyhydric alcohol is used to maintain the stability of the emulsion, but it is necessary to stir at a high speed of 8000 rpm during emulsification. And since polyhydric alcohol is used in this product, there is a tendency for the fragrance (flavor release) to deteriorate.

  It consists of edible essential oils dispersed in a matrix consisting of water and alcohols such as ethyl alcohol, propylene glycol, glycerin, etc., edible essential oil 1-25%, at least one surfactant 1-35%, alcohol and water 25 An edible concentrated fine emulsion composed of ˜80%, which is stable to heat and can be stored for a long time has been proposed as a flavor carrier (Patent Document 7). However, in this method, edible essential oils include orange oil, lime oil, bergamot oil, and grapefruit oil. As a surfactant, a nonionic surfactant of HLB 10-18 is used in addition to an anionic surfactant. However, the emulsifier, ethyl alcohol, water and essential oil are simply mixed to produce an emulsified composition, and the essence flavor is not extracted from the oil-soluble raw material.

Then, if necessary, separation of the extraction solvent layer and filtration of the precipitate may be performed after standing at low temperature.
This essence flavor can be added as a flavoring agent to beverages, foods, etc., and is transparent even when stored for a long period of time.

The present invention provides the following invention contents.

Food / beverage products which added the essence fragrance | flavor of 9.8.

  According to the present invention, it is possible to obtain an essence fragrance excellent in flavor from an oil-soluble raw material by a simple production method and without requiring large equipment. The essence fragrance obtained by the present invention contains abundant necessary fragrance components and taste components, dissolves easily and transparently in water, does not cause turbidity when added to a wide variety of beverages, foods, etc. Transparency and stability are maintained during subsequent long-term storage. Moreover, it has an advantageous effect of being excellent in flavor release (scented).

Hereinafter, the present invention will be specifically described.
The oil-soluble raw materials used in the present invention include essential oils, vegetable oils, animal fats and the like, but mainly essential oils, generally steam distillation method, pressing method, extraction from plant raw materials such as citrus It is an essential oil obtained by various methods such as law.

  Specific examples include citrus essential oils such as orange oil, lemon oil, grapefruit oil, bergamot oil, yuzu oil, lime oil, mandarin oil, and tangerine oil.

  Since these oil-soluble raw materials cannot be directly used for aqueous beverages and foods, they must be made water-soluble by some method. Therefore, processing methods have been used in the past to dissolve aroma components, which are part of oil-soluble components, in water-soluble solvents such as water-containing alcohol. There is a demand for efficient flavoring of citrus flavors to foods, such as standing, taste, and bitterness. The peel feeling is a sensory feature representing the flavor characteristics of citrus fruits, particularly the pericarp, with respect to the citrus-flavored fragrance, as used in Japanese Patent Application Laid-Open No. 2010-88348 "Scented Citrus-like Flavor Enhancer". Used as an expression. Peel is an indicator of the taste of citrus with a bitter taste, and when there is a peel, the citrus character is emphasized and is generally preferred in beverages and foods. In the product of the present invention, the flavor derived from the essential oil is efficiently incorporated into the fragrance preparation, so that the flavored food can have a better citrus flavor.

Moreover, in this invention, citrus essential oils, such as essential oils, such as bergamot essential oil and orange essential oil, and synthetic fragrance | flavors can also be used as an oil-soluble raw material. Synthetic fragrances are used for characterizing flavor and reinforcing flavor. There are many synthetic fragrances that are oil-soluble, and adding synthetic fragrances after extraction of essential oils may cause turbidity or oil floating when added to beverages. Can be dispersed uniformly and transparently. Here, the synthetic fragrance is made by a method using a chemical reaction, and has a chemical structure that is clear and has a fragrance, and refers to hydrocarbons, alcohols, fatty acids, esters, lactones, One kind selected from aldehydes, ketones, ethers, nitrogen-containing compounds, sulfur-containing compounds, or a mixture of two or more kinds in an arbitrary ratio. For example, hexanol, geraniol, nerolidol for alcohols, butyl acetate, linalyl acetate, ethyl butyrate, benzyl benzoate for esters, octanal, decanal, phenylacetaldehyde for aldehydes, nootkatone for terpenes (with molecular formula C ₁₅ H ₂₂ O A kind of sesquiterpene ketone), limonene, and the like. For example, in order to make the flavor of bergamot essential oil more fresh, synthetic fragrance of 0.1 g of hexanol and 2 g of linalyl acetate can be combined with 10 g of bergamot essential oil. Further, as an example, in order to emphasize the flavor (peel feeling) of the peel of orange essential oil, 0.3 g of octanal and 0.1 g of decanal can be combined with 10 g of orange essential oil. Further, in order to emphasize the characteristic aroma of grapefruit essential oil and enhance the peel feeling, it is possible to combine 1 g of synthetic nutrato with 10 g of grapefruit essential oil. Although one kind of synthetic fragrance can be used, a more complex flavor can be expressed by combining two or more kinds.

