[0010] Furthermore, the beer-taste beverage of one embodiment of the present invention may be a fermented beer-taste beverage that has undergone a fermentation process using yeast, or it may be a non-fermented beer-taste beverage that has not undergone a fermentation process. The fermented beer-taste beverage may be an ale beer-taste beverage brewed through a fermentation process using a top-fermenting yeast (Saccharomyces, etc.), a lager beer-taste beverage or a pilsner beer-taste beverage brewed through a fermentation process using a bottom-fermenting yeast (Saccharomyces, etc.), or a blend of these beer-taste beverages. The fermented beer-taste beverage may also be produced from a beer-taste concentrate that is a blend of a beer-taste concentrate brewed through a fermentation process using a top-fermenting yeast (for example, a fermented liquid after fermentation, such as a solution before being served as a beverage) and a beer-taste concentrate brewed through a fermentation process using a bottom-fermenting yeast. Furthermore, the "fermentation" referred to in this specification may be alcoholic fermentation, in which alcohol is produced, or non-alcoholic fermentation, in which alcohol is not produced. In addition, the beer-taste beverage of one embodiment of the present invention may be a malt-based beer-taste beverage that uses malt as an ingredient, or a malt-free beer-taste beverage that does not use malt. An example of a malt-based beer-taste beverage is a barley malt-based beer-taste beverage.

[0011] The beer-taste beverage of one embodiment of the present invention is a low-alcohol beer-taste beverage. In this specification, "low-alcohol" refers to a beer-taste beverage with an alcohol content (ethanol content) of 1.0 (v / v)% or more and 3.8 (v / v)% or less. From the perspective of providing a satisfying beer-taste beverage, the alcohol content of the beer-taste beverage of one embodiment of the present invention is preferably 1.1 (v / v)% or more, 1.2 (v / v)% or more, 1.3 (v / v)% or more, 1.4 (v / v)% or more, or 1.5 (v / v)% or more, and further preferably 1.6 (v / v)% or more, 1.7 (v / v)% or more, 1.8 (v / v)% or more, 1.9 (v / v)% or more, 2.0 (v / v)% or more, 2.5 (v / v)% or more, or 2.6 (v / v)% or more. It may be 0.1(v / v)% or more, 2.2(v / v)% or more, 2.3(v / v)% or more, 2.4(v / v)% or more, 2.5(v / v)% or more, 2.6(v / v)% or more, 2.7(v / v)% or more, 2.8(v / v)% or more, 2.9(v / v)% or more, 3.0(v / v)% or more, 3.1(v / v)% or more, 3.2(v / v)% or more, 3.3(v / v)% or more, 3.4(v / v)% or more, or 3.5(v / v)% or more. On the other hand, from the standpoint of reducing the ethanol taste that is unsuitable for a low-alcohol beer-taste beverage and improving drinkability, it is preferable that the alcohol content of the beer-taste beverage of one embodiment of the present invention be 3.8 (v / v)% or less, 3.7 (v / v)% or less, 3.6 (v / v)% or less, 3.5 (v / v)% or less, 3.4 (v / v)% or less, or 3.3 (v / v)% or less. It may be 0.2(v / v)% or less, 3.1(v / v)% or less, 3.0(v / v)% or less, 2.9(v / v)% or less, 2.8(v / v)% or less, 2.7(v / v)% or less, 2.6(v / v)% or less, 2.5(v / v)% or less, 2.4(v / v)% or less, 2.3(v / v)% or less, 2.2(v / v)% or less, 2.1(v / v)% or less, or 2.0(v / v)% or less. In this specification, the alcohol content is expressed as a percentage based on volume / volume ((v / v)%). The alcohol content of a beverage can be measured by any known method, for example, by a vibration density meter. The alcohol content can be adjusted by appropriately setting the addition of dilution water or carbonated water, the type of raw material (malt, corn grits, sugar liquid, etc.), the amount of raw material, the type of enzyme, the amount of enzyme added, the timing of enzyme addition, saccharification time in the brewing tank, proteolysis time in the brewing tank, the pH in the brewing tank, the pH in the brewing process (the wort production process from the addition of malt to before the addition of yeast), the amount of acid added when adjusting the pH, the timing of pH adjustment (during brewing, during fermentation, at the completion of fermentation, before beer filtration, after beer filtration, etc.), the set temperature and holding time of each temperature range when preparing wort (including during saccharification), the original extract concentration of the pre-fermentation liquid, the original extract concentration in the fermentation process, the fermentation conditions (oxygen concentration, aeration conditions, yeast variety, amount of yeast added, yeast growth rate, timing of yeast removal, fermentation temperature, fermentation time, pressure setting, carbon dioxide concentration, amount of enzyme added, type of enzyme, timing of enzyme addition, etc.), and the addition of spirits, brewing alcohol, etc.

[0012] The beer-taste beverage of one embodiment of the present invention may contain grain-derived spirits (distilled alcoholic beverages) as the alcohol component. In this specification, spirits refers to alcoholic beverages obtained by saccharifying grains such as wheat, rice, buckwheat, corn, potatoes, sugar cane, etc., using malt or, if necessary, an enzyme agent, fermenting them using yeast, and then distilling them. Grains that are the raw material for spirits are preferably plants belonging to the Poaceae family, and more preferably wheat.

