[0009] The beverage according to the present invention has an enhanced pleasant sour aftertaste. The method for producing a beverage according to the present invention can produce a beverage with an enhanced pleasant aftertaste of sourness. The method for enhancing the flavor of a beverage according to the present invention can enhance the pleasant lingering sourness of the beverage. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a description will be given of an embodiment (present embodiment) for carrying out a beverage, a method for producing a beverage, and a method for enhancing the flavor of a 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. Beverages according to this embodiment include, in the case of alcoholic beverages (with an alcohol content of 1% or more), for example, chuhai-flavored beverages, wine-flavored beverages, and beer-flavored beverages, and in the case of non-alcoholic beverages (with an alcohol content of less than 1%), for example, carbonated beverages (such as chuhai-flavored non-alcoholic beverages), fruit drinks, sports drinks, tea-based beverages, coffee, and dairy drinks. Here, a chuhai-flavored beverage is a beverage that tastes like chuhai, that is, a beverage designed to have the flavor and aroma 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 designed to have the flavor and aroma of wine. Each element constituting the beverage according to this embodiment will be described below.

[0012] (Sothoron) Sotolon (CAS number: 28664-35-9) is a compound with the chemical formula CHO, also known as 3-hydroxy-4,5-dimethylfuran-2(5H)-one. Sotolon is known as an off-flavor in the beverage industry due to its curry-like odor. The present inventors have surprisingly found that by adding sotolon and furaneol, which will be described later, to a beverage together (in other words, by adding two components known as off-flavors), the "pleasant lingering sourness" can be enhanced. The inventors also discovered that sotolon and furaneol have the effect of reducing the harshness of sharp acidity, enhancing the fruity juicy taste, enhancing the caramel-like sweet aroma, and enhancing the sourness reminiscent of citrus fruits.

[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, or 0.50 ppm or more. By ensuring that the sotolon content is equal to or greater than the specified value, the pleasant lingering sourness can be enhanced. Furthermore, by ensuring that the sotolon content is equal to or greater than the specified value, the sharpness of the sourness can be reduced, and the fruity, juicy flavor, caramel-like sweet aroma, and citrus-like sourness can be enhanced. The content of sotolon 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, or 1.00 ppm or less. By keeping the content of sotolon at a predetermined value or less, each effect can be fully exerted and it is possible to avoid a situation where the unique flavor of sotolon spoils the overall flavor balance. In this specification, the unit "ppm" is synonymous with "mg / L."

[0014] (Furaneol) Furaneol (CAS number: 3658-77-3) is a compound with the chemical formula CHO and is also known as 4-hydroxy-2,5-dimethyl-3(2H)-furanone. Furaneol exhibits a pungent aroma when present in large amounts, and is therefore sometimes considered an off-flavor in beverages. Furaneol exists as an isomer (R-isomer, S-isomer), and unless otherwise noted, the term is used to include both. As described above, the inventors have discovered that by incorporating furaneol and sotolon together into a beverage, not only is the effect of enhancing the pleasant aftertaste of sourness exerted, but also the effects of reducing the harshness of the sharp sourness, enhancing the fruity, juicy taste, enhancing the caramel-like sweet aroma, and enhancing the sourness reminiscent of citrus fruits are exerted.

[0015] The furaneol content 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, or 1.00 ppm or more. By having a furaneol content equal to or greater than a predetermined value, the following effects are exhibited: enhancing the pleasant lingering sourness, reducing the harshness of the sharp sourness, enhancing the fruity juicy flavor, enhancing the caramel-like sweet aroma, and enhancing the sourness reminiscent of citrus fruits. The furaneol content 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, or 2.50 ppm or less. By keeping the furaneol content at a specified value or less, each effect can be fully exerted, and it is possible to avoid a situation in which the unique flavor of furaneol spoils the overall flavor balance.

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

[0017] (acidity) The acidity (citric acid equivalent) 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, or 0.70 g / 100 mL or more. By having an acidity equal to or greater than a predetermined value, a certain level of sourness is imparted to the beverage, and the effects of the two components mentioned above, such as "enhancing the pleasant aftertaste of sourness," "reducing the harshness of sourness," and "citrus-like sourness," 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, or 0.80 g / 100 mL or less. By keeping the acidity at a specified value or less, the balance of flavor and aroma as a beverage can be improved.

[0018] The acidity (citric acid equivalent value) in this specification can be calculated by the method specified in JAS1075:2023 "Fruit drinks." The acidity can be adjusted by adding an acidulant as described below.

