【発明の属する技術分野】
本発明は、新しい香味を持つ蒸留酒製品、すなわち蒸留酒、及びその加工品、及び当該蒸留酒の製造方法に関する。
【0002】
【従来の技術】
2−アセチル−1−ピロリン(以下、2APと略す)は、アール.ジー.バッテリー(R.G.Buttery)らにより香り米中の主要香気成分であると報告され〔ケミストリー アンド インダストリー(Chemistry andIndustry)、1982、第958頁(1982)〕、その他パン、ポップコーンなど多くの食品中にその存在が明らかにされている。2APは、食品の香気成分として微量で効果を発揮することから、近年、工業的レベルでの2APの製造法が、特許第2562267号公報に開示され、パン製造などへの応用が検討されつつある。また、米の品種の中で2APを豊富に含む香り米は、その独特な香により、世界中で高価な値段で流通している。日本では、その香は毀誉褒貶の差が激しく、香り米が良い米という一般的な認知は薄い。しかし、近年のグルメブームにより、香り米の需要は増加している。
しかしながら、今までに2APを豊富に含有する酒類の報告例はない。2APは比較的不安定な物質であり、特に酒類製造工程における蒸し米工程や発酵工程での揮散などにより、生成した2APを安定に保持することは困難であった。清酒で試みられた例があるが、官能的に2APの特徴を持った清酒の製造には成功していない(技術幹部養成上級研修通信教育テキスト、第24単元「清酒の将来展望」、日本酒造組合中央会、平成11年6月新訂2版発行、第34頁)。
【0003】
【発明が解決しようとする課題】
本発明の第1の目的は、2APを豊富に含み香味に優れた米焼酎及びその加工品を提供することであり、第2の目的は、第1の目的の米焼酎の製造方法を提供することである。これらの目的を達成することによって、米焼酎の酒質の多様化に貢献することができる。
【0004】
【課題を解決するための手段】
本発明を概説すれば、本発明の第1の発明は、2APを0.2ppb〜2ppbの濃度範囲で含むことを特徴とする米焼酎に関し、第2の発明は、原料として米を用い、原料の少なくとも一部を280℃〜350℃で30秒〜2分間焙炒処理する工程及び生成した蒸留前の醪のpHを、4.5〜7.0に管理しながら蒸留する工程を含むことを特徴とする第1の発明の米焼酎の製造方法に関する。
【0005】
本発明者らは、前記従来技術の問題点を解決するため鋭意研究を行った結果、蒸留酒の原料の中で、例えば、精白米を240〜400℃の高温で焙炒処理することにより、焙炒後の米中に2APを増加あるいは保持することに成功した。この焙炒処理法を用いれば、2APが揮散する恐れのある蒸し米工程を省略することが可能となり、2APを有効に醪中に保持することができた。更に、この醪を蒸留し焼酎を製造する場合には、蒸留前の醪のpHを4.5から7.0に管理すると、より多くの2APを焼酎中に移行することができた。これらの知見を基に、蒸留酒中における官能的に好ましい2AP含量の範囲を特定することができ、本発明の完成に至った。
【0006】
【発明の実施の形態】
以下、本発明を具体的に説明する。
本発明における米焼酎の加工品とは、例えば米焼酎を加工したチュウハイなどのリキュール類及び調味料などをいう。
【0007】
本発明における米焼酎において、新規の香ばしい豊かな香を持ち、良好な酒質を与える2APの好ましい範囲は、0.2ppb〜2ppbである。
【0008】
本発明における米焼酎の原料米においては品種には特に限定されず、香り米(高知県産、高育香37号)といわれるような米を用いてもよい。米の精白歩合についても、玄米から高精白米まで、広い範囲の精白歩合のものを用いてもよい。
【0009】
本発明における焙炒処理とは、特許第1816776号公報に開示されているように、穀類及び/又は穀類を水に浸漬したものを、240〜400℃の乾燥した熱風で数秒〜5分間処理すること、又は同等の効果を有する加熱処理のことをいう。より多くの2APを生産させ、官能的に良好な処理条件として、280℃〜350℃で30秒〜2分間の条件を用いることが好ましい。例えば焼酎を製造する場合、350℃、2分間を超える条件で焙炒処理した原料を用いると、焼酎中にやや異なった嫌みのある香がつき、本発明でいう良好な香味を持った焼酎にならない場合がある。
【0010】
次に蒸留する前の醪のpHを4.5から7.0に管理する方法について述べる。具体的には、例えば醪に炭酸カルシウムなどの除酸剤を添加する方法があるが、これに限定されるものではない。
【0011】
焼酎の製造方法であるが、麹については通常の方法で製造した麹を用い、掛原料については少なくとも一部に上述の加熱処理法で処理した原料を用いる。仕込方法は、特許第2886252号公報に記載されている一次、二次で仕込む2段仕込法でもよいし、添、仲、留の3段仕込法でもよい。その後、発酵、蒸留、精製工程を経て製造される。
【0012】
蒸留酒の加工品であるチュウハイの製造方法は、例えば上述した焼酎と糖類などの物品とを混合する工程、及びろ過精製する工程からなる。
【0013】
本発明における蒸留酒、その加工品及び原料中の2APの濃度の測定には、例えば内部標準にシクロヘキサノールを用いたガスクロマトグラフ−質量分析法(以下、GC−MS法と称する)を用いることができる。
【0014】