[0013] When the beer-taste beverage of the present invention is a fermented beer-taste beverage, the apparent fermentation degree is preferably less than 100%. Beer-taste beverages with a high apparent fermentation degree can suppress a feeling of fullness, but tend to be less satisfying to drink. Thus, when the beer-taste beverage of one embodiment of the present invention is a fermented beer-taste beverage, by adjusting the saccharification conditions and fermentation conditions so that the apparent fermentation degree is less than 100%, it is possible to produce a beer-taste beverage that is satisfying to drink even with a low alcohol content and that further enhances the rich flavor derived from barley.

[0014] When the beer-taste beverage of one embodiment of the present invention is a fermented beer-taste beverage, the apparent degree of fermentation will be less than 100% from the above-mentioned viewpoints, but is preferably 99% or less, more preferably 98% or less, even more preferably 97% or less, even more preferably 96% or less, and particularly preferably 95% or less, and may also be 94% or less, 93% or less, 92% or less, 91% or less, 90% or less, 89% or less, 88% or less, 87% or less, 86% or less, 85% or less, 84% or less, 83% or less, 82% or less, 81% or less, 80% or less, 79% or less, 78% or less, 77% or less, 76% or less, 75% or less, 74% or less, 73% or less, 72% or less, 71% or less, or 70% or less. On the other hand, when the beer-taste beverage of one embodiment of the present invention is a fermented beer-taste beverage, from the perspective of providing a beer-taste beverage that suppresses inappropriate feelings of fullness, the apparent fermentation degree is preferably 5% or more, more preferably 6% or more, more preferably 7% or more, even more preferably 8% or more, even more preferably 9% or more, and particularly preferably 10% or more, and also preferably 11% or more, 12% or more, 13% or more, 14% or more, 15% or more, 16% or more, 17% or more, 18% or more, 19% or more, 20% or more, 21% or more, 22% or more, 23% or more, 24% or more, 25% or more, 26% or more, It may be 27% or more, 28% or more, 29% or more, 30% or more, 31% or more, 32% or more, 33% or more, 34% or more, 35% or more, 36% or more, 37% or more, 38% or more, 39% or more, 40% or more, 41% or more, 42% or more, 43% or more, 44% or more, 45% or more, 46% or more, 47% or more, 48% or more, 49% or more, 50% or more, 51% or more, 52% or more, 53% or more, 54% or more, 55% or more, 56% or more, 57% or more, 58% or more, 59% or more, 60% or more, 61% or more, 62% or more, 63% or more, 64% or more, or 65% or more.

[0015] As used herein, "apparent fermentation degree" refers to the proportion of sugar concentration that can be consumed by yeast as a nutrient source for alcoholic fermentation to the total sugar concentration in the liquid before fermentation. For example, the apparent fermentation degree AA of the beer-taste beverage of the present invention can be calculated from the following formula (1). Formula (1): AA(%)=100×(P-Es) / P In the above formula (1), "P" is the original extract (original wort extract) and can be measured by the method described in "BCOJ Beer Analysis Methods (published by the Brewing Society of Japan, edited by the Beer Brewing Association, revised November 1, 2004)." Furthermore, "Es" indicates the apparent extract of the beer-taste beverage. The apparent extract can be calculated from the following formula (2), for example, as described in "BCOJ Beer Analysis Method (published by the Brewing Society of Japan, edited by the Beer Brewing Association, revised November 1, 2004)". Formula (2): Es=-460.234+662.649×D-202.414×D 2 (In formula (2), D is the specific gravity of the degassed beer-taste beverage.) In addition, since the apparent extract "Es" may become a negative value due to D in the above formula (2), the calculated apparent fermentation degree may exceed 100%.

[0016] The apparent fermentation degree of the beer-taste beverage can be adjusted by appropriately setting the addition of dilution water or carbonated water, type of raw materials (malt, corn grits, sugar solution, etc.), amount of raw materials, type of enzyme, amount of enzyme added (including carbohydrate-degrading enzymes, isomerases, etc.), temperature during the enzyme reaction, timing of enzyme addition, saccharification time, pH during saccharification, temperature during saccharification, pH during the brewing process (the wort production process from the addition of malt to before the addition of yeast), temperature during the brewing process, time for wort filtration, set temperatures and holding times for each temperature range when preparing wort (including during saccharification), original extract concentration in the pre-fermentation liquid, original extract concentration in the fermentation process, fermentation conditions (oxygen concentration, aeration conditions, yeast variety, amount of yeast added, yeast growth rate, timing of yeast removal, fermentation temperature, fermentation time, pressure settings, carbon dioxide concentration, amount of enzyme added, type of enzyme, timing of enzyme addition, etc.), cooling timing, cooling temperature, cooling time, etc.