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

[0020] The beverage according to this embodiment may have the following sweetener content (converted to sucrose): The sweetener content, in terms of sucrose, is preferably 1.00 w / v% or more, 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, or 2.52 w / v% or more. The sweetener content, calculated as sucrose, is preferably 6.00 w / v% or less, more preferably 5.00 w / v% or less, 4.00 w / v% or less, 3.50 w / v% or less, or 3.00 w / v% or less. By ensuring that the sweetener content is within the specified range, the effects of the two components described above can be fully exerted, while providing the beverage with a sweetness that is suitable for the beverage.

[0021] The sucrose-equivalent sweetener content in a beverage is the sweetener content in the beverage converted to sucrose content. Specifically, the sucrose-equivalent sweetener content can be calculated by multiplying the sweetener content by the sweetness of the sweetener divided by the sweetness of sucrose (1). For example, in the case of a beverage containing 1 w / v% acesulfame potassium, the sucrose-equivalent sweetener content is calculated by multiplying the acesulfame potassium content (1 w / v%) by 200 / 1 (= sweetness of acesulfame potassium divided by the sweetness of sucrose), or 200 w / v%.

[0022] The sweetness of each sweetener can be determined using values ​​such as: high fructose corn syrup: 1, high fructose corn syrup: 0.80, fructose: 1.50, glucose: 0.75, galactose: 0.32, sucrose: 1, maltose: 0.33, lactose: 0.16, acesulfame potassium: 200, neotame: 10,000, sucralose: 600, saccharin sodium: 500, and stevia: 250. The sweetness of oligosaccharides can be measured using the following values: fructooligosaccharide: 0.45, galactooligosaccharide: 0.20, xylooligosaccharide: 0.45, lactoferrin: 0.60, raffinose: 0.20, isomaltooligosaccharide: 0.30, and soybean oligosaccharide: 0.70. The sweetness of sugar alcohols can be measured using the following values: sorbitol: 0.65, mannitol: 0.60, maltitol: 0.85, xylitol: 0.60, reduced palatinose: 0.45, and erythritol: 0.75. The content of sweeteners 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) may be any drinkable type, and is not limited by its type, production method, raw materials, etc., as long as the effects of the present invention are not impaired. Examples of ethanol that can be used include whiskey, brandy, spirits (e.g., spirits such as gin, vodka, and rum, and raw material alcohols), liqueurs, shochu, and even brewed alcoholic beverages such as sake, fruit wine, and beer.

[0024] (Alcohol content) The alcohol content (alcohol content) of the beverage according to this embodiment is not particularly limited, but may be, for example, 0% (v / v%), less than 1% (greater than 0% but less than 1%), 1% or more, 2% or more, 3% or more, 15% or less, 10% or less, 9% or less, 8% or less, or 7% or less. The alcohol content of the beverage according to this embodiment can be measured, for example, based on the National Tax Agency's prescribed analytical method (instruction) 3 Sake 3-4 Alcohol Content (Vibration Density Meter Method).

[0025] (foaming) The beverage according to this embodiment may be a sparkling beverage containing carbon dioxide, or may not be a sparkling beverage. Here, in the present embodiment, the term "foamable" refers to a foam having a gas pressure (total pressure) of 0.5 kg / cm at 20°C. 2 For example, 1.0 kg / cm 2 More than 1.5kg / cm 2 More than 2.0kg / cm 2 More than 2.2kg / cm 2 and above, and 5.0 kg / cm 2 Below, 4.0kg / cm 2 Below 3.5kg / cm 2 Below, 3.0kg / cm 2 The following is the result. The gas pressure of the beverage according to this embodiment can be measured based on, for example, National Tax Agency Specified Analysis Method (Instruction) 8-3 Gas Pressure.

[0026] (extract) The extract components of the beverage according to this embodiment are not particularly limited, but are 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, 2.00 w / v% or less.

[0027] The term "extract" refers to the non-volatile components contained in a beverage, and the extract content is the number of grams of non-volatile components contained in 100 cubic centimeters of original volume at a temperature of 15°C (Article 3 of the Liquor Tax Act). 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 method prescribed by the National Tax Agency of Japan.

[0028] (others) The beverage according to this embodiment may contain, or of course may not contain, antioxidants, flavorings, acidulants, salts, dietary fiber, and the like (hereinafter referred to as "additives") typically used in beverages, provided that the desired effects of the present invention are not impaired. Examples of antioxidants that can be used include vitamin C, vitamin E, and polyphenols. Examples of acidulants that can be used include citric acid, adipic acid, trisodium citrate, gluconodeltalactone, 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, and phosphoric acid. Examples of salts that can be used include table salt, acid potassium phosphate, acid calcium phosphate, ammonium phosphate, calcium sulfate, potassium metabisulfite, calcium chloride, potassium nitrate, ammonium sulfate, etc. Examples of dietary fibers that can be used include indigestible dextrin, pectin, polydextrose, and guar gum hydrolyzate. The above-mentioned raw materials may be commercially available. As for sotolon and furaneol, the individual components (pure substances) may be used, or extracts or mixtures containing the individual components may be used.

