Specific Description of the Invention

[0008] In the present invention, the term "beer-flavored non-alcoholic beverage" refers to a beverage with a beer-like flavor, and is used to include both beverages that contain no alcohol at all, i.e., beverages with an ethanol concentration of 0.00 v / v%, and beverages with an ethanol concentration of more than 0.00 v / v% and less than 1 v / v%. Beer-flavored non-alcoholic beverages include fermented beer-flavored non-alcoholic beverages and non-fermented beer-flavored non-alcoholic beverages. Fermented beer-flavored non-alcoholic beverages refer to beer-flavored non-alcoholic beverages that have undergone a fermentation process using yeast, and include beverages produced by removing the alcoholic components generated during the fermentation process after the fermentation process (sometimes referred to as "de-alcoholized beverages" in this specification), as well as beverages produced by terminating the fermentation process when the ethanol concentration is less than 1 v / v%. Non-fermented beer-flavored non-alcoholic beverages refer to beverages produced without undergoing a fermentation process.

[0009] In the non-alcoholic beer-taste beverage of the present invention, the upper limit value (hereinafter or less) of the alcohol (ethanol) concentration is 0.99% (v / v), 0.98% (v / v), 0.97% (v / v), 0.96% (v / v), 0.95% (v / v), 0.94% (v / v), 0.93% (v / v), 0.92% (v / v), 0.91% (v / v), 0.90% (v / v), 0.89% (v / v), 0.88% (v / v), 0.87% (v / v), 0.86% (v / v), 0.85% (v / v), 0.84% (v / v), 0.83% (v / v), 0.82% (v / v), 0.81% (v / v), 0.80% (v / v), 0.79% (v / v), 0.78% (v / v), 0.77% (v / v), 0.76% (v / v), 0.75% (v / v), 0.74% (v / v), 0.73% (v / v), 0.72% (v / v), 0.71% (v / v), 0.70% (v / v), 0.69% (v / v), 0.68% (v / v), 0.67% (v / v), 0.66% (v / v), 0.65% (v / v), 0.64% (v / v), 0.63% (v / v), 0.62% (v / v), 0.61% (v / v), 0.60% (v / v), 0.59% (v / v), 0.58% (v / v), 0.57% (v / v), 0.56% (v / v), 0.55% (v / v), 0.54% (v / v), 0.53% (v / v), 0.52% (v / v), 0.51% (v / v), 0.50% (v / v), 0.49% (v / v), 0.48% (v / v), 0.47% (v / v), 0.46% (v / v), 0.45% (v / v), 0.44% (v / v), 0.43% (v / v), 0.42% (v / v), 0.41% (v / v), 0.40% (v / v), 0.39% (v / v), 0.38% (v / v), 0.37% (v / v), 0.36% (v / v), 0.35% (v / v), 0.34% (v / v), 0.33% (v / v), 0.32% (v / v), 0.31% (v / v), 0.30% (v / v), 0.29% (v / v), 0.28% (v / v), 0.27% (v / v), 0.26% (v / v), 0.25% (v / v), 0.24% (v / v), 0.23% (v / v), 0.22% (v / v), 0.21% (v / v), 0.20% (v / v), 0.19% (v / v), 0.18% (v / v), 0.17% (v / v), 0.16% (v / v), 0.15% (v / v),0.14% (v / v), 0.13% (v / v), 0.12% (v / v), 0.11% (v / v), 0.10% (v / v), 0.09% (v / v), 0.08% (v / v), 0.07% (v / v), 0.0 6% (v / v), 0.05% (v / v), 0.04% (v / v), 0.03% (v / v), 0.02% (v / v), 0.01% (v / v), 0.009% (v / v), 0.008% (v / v), 0.00 The upper limit may be 0.001% (v / v), 0.002% (v / v), 0.003% (v / v), or 0.004% (v / v), and the lower limit (not less than or exceeding) may be 0.001% (v / v), 0.002% (v / v), 0.003% (v / v), or 0.004% (v / v). These upper and lower limits may also be combined in any manner.

[0010] In the present invention, the alcohol concentration (ethanol concentration) of a beverage can be measured by gas chromatography (GC) with an FID detector. In this case, for more accurate concentration measurement, it is desirable to use a calibration curve created based on the measured values ​​of several control samples with known concentrations. It is preferable that these control samples with known concentrations are in the same range as the concentration to be measured. It is also preferable to use an internal standard, such as 2-propanol.

