Description

The present invention relates to a beer-taste beverage in which the aroma characteristic of citrus hops is emphasized, and a method for producing the same.

It is known that the aroma given to a beverage has a great influence on the character formation of a beverage product. Floral, spicy, citrus, fruity, hoppy, spicy, muscat and the like are commonly used as words to express aroma characteristics.

The strength of hop aroma can be controlled by the usage of hops. Normally, hops are added to wort during boiling, but in order to emphasize the hop aroma, it can be realized by adding hops immediately before the end of boiling or while standing in a war loop pool tank and not applying heat as much as possible. The use of hops in the above preparation process is also called "kettle hopping".

If the hop aroma is further emphasized, there is also a method of adding hops to low-temperature young beer during fermentation called "dry hopping". While this dry-hopping beer can extremely emphasize the flavor of hops, the flavor is more pungent and gives a rough sensory evaluation impression compared to kettle-hopping beer.

So far, a method for producing a fermented malt beverage, which has the advantages of "dry hopping" to emphasize the hop aroma and "kettle hopping" with less roughness, has been known (see, for example, Patent Documents 1 to 3). There is still a need for improvements in the hop aroma of individual hop varieties.

The present invention will be specifically described with reference to the following examples, but the present invention is not limited to these examples.

Evaluation of test products blended with hop varieties with different aroma characteristics (1)
In Test Example 1 below, a healthy brucker hop (country of origin: Germany) (Hopptainer) with a spicy and herbal aroma and a citra hop (country of origin: USA) with a grapefruit-like fruity aroma (grapefruit-like aroma) ) (Barth) was used to prepare a test product. The blending amount of hops is as shown in Table 1.
Specifically, a mixture of light-colored malt (light-colored malt: Souffle, France) and water was saccharified by an infusion saccharification method to prepare a wort prepared with a sugar content adjusted to 15 degrees and boiled. The boiled wort was allowed to stand at 90 ° C. for 60 minutes. The wort after standing was filtered through a filter paper, and the wort after filtration was cooled to about 12 ° C. with ice water, and then hops (Healthbrooker hops and Citra hops) were added. Brewer's yeast was added to the cooled wort, and main fermentation was carried out for 1 week and post-fermentation was carried out for 14 days. Then, it was diluted with carbonated water so that the sugar content became 12 degrees, and a test product (test numbers 1 to 7) was prepared.

In Test Example 2 below, test products (test numbers 8 to 12) were prepared in the same manner as in Test Example 1 except that Citra hops were used alone. The blending amount of citra hops is shown in Table 2.

The sensory evaluation of the test products (test numbers 1 to 12) of Test Examples 1 and 2 below was performed in 4 stages as shown in Table 3, and was performed by a trained panel of 5 people.

Test Example 1
Test numbers 4 to 7 are a blend of 2.85 g / L to 2.95 g / L of health bruker hops (health bruker) and 0.15 g / L to 0.05 g / L of citra hops (citra). Among the spicy herbal scents of health bruker hops, the grapefruit-like fruity scent characteristic of citra hops was emphasized and had a more favorable scent.

Test number 3 is a blend of 2.97 g / L of health brooker hops and 0.03 g / L of citra hops, and is different from the case of health brooker hops alone, with the addition of a grapefruit-like fruity aroma. , Had a favorable aroma.

Test No. 2 is a blend of 2.98 g / L of health brooker hops and 0.02 g / L of citra hops, but unlike the single use of health brooker hops, the scent of citrus hops is faint. It had a slightly favorable scent.

Test No. 1 is a blend of 2.99 g / L of health brooker hops and 0.01 g / L of citra hops, but with a monotonous herbal scent like when the health brooker hops are used alone. The scent of citra hops was not felt and it had an unfavorable aroma.

Test Example 2
In Test Example 2, test numbers 8 to 12 are samples in which the citrus hops are adjusted from 0.01 g / L to 0.15 g / L, but the grapefruit-like fruity aroma of the citrus hops is faint. Only felt, and no favorable aroma was obtained. In particular, in Test Nos. 11 and 12 of Test Example 2, the scent of citrus hops was hardly felt, whereas in Test Nos. 4 and 5 of Test Example 1 in which the amount of citrus hops was smaller, the characteristic scent was felt. It was an interesting result that I could feel it.

From the results of Test Examples 1 and 2, it is more preferable to add citra hops having different aroma characteristics to the health brucker hops having a monotonous herbal scent, because the scent of the citra hops is emphasized even if the amount is small. It turns out that it can produce scents.

