Description

  The present invention relates to a method for suppressing deterioration of flavor caused by trans-2-nonenal (E2N) or citral deterioration in a beer-taste beverage, a beer-taste beverage produced using the method, and a method for producing the beer-taste beverage About.

  In general, in many beer-taste beverages including beer, sparkling liquor, liqueur, and non-alcohol beer-taste beverages, an unfavorable aroma is generated due to oxidative degradation, and the flavor is greatly impaired. As an indicator of oxidative deterioration of beer-taste beverages, characteristic cardboard odors, undesired sweetness, and powdery taste are recognized. In particular, research on cardboard odor has progressed, and its generation mechanism has become clear, such as E2N being the main cause. Lipids and fatty acids derived from the raw materials undergo both enzymatic and non-enzymatic oxidation during the wort preparation process to form E2N precursors (hydroxide derivatives), which are further oxidatively decomposed into E2N. Change. Citral, which is a component of fresh citrus fragrance, also produces an unpleasant fragrance due to deterioration. Therefore, particularly in the case of a beer-taste beverage containing citrus fragrance, the citral deterioration and E2N generation occur at the same time. Tend to get worse.

  The E2N content of beer-taste beverages can be reduced by preventing oxidation by dissolved oxygen in raw materials, semi-finished products and products in the manufacturing process. Therefore, in order to reduce the amount of dissolved oxygen such as raw materials, control of the wheat making method and control of the charging method have been carried out. For example, supplying a raw material liquid containing malt and raw water to a charging tank in which a part of the raw material water is previously filled with the tip of the raw material liquid supply pipe as low as possible The method of reducing the amount of dissolved oxygen in the charged raw material is mentioned (for example, refer patent document 1).

  On the other hand, as a compound having a refreshing effect, (−)-(1R, 4S, 5R, 6R, 7S, 10R) -7-isopropyl-4,10-dimethyl-tricyclo [4.4.0.0 (1, 5)] decan-4-ol (the following formula (1)) (hereinafter referred to as “cube ball”) (for example, see Patent Document 2). The compound is one of many flavor components contained in natural Kubebu oil, and is characterized by long-lasting refreshing effect although the flavor is very weak. The compound can be isolated from the berries of Piper cube or true cube, and can also be synthesized from an acyclic pyrophosphate terpene precursor by sesquiterpene synthase (see, for example, Patent Document 3).

In the manufacturing process, it is possible to reduce the production of E2N by controlling malting and feeding so as to reduce the chance of contact with oxygen as much as possible, but it is impossible to completely stop the production of E2N. is there.
In addition, although Kubeball has been used in sweet drinks, chewing gums, grapefruit drinks, toothpaste gels, and the like (Patent Document 2), the relationship with oxidation-degraded flavor has never been known.

  The present invention relates to a method for suppressing deterioration of flavor caused by trans-2-nonenal (E2N) or citral deterioration in a beer-taste beverage, a beer-taste beverage produced using the method, and a method for producing the beer-taste beverage The purpose is to provide.

  As a result of diligent research to solve the above-mentioned problems, the present inventors have found that the oxidation deterioration flavor in a beer-taste beverage can be masked by adding kube-ball or δ-casinene, which is a decomposition product thereof. Was completed.

Suppression of flavor deterioration of beer-taste beverages, characterized in that the compound of formula (1) or δ-casinene is added as a raw material so that the δ-casinene content in the manufactured beer-taste beverage is 1.2 ppb or more. Method.

  According to the present invention, it is possible to obtain a beer-taste beverage in which an oxidative deterioration odor caused by trans-2-nonenal or citral deterioration is reduced by using cubet ball or δ-casinene as a raw material.

In the reference example 1, it is the figure which showed the time-dependent change of the Kubeball density | concentration at the time of preserve | saving at 37 degreeC 5 volume% ethanol solution (pH3, 5 and 7) which added 100 ppm of commercially available fragrance | flavor FH12 containing a Kubeball. .

