Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the technology described in Patent Document 1 did not specifically examine red grape flavor and did not focus on improving the red grape-likeness. Furthermore, conventional red grape-flavored beverages, such as those described in Patent Documents 2 and 3, had room for improvement in that, while they improved the red grape-likeness, they also made the acidity and astringency more pronounced. [Means for solving the problem]

[0006] According to the present invention, the following technologies relating to grape-flavored beverages are provided.

[0007] [1] A red grape-flavored beverage with a 4-propylphenol concentration of 5 to 20,000 ppb. [2] A red grape-flavored beverage as described in [1], having a sweetness level of 5 or less. [3] A red grape flavored beverage as described in [1] or [2], having a fruit juice content (straight juice equivalent) of 5% by mass or less. [4] A red grape-flavored beverage containing grape flavor, as described in any one of [1] to [3]. [5] A sugar-free red grape flavored beverage as described in any one of [1] through [4]. [6] A red grape flavored beverage containing a sweetener, as described in any one of [1] to [5]. [7] A carbonated beverage, a red grape flavored beverage as described in any one of [1] through [6]. [8] A non-alcoholic beverage, a red grape flavored beverage as described in any one of [1] through [7]. [9] A bottled red grape-flavored beverage as described in any one of [1] through [8]. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a beverage that can improve the balance between the characteristics of red grapes, the intensity of acidity, and the intensity of astringency. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described in detail below. In this specification, unless otherwise specified, the notation "a to b" in the description of numerical ranges means a or greater and b or less.

[0010] In this specification, "red grape-likeness" means that when drinking the beverage, one will perceive a well-balanced combination of the characteristic rich sweetness, natural astringency, and mellow acidity that one would feel when eating red grapes, resulting in an aroma and flavor close to that of fresh red grapes, and is distinct from the aroma and flavor of alcoholic red grape-flavored beverages such as wine.

[0011] <Red grape flavored beverage> The grape-flavored beverage of this embodiment has a 4-propylphenol concentration of 5 to 20,000 ppb. This improves the balance between the characteristics of red grapes and the intensity of acidity and astringency. Although the details of why this is the case are not clear, it is thought that the balance of sweetness, astringency, and acidity perceived when 4-propylphenol is consumed as a beverage is close to the balance of sweetness, astringency, and acidity of red grapes, so combining a specific amount of 4-propylphenol with red grape flavor can improve the characteristics of red grapes. In addition, it is speculated that the acidity and astringency from a specific amount of 4-propylphenol are compatible with red grapes, resulting in a stronger perception of acidity and astringency.

[0012] The following describes each component contained in the red grape-flavored beverage of this embodiment (hereinafter also simply referred to as "beverage").

[0013] [4-Propylphenol] 4-Propylphenol is a substance with CAS number 645-56-7.

[0014] The beverage in this embodiment has a 4-propylphenol concentration of 5 to 20,000 ppb. This improves the balance between the characteristics of red grapes, the intensity of acidity, and the intensity of astringency. In addition, 4-propylphenol is preferably 10 ppb or more in terms of improving the aroma, sourness, and astringency, more preferably 50 ppb or more in terms of further improving the aroma and sourness intensity, and may be 150 ppb or more in terms of further obtaining the sourness intensity and astringency intensity. Also, 4-propylphenol is preferably 15000 ppb or less, more preferably 10000 ppb or less, and even more preferably 8000 ppb or less, and still more preferably 5000 ppb or less in terms of improving the balance of the strawberry-like flavor, aroma, sourness, and astringency and obtaining deliciousness.

[0015] 4-Propylphenol may be used alone or as a mixture, and may also be contained in natural juices or the like. However, when using juices other than strawberry juice, the concentration of juices other than strawberry juice shall not impair the strawberry flavor of the present embodiment.

[0016] The concentration of 4-propylphenol in the beverage is determined by the solid-phase microextraction method (SPME) using a gas chromatograph mass spectrometer.

[0017] [Strawberry flavor] The strawberry flavor of the beverage of the present embodiment is obtained by using one or more selected from strawberry juice and grape flavors.

[0018] The variety of strawberries used for strawberry juice is not particularly limited. For example, one or more selected from Concord, Kyoho, Koshun, Pione, Campbell Early, Delaware, Muscat Berry A, Steuben, Akamine, Fujiminori, Ruby Red, Cabernet Sauvignon, etc. can be mentioned. All of them are preferably varieties with red, purple or black skin color and red or purple juice in appearance.

[0019] Also, the red grape juice as a raw material may be any of the squeezed juice of grape fruits (straight juice), concentrated juice obtained by concentrating the squeezed juice, and reduced juice obtained by further diluting the concentrated juice. Further, the red grape juice may be clear juice or cloudy juice clarified by a microfiltration method, an enzyme treatment method, an ultrafiltration method, or the like.

