Description

[Technical Field]

[0001] The present invention relates to a beverage, a method for producing a beverage, and a method for improving the flavor of a beverage. [Background technology]

[0002] In order to meet the diverse tastes of consumers, many types of beverages and methods of manufacturing them have been proposed to date.

[0003] For example, Patent Document 1 proposes a beverage characterized by containing 1 to 750 ppm of acetic acid and 5 to 2500 ppm of ethyl maltol. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2018-153123 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] The invention described in Patent Document 1 focuses on acetic acid and ethyl maltol and specifies their respective content in order to improve the initial aroma of a beverage and to achieve an excellent balance of sweetness and acidity.

[0006] On the other hand, the inventors wanted to differentiate their beverage from others by adding and enhancing a distinctive flavor. They focused on the "aftertaste" (the flavor felt at the end of drinking), which greatly influences the impression of a beverage, and wanted to enhance the "pleasant aftertaste of acidity."

[0007] Therefore, the object of the present invention is to provide a beverage with an enhanced pleasant sour aftertaste, a method for producing the beverage, and a method for improving the flavor of the beverage. [Means for solving the problem]

[0008] The aforementioned problem can be solved by the following means. (1) A beverage containing sotolon and furaneol. (2) The beverage described in 1 above, which contains ethanol. (3) The beverage according to claim 1 or claim 2, wherein the sotolon content is 0.25 to 8.00 ppm. (4) The beverage according to any one of the above 1 to 3, wherein the furaneol content is 0.50 to 8.00 ppm. (5) A beverage according to any one of the above 1 to 4, wherein the acidity is 0.20 to 2.00 g / 100 mL. (6) A method for producing a beverage, comprising a step of adding sotolon and furaneol. (7) A method for enhancing the flavor of a beverage, which enhances the pleasant acidity of the aftertaste, comprising the step of adding sotolon and furaneol. [Effects of the Invention]

[0009] The beverage according to the present invention has an enhanced pleasant lingering acidity. The method for producing beverages according to the present invention can produce beverages in which a pleasant, lingering sourness is enhanced. The method for improving the flavor of beverages according to the present invention can enhance the pleasant lingering acidity of the beverage. [Modes for carrying out the invention]

[0010] The following describes the embodiment of the beverage, the method for producing the beverage, and the method for improving the flavor of the beverage according to the present invention.

[0011] [Beverage] The beverage according to this embodiment is a beverage containing sotolon and furaneol, and may further contain ethanol. In this embodiment, examples of beverages include alcoholic beverages (with an alcohol content of 1% or more), such as chuhai-flavored beverages, wine-flavored beverages, and beer-flavored beverages, and examples of non-alcoholic beverages (with an alcohol content of less than 1%), such as carbonated beverages (such as chuhai-flavored non-alcoholic beverages), fruit drinks, sports drinks, tea-based beverages, coffee, and dairy beverages. Here, a "chuhai-flavored beverage" is a beverage that tastes like chuhai, that is, a beverage whose flavor is designed to evoke the aroma and taste of chuhai. Note that the flavor of chuhai also includes the flavors of sours and cocktails. A "wine-flavored beverage" is a beverage that tastes like wine, that is, a beverage whose flavor is designed to evoke the aroma and taste of wine. The following describes each element that constitutes the beverage according to this embodiment.

[0012] (Sotron) Sotolon (CAS number: 28664-35-9) is a compound with the chemical formula C6H8O3, also known as 3-hydroxy-4,5-dimethylfuran-2(5H)-one. Sotolon is known in the beverage industry as an off-flavor due to its curry-like odor. The inventors have discovered that by including sotolon and furaneol (described later) together in a beverage (in other words, by including two components known as off-flavors), it is possible to surprisingly enhance the "pleasant sour aftertaste." Furthermore, the inventors have discovered that sotolon and furaneol exhibit the effects of reducing the harshness of the acidity, enhancing the fruity, juicy flavor, enhancing the caramel-like sweet aroma, and enhancing the citrus-like acidity.