Component analysis of test brewed products The test products (test numbers 1 to 7) in Table 1 above were analyzed, and index components for obtaining a preferable aroma were searched for. As a result, it was found that the Citra hop contains a large amount of a novel component (hop component A) that is not found in the Healthbrooker hop. The hop component A was characterized by having an appearance time difference after 10 minutes with respect to the retention time of the internal standard substance borneol when measured by gas chromatography-mass spectrometry (GC / MS). Further, the response (height) of 91 m / z, 92 m / z, and 93 m / z, which is detected as an m / z value of 50 or more in the retention time, is 91 m / z> 92 m / z> 93 m / z. .. FIG. 1 shows the spectral data for the hop component A. The analysis conditions of gas chromatograph mass spectrometry (GC / MS) are as follows.
Column: Capillary column (trade name: HP-INNOWAX) (length 60 m, inner diameter 0.25 mm, film thickness 0.25 μm)
Oven temperature: 40 ° C, 0.3 minutes-3 ° C / min → 240 ° C, 20 minutes Carrier gas: He, 10psi constant pressure air transfer line temperature: 240 ° C
MS ion source temperature: 230 ° C
MSQ pole temperature: 150 ° C
Front inlet temperature: 200 ° C
Monitoring ions: In addition to the following quantitative ions, 91 m / z and 92 m / z of hop component A are added as component identification ions.
Quantitative ions:
・ Borneol: m / z = 110
-Β-Udesmall: m / z = 149
・ Linalool: m / z = 93
-Hop component A: m / z = 93.
The concentrations of β-eudesmol and linalool were calculated in units of ppb. For the concentration of the hop component A in the beverage, the response ratio (%) of the quantitative ion (93 m / z) to the ion 110 m / z of the added internal standard substance borneol was determined, and the hop component A in the beverage was based on this ratio. The concentration was quantified.

Linalool was used as an index for the overall intensity of hop aroma, and β-Eudesmol was selected as an index peculiar to health brucker hops for analysis. The results are shown in Table 4 below.

The component value of hop component A increased from 0.43 to 0.71 as the formulation of citra hops increased in test numbers 1-7. The ratio of linalool to hop component A decreased from 403.34 to 252.62, and the ratio of β-eudesmol decreased from 107.03 to 62.40.

Test numbers 13 to 16 were prepared in the same manner as the test products of test numbers 1 to 7 by changing only the blending amount of the hops used, and sensory evaluation and component analysis were performed in the same manner. The sensory evaluation of the test products of test numbers 13 to 16 was performed in 4 stages as shown in Table 3, and was performed by a trained panel of 5 people.

Test No. 13 had a favorable aroma with the addition of a grapefruit-like fruity aroma, unlike the case of the Healthbrooker hop alone. The component value of the hop component A was 0.24, the ratio of linalool to the hop component A was 371.07, and the ratio of β-eudesmol was 97.47.

Test No. 14 had a more preferable aroma in which the grapefruit-like fruity aroma characteristic of citra hops was emphasized among the spicy herbal aromas of healthbrucker hops. The component value of the hop component A was 0.26, the ratio of linalool to the hop component A was 343.75, and the ratio of β-eudesmol was 89.38.

In Test 15, a grapefruit-like fruity scent was added, which was different from that of the Healthbrooker hop alone, and the hop had a favorable scent. The component value of the hop component A was 0.95, the ratio of linalool to the hop component A was 366.68, and the ratio of β-eudesmol was 96.17.

In Test 16, the grapefruit-like fruity aroma of citra hops was emphasized and had a more favorable aroma. The component value of hop component A increased to 1.10, while the ratio of linalool to hop component A decreased to 320.32 and the ratio of β-eudesmol decreased to 82.44.

From the above results, when the consistency with the result of the sensory evaluation was confirmed, the functionally preferable range was that the ratio of β-eudesmol to the hop aroma component A was 105 or less (preferably 100 or less) and in the beverage. It was found that the concentration of the hop component A in the above was 0.24% or more.

Evaluation of test products blended with hop varieties with different aroma characteristics (2)
In order to grasp the sensory evaluation and component values of other varieties, a test product was prepared in the same manner as above using the Haratau Tradition hop (country of origin: Germany) (Hopptainer), and the sensory evaluation and analysis were performed. went. The amount of hops and the results are shown in Table 5 below.
Specifically, a mixture of light-colored malt (light-colored malt: Souffle, France) and water was saccharified by an infusion saccharification method to prepare a prepared wort having a sugar content adjusted to 15 degrees. The wort was heated with an electric heater and boiled. At this time, the boiling intensity was controlled to be constant so that the evaporation rate became 10% in 60 minutes. The boiled wort was allowed to stand at 90 ° C. for 60 minutes. The wort after standing was filtered through a filter paper, and the wort after filtration was cooled to about 12 ° C. with ice water, and then Haratau Tradition hops and Citra hops were added. Brewer's yeast was added to the cooled wort, and main fermentation was carried out for 1 week and post-fermentation was carried out for 14 days. Then, the test product (test numbers 17 to 23) was produced by diluting with carbonated water so that the sugar content became 12 degrees.

Haratau Tradition hops are a variety with a strong floral scent. Unlike the Health Brooker hops, the test products using the Haratau Tradition hops had a strong floral-like scent even when the blending ratio of the Citra hops was increased, resulting in a monotonous scent, and a favorable scent could not be obtained. From this, it is best to use a small amount of citra hops in combination with health bruker hops to emphasize their characteristic aroma, and the cause is β-eudesmol contained in health bruker hops. Has become clear that has an important role.

From the above, in order to emphasize the characteristics of the aroma while reducing the amount of rare hops used, the ratio of β-eudesmol to hop component A (β-eudesmol / hop component A) is 105 or less (preferably). Is in the range of 100 or less, more preferably 95 or less, still more preferably 90 or less), and it is found that the beer-taste beverage needs to have a concentration of hop component A of 0.24% or more. It was.

The hop component A can be specified under the following conditions when measured by gas chromatography-mass spectrometry (GC / MS method) under the above analytical conditions.
-Corresponds to the peak having an appearance time difference after 10 minutes with respect to the retention time of the internal standard substance borneol.