[0020] The grape flavor may be any that exhibits a red grape-like aroma, and known ones can be used. For example, those containing aroma components such as methyl N-methylanthranilate and 2-phenylethyl alcohol can be mentioned.

[0021] [Juice content rate] The juice content rate (in terms of straight juice; mass%) of the beverage of the present embodiment is preferably 5 mass% or less, more preferably 4 mass% or less, still more preferably 3 mass% or less, and further preferably 2 mass% or less, 1 mass% or less, 0.5 mass% or less, and 0.0 mass% in this order. By setting the juice content rate to be not more than the above upper limit value, it is possible to improve the red grape-like flavor while having low juice or no juice.

[0022] Note that the juice content rate is the relative concentration when the Brix value or acidity of the squeezed juice (straight juice) of the juice obtained by squeezing the juice and not subjected to treatment such as concentration is set to 100%. Whether the juice content rate is calculated based on the Brix value or the acidity is determined for each type of juice based on the JAS standard. Also, when converting the juice content rate of the juice based on the Brix value of the JAS standard, it is calculated excluding the Brix value of sugars, honey, etc. added to the juice. For example, for grapes, since the Brix value of the JAS standard is 11, when 10 mass% of concentrated grape juice with a Brix value of 55 is blended in the beverage, it becomes a beverage with a juice content rate of 50 mass%.

[0023] [[ID=二十一]] In this embodiment, the fruit juice may include not only red grape juice, but also white grape juice and fruit juices other than grape juice. Examples of fruit juices other than grape juice include orange juice, mandarin orange juice, grapefruit juice, lemon juice, lime juice, pear juice, apple juice, peach juice, strawberry juice, banana juice, mango juice, and the like. The fruit juice contained in the beverage of this embodiment is preferably red grape juice, and the proportion (mass%) of red grape juice to the total fruit juice is preferably 50% by mass or more, more preferably 60% by mass or more, even more preferably 70% by mass or more, and even more preferably 80% by mass or more, 90% by mass or more, 98% by mass or more, and 100% by mass, in that order.

[0024] [Other ingredients] The beverage of this embodiment may contain other ingredients besides those mentioned above, as long as the effects of the present invention are achieved. Specifically, it may contain ingredients commonly used in beverages, such as sweeteners, acidulants, flavorings (excluding grape flavor), vitamins, colorings, antioxidants, emulsifiers, preservatives, seasonings, extracts, pH adjusters, quality stabilizers, and thickeners.

[0025] (sweetener) Examples of the sweeteners mentioned above include sugars such as fructose, sucrose, glucose, granulated sugar, lactose, fructose-glucose syrup, and maltose; sugar alcohols; low-intensity sweeteners such as xylitol and D-sorbitol; and high-intensity sweeteners such as thaumatin, stevia extract, disodium glycyrrhizinate, acesulfame potassium, sucralose, aspartame, saccharin, neotame, and sodium saccharin. These may be used individually or in combination of two or more.

[0026] However, the beverage of this embodiment may be sugar-free. That is, the sugar content may be less than 0.5% by mass / volume. This allows for a better balance of red grape characteristics, acidity, and astringency, while meeting the needs of consumers who wish to reduce their sugar intake.

[0027] (Acidulant) Examples of the above-mentioned acidulants include citric acid, lactic acid, adipic acid, gluconic acid, succinic acid, tartaric acid, fumaric acid, malic acid, phytic acid, ascorbic acid, acetic acid, and phosphoric acid, as well as their salts. These may be used individually or in combination of two or more.

[0028] The following are examples of optional combinations of ingredients included in the beverage of this embodiment. However, the beverage of this embodiment is not limited to the following examples. (i) A red grape-flavored beverage consisting only of 4-propylphenol at 5-20,000 ppb, water, and grape flavor. (ii) A red grape-flavored beverage consisting only of 4-propylphenol at 5-20,000 ppb, water, grape flavor, and carbon dioxide. (iii) A red grape flavored beverage consisting only of 4-propylphenol 5-20,000 ppb, water, grape flavor, sweetener, and carbon dioxide. (iv) A red grape flavored beverage consisting only of 4-propylphenol 5-20,000 ppb, water, grape flavoring, grape juice, and carbon dioxide.

[0029] The following describes the various characteristics of the beverage according to this embodiment.

[0030] [Sweetness level] The beverage of this embodiment preferably has a sweetness level of 5 or less, more preferably 4 or less, even more preferably 2 or less, and especially preferably 1 or less. This allows for the creation of a beverage that is low in sweetness and sugar, yet enhances the characteristics of red grapes.

[0031] The level of sweetness can be adjusted, for example, by using the aforementioned sweeteners, fruit juice, and other various ingredients.