[0013] The sotolon content is preferably 0.25 ppm or more, more preferably 0.30 ppm or more, 0.35 ppm or more, 0.40 ppm or more, 0.45 ppm or more, 0.50 ppm or more. By having the sotolon content be a predetermined value or more, a pleasant sour aftertaste can be enhanced. Further, by having the sotolon content be a predetermined value or more, an effect of reducing the sharpness of the sourness, an effect of enhancing a juicy fruit-like flavor, an effect of enhancing a caramel-like sweet aroma, and an effect of enhancing a sourness reminiscent of citrus are exhibited. The sotolon content is preferably 8.00 ppm or less, more preferably 7.00 ppm or less, 6.00 ppm or less, 5.50 ppm or less, 5.00 ppm or less, 4.00 ppm or less, 3.00 ppm or less, 2.00 ppm or less, 1.00 ppm or less. By having the sotolon content be a predetermined value or less, each effect can be firmly exhibited, and a situation where the overall flavor balance is deteriorated due to the unique flavor of sotolon can be avoided. In this specification, the unit "ppm" is synonymous with "mg / L".

[0014] (Furaneol) Furaneol (CAS No.: 3658-77-3) is a compound represented by the chemical formula C6H8O3 and is also called 4-hydroxy-2,5-dimethyl-3(2H)-furanone. And, furaneol may be judged as an off-flavor in the beverage field because it exhibits a pungent aroma when the content is high. Note that furaneol has isomers (R-form, S-form), and is used in the sense of including these unless otherwise specified. As described above, the inventors have found that by containing this furaneol and sotolon together in a beverage, not only an effect of enhancing a pleasant sour aftertaste is exhibited, but also an effect of reducing the sharpness of the sourness, an effect of enhancing a juicy fruit-like flavor, an effect of enhancing a caramel-like sweet aroma, and an effect of enhancing a sourness reminiscent of citrus are exhibited.

[0015] The content of furaneol is preferably 0.50 ppm or more, more preferably 0.60 ppm or more, 0.70 ppm or more, 0.80 ppm or more, 0.90 ppm or more, and 1.00 ppm or more. When the content of furaneol is at a predetermined value or more, an effect of enhancing the pleasant aftertaste of acidity, an effect of reducing the sharpness of acidity, an effect of enhancing the juicy taste similar to fruit, an effect of enhancing the caramel-like sweet aroma, and an effect of enhancing the sourness reminiscent of citrus are exhibited. The content of furaneol is preferably 8.00 ppm or less, more preferably 6.00 ppm or less, 5.50 ppm or less, 5.00 ppm or less, 3.50 ppm or less, 3.00 ppm or less, and 2.50 ppm or less. When the content of furaneol is at a predetermined value or less, each effect is firmly exhibited, and a situation where the overall flavor balance deteriorates due to the unique flavor of furaneol can be avoided.

[0016] The contents of sotolon and furaneol in the beverage can be measured, for example, by solvent extraction-gas chromatography-mass spectrometry (LLE-GC-MS method).

[0017] (Acidity) The acidity (acidity in terms of citric acid) of the beverage according to this embodiment is as follows. The acidity is preferably 0.20 g / 100 mL or more, more preferably 0.30 g / 100 mL or more, 0.40 g / 100 mL or more, 0.50 g / 100 mL or more, 0.60 g / 100 mL or more, and 0.70 g / 100 mL or more. When the acidity is at a predetermined value or more, a certain acidity is imparted to the beverage, and the "effect of enhancing the pleasant aftertaste of acidity", "effect of reducing the sharpness of acidity", and "sourness reminiscent of citrus" based on the above two components are more clearly exhibited. The acidity is preferably 2.00 g / 100 mL or less, more preferably 1.50 g / 100 mL or less, 1.20 g / 100 mL or less, 1.00 g / 100 mL or less, and 0.80 g / 100 mL or less. When the acidity is at a predetermined value or less, the flavor balance of the beverage can be made better.

[0018] The acidity (citric acid equivalent) in this specification can be calculated using the method specified in JAS 1075:2023 for "fruit beverages". The acidity can be adjusted using the acidulants described below.

