DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 flavor of a beverage according to the present invention.

[0011] [Beverage] The beverage according to this embodiment has a sodium content equal to or greater than a predetermined value, and has a glutamic acid content and a benzaldehyde content each equal to or greater than a predetermined value. Here, the beverage according to this embodiment is not limited to a specific type of beverage, but may be, for example, a chuhai-flavored beverage. A chuhai-flavored beverage is a beverage that tastes like chuhai, that is, a beverage that is flavored and designed to have the flavor of chuhai. Note that the flavor of chuhai also includes the flavors of sours and cocktails. In addition, since the beverage according to this embodiment has an enhanced mild salty taste, it is preferably a plum-flavored beverage that is particularly positively recognized for its mild salty taste. A plum-flavored beverage is a beverage that is flavored and designed to have a plum aroma. Examples of plum-flavored beverages include pickled plum flavored beverages and green plum flavored beverages. In addition, the beverage according to this embodiment may be a shiso flavored beverage. In addition, when the beverage according to this embodiment contains alcohol, it becomes a chuhai-flavored alcoholic beverage or a plum-flavored alcoholic beverage. Each element constituting the beverage according to this embodiment will be described below.

[0012] (Glutamic Acid) Glutamic acid is an amino acid with the chemical formula C5H9NO4. The present inventors have surprisingly found that by adding glutamic acid and benzaldehyde (described below) to a beverage (a beverage having a sodium content equal to or greater than a specified value), the "mild saltiness" and "flashy fruitiness" are enhanced. The present inventors have also discovered that by adding glutamic acid and benzaldehyde (described below) to a beverage, the "crisp umami flavor" and "authentic umeboshi flavor" can be enhanced. As shown in the results of the examples described below, it has been confirmed that the effects of either glutamic acid or benzaldehyde alone are not fully exerted, but that by containing both (when the content of each is equal to or greater than a specified value), each effect is fully exerted. In the present specification, glutamic acid means, strictly speaking, L-glutamic acid (CAS number: 56-86-0). Glutamic acid may be added to the beverage in the form of a salt such as monosodium glutamate, but the manner of addition is not particularly limited, and when fruit juice, fruit extract, yeast extract, or the like is used, glutamic acid may be contained in the beverage by adding these.

[0013] The content of glutamic acid is preferably 0.1 ppm or more, more preferably 0.5 ppm or more, 1.0 ppm or more, 3.0 ppm or more, 4.3 ppm or more, 7.0 ppm or more, 10.0 ppm or more, 15.0 ppm or more, 17.2 ppm or more, 20.0 ppm or more, 25.0 ppm or more, 30.0 ppm or more, 35.0 ppm or more, 38.0 ppm or more, 40.0 ppm or more, and more preferably 41.3 ppm or more. By having the glutamic acid content be equal to or more than a predetermined value, the mild saltiness and gorgeous fruitiness can be enhanced, and the sharp umami and authentic feeling of pickled plum can also be enhanced. The glutamic acid content is preferably 250.0 ppm or less, more preferably 220.0 ppm or less, 200.0 ppm or less, 180.0 ppm or less, 172.0 ppm or less, 150.0 ppm or less, 130.0 ppm or less, and more preferably 100.0 ppm or less. By keeping the glutamic acid content at a predetermined value or less, the beverage can have a well-balanced flavor. In this specification, the unit "ppm" is synonymous with "mg / L."

[0014] The glutamic acid content in a beverage can be measured, for example, by high performance liquid chromatography (HPLC).

[0015] In the beverage according to this embodiment, when glutamic acid is added as monosodium glutamate, the content of monosodium glutamate is, for example, as follows. The content of sodium glutamate is, for example, 1 ppm or more, 5 ppm or more, 18 ppm or more, 20 ppm or more, 30 ppm or more, 40 ppm or more, 50 ppm or more, and 280 ppm or less, 250 ppm or less, 220 ppm or less, 200 ppm or less, or 180 ppm or less.

[0016] (Benzaldehyde) Benzaldehyde (CAS number: 100-52-7) is a type of aromatic aldehyde with the chemical formula CHO. The present inventors have surprisingly found that by adding benzaldehyde and the above-mentioned glutamic acid to a beverage (a beverage having a sodium content of a predetermined value or more), the "mild saltiness" and "flashy fruitiness" are enhanced. The present inventors have also discovered that by adding benzaldehyde and the above-mentioned glutamic acid to a beverage, the "crisp umami flavor" and the "authentic taste of pickled plums" can be enhanced.