[0011] The beer-taste non-alcoholic beverage of the present invention uses malt as at least a portion of its raw material, and preferably uses at least one or both of barley malt and wheat malt as the barley-derived raw material. In the present invention, the proportion of barley malt (by mass) in the raw material malt (by mass) can be, for example, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, or 100%, and the proportion of wheat malt (by mass) in the raw material malt (by mass) can be, for example, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, or 100%. It should be noted that the present invention can also use extracted malt (i.e., malt extract). In the above, "or more" can be interpreted as "exceeding."

[0012] The beer-flavored non-alcoholic beverage of the present invention can achieve a rich flavor and a harmonious aftertaste regardless of the malt usage ratio. However, the malt usage ratio may be, for example, 10% or less, 10% or more, 15% or less, 15% or more, 20% or less, 20% or more, 21% or less, 21% or more, 22% or less, 22% or more, 23% or less, 23% or more, 24% or less, 24% or more, 25% or less, 25% or more, 30% or less, 30% or more, 31% or less, 31% or more, 32% or less, 32% or more, 33% or less, 33% or more, 34% or less, 34% or more, 35% or less, 35% or more, The malt content can be 40% or less, 40% or more, 45% or less, 45% or more, 50% or less, 50% or more, 55% or less, 55% or more, 60% or less, 60% or more, 65% or less, 65% or more, 66% or less, 66% or more, 67% or less, 67% or more, 68% or less, 68% or more, 69% or less, 69% or more, 70% or less, 70% or more, 75% or less, 75% or more, 80% or less, 80% or more, 85% or less, 85% or more, 90% or less, 90% or more, 95% or less, 95% or more, or 100%. "Less than" can mean "less than," and "greater than" can mean "greater than." These upper and lower limits can be combined arbitrarily. In the present invention, "malt usage ratio" refers to the ratio of the mass of malt to the mass of all raw materials excluding hops and water.

[0013] In the beer-taste non-alcoholic beverage of the present invention, in addition to malt, ungerminated wheat species such as ungerminated barley (including extracts) and ungerminated wheat (including extracts) can also be used as raw materials.

[0016] In the present invention, the concentration of 2-pentylfuran in a beverage can be measured by GC / MS analysis, for example, by separating aroma components in a beverage using a C18 solid-phase column and subjecting the resulting analytical sample to GC / MS, as shown in the Examples below.

[0017] The beer-flavored non-alcoholic beverage of the present invention is characterized by having a well-balanced flavor and aftertaste despite being a non-alcoholic beverage. Beer-flavored non-alcoholic beverages have had problems with insufficient flavor and aftertaste balance due to the fact that they are non-alcoholic and the unique methods used to prepare them to be non-alcoholic. In particular, in dealcoholized beverages in which alcohol is removed after the fermentation process, components that contribute to flavor and aftertaste balance may be lost during the production process. The beer-flavored non-alcoholic beverage of the present invention has a well-balanced flavor and aftertaste balance, thereby solving the above-mentioned problems of beer-flavored non-alcoholic beverages. Here, "flavor" refers to the flavor sensation perceived as a broad flavor, complexity, full-bodiedness, etc. Furthermore, "aftertaste balance" refers to the flavor sensations of sourness, astringency, and astringency that are perceived as sour when sipped.

[0018] There are no limitations on the method for producing the beer-taste non-alcoholic beverage of the present invention, so long as the 2-pentylfuran is contained in a concentration within the specified range.

[0019] When the production of the fermented beer-flavored non-alcoholic beverage of the present invention includes a step of removing alcoholic components produced during the fermentation process, the concentration can be adjusted by adding 2-pentylfuran after alcohol removal (dealcoholization) so that the concentration falls within a predetermined range. In the present invention, methods for removing alcohol after the fermentation process include, for example, (i) a method of removing alcohol by distillation under reduced pressure or normal pressure, (ii) a method of removing alcohol by adsorbing volatile components into steam using centrifugal force, and (iii) a method of removing alcohol using a reverse osmosis (RO) membrane, and the method can be selected from any of the above (i), (ii), and (iii), or any of the above (i) and (ii).

[0020] Furthermore, when the fermentation process for the fermented beer-taste non-alcoholic beverage of the present invention is stopped at a stage when the ethanol concentration is less than 1 v / v %, the concentration can be adjusted by adding 2-pentylfuran at any stage in the production process so that the concentration falls within a predetermined concentration range, as long as the adjustment is after a step in which 2-pentylfuran may volatilize (e.g., a boiling step).