  In addition, the polyglycerin fatty acid ester as an emulsifier to be used is nonionic, and in the present invention, in view of the transparency of the essence fragrance and the influence of taste on beverages and the like, a polyglyceride having an HLB of 15.5 or more is particularly preferred. Glycerin fatty acid esters, especially decaglycerin fatty acid esters are desirable. Here, HLB means a hydrophilic-lipophilic balance. The lower the HLB, the more lipophilic, the higher the hydrophilicity. Further, decaglycerin fatty acid esters exist in various combinations depending on the number of carbon atoms and the degree of esterification of the constituent fatty acids, saturation and unsaturation, and select saturated fatty acids having 12 to 14 carbon atoms, more preferably myristic acid and lauric acid. Is desirable. The degree of esterification is preferably a monoester type, and specific examples include decaglycerin monomyristic acid ester and decaglycerin monolauric acid ester. Specific examples of commercially available emulsifiers include Mitsubishi Chemical Foods Corporation Ryoto (registered trademark) polyglycerin M-7D, Sakamoto Pharmaceutical Co., Ltd. SY Glister MM-750, and the latter as Examples thereof include Ryoto-polyglycerester L-7D, Nikko Chemicals Corporation NIKKOL Decaglyn 1-LVEX, and the like. When HLB is lower than 15.5, or when the number of carbon atoms of the constituent fatty acid is less than 12 or greater than 14, the essence fragrance may become cloudy, or it may become cloudy when essence fragrance is added to the beverage. There is a case.

  Alcohols include monohydric alcohols and polyhydric alcohols, and further saturated and unsaturated. In the present invention, monohydric saturated alcohols are preferred. Even in the case of monohydric alcohols, there are lower alcohols to higher alcohols. In the present invention, lower alcohols are desirable, and ethyl alcohol is preferred in view of utilizing the fragrance of the oil-soluble raw material. As described above, propyl alcohol, isopropyl alcohol, butyl alcohol or a mixture thereof has a unique flavor, and particularly when an oil-soluble raw material other than citrus essential oil is used, the flavor of the essence flavor is significantly inhibited. Further, in the case of higher alcohols, not only has a unique flavor, but also hydrophilicity is weakened, which causes turbidity when added. Furthermore, when polyhydric alcohol is used, it becomes a water-soluble fragrance | flavor composition with high viscosity, and there exists a tendency for fragrance formation (flavor release) to worsen.

  The method for producing the essence fragrance of the present invention is not particularly limited, but after adding polyglycerin fatty acid ester to ion-exchanged water in a tank and then adding ethyl alcohol, stirring and mixing the solvent, oil Add soluble raw material, stir and mix, then let stand at low temperature, separate oil in upper tank (oil layer) and lower layer (extract solvent layer) in tank, and extract oil layer by removing extract solvent layer from under tank and extract The precipitate is filtered from the solvent layer to obtain the essence flavor of the present invention. If necessary, separation of the extraction solvent layer and filtration of the precipitate may be performed after standing at low temperature.

  In the method for producing the essence fragrance of the present invention, a mixed extraction solvent consisting of ion-exchanged water, an emulsifier and 95% ethyl alcohol is used. %, Preferably 1 to 10%. In addition, the ratio of ethyl alcohol and ion-exchanged water in the mixed extraction solvent layer is not particularly limited, but when the ratio of ethyl alcohol is too high or too low, the essence fragrance itself of the present invention or the essence fragrance is added to the beverage. There is a tendency for the transparency of the time to be insufficient. Therefore, the ratio of ethyl alcohol in the solvent layer is 55 to 75%, particularly preferably 60 to 70%. The oil-soluble raw material is preferably 1 to 10% with respect to the extraction solvent layer although it depends on the type.