[0019] (sweetener) Sweeteners are substances used to impart sweetness. Examples of sweeteners include high-intensity sweeteners such as acesulfame potassium, neotame, sucralose, saccharin, sodium saccharin, disodium glycyrrhizinate, stevia, glycyrrhizin, thaumatin, monellin, aspartame, and alitame; isomerized sugars such as high-fructose corn syrup and glucose-fructose syrup; monosaccharides such as fructose, glucose, and galactose; disaccharides such as sucrose, maltose, and lactose; and also oligosaccharides and sugar alcohols. However, the beverage according to this embodiment preferably contains a high-intensity sweetener among sweeteners.

[0020] The beverage according to this embodiment may have the following sweetener content (in sucrose equivalent): The sweetener content is preferably 1.00 w / v% or more in terms of sucrose, and more preferably 1.20 w / v% or more, 1.42 w / v% or more, 1.50 w / v% or more, 2.00 w / v% or more, 2.50 w / v% or more, and 2.52 w / v% or more. The sweetener content is preferably 6.00 w / v% or less in terms of sucrose, and more preferably 5.00 w / v% or less, 4.00 w / v% or less, 3.50 w / v% or less, and 3.00 w / v% or less. By keeping the sweetener content within a predetermined range, the effects of the two components mentioned above can be fully realized while providing a sweetness suitable for the beverage.

[0021] The sucrose equivalent content of sweeteners in a beverage refers to the amount of sweetener in the beverage converted to its sucrose equivalent. Specifically, the sucrose equivalent content of a sweetener can be calculated by multiplying the "sweetener content" by the "sweetness level of the sweetener / sweetness level of sucrose (1)". For example, in the case of a beverage containing 1 w / v% acesulfame potassium, the sucrose equivalent content of the sweetener is "200 w / v%", which is obtained by multiplying the acesulfame potassium content of "1 w / v%" by "200 / 1" (= sweetness level of acesulfame potassium / sweetness level of sucrose).

[0022] For the sweetness level of each sweetener, you can use values ​​such as: fructose-glucose liquid sugar: 1, glucose-fructose liquid sugar: 0.80, fructose: 1.50, glucose: 0.75, galactose: 0.32, sucrose: 1, maltose: 0.33, lactose: 0.16, acesulfame potassium: 200, neotame: 10000, sucralose: 600, sodium saccharin: 500, and stevia: 250. Furthermore, for the sweetness of oligosaccharides, the following values ​​can be used: fructooligosaccharide: 0.45, galactooligosaccharide: 0.20, xylooligosaccharide: 0.45, lactulose oligosaccharide: 0.60, raffinose: 0.20, isomaltoligosaccharide: 0.30, and soybean oligosaccharide: 0.70. For the sweetness of sugar alcohols, the following values ​​can be used: sorbitol: 0.65, mannitol: 0.60, maltitol: 0.85, xylitol: 0.60, reduced palatinose: 0.45, and erythritol: 0.75. In addition, the sweetener content in beverages can be measured using high-performance liquid chromatography (HPLC).

[0023] (ethanol) The beverage according to this embodiment may or may not contain ethanol. Ethanol (so-called alcohol) can be any that can be consumed, and as long as the effects of the present invention are not inhibited, it is not limited by type, production method, raw materials, etc. However, whiskey, brandy, spirits (such as spirits like gin, vodka, rum, etc., and raw material alcohol, etc.), liqueurs, shochu, etc., and furthermore, fermented liquors such as sake, fruit wine, beer, etc. can be used.

[0024] (Alcohol content) Although the alcohol content (alcohol percentage) of the beverage according to the present embodiment is not particularly limited, for example, it may be 0% (v / v%), less than 1% (more than 0% and less than 1%), 1% or more, 2% or more, 3% or more, or may be 15% or less, 10% or less, 9% or less, 8% or less, 7% or less. Incidentally, the alcohol content of the beverage according to the present embodiment can be measured, for example, based on the National Tax Agency's specified analysis method (ordinance) 3 sake 3-4 alcohol content (vibrating densitometer method).