[0017] When the alcohol content of a beer-taste beverage is set to 3.8 (v / v)% or less, the beverage tends to be insufficiently satisfying. However, according to one embodiment of the present invention, by adjusting the content of pyroglutamic acid within a predetermined range, it is possible to impart a satisfactory satisfying taste to a beer-taste beverage, even when the alcohol content is relatively low as described above. Pyroglutamic acid is a type of organic acid contained in malt and the like, and is a compound that does not have an amino group (-NH2) in its structure, as represented by the following formula: [ka]

[0018] From the above viewpoints, the content of pyroglutamic acid in the beer-taste beverage of one embodiment of the present invention is preferably 60 mg / L or more, more preferably 65 mg / L or more, even more preferably 70 mg / L or more, even more preferably 75 mg / L or more, even more preferably 80 mg / L or more, even more preferably 85 mg / L or more, even more preferably 90 mg / L or more, even more preferably 95 mg / L or more, particularly preferably 100 mg / L or more, and may also be 110 mg / L or more, 115 mg / L or more, 120 mg / L or more, 125 mg / L or more, 130 mg / L or more, 135 mg / L or more, 140 mg / L or more, 145 mg / L or more, or 150 mg / L or more. On the other hand, from the standpoint of producing a beer-flavored beverage with a harmonious aroma and flavor, the pyroglutamic acid content may be 600 mg / L or less, 590 mg / L or less, 580 mg / L or less, 570 mg / L or less, 560 mg / L or less, 550 mg / L or less, 540 mg / L or less, 530 mg / L or less, 520 mg / L or less, 510 mg / L or less, 500 mg / L or less, 490 mg / L or less, 480 mg / L or less, 470 mg / L or less, or 460 mg / L or less.

[0019] The pyroglutamic acid may be contained in the ingredients of the beer-taste beverage, or may be added separately during the production process (for example, a purified pyroglutamic acid product). The content of pyroglutamic acid can be adjusted by appropriately setting the addition of dilution water or carbonated water, the addition of purified pyroglutamic acid, the type of pyroglutamic acid-containing raw material (malt, barley, corn grits, sugar liquid, yeast extract, soybeans, peas, purified pyroglutamic acid, etc.), the amount of raw materials, the enzyme reaction time in the preparation process (the wort production process from the introduction of raw materials such as malt to the addition of yeast), the pH in the preparation process, the amount of acid used for pH adjustment, the timing of pH adjustment (at the time of preparation, at the time of fermentation, at the time of completion of fermentation, before beer filtration, after beer filtration, etc.), the set temperature and holding time of each temperature range when preparing wort (including during saccharification), the original extract concentration of the pre-fermentation liquid, the original extract concentration in the fermentation process, the fermentation conditions (oxygen concentration, aeration conditions, yeast variety, amount of yeast added, yeast growth number, timing of yeast removal, fermentation temperature, fermentation time, pressure setting, carbon dioxide concentration, etc.), and the addition of spirits or brewing alcohol. In this specification, the content of pyroglutamic acid can be measured, for example, by high performance liquid chromatography.

[0020] In one embodiment of the beer-taste beverage of the present invention, from the standpoint of ensuring a satisfactory drinkability, the product of the alcohol content (A) (unit: v / v %) and the pyroglutamic acid content (C) (unit: mg / L) [(A) x (C)] is preferably 100 or more, more preferably 150 or more, even more preferably 200 or more, even more preferably 250 or more, even more preferably 300 or more, even more preferably 350 or more, even more preferably 400 or more, even more preferably 450 or more, even more preferably 500 or more, particularly preferably 550 or more, and may also be 600 or more, 650 or more, 700 or more, 750 or more, 800 or more, 850 or more, 900 or more, 950 or more, or 1,000 or more. On the other hand, from the standpoint of producing a beer-taste beverage with a light drinking experience, the product of the alcohol content (A) (unit: v / v %) and the pyroglutamic acid content (C) (unit: mg / L) [(A) x (C)] is preferably 2,000 or less, more preferably 1,900 or less, even more preferably 1,800 or less, still more preferably 1,700 or less, and particularly preferably 1,600 or less, and may also be 1,590 or less, 1,570 or less, 1,550 or less, 1,500 or less, 1,450 or less, 1,400 or less, 1,350 or less, 1,300 or less, 1,250 or less, 1,200 or less, 1,150 or less, 1,100 or less, 1,050 or less, or 1,000 or less.

[0021] The beer-taste beverage of one embodiment of the present invention preferably further contains isoamyl alcohol. Isoamyl alcohol is a type of aroma component that exhibits a brewed aroma. According to one embodiment of the present invention, by further containing isoamyl alcohol in addition to setting the pyroglutamic acid content within the above-mentioned range, it is possible to impart a suitable aftertaste to the beer-taste beverage. In view of the above, the isoamyl alcohol content of the beer-taste beverage of one embodiment of the present invention is preferably more than 20 mg / L, more preferably 21 mg / L or more, even more preferably 22 mg / L or more, even more preferably 23 mg / L or more, even more preferably 24 mg / L or more, even more preferably 25 mg / L or more, even more preferably 26 mg / L or more, even more preferably 27 mg / L or more, particularly preferably 28 mg / L or more, and may also be 29 mg / L or more, 30 mg / L or more, 31 mg / L or more, 32 mg / L or more, 33 mg / L or more, 34 mg / L or more, 35 mg / L or more, 36 mg / L or more, 37 mg / L or more, 38 mg / L or more, 39 mg / L or more, or 40 mg / L or more. On the other hand, from the standpoint of reducing a solvent odor unsuitable for beer-taste beverages, the isoamyl alcohol content in the beer-taste beverage of one embodiment of the present invention is preferably 190 mg / L or less, more preferably 185 mg / L or less, more preferably 180 mg / L or less, more preferably 175 mg / L or less, even more preferably 170 mg / L or less, even more preferably 165 mg / L or less, even more preferably 160 mg / L or less, even more preferably 155 mg / L or less, even more preferably 150 mg / L or less, and ....