[0029] If the beverage according to this embodiment is to be a chuhai-flavored beverage, it may contain fruit flavors (flavors that impart a fruit-like aroma), fruit juice, fruit extracts (extracts obtained by extracting the active ingredients of fruit from fruit or fruit juice using water, alcohol, etc.), or fruit puree (semi-liquid products obtained by mashing or straining cooked or fresh fruit). Examples of fruit juice that can be used include concentrated fruit juice, reconstituted fruit juice, straight fruit juice, semi-clear fruit juice, clear fruit juice, and cloudy fruit juice, as well as diluted solutions, concentrated solutions, and mixtures thereof. The fruit from which the fruit juice, fruit extract, or fruit puree is derived may contain the peel. In addition, examples of the types of fruit (fruit species) include citrus fruits such as lemon, lime, mandarin orange, orange, grapefruit, yuzu, and Shikuwasa, and Rosaceae fruits such as plum, apple, strawberry, peach, cherry, plum, and pear, as well as conventionally known fruits such as grape, pomegranate, blueberry, black currant, cranberry, maqui berry, mango, pineapple, and kiwi.

[0030] The beverage according to this embodiment does not have to contain fruit juice, but if it does contain fruit juice, the content of the fruit juice is, for example, 0.50% or more, 0.80% or more, 1.00% or more, and 8.00% or less, 6.00% or less, 5.00% or less, 4.00% or less, or 3.00% or less. The fruit juice content can be calculated as follows: "Content (converted to fruit juice ratio) % (specifically w / w%)" = "Amount of fruit juice (g) in 100g of beverage" x "Concentration ratio" / 100g x 100. Here, the "concentration ratio" (relative concentration ratio of fruit juice when straight fruit juice is taken as 100%) is calculated in accordance with JAS standards, excluding sugar refractometer readings for sugars, honey, etc. added to fruit juice.

[0031] (Packaged beverages) The beverage according to the present embodiment can be provided in various containers. By filling the beverage in various containers, deterioration of the quality of the beverage due to long-term storage can be suitably prevented. The container may be any container that can be sealed, and so-called cans and barrels made of metal (such as aluminum or steel) can be used. Also, glass containers, PET bottles, paper containers, pouch containers, etc. can be used. The capacity of the container is not particularly limited, and any container currently in circulation can be used. It is preferable to use a metal container, as it completely blocks gas, moisture, and light and can maintain stable quality at room temperature for a long period of time.

[0032] As described above, the beverage according to this embodiment has an enhanced pleasant sour aftertaste. Furthermore, the beverage according to this embodiment has a reduced sharp sourness, and has an enhanced fruity juicy flavor, a caramel-like sweet aroma, and a citrus-like sourness.

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

[0034] In the mixing step, water, sotolon, furaneol, ethanol, additives, etc. are appropriately charged into a mixing tank to produce a mixed liquid. In this mixing step, the raw materials are mixed and adjusted so that the sotolon content, the furaneol content, etc. fall within the above-mentioned predetermined ranges.

[0035] In the post-treatment step, for example, filtration, sterilization, addition of carbon dioxide gas, and filling into a container are selectively carried out as needed. The filtration process in the post-processing step can be carried out using a general filter or strainer. Furthermore, the sterilization process in the post-processing step is preferably carried out by plate sterilization from the viewpoint of processing speed, etc., but is not limited to this and can be applied as long as a similar process can be performed. Furthermore, the filling process in the post-processing step is preferably carried out in a clean room maintained at a level of cleanliness that is normally achieved in the production of beverages. The order of each process in the post-processing step is not particularly limited.

[0036] The processes carried out in the mixing step and post-processing step can be carried out using equipment that is generally used to produce RTD (ready to drink) beverages and the like.

[0037] As described above, the method for producing a beverage according to this embodiment can produce a beverage with an enhanced, pleasant aftertaste of sourness. Furthermore, the beverage manufacturing method according to this embodiment can produce a beverage that has a reduced sharp sour taste and an enhanced fruity, juicy taste, a caramel-like sweet aroma, and a sour taste reminiscent of citrus fruits.

[0038] [Method for improving the flavor of beverages] Next, the beverage flavor enhancing method according to this embodiment will be described. The method for enhancing the flavor of a beverage according to this embodiment is a method for enhancing the lingering pleasant sourness of a beverage, and is a method for incorporating sotolon and furaneol. The contents of each component are the same as those described above for "drinks."