[0025] (Foaming property) The beverage according to the present embodiment may or may not be foaming and contain carbon dioxide gas. Here, the foaming property in the present embodiment means that the gas pressure (total pressure) at 20 °C is 0.5 kg / cm 2 or more, for example, 1.0 kg / cm 2 or more, 1.5 kg / cm 2 or more, 2.0 kg / cm 2 or more, 2.2 kg / cm 2 or more, and also 5.0 kg / cm 2 or less, 4.0 kg / cm 2 or less, 3.5 kg / cm 2 or less, 3.0 kg / cm 2 or less. Incidentally, the gas pressure of the beverage according to the present embodiment can be measured, for example, based on the National Tax Agency's specified analysis method (ordinance) 8-3 gas pressure.

[0026] (Extract content) The extract content of the beverage according to this embodiment is not particularly limited, but is as follows. The extract content is, for example, 0.50 w / v% or more, 0.80 w / v% or more, 1.00 w / v% or more, 1.30 w / v% or more, and 5.00 w / v% or less, 4.00 w / v% or less, 3.00 w / v% or less, and 2.00 w / v% or less.

[0027] Furthermore, "extract" refers to the non-volatile components contained in a beverage, and "extract content" is the number of grams of non-volatile components contained in 100 cubic centimeters of the original volume at a temperature of 15 degrees Celsius (Article 3 of the Liquor Tax Law). The extract content of a beverage can be calculated, for example, by measuring the specific gravity (sake meter value) and alcohol content in accordance with the analytical methods prescribed by the National Tax Agency of Japan.

[0028] (others) The beverage according to this embodiment may contain antioxidants, flavorings, acidulants, salts, dietary fiber, etc. (hereinafter referred to as "additives" as appropriate), which are normally added to beverages, as long as the desired effects of the present invention are not inhibited, or it may not contain them. As antioxidants, for example, vitamin C, vitamin E, polyphenols, etc. can be used. As acidulants, for example, citric acid, adipic acid, trisodium citrate, glucono delta-lactone, gluconic acid, potassium gluconate, sodium gluconate, succinic acid, monosodium succinate, disodium succinate, sodium acetate, DL-tartaric acid, L-tartaric acid, sodium DL-tartrate, sodium L-tartrate, carbon dioxide, lactic acid, sodium lactate, fumaric acid, monosodium fumarate, DL-malic acid, sodium DL-malate, phosphoric acid, etc. can be used. Examples of salts that can be used include table salt, acidic potassium phosphate, acidic calcium phosphate, ammonium phosphate, calcium sulfate, potassium metabisulfite, calcium chloride, potassium nitrate, and ammonium sulfate. Examples of dietary fiber that can be used include indigestible dextrin, pectin, polydextrose, and guar gum hydrolysate. Furthermore, the aforementioned raw materials can be those that are generally available on the market. In addition, sotolon and furaneol may be used as individual components (each pure substance), or extracts or mixtures containing each component may be used.

[0029] In this embodiment, if the beverage is to be a chuhai-flavored beverage, it may also contain fruit flavor (flavor that imparts a fruit-like aroma), fruit juice, fruit extract (an extract obtained by extracting the active ingredients of fruit using water or alcohol, etc. from fruit or fruit juice), and fruit puree (a semi-liquid substance obtained by grinding or straining cooked fruit or raw fruit). As for the fruit juice, for example, various types of fruit juice such as concentrated fruit juice, reconstituted fruit juice, straight fruit juice, semi-clear fruit juice, transparent fruit juice, and cloudy fruit juice, as well as diluted solutions, concentrated solutions, and mixtures thereof, can be used. Furthermore, the fruit from which the fruit juice, fruit extract, and fruit puree are derived may include the fruit peel. Furthermore, the types of fruits (fruit species) include citrus fruits such as lemons, limes, mandarins, oranges, grapefruits, yuzu, and shikwasa, as well as fruits of the Rosaceae family such as plums, apples, strawberries, peaches, cherries, and pears. In addition to these, other conventionally known fruits such as grapes, pomegranates, blueberries, blackcurrants, cranberries, maqui berries, mangoes, pineapples, and kiwis can also be listed.