  In the present invention and the present specification, a beer-taste beverage has a taste, taste and texture equivalent to or similar to beer, regardless of the alcohol content or the presence or absence of malt, and a high feeling of thirst / drink mold. It means an effervescent beverage having a tea. That is, the beer-taste beverage may be an alcoholic beverage, or a so-called non-alcoholic beverage or low-alcoholic beverage having an alcohol content of less than 1% by volume. Moreover, the drink which uses malt as a raw material may be sufficient, and the drink which does not use malt as a raw material may be sufficient. Furthermore, it may be a fermented beverage or a non-fermented beverage. Specific examples of beer-taste beverages include beer, sparkling liquor made from malt, sparkling alcoholic beverages that do not use malt, low alcohol sparkling beverages, and non-alcoholic beers. In addition, liqueurs obtained by mixing malt as a raw material and a beverage produced through a fermentation process with an alcohol-containing distillate may be used. The alcohol-containing distillate is a solution containing an alcohol obtained by a distillation operation, and those generally classified as spirits such as spirits can be used.

  Flavor deterioration due to E2N or citral deterioration in beer-taste beverages is caused by Kubéball [(−)-(1R, 4S, 5R, 6R, 7S, 10R) -7-isopropyl-4,10-dimethyl-tricyclo [4. 4.0.0 (1,5)] decan-4-ol (compound of formula (1))] or δ-cadinene can be added as a raw material. Beer-taste beverages are generally acidic at a pH of 5 or less, but cubebole is rapidly decomposed into terpenes containing δ-cadinene at a pH of 5 or less. The reason why flavor deterioration is suppressed by including δ-casinene in a beer-taste beverage is not clear, but oxidation deterioration flavors such as cardboard odor caused by E2N and citral deterioration products are masked by δ-casinene. It is guessed that it is for this purpose.

  Here, KUBE BALL is known as a flavor component having a refreshing effect, but δ-cadinene, which is a decomposition product thereof, is one of sesquiterpenes, and although it has extremely high hydrophilicity, it has a characteristic fragrance. In general, it is not distributed as a fragrance. The fact that δ-Kadinene has a masking effect on the oxidatively deteriorated flavor caused by E2N or citral deterioration is a finding found by the present inventors for the first time.

  The masking effect by δ-Kadinene depends on the δ-Kadinene content in the beer-taste beverage. The amount of cubet balls or δ-casinene added to the beer-taste beverage can be appropriately determined in consideration of the type and composition of the beer-taste beverage, the ease with which an oxidized deterioration flavor is produced, and the like. In many beer-taste beverages, the δ-casinene content in the produced beer-taste beverage is 1.2 ppb or more, preferably 3 ppb or more, more preferably 6 ppb or more, even more preferably 10 ppb or more, and even more preferably 12 ppb or more. Thus, the masking effect on the oxidatively deteriorated flavor can be obtained by adding KUBE BALL or δ-Kadinene. Even if an excessive amount of δ-casinene is added, the masking effect reaches its peak, but δ-casinene itself has a weak flavor, so even if the content is increased, flavors other than the oxidatively deteriorated flavor of the beer-taste beverage The impact on is very small. For example, even when the content of δ-casinene is about 50 ppb, a masking effect on the oxidatively deteriorated flavor can be obtained without impairing the preferred flavor and taste characteristics inherent in beer-taste beverages.

  As a beer-taste beverage that suppresses the deterioration of flavor caused by E2N or citral degradation by adding cubebole or δ-Kadinen as a raw material, beer-taste beverages containing E2N or beer-taste beverages containing citral are preferred, and E2N and citral More preferred is a beer-taste beverage containing both. This is because the masking effect by δ-Kadinene is also exerted on the odor caused by the deterioration of citral. By adding kube-ball or δ-cadinene as a raw material together with a citrus fragrance, flavor deterioration can be remarkably suppressed. Examples of beer-taste beverages containing citral include beer-taste beverages made from citrus juices such as lemon and grapefruit and citrus flavors.

  Each of the cubebole and δ-cadinene used in the present invention may be a synthetic product, or may be extracted and purified from a natural product. Moreover, commercially available fragrance | flavor containing Kube ball | bowl and (delta) kadinene can also be used as it is. Examples of the method for synthesizing the compound include a method of synthesizing from an acyclic pyrophosphate terpene precursor using sesquiterpene synthase as described in Patent Document 3. Moreover, the said compound can also be isolated by a conventional method from the fruit of Pipe cube or true cube (for example, refer patent document 2). In addition, Kube ball is included in Qubeb oil by several percent. Therefore, as long as the desired flavor of the beer-taste beverage is not impaired, in the present invention, kubebu oil may be added so that the δ-casinene content in the produced beer-taste beverage is within a desired range.