分析サンプルの前処理は、その種類に応じて適当な方法を用いる。例えば、サンプルが穀類、蒸し米及び炊飯米の場合は、熱エタノール抽出、酸性下での濃縮、ODSカラムの通過、ジエチルエーテル洗浄、中性でのジエチルエーテル抽出及び濃縮の各工程を順次行うことで分析用サンプルを調製する。また、サンプルが蒸留酒の場合は、酸性下での濃縮、ジエチルエーテル洗浄、中性下でのジエチルエーテル抽出及び濃縮工程を経て分析サンプルとする。
【0015】
原料の焙炒処理条件と2APの生成量との関係を検討した例を示す。
【0016】
(検討例1)
原料は一般米を用い70%精白を行い焙炒処理実験に供した。この70%精白米を洗米、浸漬後、水分を28.4%に調整し、180〜280℃の熱風下、45〜100秒間焙炒処理し、処理後の2AP量及び水分量を分析した。また、同じ精白米を洗米、浸漬後、50分間蒸した米についても同様に分析した。
その結果を表1に示す。
【0017】
【表1】
【0018】
表1より、温度が低い180℃及び210℃、45秒の条件では、2APは処理前とほとんど変らず0.39ppbであった。240℃以上の条件になれば2APの増加がみられ、280℃、45秒では4.21ppbの濃度に達した。更に280℃で100秒間処理したものは、2APは9.52ppbになった。したがって、所定の2AP濃度にするためには、240〜400℃で数秒〜5分間処理すればよく、好ましくは280〜350℃で30秒〜2分間加熱処理を行う。また、蒸した米は、0.23ppbと処理前の原料米より低くなっており、蒸し処理は2APの生成には不適当であった。
【0019】
【実施例】
以下、実施例によって本発明を更に具体的に説明するが、本発明がこれらの実施例に限定されるものではない。

BACKGROUND OF THE INVENTION
The present invention relates to a distilled liquor product having a new flavor, that is, a distilled liquor, a processed product thereof, and a method for producing the distilled liquor.
[0002]
[Prior art]
2-acetyl-1-pyrroline (hereinafter abbreviated as 2AP) is R. Gee. RG Buttery et al. Reported that it is a major aroma component in scented rice (Chemistry and Industry, 1982, p. 958 (1982)), and other foods such as bread and popcorn. The existence is revealed. Since 2AP is effective as a fragrance component of food in a very small amount, in recent years, a manufacturing method of 2AP at an industrial level is disclosed in Japanese Patent No. 2562267, and its application to bread production and the like is being studied. . In addition, scented rice rich in 2AP among rice varieties is distributed at high prices all over the world due to its unique incense. In Japan, the incense has a great difference in honor, and the general perception that fragrant rice is good is weak. However, due to the recent gourmet boom, demand for scented rice has increased.
However, there have been no reports of alcoholic beverages containing abundant 2AP so far. 2AP is a relatively unstable substance, and it has been difficult to stably maintain the produced 2AP due to, for example, volatilization in a steamed rice process or a fermentation process in a liquor production process. There have been examples of sake, but it has not been successful in producing sake with the characteristics of 2AP (Senior Management Training Advanced Training Correspondence Textbook, Unit 24 "Sake's Future Outlook", Nippon Sake Brewery (Union Chukaikai, 2nd edition issued in June 1999, page 34).