[0032] The sweetness level is a parameter that indicates the strength of the sweetness of each sweetener compared to sucrose. For example, values ​​listed in "Comprehensive Guide to Sweeteners" (Japan Sugar Refiners Association, May 1990), "All About High-Sweetness Sweetener Sucralose" (Korin Co., Ltd., May 2003), and "Beverage Terminology Dictionary" (Beverage Japan Co., Ltd., June 25, 1999) can be used. If there is a range in the listed sweetness levels, the median value should be used. For example, the sweetness levels of typical sweeteners are 1 for sucrose, 0.65 for glucose, 1.5 for fructose, 600 for sucralose, 200 for acesulfame potassium, and 200 for aspartame.

[0033] [Sugar content (Brix value)] The sugar content (Brix value) of the beverage (at 20°C) in this embodiment can be set appropriately according to the palatability of the beverage, but for example, it is preferably 5 or less, more preferably 4 or less, and even more preferably in the order of 2 or less, 1 or less, 0.9 or less, 0.7 or less, and 0.5 or less.

[0034] The sugar content (Brix value) can be measured, for example, by using a digital refractometer Rx-5000α (manufactured by Atago Corporation) to determine the reading of a sugar refractometer at 20°C. The sugar content can be adjusted, for example, by the amount of the sweeteners, fruit juice, and other various ingredients mentioned above.

[0035] [acidity] The acidity of the beverage in this embodiment is preferably 0.5 g / 100 ml or less, more preferably 0.3 g / 100 ml or less, and even more preferably 0.1 g / 100 ml or less. By keeping the acidity within the above numerical range, it is possible to improve the balance between the characteristics of red grapes, the intensity of acidity, and the intensity of astringency, while maintaining a good level of deliciousness.

[0036] Acidity can be expressed as the amount of acid contained in 100 ml converted to citric acid in grams (anhydrous citric acid g / 100 ml). Acidity can also be measured using the method specified in the JAS standard for acidity measurement, specifically the neutralization titration method (quantitative formula) using a 0.1 mol / L sodium hydroxide standard solution as the alkaline solution.

[0037] [pH] The pH of the beverage in this embodiment at 20°C is preferably 2.4 or higher, more preferably 2.7 or higher, and even more preferably 3.0 or higher. On the other hand, the pH is preferably 7.6 or lower, more preferably 7.0 or lower, and even more preferably 4.0 or lower if it contains acid. By keeping the pH within the above range, it is possible to improve the balance between the characteristics of red grapes, the intensity of acidity, and the intensity of astringency, while maintaining a good level of deliciousness.

[0038] pH can be measured using a commercially available pH meter. pH can be adjusted, for example, by changing the amount of acidulant or by using a pH adjuster.

[0039] [Carbon dioxide, alcohol] Furthermore, the beverage in this embodiment may be a carbonated beverage containing carbon dioxide. The carbon dioxide pressure of the beverage (at 20°C) is preferably 1.5 to 5.5 gas volumes, and more preferably 3.5 to 5.0 gas volumes. The method for incorporating carbon dioxide into a beverage is not particularly limited and can be appropriately determined by those skilled in the art. In the case of carbonated beverages, the physical properties such as pH should be the values ​​for the beverage excluding carbon dioxide.

[0040] Furthermore, the beverage in this embodiment is preferably a non-alcoholic beverage. A non-alcoholic beverage is a beverage that substantially does not contain alcohol, and specifically means a beverage in which the alcohol content, such as ethanol, is less than 1.0 volume / vol%.

[0041] [container] The containers used for beverages in this embodiment include sealed containers made of glass, paper, plastic (such as polyethylene terephthalate), aluminum, and steel, either as a single material or a composite or laminated material thereof. The type of container is not particularly limited, but examples include PET bottles, aluminum cans, steel cans, paper cartons, chilled cups, and glass bottles. From the viewpoint of allowing the beverage to be visually inspected, PET bottles are preferred.

[0042] While there are no particular limitations on the volume of the beverage, 100 to 2000 ml is preferred, and 100 to 500 ml is even more preferred because it is easier to finish drinking it.

[0043] There are no particular limitations on the method of heat sterilization of packaged beverages, but in Japan, heat sterilization is carried out in accordance with the provisions of the Food Sanitation Act. Specifically, this includes a method of sterilizing at high temperature for a short time and then filling it into a storage container that has been sterilized under sterile conditions (UHT sterilization method), and a retort sterilization method in which the prepared liquid is filled into a storage container such as a can and then subjected to retort treatment.

[0044] [Drinking method] The beverage in this embodiment is preferably one that can be consumed as is without dilution. In particular, it is preferable that it be a so-called ready-to-drink (RTD) beverage that can be consumed immediately after opening the container.

[0045] [Serving temperature] The beverage in this embodiment is preferably intended for use at room temperature or cold. Cold beverages are those whose liquid temperature is lower than room temperature, specifically those cooled to approximately 4-15°C.

[0046] The embodiments of the present invention have been described above, but these are merely examples, and various other configurations can also be adopted. [Examples]

[0047] The present invention will be described below with reference to examples and comparative examples, but the present invention is not limited thereto.