  A beer-taste beverage containing δ-casinene can be produced in the same manner as other beer-taste beverage production methods, except that kubebol or δ-cadinene is added at any point in the production process. For example, beer-taste beverages such as beer and happoshu can be produced by the steps of preparation (sugar solution preparation), fermentation, storage, and filtration.

  First, as a preparation step (sugar solution preparation step), a sugar solution is prepared from one or more selected from the group consisting of grain raw materials and sugar raw materials. Specifically, first, a mixture containing at least one of a grain raw material and a sugar raw material and raw water is prepared and heated to saccharify starch such as the grain raw material. As a raw material of the sugar liquid, only the grain raw material may be used, only the sugar raw material may be used, or both may be used in combination. Examples of the grain raw material include barley, wheat, wheat such as malt, beans such as rice, corn, and soybean, and potatoes. The grain raw material can be used as a grain syrup, a grain extract or the like, but is preferably used as a ground grain product obtained by a grinding process. Grain pulverization can be carried out by a conventional method. As the pulverized cereal, a pulverized pulverized product, corn starch, corn grits or the like may be subjected to a treatment usually performed before and after the pulverization treatment. In the present invention, the pulverized grain used is preferably a malt pulverized product. By using a malt pulverized product, a beer-taste beverage with a clearer beer taste can be produced. The malt pulverized product may be any product obtained by germinating barley, for example, Nijo barley, by a conventional method, drying it, and then pulverizing it to a predetermined particle size. Moreover, as a grain raw material used in this invention, one type of grain raw material may be sufficient, and what mixed several types of grain raw material may be sufficient. For example, pulverized malt may be used as the main material, and pulverized rice or corn may be used as the auxiliary material. Examples of the saccharide raw material include saccharides such as liquid sugar.

  You may add grain raw materials etc. and auxiliary materials other than water to the said mixture. Examples of the auxiliary material include hops, dietary fiber, fruit juice, bitters, coloring agents, herbs, and fragrances. Moreover, enzyme agents, such as saccharification enzymes, such as (alpha) -amylase, glucoamylase, and pullulanase, and protease, can be added as needed.

  In the present invention, it is preferable to add citral as an auxiliary material. Citral can also be added as a citrus juice such as lemon or grapefruit or as a citrus flavor. In addition, you may add a citral and the citrus-type fragrance | flavor containing this to the fermented liquid after fermentation, and the filtrate after filtration besides the sugar liquid.

  The saccharification treatment is performed using an enzyme derived from a grain raw material or the like, or an enzyme added separately. The temperature and time during the saccharification treatment take into account the type of cereal raw material used, the proportion of cereal raw material in the total fermentation raw material, the type of enzyme added and the amount of the mixture, the quality of the intended beer-taste beverage, etc. , Adjusted as appropriate. For example, the saccharification treatment can be performed by a conventional method such as holding a mixture containing grain raw materials and the like at 35 to 70 ° C. for 20 to 90 minutes.

  By boiling the sugar solution obtained after the saccharification treatment, a boiled juice (boiled sugar solution) can be prepared. The sugar solution is preferably filtered before boiling, and the obtained filtrate is preferably boiled. Moreover, you may boil this using the thing which added warm water to the malt extract instead of the filtrate of this sugar liquid. The boiling method and its conditions can be determined as appropriate.

  A beer-taste beverage having a desired flavor can be produced by appropriately adding herbs before or during the boiling treatment. In particular, hops are preferably added before or during the boiling process. By boiling in the presence of hops, it is possible to efficiently boil flavor and aroma components of hops including polyphenols. The addition amount of hops, the addition mode (for example, adding in several steps) and the boiling conditions can be determined as appropriate.

  After the preparation process and before the fermentation process, it is preferable to remove protein and other soot produced by precipitation from the prepared broth. The removal of the soot may be performed by any solid-liquid separation process, but in general, the precipitate is removed using a tank called a whirlpool. The temperature of the broth at this time should just be 15 degreeC or more, and is generally performed at about 50-80 degreeC. The broth (filtrate) after removing the koji is cooled to an appropriate fermentation temperature with a plate cooler or the like.