[0003]
[Problems to be solved by the invention]
The first object of the present invention is to provide a rice shochu rich in 2AP and excellent in flavor, and a processed product thereof. The second object is to provide a method for producing rice shochu of the first object. That is. By achieving these objectives, it can contribute to diversification of the quality of rice shochu liquor.
[0004]
[Means for Solving the Problems]
In summary, the first invention of the present invention relates to rice shochu characterized by containing 2AP in a concentration range of 0.2 ppb to 2 ppb . The second invention uses rice as a raw material, Including a step of roasting at least a part of the mixture at 280 ° C. to 350 ° C. for 30 seconds to 2 minutes and a step of distilling while controlling the pH of the pre-distilled koji at 4.5 to 7.0. It is related with the manufacturing method of the rice shochu of 1st invention characterized by the above-mentioned.
[0005]
As a result of diligent research to solve the problems of the prior art, the present inventors, for example, by roasting polished rice at a high temperature of 240 to 400 ° C. in the raw materials of distilled liquor, We succeeded in increasing or retaining 2AP in the roasted rice. If this roasting method was used, it was possible to omit the steamed rice process in which 2AP could be volatilized, and 2AP could be effectively held in the koji. Furthermore, when this shochu was distilled to produce shochu, more 2AP could be transferred into the shochu by controlling the pH of the soot before distillation from 4.5 to 7.0. Based on these findings, a functionally preferable range of 2AP content in distilled liquor can be specified, and the present invention has been completed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be specifically described below.
The processed products of rice shochu in the present invention, refers to, for example, liqueurs such as Chuuhai processing the rice shochu and seasoning.
[0007]
Te US shochu odor in the present invention has a novel fragrant rich incense, preferred ranges of 2AP provide good Sakeshitsu is 0.2Ppb~2ppb.
[0008]
In the raw materials the United States of rice shochu in the present invention is not particularly limited to the varieties, fragrant rice (Kochi Prefecture, KoIkuKaoru No. 37) rice may be used, such as is said to be. As for the milling rate of rice, a wide range of milling rates from brown rice to highly polished rice may be used.
[0009]
As disclosed in Japanese Patent No. 1816776, the roasting treatment in the present invention is a treatment of immersing cereals and / or cereals in water with dry hot air at 240 to 400 ° C. for several seconds to 5 minutes. Or a heat treatment having an equivalent effect. More 2AP is produced, and it is preferable to use conditions of 280 ° C. to 350 ° C. for 30 seconds to 2 minutes as processing conditions that are functionally good. For example, when producing shochu, if the raw material roasted at 350 ° C. for more than 2 minutes is used, the shochu has a slightly different dislike in the shochu, and the shochu with a good flavor as referred to in the present invention. It may not be possible.
[0010]
Next, a method for controlling the pH of the soot before distillation from 4.5 to 7.0 will be described. Specifically, for example, there is a method of adding a deoxidizer such as calcium carbonate to the koji, but the method is not limited to this.
[0011]
Although it is a manufacturing method of shochu, the soot produced by the usual method is used for the soot, and the raw material processed by the above-mentioned heat treatment method is used for at least a part of the hanging raw material. The charging method may be a primary or secondary charging method described in Japanese Patent No. 2886252 or a three-stage charging method of Soe, Naka and Toru. Then, it is manufactured through fermentation, distillation and purification steps.
[0012]
The method for producing Chu Hai, which is a processed product of distilled liquor, includes, for example, a step of mixing the above-mentioned shochu and an article such as sugar, and a step of filtration purification.
[0013]
For the measurement of the concentration of 2AP in the distilled liquor, its processed products and raw materials in the present invention, for example, gas chromatography-mass spectrometry (hereinafter referred to as GC-MS method) using cyclohexanol as an internal standard is used. it can.
[0014]
The pretreatment of the analysis sample uses an appropriate method depending on the type. For example, if the sample is cereal, steamed rice, and cooked rice, perform the steps of hot ethanol extraction, acid concentration, ODS column passage, diethyl ether washing, neutral diethyl ether extraction and concentration. Prepare a sample for analysis. Moreover, when the sample is distilled liquor, the sample is subjected to concentration under acidic conditions, washing with diethyl ether, extraction with diethyl ether under neutrality, and concentration steps to obtain an analysis sample.