There are various types of barley, such as two-rowed barley and six-rowed barley, and any of these may be used. Furthermore, in addition to normal malt, colored malt may also be used. When using colored malt, different types of colored malt may be appropriately combined, or one type of colored malt may be used.

[0041] The malt used in the beer-taste beverage of the present invention preferably has a modification of 80% or more. If the modification is less than 80%, the viscosity and turbidity of the wort will increase, and production efficiency such as wort filterability and beer filterability will deteriorate. Therefore, it is preferable to use malt with a modification of 80% or more. In the examples and comparative examples described below, malt with a modification of 80% or more was used. The modification can be measured by the method described in 3.1.3.8 Modification and Homogeneity (Calcofluor Carlsberg Method-EBC) in MEBAK Raw Materials Barley Adjuncts Malt Hops And Hop Products Published by the Chairman Dr. Fritz Jacob Self-published by MEBAK 85350 Freising-Weihenstephan, Germany 2011. Furthermore, in the beer-taste beverage of one embodiment of the present invention, the malt used is preferably selected appropriately depending on the desired color of the beer-taste beverage, and the malt selected may be a single type, or two or more types may be selected in combination.

[0042] Malt contains pyroglutamic acid. Therefore, in the present invention, in order to make the pyroglutamic acid content of the beer-taste beverage of the present invention fall within the range specified in the present specification, it is preferable to set the ratio of malt in the raw materials to a certain range. Specifically, the malt ratio (the ratio of all malt used) is preferably 50% by mass or more, and also 51% by mass or more, 52% by mass or more, 53% by mass or more, 54% by mass or more, 55% by mass or more, 56% by mass or more, 57% by mass or more, 58% by mass or more, 59% by mass or more, 60% by mass or more, 61% by mass or more, 62% by mass or more, 63% by mass or more, 64% by mass or more, 65% by mass or more, 66% by mass or more, more than 66% by mass, 66.6% by mass or more, 67% by mass or more, 68% by mass or more, 69% by mass or more, 70% by mass or more, 71% by mass or more, 72% by mass or more , 73% by mass or more, 74% by mass or more, 75% by mass or more, 76% by mass or more, 77% by mass or more, 78% by mass or more, 79% by mass or more, 80% by mass or more, 81% by mass or more, 82% by mass or more, 83% by mass or more, 84% by mass or more, 85% by mass or more, 86% by mass or more, 87% by mass or more, 88% by mass or more, 89% by mass or more, 90% by mass or more, 91% by mass or more, 92% by mass or more, 93% by mass or more, 94% by mass or more, 95% by mass or more, 96% by mass or more, 97% by mass or more, 98% by mass or more, 99% by mass or more, or 100% by mass. By increasing the malt ratio, a beer-taste beverage can be produced that allows the rich flavor derived from malt and the umami of barley to be more strongly felt. Furthermore, from the perspective of providing a beverage that is less likely to cause an inappropriate feeling of fullness, the malt ratio in the beer-taste beverage of one embodiment of the present invention is less than 100% by mass, 99% or less, 98% or less, 97% or less, 96% or less, 95% or less, 94% or less, 93% or less, 92% or less, 91% or less, 90% or less, 89% or less, 88% or less, 87% or less, 86% or less, 85% or less, 84% or less, 83% or less, 82% or less, 87% or less, 8 ... 1% by mass or less, 80% by mass or less, 79% by mass or less, 78% by mass or less, 77% by mass or less, 76% by mass or less, 75% by mass or less, 74% by mass or less, 73% by mass or less, 72% by mass or less, 71% by mass or less, 70% by mass or less, 69% by mass or less , 68% by mass or less, 67% by mass or less, less than 67% by mass, 66.6% by mass or less, 66% by mass or less, 65% by mass or less, 64% by mass or less, 63% by mass or less, 62% by mass or less, 61% by mass or less, or 60% by mass or less. In this specification, the malt ratio means a value calculated in accordance with the Liquor Tax Act and the Interpretation Notice of Liquor-related Administrative Laws and Regulations, etc., which came into effect on April 1, 2018.

[0043] When the malt ratio is suppressed, it is preferable to increase the amount of raw materials (carbon source, nitrogen source) other than malt that can be assimilated by yeast. Examples of carbon sources of raw materials that can be assimilated by yeast include monosaccharides, disaccharides, trisaccharides, their sugar solutions, and liquid sugars containing carbon sources, and examples of nitrogen sources include yeast extract, soy protein, malt, soybeans, yeast extract, peas, wheat malt, ungerminated grains, and decomposition products thereof. Examples of ungerminated grains include ungerminated barley, wheat, rye, oats, oats, pearl barley, oats, rice (white rice, brown rice, etc.), corn, sorghum, potatoes, beans (soybeans, peas, etc.), buckwheat, sorghum, millet, and barnyard millet. Starches obtained from these grains and extracts thereof may also be used. In one embodiment of the present invention, the malt ratio may be adjusted by using the raw materials listed above as auxiliary raw materials.