  Next, as a fermentation process, yeast is inoculated into the cooled filtrate to perform fermentation. The cooled filtrate may be subjected to the fermentation process as it is, or may be subjected to the fermentation process after adjusting to a desired extract concentration. The yeast used for fermentation is not particularly limited, and can be appropriately selected from yeasts used for producing alcoholic beverages. Although it may be a top fermentation yeast or a bottom fermentation yeast, it is preferably a bottom fermentation yeast because it can be easily applied to large-scale brewing facilities.

  Moreover, the amount of alcohol produced | generated by fermentation is reduced more by suppressing alcoholic fermentation in a fermentation process. Therefore, particularly when producing a beer-taste beverage having a very low alcohol concentration, such as a non-alcohol beer having an alcohol concentration of less than 1% by volume, it is also preferable to lower the degree of fermentation in the fermentation process.

  Furthermore, as a sake storage process, the obtained fermented liquor is aged in a storage tank, stored and stabilized under a low temperature condition of about 0 ° C., and then filtered as a filtration process. The target beer-taste beverage can be obtained by removing yeast and proteins insoluble in the temperature range. The said filtration process should just be a method which can filter and remove yeast, for example, diatomaceous earth filtration, filter filtration with a filter whose average pore diameter is about 4-5 micrometers, etc. are mentioned.

  Moreover, in order to make it a desired alcohol concentration, you may dilute by performing an appropriate amount of water after filtration. The obtained beer-taste beverage is usually bottled by a filling process and shipped as a product.

  In addition, beer-taste beverages corresponding to liqueurs in the liquor tax law can be produced by mixing with spirits, for example, in the steps after the fermentation step with yeast. The addition of spirits may be before or after addition for adjusting the alcohol concentration. Since the added spirit can produce a beer-taste beverage having a more preferable wheat feeling, wheat spirit is preferable.

  Instead of the fermentation step, the storage step, and the filtration step, the boiled juice prepared in the charging step is filtered, and carbon dioxide gas is added to the obtained filtrate, or carbon dioxide is added to the boiled juice prepared in the charging step. It can also have the carbon dioxide introduction process which filters after adding and collects filtrate. The beer-taste beverage obtained after the carbon dioxide gas introduction step is usually bottled in the filling step and shipped as a product. When the carbon dioxide introduction process filters the broth prepared in the charging step and adds carbon dioxide to the obtained filtrate, the filtration treatment may be performed again after the step and before the filling step. For example, it is preferable that after the boiled juice prepared in the charging step is filtered through diatomaceous earth, carbon dioxide gas is introduced into the collected filtrate, and then a filter filtration process is further performed. By not having a fermentation process with yeast, a beer-taste beverage that does not contain alcohol such as non-alcohol beer can be produced.

  The filtration treatment performed in the carbon dioxide gas introduction step can be performed by a conventional method. Moreover, the addition method of the carbon dioxide gas performed in a carbon dioxide gas introduction process can also be performed by a conventional method.

  After the preparation step and before the carbon dioxide introduction step, soot such as protein produced by precipitation may be removed from the prepared broth in the same manner as before the fermentation step. By performing filtration treatment or carbon dioxide gas introduction treatment after removing the soot in advance, the turbid substances that cause precipitation in the final product can be sufficiently removed.

  Moreover, before the carbon dioxide introduction step, it is preferable to stir and homogenize the broth (when removing the soot before the carbon dioxide introduction step, the soup after removing the soot). The stirring method is not particularly limited, and can be appropriately selected from known stirring methods such as bubbling and stirring with a stirring blade. In particular, when a malt pulverized product is used as a raw material, it is preferable to stir the broth by a bubbling method because the wort odor can be suppressed and a texture, flavor, and taste close to beer can be realized. Examples of the gas used for bubbling include carbon dioxide gas and nitrogen gas. The conditions for bubbling can be appropriately determined in consideration of the capacity and size of the vessel for bubbling, the amount of boiled juice contained therein, etc., but it is preferable to perform the conditions under which the flow rate becomes uniform for a predetermined time. Moreover, it is also preferable to carry out on the conditions which bubbling excessively and boiled juice does not foam. Specifically, it can be performed, for example, at a rate of 2 to 55 liters / minute, preferably 2 to 20 liters / minute per 3000 liters of boiling broth.