[0017] The benzaldehyde content is preferably 0.01 ppm or more, more preferably 0.05 ppm or more, 0.08 ppm or more, 0.1 ppm or more, 0.5 ppm or more, 0.8 ppm or more, or 1.0 ppm or more. By having the benzaldehyde content be a predetermined value or more, the mild saltiness and gorgeous fruitiness can be enhanced, and the sharp umami and authentic feeling of umeboshi can also be enhanced. The benzaldehyde content is preferably 30.0 ppm or less, more preferably 20.0 ppm or less, 12.0 ppm or less, 10.0 ppm or less, 8.0 ppm or less, 5.0 ppm or less, and more preferably 3.0 ppm or less. By keeping the benzaldehyde content at a predetermined value or less, the flavor of the beverage can be balanced.

[0018] The benzaldehyde content in a beverage can be measured, for example, by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS method).

[0019] (Benzaldehyde content / Glutamic acid content) When the glutamic acid content in the beverage is X ppm and the benzaldehyde content is Y ppm, Y / X is, for example, as follows: Y / X is preferably 0.01 or more, more preferably 0.015 or more, 0.018 or more, and even more preferably 0.02 or more. Y / X is preferably 0.50 or less, more preferably 0.40 or less, 0.30 or less, and even more preferably 0.23 or less. By ensuring that Y / X falls within the specified range, the effects of enhancing the mild saltiness, the vibrant fruitiness, the sharp umami, and the authentic taste of umeboshi can be more reliably achieved.

[0020] (sodium) The sodium content of the beverage according to this embodiment is as follows: The sodium content is preferably 10 mg / 100 mL or more, more preferably 20 mg / 100 mL or more, 30 mg / 100 mL or more, 40 mg / 100 mL or more, 45 mg / 100 mL or more, and more preferably 47 mg / 100 mL or more. By making the sodium content equal to or more than a predetermined value, the saltiness to be enhanced appears in the beverage, and the effect of enhancing the mild saltiness and the authentic taste of pickled plum can be more reliably exhibited. The sodium content is preferably 100 mg / 100 mL or less, more preferably 80 mg / 100 mL or less, 70 mg / 100 mL or less, 60 mg / 100 mL or less, and more preferably 55 mg / 100 mL or less. By keeping the sodium content at a predetermined value or less, the flavor of the beverage can be balanced.

[0021] The sodium content of a beverage can be measured, for example, by atomic absorption spectrometry. Furthermore, the salty taste of a beverage can appear even if it does not contain salt, if the sodium content is high.

[0022] (acidity) The acidity (acidity calculated as citric acid) of the beverage according to this embodiment is as follows. The acidity is preferably 0.1 g / 100 mL or more, more preferably 0.2 g / 100 mL or more, 0.3 g / 100 mL or more, 0.4 g / 100 mL or more, 0.45 g / 100 mL or more, and more preferably 0.49 g / 100 mL or more. By having an acidity of a predetermined value or more, the effect of enhancing the sharp umami taste can be more reliably exhibited. The acidity is preferably 2.0 g / 100 mL or less, more preferably 1.5 g / 100 mL or less, 1.0 g / 100 mL or less, 0.7 g / 100 mL or less, or 0.6 g / 100 mL or less. By keeping the acidity at a predetermined value or less, the flavor of the beverage can be balanced.

[0023] The acidity in this specification (acidity converted into citric acid: acidity value converted into citric acid equivalent) can be determined by the method specified in the Japanese Agricultural Standards for Fruit Drinks (Notification No. 489 of the Ministry of Agriculture, Forestry and Fisheries of February 24, 2016). The acidity can be adjusted by adding an acidulant as described below.

[0038] As described above, the method for producing a beverage according to this embodiment can produce a beverage with an enhanced mild saltiness and vibrant fruitiness. Furthermore, the method for producing a beverage according to this embodiment can produce a beverage with enhanced sharp umami flavor and the authentic flavor of pickled plum.

[0039] [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 adjusting the sodium content to a predetermined value or more, the glutamic acid content to a predetermined value or more, and the benzaldehyde content to a predetermined value or more. The contents of each component are the same as those explained in the "beverage" section above.

[0040] As described above, according to the method for enhancing beverage flavor of this embodiment, it is possible to enhance the mild saltiness and vibrant fruitiness of the beverage. Furthermore, according to the method for enhancing the flavor of a beverage according to this embodiment, it is possible to enhance the sharp umami taste and authentic flavor of pickled plums in the beverage. EXAMPLES

[0041] Next, the present invention will be described by way of examples which satisfy the requirements of the present invention and comparative examples which do not.

[0042] [Sample preparation] Each sample in Tables 1 and 2 was prepared by mixing vodka, sweetener (fructose glucose syrup), citric acid (anhydrous), trisodium citrate, sodium glutamate, benzaldehyde, carbonated water, and water in the amounts shown in the table. The gas pressure (total pressure) at 20°C for each sample in Tables 1 and 2 is 2.3 kg / cm 2 It was decided.