In the extraction step of the present invention, the stirring conditions are not particularly limited, but are desirably 300 to 600 rpm, preferably 450 to 550 rpm. If the stirring speed is 200 rpm or less, the entire solution may not be stirred uniformly. The extraction time can be set to an arbitrary time, but is preferably 2 to 30 minutes, and particularly preferably 15 minutes. If the extraction time is too short, the solution may not be homogenized. If the extraction time is too long, the ethyl alcohol may be scattered. The extraction temperature can be extracted at an arbitrary temperature, but is -15 ° C to 70 ° C, preferably 10 ° C to 40 ° C. When the extraction temperature is too low, the emulsifier may be precipitated depending on the type of the emulsifier. When the extraction temperature is too high, the essential oil aroma modification may be accelerated and the flavor may be deteriorated. For example, the essential oil is composed of various fragrances, but limonene, which is mainly contained in the orange essential oil, is changed to terpineol by excessive application of heat, and in citral, it is changed to cresol. May change to a different flavor than the essential oil.
The steps of the present invention are shown in the flowchart in Table 1.

  Commercially available emulsifiers such as Ryoto polyglycerester manufactured by Mitsubishi Chemical Foods, Inc., Decaglyn manufactured by Nikko Chemicals, etc. are usually composed of a mixture containing various molecular species, and all of the objects of the present invention are achieved. It is not necessarily composed of components having the necessary functions. For example, a polyglycerol fatty acid ester is produced by reacting a polyglycerol mixture with a fatty acid mixture. The main component is a monoester, but in addition to these, there are various mixtures in which higher esters such as diesters and triesters, unreacted polyglycerin and the like are present.

  The unreacted portion that is unavoidably generated during the production of the emulsifier does not exhibit sufficient hydrophilicity, and may lead to destabilization of the essence fragrance itself, or destabilization of the beverage to which the essence fragrance is added. In particular, in beverages that must be stored at low temperatures, it is necessary to prevent instability. Therefore, in the present invention, separation of the extraction solvent layer and filtration of the precipitate are carried out after standing at low temperature, and oil-soluble raw materials, mainly essential oils other than fragrance components and emulsifier components that are stably incorporated into the mixed solvent. , And can be selectively removed as precipitates.

  The essence flavor of the present invention is any food or drink, for example, fermented milk, lactic acid bacteria beverages, milk beverages, soft drinks, fruit beverages, vegetable beverages, carbonated beverages, tea beverages (tea, oolong tea, green tea, etc.) It can be used for flavoring coffee beverages, functional beverages, liquor beverages such as alcoholic beverages, desserts such as jelly, jams such as marmalade, sauces such as fruit flavor sauces, and frozen desserts. The compounding quantity to the food-drinks of this invention can illustrate the range of 0.001 to 5%.

  Examples relating to the present invention will be described below. However, the present invention is not limited to these examples, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention. Is possible.

[Comparative test of essence fragrances with and without emulsifier use]
In the production of the essence fragrance, the effect on the water solubility of the essence fragrance is tested when an emulsifier is used and when it is not used.

It was found that the essence flavor of Example 3-5 using 20% of the emulsifier was 96.5%, and the essence flavor of Example 3-6 using 25% of the emulsifier was 92.6%. The value showed a transmittance. Moreover, the essence fragrance | flavor which does not use the emulsifier of the comparative example 2 was 100.0%. As described above, since the transmittance of water to which these essence fragrances are added is desirably 97.0% or more, the amount of the emulsifier used in the present invention is preferably 10% or less. The results are shown in Table 11.

[Example 4]
[Verification of alcohol use ratio]
Depending on the type, the essential oil used in the essence fragrance may cause turbidity in the essence fragrance or cause white turbidity when a beverage is added. In particular, grapefruit essential oil has such a tendency, but in the present invention, by controlling the ratio of ethyl alcohol, it can be transparently dispersed when added to a beverage. Then, the influence which the usage-ratio of ethyl alcohol in the extraction solvent layer using the emulsifier of this invention has on the water solubility of an essence fragrance | flavor using grapefruit essential oil was investigated.

[Example 4-1]
[Essence perfume using 55% ethyl alcohol in the solvent layer]
In a solvent layer, 1 g of Ryoto-polyglycerester M-7D, HLB16.0, which is decaglycerin myristic acid ester, was dissolved at 43 ° C. in 42 g of ion-exchange water so that ethyl alcohol was 55% and emulsifier was 1.0%. Then, 58 g of 95% ethyl alcohol was mixed, 10 g of grapefruit essential oil was added, and the others were carried out in the same manner as in Example 1. As a result, 61 g of a slightly turbid essence fragrance was obtained.