[0021] The fermented, beer-flavored, non-alcoholic beverage of the present invention can be produced according to a typical production procedure for a fermented, beer-flavored, non-alcoholic beverage, except for adjusting the 2-pentylfuran concentration as described above. The fermented, beer-flavored, non-alcoholic beverage of the present invention can be produced, for example, by preparing a brewing liquid from malt, hops, water, and other ingredients, removing solids from the brewing liquid by leaving it to stand, and then fermenting and filtering the brewing liquid. The other ingredients may be used as ingredients for the brewing liquid, or may be blended with the prepared brewing liquid.

[0022] The preparation of the brewing liquid can be carried out according to a conventional method, for example, by sequentially carrying out the following steps: (a) saccharifying a mixture of water and raw materials containing malt, followed by filtering to obtain wort; (b) adding hops to the obtained wort and then boiling the wort; and (c) cooling the boiled wort.

[0023] In the present invention, degradation treatment can be performed by adding protease, carbohydrate-degrading enzyme, or cellulolytic enzyme individually or in combination at any time before the completion of the fermentation process (for example, during mashing, fermentation, or both mashing and fermentation). Examples of protease include protease preparations, examples of carbohydrate-degrading enzymes include enzymes derived from brewing raw materials such as malt, and commercially available enzyme preparations (α-amylase, β-amylase, glucoamylase, α-glucosidase, pullulanase, isoamylase, etc.), and examples of cellulolytic enzymes include commercially available enzyme preparations (β-glucanase, xylanase, hemicellulase, etc.).

[0024] In the present invention, in the saccharification process, malt with high endoprotease activity and / or an enzyme preparation having endoprotease activity can be used to promote proteolysis, and malt with low endoprotease activity can be used to inhibit proteolysis.

[0025] In the present invention, the saccharification temperature can be, for example, 30° C. to 100° C., 35° C. to 100° C., 40° C. to 100° C., or 60° C. to 80° C. The saccharification time can be appropriately set taking into account the saccharification temperature, and can be, for example, 30 minutes to 180 minutes, 50 minutes to 150 minutes, 60 minutes to 140 minutes, or 30 minutes to 100 minutes.

[0026] In the present invention, the boiling temperature can be, for example, 100° C. to 150° C., 100° C. to 140° C., 100° C. to 130° C., or 90° C. to 100° C. The boiling time can be appropriately set in consideration of the boiling temperature, and can be, for example, 10 minutes to 180 minutes, 20 minutes to 150 minutes, 30 minutes to 120 minutes, or 30 minutes to 90 minutes.

[0027] In the present invention, the fermentation conditions are not particularly limited, and the fermentation can be carried out according to a conventional method.

[0028] In the non-fermented, beer-taste non-alcoholic beverage of the present invention, the concentration of 2-pentylfuran can be adjusted to a predetermined concentration range by adding 2-pentylfuran at any stage in the production process, as long as the adjustment is after a step in which 2-pentylfuran may be lost by volatilization (for example, a boiling step).

[0029] The beer-flavored non-alcoholic beverage of the present invention may further contain ethyl caprylate (CAS RN: 106-32-1) and / or ethyl caproate (CAS RN: 123-66-0). In the present invention, the concentration of ethyl caprylate and / or ethyl caproate can be adjusted by selecting raw materials or production conditions. Non-limiting examples of such raw materials and production conditions include brewing conditions, selection of yeast (including strain), adjustment of the amount of yeast used, adjustment of fermentation conditions, and selection and amount of filter aid used. Furthermore, the concentration of ethyl caprylate and / or ethyl caproate can be adjusted by adding them at any stage of the production process.