[0043] [Test Contents] For each sample produced by the above-mentioned method, five trained panelists with discriminatory abilities independently scored the following five items on a 5-point scale from 1 to 5 for "mild saltiness," "lively fruitiness," "crisp umami," "authentic umeboshi flavor," and "overall evaluation" in accordance with the following evaluation criteria, and the average of the scores was calculated. All evaluations were performed by drinking the samples.

[0044] (Mild saltiness: Evaluation criteria) The mild saltiness was evaluated based on a standard score of 1 for sample 1-1, with a score of 1 for "weak mild saltiness" and a score of 5 for "strong mild saltiness." The higher the score, the more enhanced the mild saltiness is, and the more preferable it can be judged to be. Here, "mild saltiness" refers to a saltiness that adds a nice accent to the flavor of a beverage and is well-rounded without any harshness, and is considered to be a particularly desirable flavor characteristic in plum-flavored (including pickled plum) beverages.

[0045] (Gorgeous fruitiness: Evaluation criteria) The evaluation of the fruity flavor was based on a standard of 1 point for sample 1-1, with 1 point for "weak fruity flavor" and 5 points for "strong fruity flavor." The higher the score, the more enhanced the fruity flavor is, and the more preferable it can be judged to be. Here, "flashy fruitiness" refers to the fruitiness that is reminiscent of sake, which is felt when drinking sake.

[0046] (Sharp umami flavor: Evaluation criteria) The evaluation of the sharp umami flavor was based on a standard of 1 point for sample 1-1, with 1 point for "weak sharp umami flavor" and 5 points for "strong sharp umami flavor." The higher the score, the more enhanced the sharp umami flavor is, and the more preferable it can be judged to be. Here, "crisp umami" refers to a full-bodied umami flavor that leaves a clean aftertaste (does not linger in the aftertaste), like dry sake.

[0047] (Authenticity of Umeboshi: Evaluation Criteria) The evaluation of the authenticity of the umeboshi was based on a standard of 1 point for sample 1-1, with 1 point for "weak authentic umeboshi flavor" and 5 points for "strong authentic umeboshi flavor." The higher the score, the more enhanced the authentic umeboshi flavor is, and the more preferable it can be judged to be. Here, the "authentic flavor of umeboshi" refers to a flavor that is reminiscent of the flesh of umeboshi, and is a flavor similar to the flesh of real pickled umeboshi.

[0048] (Overall rating: Rating criteria) For the overall evaluation, no benchmark score was set, with a score of 1 for a "poor overall evaluation as a beverage" and a score of 5 for a "good overall evaluation as a beverage."

[0049] Here, the "overall evaluation" is based on the balance of flavor as a beverage. For example, if the flavor balance is disrupted by a strong flavor based on a specific component, the beverage is rated as "poor."

[0050] The table below shows the content of each component in the samples and the results of each evaluation. The numerical values ​​and indices for each component shown in the table are the content and indices in the final product.

[0051] [Table 1]

[0052] [Table 2]

[0053] (Review of results) Table 1 shows the results of varying the glutamic acid content. From the results of Samples 1-1 to 1-3 in Table 1, it was confirmed that Sample 1-2, which was a beverage that only contained benzaldehyde, did not sufficiently achieve the desired effects (enhancing the mild saltiness, enhancing the vibrant fruitiness, enhancing the sharp umami taste, and enhancing the authentic flavor of umeboshi), whereas Sample 1-3, which contained both benzaldehyde and glutamic acid, fully achieved the desired effects (2.2 points or more for each evaluation item, with only the vibrant fruitiness being 2 points or more). Furthermore, from the results of Samples 1-3 to 1-6 in Table 1, it was confirmed that in beverages containing a predetermined amount of benzaldehyde, the desired effects were more strongly exerted as the glutamic acid content increased. When all the evaluations were taken into consideration, among samples 1-1 to 1-6, favorable results were obtained for samples 1-3 to 1-6, and in particular, samples 1-4 to 1-6 obtained very favorable results.

[0054] Table 2 shows the results of varying the benzaldehyde content. From the results of Samples 2-1 to 2-2 in Table 2 and Sample 1-1 in Table 1, it was confirmed that Sample 2-1, which was a beverage that only contained glutamic acid, did not sufficiently achieve the desired effects (enhancing the mild saltiness, enhancing the vibrant fruitiness, enhancing the crisp umami flavor, and enhancing the authentic flavor of umeboshi), whereas Sample 2-2, which contained both benzaldehyde and glutamic acid, fully achieved the desired effects (2.2 points or more for each evaluation item, with only the vibrant fruitiness being 2 points or more). Furthermore, from the results of Samples 2-2 to 2-5 in Table 2, it was confirmed that in beverages containing a predetermined amount of glutamic acid, the desired effects were more strongly exerted as the benzaldehyde content increased. When all the evaluations were taken into consideration, among samples 2-1 to 2-5, favorable results were obtained for samples 2-2 to 2-5, and in particular, samples 2-3 to 2-4 obtained very favorable results.