[0030] The beverage according to this embodiment does not have to contain fruit juice, but if it does contain fruit juice, the fruit juice content is, for example, 0.50% or more, 0.80% or more, 1.00% or more, 8.00% or less, 6.00% or less, 5.00% or less, 4.00% or less, and 3.00% or less. The fruit juice content can be calculated using the following formula: "Fruit juice content (converted to fruit juice percentage) % (specifically, w / w%)" = "Amount of fruit juice added to 100g of beverage (g)" × "Concentration ratio" / 100g × 100. Here, when calculating the "concentration ratio" (the relative concentration ratio of the fruit juice when straight fruit juice is considered 100%), the JAS standard shall be followed, and the refractometer readings for sugars such as sugars and honey added to the fruit juice shall be excluded.

[0031] (Packaged beverages) The beverage according to this embodiment can be provided in various containers. By filling the beverage into various containers, deterioration of quality due to long-term storage can be effectively prevented. Any airtight container is acceptable, and metal containers (such as aluminum or steel cans or barrels) can be used. Glass containers, PET bottles, paper containers, and pouch containers can also be used. There are no particular limitations on the container's capacity; any currently available containers can be used. However, metal containers are preferred because they completely block gas, moisture, and light, and maintain stable quality at room temperature for extended periods.

[0032] As described above, the beverage according to this embodiment has an enhanced pleasant aftertaste of acidity. Furthermore, the beverage according to this embodiment has a reduced harshness in the acidity, and an enhanced fruity, juicy flavor, a caramel-like sweet aroma, and a citrusy acidity.

[0033] [Beverage manufacturing method] Next, the method for producing the beverage according to this embodiment will be described. The method for producing a beverage according to this embodiment includes a mixing step and a post-processing step.

[0034] In the mixing process, water, sotolon, furaneol, ethanol, and additives are added to the mixing tank as needed to produce the mixed liquid. In this mixing process, the raw materials should be mixed and adjusted so that the content of sotolon, furaneol, etc., falls within the predetermined ranges mentioned above.

[0035] Then, in the post-processing stage, treatments such as filtration, sterilization, carbon dioxide addition, and filling into containers are selectively performed as needed. The filtration process in the post-processing stage can be carried out using a general filter or strainer. While plate sterilization is preferred for the sterilization process in the post-processing stage from the viewpoint of processing speed, other methods that can perform a similar process are acceptable and are not limited to this. Furthermore, the filling process in the post-processing stage is preferably carried out in a cleanroom maintaining a level of cleanliness typically used in beverage manufacturing. The order of each process in the post-processing stage is not particularly limited.

[0036] Furthermore, each process carried out in the mixing and post-processing stages can be performed using equipment commonly used for manufacturing RTD (ready-to-drink) beverages.

[0037] As described above, the beverage manufacturing method according to this embodiment makes it possible to produce a beverage with an enhanced pleasant sour aftertaste. Furthermore, according to the beverage manufacturing method of this embodiment, it is possible to produce a beverage in which the harshness of the acidity is reduced, and the fruity, juicy flavor, the caramel-like sweet aroma, and the citrusy acidity are enhanced.

[0038] [Methods for improving the flavor of beverages] Next, a method for improving the flavor of a beverage according to this embodiment will be described. The method for improving the flavor of a beverage according to this embodiment is a method for enhancing the pleasant acidity aftertaste of a beverage, and involves including sotolon and furaneol in the beverage. The content of each component is the same as the values ​​explained in the "Beverages" section above.

[0039] As described above, the method for improving the flavor of a beverage according to this embodiment can enhance the pleasant aftertaste of acidity. Furthermore, according to the method for improving the flavor of a beverage as described in this embodiment, it is possible to reduce the harshness of the acidity, while enhancing the juicy, fruity taste, the sweet, caramel-like aroma, and the citrusy acidity. [Examples]

[0040] Next, the present invention will be described by illustrating examples of embodiments that satisfy the requirements of the present invention and comparative examples that do not.

[0041] [Preparing the sample] For each sample in Tables 1 and 2, the following ingredients were prepared by appropriately mixing vodka, furaneol, sotolon, a high-intensity sweetener (a mixture of acesulfame potassium and sucralose in a specific ratio), citric acid, fruit juice (lemon juice), carbonated water, and purified water in the quantities shown in the table. Note that sample 7-1 in Table 2 differs from the other samples in that it was prepared by adding fragrance (without furaneol or sotolon). The gas pressure (total pressure) of each sample in Tables 1 and 2 at 20°C is 2.2 kg / cm². 2 That's what I decided.