[0015]
The example which investigated the relationship between the roasting process conditions of a raw material and the production amount of 2AP is shown.
[0016]
(Examination example 1)
The raw material was 70% whitened using general rice and subjected to a roasting experiment. After 70% polished rice was washed and immersed, the water content was adjusted to 28.4%, roasted under hot air at 180 to 280 ° C. for 45 to 100 seconds, and the amount of 2AP and the amount of water after the treatment were analyzed. In addition, the same polished rice was washed, soaked and then steamed for 50 minutes for analysis.
The results are shown in Table 1.
[0017]
[Table 1]
[0018]
From Table 1, under the conditions of 180 ° C. and 210 ° C. and 45 seconds where the temperature was low, 2AP was 0.39 ppb, almost unchanged from that before the treatment. When the temperature was 240 ° C. or higher, an increase of 2AP was observed, and the concentration reached 4.21 ppb at 280 ° C. for 45 seconds. Furthermore, 2AP of what was processed at 280 ° C. for 100 seconds was 9.52 ppb. Therefore, in order to obtain a predetermined 2AP concentration, the treatment may be performed at 240 to 400 ° C. for several seconds to 5 minutes, and preferably, heat treatment is performed at 280 to 350 ° C. for 30 seconds to 2 minutes. Moreover, the steamed rice was 0.23 ppb, which is lower than the raw rice before the treatment, and the steaming treatment was inappropriate for the production of 2AP.
[0019]

[0020]
(Reference Example 1) Sample preparation method Extraction and concentration of 2AP in distilled liquor were carried out by the following method. For example, 1M citric acid solution was added to 400 ml of shochu to adjust the pH to 3.0. This liquid was concentrated with an evaporator, and water was added to make 50 ml. After washing twice with an equivalent amount of diethyl teeter, 1M sodium phosphate buffer (pH 6.7) was added to the aqueous phase, and further adjusted to pH 7.0 by adding sodium hydroxide solution, and twice with an equivalent amount of diethyl ether. Extracted. 200 μl of 50 ppm cyclohexanol as an internal standard was added thereto, dried over anhydrous sodium sulfate, and then diethyl ether was distilled off on a 42 ° C. hot bath and concentrated. This was further concentrated to about 200 μl with a nitrogen stream to obtain a GC-MS analysis sample.
[0021]
The pretreatment of the processed product of koji and distilled liquor was performed according to the following method. For example, 1M sodium phosphate buffer (pH 6.7) was added to 400 ml of koji, and sodium hydroxide solution was further added to adjust the pH to 7.0. This solution was put into a 2 liter volume type flask, 200 ml of 99.5% ethanol was added, and then attached to an evaporator, and distilled under reduced pressure on a 40 ° C. warm bath to obtain a distillate. Cooling was performed at 5 ° C. or less, and 50 ml of 1% citric acid aqueous solution was previously added to the bottom of the receiving flask and distilled. Thereafter, it was prepared using the method after the pH 7.0 diethyl ether extraction step of the 2AP extraction concentration method in the above shochu.
[0022]
The 2AP extraction and concentration of raw cereals, steamed rice, and cereals after roasting were performed according to the following method. As pretreatment, about 50 g of raw materials and roasted raw materials were pulverized with a pulverizer, and about 50 g of steamed rice was similarly pulverized after freezing with liquid nitrogen. The total amount of these crushed samples was placed in a 1 liter eggplant type flask, and a total of 300 ml was added while washing with 99.5% ethanol. A 5 ° C. cooling tube was attached to the upper part of the eggplant-shaped flask and refluxed in an 88 ° C. warm bath for 1 hour, followed by filtration with filter paper. To this filtrate, 300 ml of an aqueous citric acid solution (pH 3.0) was added and stirred, and further 1M citric acid was added to adjust to pH 3.0. After concentrating this liquid with an evaporator, water was added to 35 ml, and two ODS-A cartridges 200 mg / 3 ml (manufactured by Daiso) connected in series were passed through and mixed with 15 ml of water washing liquid. This solution was washed twice with an equivalent amount of diethyl ether. Thereafter, it was prepared using the method after the pH 7.0 diethyl ether extraction step of the 2AP extraction concentration method in the above shochu.
[0023]