[Example 4-2]
[Essence perfume using 60% ethyl alcohol in the solvent layer]
Dissolve 1 g of Ryoto-polyglycerester M-7D, HLB16.0, which is decaglycerin myristic acid ester, at 36 ° C. in 36 g of ion-exchanged water so that ethyl alcohol is 60% and emulsifier is 1.0% in the solvent layer. Then, 64 g of 95% ethyl alcohol was mixed, 10 g of grapefruit essential oil was added, and the others were carried out in the same manner as in Example 4-1, to obtain 61 g of an essence flavor.

[Example 4-3]
[Essence perfume using 70% ethyl alcohol in the solvent layer]
1 g of Ryoto-polyglycerester M-7D, HLB16.0, which is decaglycerin myristic acid ester, is dissolved at 43 ° C. in 26 g of ion-exchanged water so that ethyl alcohol is 70% and emulsifier is 1.0% in the solvent layer. Then, 74 g of 95% ethyl alcohol was mixed, 10 g of grapefruit essential oil was added, and the rest was carried out in the same manner as in Example 4-1, to obtain 60.5 g of an essence flavor.

[Example 4-4]
[Essence fragrance using 75% ethyl alcohol in the solvent layer]
Dissolve 1 g of Ryoto-polyglycerester M-7D, HLB16.0, which is decaglycerin myristic acid ester, in 20 g of ion-exchanged water so that ethyl alcohol is 75% and emulsifier is 1.0% in the solvent layer at 43 ° C. 80 g of 95% ethyl alcohol was mixed, 10 g of grapefruit essential oil was added, and the rest was carried out in the same manner as in Example 4-1, to obtain 62.2 g of essence flavor.

[Comparative Example 3]
[Essence fragrance extracted from grapefruit essential oil without emulsifier]
10 g of grapefruit essential oil was added to a mixture of 44 g of ion-exchanged water and 66 g of 95% ethyl alcohol so that the ethyl alcohol was 57% in the solvent layer. 75 g was obtained.

[Test Example 5]
[Solubility evaluation of essence fragrances with different alcohol use ratios]
In the result of setting the ratio of ethyl alcohol in Example 4-1 to 55%, the essence fragrance itself was turbid, so the solubility evaluation was not performed.
The essence fragrance | flavor from which the usage-ratio of the alcohol obtained in Example 4-2, 4-3, and 4-4 differs was added to 100 g of ion-exchange water, and was stirred, and each test liquid was obtained. When the transmittance of this test solution was measured in the same manner as in Test Example 1, the essence flavors obtained by using 60% and 70% of the ethyl alcohol of Examples 4-2 and 4-3, respectively, were 100%. The values were 0.0% and 98.9%, and it was found that they were dissolved in water in an extremely transparent and uniform manner. The essence fragrance | flavor which used 75% of ethyl alcohol of Example 4-4 showed the value of 95.8%. The essence fragrance | flavor which does not use the emulsifier of the comparative example 3 was 100.0%. Considering the transparency of these essence fragrances, it has been found that in the present invention, when grapefruit essential oil is used, it is preferable to use ethyl alcohol in the range of 60% to 70%. The results are shown in Table 12.

[Manufacture of essence fragrance using a mixture of essential oil and synthetic fragrance]
In essence fragrances, synthetic fragrances are often used with essential oils for the purpose of reinforcing or characterizing the fragrance. When a synthetic fragrance is added to the fragrance, if the synthetic fragrance is added after the essence fragrance is extracted, the synthetic fragrance may be separated without being uniformly dispersed. Therefore, the synthetic fragrance is added before the extraction of the essence fragrance. Then, the influence which the extraction of the essence fragrance | flavor of this invention has on having added the synthetic fragrance | flavor to the extraction raw material was tested. Furthermore, it compared with the case where a synthetic fragrance | flavor was added to the essence fragrance | flavor after extraction later.

[Combined use of synthetic fragrance as raw material for extraction]
[Example 5-1]
[Manufacture of essence fragrances using an emulsifier and a mixture of grapefruit essential oil and 1g Nootkaton as a synthetic fragrance]
[Essence fragrance using decaglycerin myristic acid ester, C: 14, HLB16.0 and synthetic fragrance added]
Except for using 10 g of grapefruit essential oil in Example 4-2, the same operation as in Example 4-2 was performed except that 10 g of grapefruit essential oil was added with 1 g of Nootkaton to obtain 69 g of essence flavor. Nootkaton is a kind of sesquiterpene ketone, one of the compounds with the characteristic scent of grapefruit, and was used to reinforce the peel of grapefruit essential oil.