  In the production process of beer-taste beverages, the timing of adding KUBE BALL or δ-Kadinene is not particularly limited as long as a sufficient amount of δ-Kadinene can remain in the final product. Since the risk of decomposition or modification of δ-cadinene is small after addition, it is preferable to add Kubeball or δ-Kadinene to the sugar solution after saccharification treatment, the fermentation solution after fermentation, or the filtrate after filtration. More specifically, when added to the sugar solution, it may be added immediately after the saccharification treatment, may be added to the boiled sugar solution (boiled juice), or added to the sugar solution after the precipitate is removed after boiling. Alternatively, it may be added to the cooled sugar solution before yeast inoculation. Further, when carbon dioxide gas is introduced without passing through the fermentation step, it may be added to the sugar solution before carbon dioxide gas introduction, or may be added to the sugar solution after carbon dioxide gas introduction.

  EXAMPLES Next, although an Example and a reference example are shown and this invention is demonstrated further in detail, this invention is not limited to a following example etc.

[Example 1]
The effect on the oxidatively deteriorated fragrance after storage by adding KUBE BALL to beer was investigated.
First, beer was manufactured using the 200L scale preparation equipment. Into the charging tank, 40 kg of malt pulverized product and 160 L of raw water were added, and the mixture in the charging tank was heated according to a conventional method to produce a saccharified solution. The obtained saccharified solution was filtered, and hops were added to the obtained filtrate, followed by boiling to obtain wort (cereal broth). Next, the wort of about 80 to 99 ° C. was transferred to a settling tank to separate and remove the precipitate, and then cooled to about 7 ° C. The cold wort was inoculated with beer yeast, fermented at about 10 ° C. for 7 days, and then aged in a storage tank for 7 days. The fermented liquor after aging was filtered (average pore size: 0.65 μm) to obtain the target beer.

Subsequently, a commercial fragrance containing 0.02% by mass of Kubeball (product name: Taste Improver FH12, manufactured by Nihon Filmmenich) (hereinafter abbreviated as “FH12”) in the obtained beer is 100 ppm. Then, the mixture was stored at 37 ° C. for 1 week (test product A). As a control, beer to which FH12 was not added was similarly stored (test product B).
For both test specimens after storage, the δ-casinene content was measured, and a sensory test was performed using six trained panelists as indicators of oxidative degradation. Analysis of δ-Kadinene was performed by GC / MS. Specifically, first, 10 mL of a test product was adjusted to pH 9 using sodium hydroxide, and then mixed with 40 mL of hexane to perform hexane extraction. Subsequently, the hexane layer after extraction was concentrated to 1 mL by evaporation, and this concentrated solution was subjected to GC / MS.
In sensory evaluation, specifically, both test products were compared, and the one with a stronger oxidative degradation odor was evaluated as more advanced in oxidative degradation.

  The results are shown in Table 1. In the table, “oxidation degradation evaluation (person)” represents the number of people who have evaluated that oxidation degradation has progressed more. “ND” indicates that the concentration of δ-casinene was below the detection limit. As a result, more panelists judged that oxidation degradation had progressed more in test product B that had not been added than in test product A to which FH12 had been added. I knew it could be.

[Example 2]
The influence on the oxidative degradation aroma after storage by adding Kube ball to the sparkling liquor containing a citrus flavor was investigated.
First, a beer-taste beverage (lemon) was prepared in the same manner as in Example 1, except that 10 kg of malt and 30 kg of liquid sugar were used instead of 40 kg of malt, and lemon flavor was added to the filtrate after filtration. Scented sparkling liquor) was produced.
Next, FH12 was added to the resulting sparkling liquor so that the final concentration was 100 ppm, and then stored at 37 ° C. for 1 week (Test Product C). As a control, Happoshu to which FH12 was not added was similarly stored (test product D).

  For both test products after storage, in the same manner as in Example 1, the δ-casinene content was measured, and a sensory test was performed using six trained panelists as indicators. The results are shown in Table 2. As a result, more panelists judged that the oxidative degradation had progressed more in the test product D not added than the test product C added with FH12. It was found that the oxidative degradation odor of beer-taste beverages can be suppressed.