[0030] In the beer-taste non-alcoholic beverage of the present invention, the lower limit of the ethyl caprylate concentration (not less than or exceeding) is not limited, and may be, for example, 0.001 ppm, 0.002 ppm, 0.003 ppm, 0.004 ppm, 0.005 ppm, 0.006 ppm, 0.007 ppm, 0.008 ppm, 0.009 ppm, 0.010 ppm, 0.011 ppm, 0.012 ppm, 0.013 ppm, 0.014 ppm, 0.015 ppm, 0.016 ppm, 0.017 ppm, 0.018 ppm, 0.019 ppm, 0.020 ppm, or ppm, 0.021ppm, 0.022ppm, 0.023ppm, 0.024ppm, 0.025ppm, 0.026ppm, 0.0 27ppm, 0.028ppm, 0.029ppm, 0.030ppm, 0.031ppm, 0.032ppm, 0.033ppm, 0 .. 034ppm, 0.035ppm, 0.036ppm, 0.037ppm, 0.038ppm, 0.039ppm, 0.040ppm, 0.041ppm, 0.042ppm, 0.043ppm, 0.044ppm, 0.045ppm, 0.046ppm, 0.047ppm m, 0.048ppm, 0.049ppm, 0.050ppm, 0.051ppm, 0.052ppm, 0.053ppm, 0.054 ppm, 0.055ppm, 0.056ppm, 0.057ppm, 0.058ppm, 0.059ppm, 0.060ppm, 0.0 61ppm, 0.062ppm, 0.063ppm, 0.064ppm, 0.065ppm, 0.066ppm, 0.067ppm, 0 .068ppm, 0.069ppm, 0.070ppm, 0.071ppm, 0.072ppm, 0.073ppm, 0.074ppm , 0.075 ppm, 0.076 ppm, 0.077 ppm, 0.078 ppm, 0.079 ppm, 0.080 ppm, 0.081 ppm, 0.082 ppm, 0.083 ppm, 0.084 ppm, 0.085 ppm, 0.086 ppm, 0.087 ppm, 0.088 ppm, 0.089 ppm, 0.090 ppm, 0.091 ppm, 0.092 ppm, 0.093 ppm, 0.094 ppm, 0.095 ppm, 0.096 ppm, 0.097 ppm, 0.098 ppm, 0.099 ppm or 0.10 ppm.The upper limit (or less than) of the ethyl caprylate concentration in the beer-taste non-alcoholic beverage of the present invention is not particularly limited as long as the effects of the present invention are achieved.

[0052] Example 1: Production and evaluation of beer-flavored non-alcoholic beverages In Example 1, evaluation tests were carried out on each test sample of the beer-flavored non-alcoholic beverage (test plots 1 to 27).

[0053] (1) Method A. Production of a Beer-Taste Non-Alcoholic Beverage Barley malt, enzymes, and warm water were placed in a mash tank and saccharified at a temperature of 67°C to 78°C. The saccharified liquid was filtered and transferred to a boiling kiln, where hops were added and boiled. Subsequently, the malt residue was removed by filtration to obtain wort. Hops were added to the obtained wort and boiled, followed by solid-liquid separation and cooling to obtain a clear wort. Yeast was added, and the fermentation temperature and fermentation time were adjusted. The resulting fermented liquid was filtered to produce a fermented malt beverage. Next, carbon dioxide was removed by spraying it into a degassing tank, and the fermented liquid was heated to around 50°C. The alcohol was then removed by contact with steam heated to around 50°C in a vacuum column at around 60 mbar, and carbon dioxide was added to obtain a beer-taste non-alcoholic beverage (malt usage ratio 100%) with an alcohol concentration of less than 0.005 v / v% (Test Group 1). Test plots 2 to 27 were obtained by adding 2-pentylfuran, ethyl caprylate and / or ethyl caproate to the beer-flavored non-alcoholic beverage of Test plot 1 to adjust the concentrations shown in Table 3.

[0054] B. Evaluation Test An evaluation test was conducted on test plots 1 to 27 by five trained panelists. Specifically, two evaluation items, "depth of flavor" and "harmony of aftertaste," were rated on a scale of 1 to 4 in increments of 0.5, and the average evaluation scores of the five panelists were calculated. Here, "depth of flavor" refers to the flavor sensation recognized by the breadth of flavor, complexity, and body imparted, etc. "Harmony of aftertaste" refers to the flavor sensation of sourness, astringency, and astringency that are recognized as sour when held in the mouth. The specific rating criteria are as shown below, and test plots 2 to 27 were evaluated based on the rating of test plot 1. <Criteria for each rating> 1: Approximately the same as test plot 1 2: A slight improvement can be recognized by consecutive comparisons with test plot 1 3: An improvement can be recognized by consecutive comparisons with test plot 1 4: An improvement can be recognized without comparing with test plot 1

[0055] (2) Results The results are shown in Table 3. The results of Test Plots 2 to 6 indicated that the addition of 2-pentylfuran (single addition) improved the flavor depth and harmony of the aftertaste. Furthermore, the results of Test Plots 17 to 21 indicated that the addition of 2-pentylfuran and ethyl caprylate in combination (two-component addition) improved the flavor depth and harmony of the aftertaste compared to the addition of 2-pentylfuran alone. Furthermore, the results of Test Plots 22 to 26 indicated that the addition of 2-pentylfuran and ethyl caproate in combination (two-component addition) improved the flavor depth and harmony of the aftertaste compared to the addition of 2-pentylfuran alone. Furthermore, the results of Test Plot 27 indicated that the addition of 2-pentylfuran, ethyl caprylate, and ethyl caproate to a concentration of 0.0001 ppm (triple addition) improved the flavor depth and harmony of the aftertaste compared to the addition of each compound alone to the same concentration (Test Plots 2, 7, and 12).