[0053] Examples of sweeteners include commercially available saccharified solutions obtained by decomposing grain-derived starch with acids or enzymes, sugars such as sucrose and commercially available starch syrup, sugars of three or more sugars, sugar alcohols, isomerized sugar, natural sweeteners such as stevia, and artificial sweeteners. These sugars may be in the form of a liquid such as a solution, or a solid such as a powder. There are also no particular limitations on the type of raw grain for starch, the method of purifying starch, and the conditions for hydrolysis with enzymes or acids. For example, sugars with a higher ratio of maltose may be used by appropriately setting the conditions for hydrolysis with enzymes or acids. In addition, sucrose, fructose, glucose, mannose, arabinose, galactose, xylose, rhamnose, ribose, fucose, lactose, maltose, trehalose, maltotriose, maltotetraose, maltopentaose, isomaltose, isomaltotriose, isomaltotetraose, isomaltopentaose, lactosucrose, 4'-galactosyl lactose, 1-kestose, nystose, fructofuranosyl nystose, raffinose, stachyose, xylobiose, xylotriose, panose, and solutions thereof (sugar solutions) may also be used.

[0059] Examples of preservatives include benzoic acid, benzoates such as sodium benzoate, benzoic acid esters such as propyl paraoxybenzoate and butyl paraoxybenzoate, and dimethyl dicarbonate. In addition, commercially available preparations such as Strong Sunplazer (manufactured by San-Ei Gen F.F.I. Co., Ltd., a mixture of sodium benzoate and butyl benzoate) may be used as preservatives. These preservatives may be used alone or in combination of two or more. The amount of the preservative to be blended is preferably 5 to 1200 ppm by mass, more preferably 10 to 1100 ppm by mass, even more preferably 15 to 1000 ppm by mass, and even more preferably 20 to 900 ppm by mass.

[0060] Examples of salts include sodium chloride, potassium acid phosphate, acid calcium phosphate, ammonium phosphate, magnesium sulfate, calcium sulfate, potassium metabisulfite, calcium chloride, magnesium chloride, potassium nitrate, ammonium sulfate, potassium chloride, monosodium citrate, disodium citrate, and trisodium citrate. These salts may be used alone or in combination of two or more kinds.

[0061] 1.2 Carbon dioxide The carbon dioxide gas contained in the beer-taste beverage of one embodiment of the present invention may be carbon dioxide gas contained in the raw materials, or may be dissolved by mixing with carbonated water or by adding carbon dioxide gas. The beer-taste beverage of one embodiment of the present invention undergoes alcoholic fermentation, and therefore the carbon dioxide gas produced in this fermentation process can be used as is, although the amount of carbon dioxide gas may be adjusted by adding carbonated water as appropriate.

[0062] The carbon dioxide concentration of the beer-taste beverage of one embodiment of the present invention is preferably 0.30 (w / w)% or more, more preferably 0.35 (w / w)% or more, even more preferably 0.40 (w / w)% or more, still more preferably 0.42 (w / w)% or more, particularly preferably 0.45 (w / w)% or more, and is preferably 0.80 (w / w)% or less, more preferably 0.70 (w / w)% or less, even more preferably 0.60 (w / w)% or less, still more preferably 0.57 (w / w) or less, particularly preferably 0.55 (w / w)% or less, and may also be 0.54 (w / w)% or less, 0.53 (w / w)% or less, 0.52 (w / w)% or less, 0.51 (w / w)% or less, or 0.50 (w / w)% or less. In this specification, the carbon dioxide concentration can be measured using a gas volume measuring device (e.g., GVA-500 (manufactured by Kyoto Electronics Manufacturing Co., Ltd.) after adjusting the temperature of the beverage to 20°C by immersing the container containing the beverage in question in a water bath at 20°C for 30 minutes or more while shaking it occasionally.

[0063] When the beer-taste beverage of one embodiment of the present invention is a packaged beverage, the carbon dioxide pressure of the packaged beverage may be appropriately adjusted within the range that results in the above-mentioned carbon dioxide concentration. 2 Below, 4.5kg / cm 2 or less than 4.0kg / cm 2 and 0.20 kg / cm 2 More than 0.50kg / cm 2 or more than 1.0kg / cm 2 Any of these upper and lower limits may be combined.

The pressure can be measured by a method well known to those skilled in the art, for example, by fixing a sample at 20°C to an internal gas pressure gauge, opening the stopcock of the internal gas pressure gauge to release the gas, closing the stopcock again, swinging the internal gas pressure gauge and reading the value when the needle reaches a certain position, or by using a commercially available gas pressure measuring device.