[0039] As described above, the beverage flavor enhancing method according to this embodiment can enhance the pleasant aftertaste of sourness. Furthermore, according to the method for improving the flavor of a beverage of this embodiment, it is possible to reduce the sharp sourness and enhance the juicy fruity taste, the sweet caramel-like aroma, and the sourness reminiscent of citrus fruits. [Example]

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

[0041] [Sample preparation] Each sample in Tables 1 and 2 was prepared by appropriately mixing vodka, furaneol, sotolon, high-intensity sweetener (a mixture of acesulfame potassium and sucralose in a certain ratio), citric acid, fruit juice (lemon juice), carbonated water, and pure water to obtain the amounts shown in the table. Sample 7-1 in Table 2 differs from the other samples in that it was prepared by further blending a fragrance (not containing furaneol or sotolon). The gas pressure (total pressure) at 20°C for each sample in Tables 1 and 2 is 2.2 kg / cm 2 It was decided.

[0042] [Exam Contents] For each sample produced by the above method, eight trained panelists with discriminatory abilities rated each sample on a 5-point scale from 1 to 5 according to the following evaluation criteria: "sharp sour edge," "juicy fruity taste," "sweet caramel-like aroma," "citrus-like sourness," and "pleasant sour aftertaste," and calculated the average score. All evaluations were made by drinking the samples.

[0043] (A sharp, sour edge: Evaluation criteria) The evaluation of the sharpness of the sourness was based on a 5-point scale for Sample 1-1, with 1 point for "no sharpness," 2 points for "a slight sharpness," 3 points for "a sharpness," 4 points for "a slightly strong sharpness," and 5 points for "a strong sharpness." The sharpness of the sourness is reduced as the score is lower, and can be judged to be preferable.

[0044] Here, "a sharp sour taste" refers to a taste that causes a stinging sensation when the sample is placed in the mouth and is felt to be unpleasant on the tongue or in the mouth. If the sour taste is sharp and sharp, the score is high, and if the sour taste is smooth and not sharp, the score is low.

[0045] (Fruit-like juicy taste: Evaluation criteria) The evaluation of the fruit-like juicy taste was based on a standard of 1 point for Sample 1-1, with 1 point for "no fruit-like juicy taste", 2 points for "a slight fruit-like juicy taste", 3 points for "a fruit-like juicy taste", 4 points for "a slightly strong fruit-like juicy taste", and 5 points for "a strong fruit-like juicy taste". The higher the score, the more enhanced the fruit-like juicy taste is, and it can be judged as being preferable.

[0046] Regarding the "juicy fruit-like taste," if the juiciness felt when eating fruit is strong, the score is high, and if not, the score is low.

[0047] (Caramel-like sweet aroma: Evaluation criteria) The evaluation of the caramel-like sweet aroma was based on a standard score of 1 for Sample 1-1, with 1 point for "no caramel-like sweet aroma", 2 points for "a slight caramel-like sweet aroma", 3 points for "a caramel-like sweet aroma", 4 points for "a slightly strong caramel-like sweet aroma", and 5 points for "a strong caramel-like sweet aroma". The higher the score, the stronger the caramel-like sweet aroma is, and the more preferable it is judged to be.

[0048] Here, the "sweet caramel-like aroma" is determined based on the aroma 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 the sourness reminiscent of citrus fruits was based on a standard score of 1 for Sample 1-1, with 1 point for "no sourness reminiscent of citrus fruits", 2 points for "a slight sourness reminiscent of citrus fruits", 3 points for "a sourness reminiscent of citrus fruits", 4 points for "a slightly strong sourness reminiscent of citrus fruits", and 5 points for "a strong sourness reminiscent of citrus fruits". The higher the score, the stronger the sourness reminiscent of citrus fruits, and the more preferable it can be judged to be.

[0050] Here, "citrus-like sourness" refers to the sourness that includes both taste and aroma, and the stronger the sourness that is reminiscent of citrus fruits is perceived, the higher the score.

[0051] (A pleasant sour aftertaste: Evaluation criteria) The evaluation of the pleasant sour aftertaste was based on a standard of 1 point for Sample 1-1, with 1 point for "no pleasant sour aftertaste", 2 points for "a slight pleasant sour aftertaste", 3 points for "a pleasant sour aftertaste", 4 points for "a slightly strong pleasant sour aftertaste", and 5 points for "a strong pleasant sour aftertaste". The pleasant sour aftertaste is judged to be more preferable as the score increases.

[0052] Here, "pleasant sour aftertaste" means exactly what it says, and the stronger the pleasant sourness felt in the aftertaste, the higher the score.

[0053] The table below shows the content of each component in the samples and the results of each evaluation. The numerical values ​​and indexes for each component shown in the table are the content and index in the final product.