[Example 3]
The effect on the oxidatively deteriorated aroma after storage was examined by adding Kube ball to non-alcohol beer made from soybeans without using wheat-derived ingredients.
First, a beer-taste beverage (non-alcoholic beer) was produced in the same manner as in Example 1 except that soy protein was used instead of 40 kg of malt pulverized product.
Next, FH12 was added to the obtained non-alcohol beer so that the final concentration was 100 ppm, and then stored at 37 ° C. for 1 week. As a control, non-alcohol beer to which FH12 was not added was also stored.
About both test goods after a preservation | save, when it carried out similarly to Example 1, the measurement of (delta) kadinene content and the sensory test which made the oxidation deterioration by six trained panelists an index were carried out, Example 1 and 2 Similarly, there are many panelists who judged that the oxidative deterioration progressed more in the test product not added than in the test product added with FH12, and the non-alcohol beer that does not use malt by adding KUBE BALL It was found that the oxidative degradation odor of can be suppressed.

[Example 4]
The effect of adding δ-Kadinene to beer on the oxidative degradation aroma after storage was investigated.
A beer produced in the same manner as in Example 1 was added with 3 ppm of a δ-cadinene ethanol solution containing 1% by mass of δ-cadinene, and then stored at 37 ° C. for 1 week (Test Article E). As a control, beer to which no δ-kadinene ethanol solution was added was similarly stored (test product F).
For both test specimens after storage, a sensory test was conducted in the same manner as in Example 1 using oxidation trained by six trained panelists as an index. All six were from test specimen E to which δ-cadinene was added. However, it was judged that the test product F which was not added was more oxidatively deteriorated.

[Example 5]
The effect of adding kube ball to beer at various concentrations on the oxidative degradation aroma after storage was investigated.
FH12 was added to beer produced in the same manner as in Example 1 so that the final concentration was 12.5 to 200 ppm, and then stored at 37 ° C. for 1 week (test products G1 to G5). As a control, beer to which FH12 was not added was similarly stored (test product H).
For each test article after storage, in the same manner as in Example 1, a δ-casinene content measurement and a sensory test using oxidative degradation by five trained panelists as indicators were performed. The results are shown in Table 3. In Table 3, “Oxidation degradation evaluation (person)” indicates the number of panelists who evaluated that among the five panelists, each test product was more oxidatively degraded than the test product H without FH12 added.

  As a result, all of the test products G1 to G4 having the δ-casinene concentration of 1.27 ppb or more were oxidatively deteriorated more than the test product H than the panelists evaluated to be oxidatively deteriorated than the test product H. More panelists evaluated that there was no flavor deterioration-inhibiting effect of δ-cadinene. In particular, the test products G1 and G2 having a δ-casinene content of 6.42 ppb or more had less than one panelist who evaluated that the test product H was oxidized and deteriorated.

[Reference Example 1]
FH12 was added to a 5% by volume ethanol solution adjusted to pH 3, 5, or 7 so that the final concentration was 100 ppm, and then stored at 37 ° C. for 1 week. On the first, third, and seventh days after storage, the content of cubebole and the content of δ-cadinene in each solution were measured. The measurement of the content of δ kadinene was performed in the same manner as in Example 1. Similarly to δ-Kadinene, the analysis of Kubéball was performed by adjusting 10 mL of the test product to pH 9 using sodium hydroxide, mixing with 40 mL of hexane, performing hexane extraction, and evaporating the extracted hexane layer by 1 mL. This was concentrated by subjecting it to GC / MS.

  The measurement results are shown in FIG. As a result, at a pH of 5 or less, cuboid balls could hardly be detected, but δ kadinene was detected. At pH 7, the content of KUBE BALL decreased with the passage of the storage period and became undetectable on the seventh day, but the detected amount of δ-Kadinene increased with time. From these results, it was found that at a pH of 5 or less, KUBE BALL is decomposed into δ-Kadinene.

  According to the present invention, a beer-taste beverage with reduced oxidative degradation odor after storage can be obtained. Therefore, the present invention can be used particularly in the beer-taste beverage and its manufacturing field.