[0064] 1.3 Other additives Various additives may be added to the beer-taste beverage of one embodiment of the present invention as necessary, provided the effects of the present invention are not impaired. Such additives include, for example, colorants, foam-forming agents, fermentation promoters, yeast extracts, protein substances such as peptide-containing substances, and flavorings such as amino acids. The coloring agent is used to give the beverage a beer-like color, and caramel coloring can be used. The foam-forming agent is used to form a beer-like foam in the beverage or to maintain the foam in the beverage, and can be appropriately selected from plant-extracted saponin substances such as soybean saponin and quillaja saponin, plant proteins such as corn and soybeans, peptide-containing substances such as collagen peptides, yeast extracts, raw materials originating from milk, and the like. The fermentation promoter is used to promote fermentation by yeast, and examples thereof include yeast extract, bran components such as rice or wheat, vitamins, and mineral agents, which may be used alone or in combination.

[0065] 1.4 Packaged beverages The beer-taste beverage of one embodiment of the present invention may be a packaged beverage that is packaged in a container. Containers of any shape and material may be used for packaged beverages, and examples of containers include bottles, cans, barrels, and plastic bottles, with cans, bottles, and plastic bottles being particularly preferred from the standpoint of ease of portability.

[0066] 2. Manufacturing method of beer-flavored beverage The present invention also relates to a method for producing a beer-taste beverage. Specifically, one embodiment of the method for producing the beer-taste beverage comprises adjusting the alcohol content to 1.0 (v / v)% or more and 3.8 (v / v)% or less, and the pyroglutamic acid content to 60 mg / L or more. The method for producing the beer-taste beverage of one embodiment of the present invention is not particularly limited, and may be a method involving a fermentation step or a method involving no fermentation step. Below, we will explain a method for producing a fermented beer-taste beverage through a fermentation process, and a method for producing a non-fermented beer-taste beverage without going through a fermentation process.

[0067] 2.1 Method for producing fermented beer-flavored beverage One embodiment of the method for producing a fermented beer-taste beverage of the present invention includes a fermentation process using yeast, and may include, for example, the following steps (1) to (3). Step (1): A step of obtaining a pre-fermentation liquid by subjecting a raw material to at least one of a saccharification treatment, a boiling treatment, and a solid content removal treatment. Step (2): A step of cooling the pre-fermentation liquid obtained in step (1) to obtain a cooled pre-fermentation liquid. Step (3): A step of adding yeast to the cooled pre-fermentation liquid obtained in step (2) to carry out alcoholic fermentation.

[0068] Furthermore, the production method according to one aspect of the present invention may include a step of checking and / or adjusting the alcohol content and the pyroglutamic acid content in addition to the above steps (1) to (3). This step will be described later as step (4). Note that the production method according to one aspect of the present invention does not include a dealcoholization step.

[0069] <Process (1)> Step (1) is a step in which various raw materials are subjected to at least one of saccharification, boiling, and solid content removal treatments to obtain a pre-fermentation liquid. For example, when malt is used as one of the various raw materials, water and the various raw materials including malt are charged into a brewing kettle or brewing tank, and, if necessary, an enzyme agent such as a polysaccharide-degrading enzyme or a protease that promotes the conversion of components derived from the raw materials may be added before fermentation. Examples of the enzyme agent include amylase, protease, purine nucleosidase, deaminase, polyphenol oxidase, glucanase, xylase, pectinase, cellulase, lipase, glucosidase, xanthine oxidase, transglucosidase, glucoamylase, and uricase. These enzyme agents may be heat-resistant or non-heat-resistant. The type of enzyme agent can be selected according to the timing of addition and the process to which it is added. The above enzyme agents may be used alone or in combination of two or more types. In addition, examples of the enzyme agents include those that fall under "(3) the following enzyme agents added during the brewing process for the purpose of streamlining sake brewing, etc." in Article 3 "7. Items not to be treated as raw materials for sake" of the Liquor Tax Act and the Notification of Liquor Administration Law (revised on June 27, 2018). By adding these enzyme agents, the component composition of the resulting beer-taste beverage can be efficiently adjusted. As various raw materials other than malt, hops, preservatives, sweeteners, water-soluble dietary fiber, bittering agents or bitterness imparting agents, antioxidants, flavorings, acidulants, salts, etc. may be added. These may be added before saccharification treatment, during saccharification treatment, or after completion of saccharification treatment. Furthermore, these may be added during or after alcoholic fermentation in the next step.

[0070] The mixture of various raw materials is heated to saccharify the starch in the raw materials. In the present specification, the degree of saccharification in the saccharification is not particularly limited, and for example, all or a portion of the starch may be saccharified. The temperature and time of the saccharification treatment are preferably adjusted as appropriate taking into consideration the type of malt used, the malt ratio, the water and raw materials other than malt, the type and amount of enzymes used, the original extract concentration of the final beverage, etc. In one aspect of the present invention, from the viewpoint of adjusting the apparent fermentation degree of the beer-taste beverage to the above range, the saccharification treatment temperature is preferably 55 to 80°C and the saccharification treatment time is preferably 1 to 240 minutes. In order to further reduce the apparent fermentation degree, it is preferable to carry out the saccharification treatment at 72 to 85°C. After the saccharification treatment, filtration is performed to obtain a saccharified liquid.

[0071] It is preferable to subject this saccharified solution to a boiling treatment. When hops, bittering agents, etc. are used as raw materials during the boiling treatment, it is preferable to add these agents. Hops, bittering agents, etc. may be added during the period from the start of boiling the saccharified solution to before the end of boiling. Instead of the above-mentioned saccharified liquid, a pre-fermentation liquid may be prepared by adding hops, bittering agents, etc. to a malt extract and warm water, followed by boiling.