[0042] [Exam Content] For each sample produced using the method described above, eight trained panelists with discriminatory abilities scored each of the following aspects on a 5-point scale from 1 to 5, according to the evaluation criteria below: "sharp acidity," "juicy, fruity flavor," "sweet, caramel-like aroma," "citrus-like acidity," and "pleasant lingering acidity." The average score was then calculated. All evaluations were based on tasting the samples.

[0043] (Sharp, sharp acidity: Evaluation criterion) The sharpness of the acidity was evaluated using Sample 1-1 as a baseline of 5 points. A score of 1 indicated "no sharpness of acidity," 2 points indicated "slight sharpness," 3 points indicated "sharpness," 4 points indicated "somewhat strong sharpness," and 5 points indicated "strong sharpness." A lower score indicates a reduced sharpness of acidity, which is considered preferable.

[0044] Here, "sharp, sharp acidity" refers to a stinging sensation that occurs when the sample is placed in the mouth, causing an unpleasant feeling on the tongue and in the mouth. A higher score is given when the acidity is sharp and sharp, while a lower score is given when the acidity is smooth and rounded.

[0045] (Fruity, juicy flavor: Evaluation criteria) The evaluation of the fruity, juicy flavor was based on a baseline of 1 point for Sample 1-1. A score of 1 indicated "no fruity, juicy flavor," 2 points indicated "slightly fruity, juicy flavor," 3 points indicated "fruity, juicy flavor," 4 points indicated "somewhat strong fruity, juicy flavor," and 5 points indicated "strong fruity, juicy flavor." A higher score indicates a greater enhancement of the fruity, juicy flavor, which is considered desirable.

[0046] Here, regarding the "juicy, fruity flavor," a higher score is given if the juiciness felt is strongly compared to eating fruit, and a lower score is given if it is not felt.

[0047] (Sweet caramel-like scent: Evaluation criteria) The evaluation of the caramel-like sweet scent was based on a baseline of 1 point for Sample 1-1. A score of 1 was given for "no caramel-like sweet scent," 2 points for "slightly noticeable caramel-like sweet scent," 3 points for "noticeable caramel-like sweet scent," 4 points for "somewhat strong caramel-like sweet scent," and 5 points for "strong caramel-like sweet scent." A higher score indicates a stronger and more desirable caramel-like sweet scent.

[0048] Here, "a sweet caramel-like aroma" refers to the scent perceived while drinking the sample, and is a caramel-like aroma that is perceived positively even when added to a beverage.

[0049] (Sourness reminiscent of citrus fruits: Evaluation criteria) The evaluation of citrus-like acidity was based on a baseline of 1 point for Sample 1-1. A score of 1 indicated "no citrus-like acidity," 2 points indicated "slight citrus-like acidity," 3 points indicated "citrus-like acidity," 4 points indicated "somewhat strong citrus-like acidity," and 5 points indicated "strong citrus-like acidity." A higher score indicates a stronger citrus-like acidity, which is considered more desirable.

[0050] Here, "a citrusy acidity" refers to the acidity encompassing both taste and aroma, and the stronger the citrusy acidity perceived, the higher the score.

[0051] (A pleasant lingering acidity: Evaluation criterion) The evaluation of the pleasant acidity aftertaste was based on a score of 1 for Sample 1-1, with 1 point being the baseline. A score of 1 indicated "no pleasant acidity aftertaste," 2 points indicated "a slight pleasant acidity aftertaste," 3 points indicated "a pleasant acidity aftertaste," 4 points indicated "a moderately strong pleasant acidity aftertaste," and 5 points indicated "a strong pleasant acidity aftertaste." A higher score indicates a stronger and more desirable pleasant acidity aftertaste.

[0052] Here, "a pleasant lingering acidity" means exactly what it says; the stronger the pleasant acidity felt in the aftertaste, the higher the score.

[0053] The table shows the content of each component in the sample, along with the results of each evaluation. The numerical values ​​and indicators for each component shown in the table represent the content and indicators in the final product.