[Example 5-2]
[Addition after extraction of synthetic fragrance]
[Essence fragrance in which synthetic fragrance is added to essence fragrance extracted using decaglycerin myristic acid ester, C: 14, HLB16.0]
In order to reinforce the peel feeling of grapefruit essential oil, 0.1 g of Nootkaton was added to 11 g of the essence flavor of Example 4-2, and mixed with stirring to obtain 11.1 g of a water-soluble composition.

[Example 8]
[Comparison of the product of Example 1 of Patent Document 6 and the essence flavor of the present invention]
In Example 1 of Patent Document 6, polyglycerin fatty acid ester is used as an essential oil as an emulsifier and treated with a mixed solvent of polyhydric alcohol and water as an extraction solvent, but in the present invention, polyhydric alcohol is not used as an extraction solvent. The difference is that it is treated with a mixed solvent of ethyl alcohol and water. Therefore, both are compared.

[Comparative test of water-soluble fragrance composition using polyhydric alcohol as solvent component and essence fragrance using ethyl alcohol]
[Comparative Example 4]
[Production of water-soluble fragrance composition using polyhydric alcohol] (Test according to [0042] Production Example 1 of Patent Document 6)
Dissolve 4.5 g of Ryoto-polyglycerin ester M-7D, HLB16.0, which is decaglycerin myristic acid ester, as an emulsifier in 12 g of ion-exchanged water at 43 ° C., and glycerin, which is a polyhydric alcohol instead of 95% ethyl alcohol V (mixed by Miyoshi Oil & Fats Co., Ltd.) 78 g was mixed, 4 g of orange essential oil was added, and the mixture was stirred at 8000 rpm for 10 minutes at 25 ° C. 100 g of a fragrance composition was obtained.

  Since glycerin, which is a polyhydric alcohol used in Comparative Example 4, is easy to stabilize the emulsified state, the water-soluble fragrance composition obtained in Comparative Example 4 becomes a uniform emulsion. For this reason, the cooling and standing, oil separation, and filtration steps of the manufacturing process (Table 1) of the essence flavor of Example 1 were not performed. And not the essence fragrance | flavor but the water-soluble fragrance | flavor composition was obtained.

[Comparison of the water-soluble fragrance composition using the polyhydric alcohol of the example of Patent Document 6 and the essence fragrance of the present invention]
[Manufacture of test solution]
The essence fragrance produced in Example 1 and the water-soluble fragrance composition obtained in Comparative Example 4 were added to a tea beverage having the composition shown in Table 7 so that the concentration would be 0.1%. Manufacturing.

[sensory evaluation]

When the transmittance | permeability of these black tea test liquids was measured by the method similar to Test Example 1, both showed the value of 99.7%. Therefore, it was found that the essence fragrance of Example 1, which is the product of the present invention, was very transparent and uniformly dissolved in black tea beverages and was stable over time.

[Example 9-3]
[Solution evaluation immediately after addition of essence fragrance using emulsifier of the present invention by jam and after storage]
0.1% of an essence flavor using the emulsifier obtained in Example 1 was added to the jam shown in Table 8 and mixed to obtain a jam test product. This test specimen was stored at 40 ° C. for 2 weeks to obtain a test specimen. When the two specimens were visually compared, no difference in turbidity could be confirmed. Regarding the transmittance, the jam shown in Table 8 was solid, and it was impossible to measure because the orange turbid juice was used as a raw material. However, the essence flavor of Example 1 of the present invention was not jammed. It was found that it was uniformly dissolved and stable over time.

[Example 9-4]
[Evaluation of Solubility Immediately after Addition of Essence Fragrance Using Emulsifier of the Present Invention and after Storage by Jelly]
To the jelly shown in Table 9, 0.1% of the essence flavor using the emulsifier obtained in Example 1 was added and mixed to obtain a jelly test product. Further, since this test sample melts at a high temperature, the test sample was obtained by storing at 5 ° C., which is an actual proper storage temperature, for 2 weeks. When the two specimens were visually compared, no difference in turbidity could be confirmed. Regarding the transmittance, it was impossible to measure because the jelly shown in Table 9 was solid and the orange turbid juice was used as a raw material, but the essence flavor of Example 1 of the present invention was changed to jelly. It was found that it was uniformly dissolved and stable over time.

  From the results of Example 9, the product of the present invention is uniformly dissolved in beverages and foods such as soft drinks, tea beverages, jellies, jams, and is stable over time regardless of processing conditions and storage conditions. I understand that.