[0072] In addition, when malt is not used as one of the various raw materials, liquid sugar containing a carbon source, a nitrogen source as an amino acid-containing raw material other than barley or malt, hops, preservatives, sweeteners, water-soluble dietary fiber, bittering agents or bitterness imparting agents, antioxidants, flavorings, acidulants, salts, etc. may be mixed with warm water to prepare a liquid sugar solution, which may then be boiled to prepare a pre-fermentation liquid. When hops are used, they may be added before the boiling treatment or between the start and end of boiling of the liquid sugar solution.

[0073] <Process (2)> Step (2) is a step of cooling the pre-fermentation liquid obtained in step (1) to obtain a cooled pre-fermentation liquid. After completion of the boiling treatment, the mixture is transferred to a whirlpool and cooled to 0 to 23° C. After cooling, solid matters such as coagulated proteins may be removed, and the original extract concentration may be adjusted. Through such treatment, a cooled pre-fermentation liquid is obtained.

[0074] <Process (3)> Step (3) is a step of adding yeast to the cooled pre-fermentation liquid obtained in step (2) to carry out alcoholic fermentation. The yeast used in this step can be appropriately selected taking into consideration the type of fermented beverage to be produced, the desired flavor, fermentation conditions, etc., and either top-fermenting yeast or bottom-fermenting yeast may be used.

[0075] The yeast may be added to the raw material as a yeast suspension, or the yeast may be concentrated by centrifugation or sedimentation to form a slurry, which is then added to the pre-fermentation liquid. Alternatively, the yeast may be added after centrifuging and removing the supernatant completely. The amount of yeast added to the raw material can be appropriately determined, but for example, 5×10 6 cells / mL ~ 1×10 8 The concentration is approximately 1.5 mg / mL.

[0076] Various conditions such as fermentation temperature and fermentation period during alcoholic fermentation can be set as appropriate, but from the viewpoint of adjusting the apparent fermentation degree, it is preferable to ferment under conditions of, for example, 8 to 25° C. and 5 to 10 days. The temperature (increase or decrease) or pressure of the fermentation liquid may be changed during the fermentation process. The apparent fermentation degree of the beer-taste beverage can be adjusted by appropriately setting the type, amount and timing of addition of polysaccharide-degrading enzymes such as transglucosidase and amylase, and can also be adjusted by changing the temperature (increasing or decreasing the temperature) or pressure of the fermentation liquid during the fermentation process. After completion of this step, the yeast may be removed using a filter or the like, and additives such as water, flavorings, acidulants, and colorants may be added as necessary. In this way, the apparent fermentation degree of the resulting beer-taste beverage can be adjusted to be within the desired range by appropriately adjusting the conditions for the saccharification treatment in step (1) and the alcoholic fermentation in step (3) described above.

[0077] <Process (4)> Step (4) is a step of checking and / or adjusting the alcohol content and the pyroglutamic acid content. The alcohol content and pyroglutamic acid content can also be adjusted in steps (1) and (2) by appropriately setting the type and amount of raw materials, preparation conditions (timing of adding raw materials, etc.), yeast species, fermentation conditions, etc. Therefore, in step (4), it is preferable to measure these and confirm whether they are within the above-mentioned range. If they are outside the range, it is preferable to adjust them by adding alcohol raw materials or purified pyroglutamic acid or diluting them. In this step, the alcohol content and pyroglutamic acid content are preferably adjusted by diluting them with water or carbonated water.

[0078] The adjustment of the alcohol content and the pyroglutamic acid content may be carried out in parallel with step (1), step (2) and / or step (3), between step (1) and step (2), between step (2) and step (3), or after step (3). The alcohol content and the pyroglutamic acid content may be checked at any of the above timings.

[0079] These steps may be followed by steps such as a storage step and a filtration step that are well known to those skilled in the art in the production of beer-taste beverages. The beer-taste beverage thus obtained is filled into specified containers and distributed to the market as a finished product. There are no particular limitations on the method for packaging the beer-taste beverage, and any method known to those skilled in the art can be used. In the packaging process, the beer-taste beverage is filled and sealed in a container. For the packaging process, containers of any shape and material can be used, and examples of containers are as described above.

[0080] 2.2 Manufacturing method for non-fermented beer-taste beverage When the beer-taste beverage of one embodiment of the present invention is a non-fermented beer-taste beverage, it can be produced by a general method for producing a non-fermented beer-taste beverage. Specific examples of the method for producing a non-fermented beer-taste beverage of one embodiment of the present invention include a method having the following steps (a) to (c). Step (a): A step of obtaining a primary raw material liquid by using various raw materials and carrying out at least one of a blending process (mixing of various raw materials), an alcohol raw material addition process, a saccharification process, a boiling process, and a solid content removal process. Step (b): A step of sterilizing the primary raw material liquid as necessary, diluting it, and adding carbon dioxide gas by a carbonation process. Step (c): A step of checking and / or adjusting the alcohol content and pyroglutamic acid content. If necessary, precipitates can be separated and removed at each stage by filtration, centrifugation, etc. By using normal soft drink production processes for these steps, it is possible to easily produce a non-fermented beer-taste beverage even without fermentation equipment.

[0081] A specific method for obtaining the primary raw material liquid in step (a) may be the same as that in step (1) described above. When preparing a non-fermented alcohol-containing beer-taste beverage, an alcoholic beverage can be added as an alcoholic raw material to prepare an alcoholic primary raw material liquid. The alcoholic beverage to be added is not particularly limited, but examples thereof include raw material alcohol, shochu, awamori, whiskey, brandy, vodka, rum, tequila, gin, and other spirits.

[0082] Carbon dioxide gas is added to the primary raw material liquid or the alcohol-containing primary raw material liquid by the carbonation treatment in step (b). The carbon dioxide gas may be added directly to the primary raw material liquid or the alcohol-containing primary raw material liquid, or may be added by mixing the primary raw material liquid or the alcohol-containing primary raw material liquid with carbonated water after preparing the primary raw material liquid in a concentrated state. When adding the carbon dioxide gas, additives such as preservatives, sweeteners, flavors, acidulants, and colorants may be added as necessary. In addition, in order to remove substances that cause sediment or unpleasant flavors, it is preferable to carry out a process to remove precipitates before the carbonation step. The sterilization and dilution steps may be carried out before the carbonation treatment, after filling the container, or both.

[0083] Similarly to the above step (4), it is preferable to carry out step (c) of checking and / or adjusting the alcohol content and the pyroglutamic acid content. Step (c) may be carried out between steps (a) and (b), after steps (a) and (b), or in parallel with steps (a) and / or (b).

[0084] The non-fermented, beer-taste beverage of one embodiment of the present invention thus obtained is filled into specified containers and distributed on the market as a finished product. The method for packaging the carbonated beverage is not particularly limited, and any method known to those skilled in the art can be used. In the packaging step, the carbonated beverage of the present invention is filled and sealed in a container. In the packaging step, containers of any shape and material can be used, and examples of containers are as described above.

[0085] 3. Method for improving the flavor of beer-flavored beverages The present invention also relates to a method for improving the flavor of a beer-taste beverage. Specifically, the flavor improving method of one embodiment of the present invention comprises adjusting the alcohol content to 1.0 (v / v)% or more and 3.8 (v / v)% or less, and adjusting the pyroglutamic acid content to 60 mg / L or more.

[0086] In this specification, the "flavor" of a beer-taste beverage includes the umami of barley, the rich flavor derived from barley, drinkability, and depth of flavor. In addition, in this specification, "improving flavor" or "improving flavor" means that a beverage whose alcohol content and pyroglutamic acid content are adjusted to satisfy the above ranges achieves at least one of an increased rich flavor derived from barley, improved drinkability, and reduced wateriness, compared to a beverage whose alcohol content and pyroglutamic acid content do not satisfy the above ranges.

In each example, the amount and type of raw materials such as malt and hops, mashing pattern, amount and timing of transglucosidase addition, set temperature in each temperature range when preparing wort, retention time, pH adjustment, turbidity during wort filtration, timing of hop addition, boiling time, yeast variety, fermentation conditions, etc. were appropriately set to adjust the alcohol content, pyroglutamic acid content, isoamyl alcohol content, and acidulant content shown in Table 9. In addition to setting the above conditions, pyroglutamic acid and isoamyl alcohol were added as necessary to adjust the values ​​shown in the table. In all examples, the apparent fermentation degree was 95% or less, and the carbohydrate content was more than 1.1 g / 100 mL and 4.5 g / 100 mL or less.

[0103] <Sensory evaluation> The resulting beer-taste beverages were evaluated by the same six panelists who sampled each beverage, using the same methods and evaluation criteria as in Examples 1-69. [Table 9]

[0104] Examples 74 to 87 <Beverage preparation> The crushed barley malt, rice, corn and starch were put into a brewing tank containing 120 L of hot water, and the temperature was gradually raised and maintained, and the water was filtered to remove malt grains, etc. After filtration, the raw material liquid and hops were put into a boiling kettle and the volume was adjusted to 100 L with hot water to obtain hot wort. The resulting hot wort was cooled and aerated with oxygen to obtain 60 L of pre-fermentation liquid before the addition of yeast.

[0105] Beer yeast (bottom fermenting yeast) was added to the pre-fermentation liquid obtained in this manner and fermented for approximately one week. After a further maturation period of approximately two weeks, the yeast was removed by filtration and extract adjustment water was added to prepare a beer-flavored beverage. In each example, the amounts and types of raw materials such as malt, hops, rice, corn, and starch, the mashing pattern, the set temperatures for each temperature range when preparing the wort, the retention time, pH adjustment, the turbidity during wort filtration, the timing of hop addition, the boiling time, the yeast variety, the fermentation conditions, and the like were appropriately set to obtain the malt ratio, alcohol content, pyroglutamic acid content, isoamyl alcohol content, and acidulant content shown in Table 10. In addition to setting the above conditions, pyroglutamic acid and isoamyl alcohol were added as necessary to adjust the values ​​shown in the table. In all examples, the apparent fermentation degree was 95% or less, and the carbohydrate content was more than 1.1 g / 100 mL and 4.5 g / 100 mL or less.
