Description

本発明は、ハトムギを原料とした醸造酒及びその製造方法に関する。   The present invention relates to a brewed liquor made from pearl barley and a method for producing the same.

ハトムギは、古くから、利尿、排膿、消炎、鎮痛、滋養にきく漢方薬として知られている。ハトムギはまた、浮腫、皮膚の荒れ、イボ、皮膚の異物を取り去り、肌を美しくする、また身体の疼痛、リュウマチ、神経痛を和らげ、人体の抵抗力を高め、強肝作用を有し、抗癌効果があり、整腸作用があり、強精作用を持つとされている。   Barley has long been known as a traditional Chinese medicine for diuresis, drainage, anti-inflammation, analgesia and nourishment. Barley also removes edema, rough skin, warts, skin foreign bodies, beautifies the skin, relieves body pain, rheumatism, neuralgia, increases human resistance, has strong liver action, and anti-cancer It has an effect, has an intestinal regulating action, and is said to have a strong sexual effect.

ハトムギを原料とした飲食物としてはハトムギ茶が広く知られている。しかし、ハトムギ茶を除いては、ハトムギを原料とする飲食物はあまり知られていない。その中でも、 ハトムギを発酵原料として用いたアルコール飲料としては、ハトムギ焼酎(特許文献1)及びハトムギ発泡酒(特許文献2)が知られている。   As a food and drink made from pearl barley, pearl barley tea is widely known. However, with the exception of pearl barley tea, food and drink made from pearl barley are not well known. Among them, pearl barley shochu (Patent Document 1) and barley happoshu (Patent Document 2) are known as alcoholic beverages using pearl barley as a fermentation raw material.

特許文献1に記載のハトムギ焼酎は、ハトムギを含む複数の原料を発酵させ、次いで蒸留することにより製造されたアルコール飲料である。該ハトムギ焼酎は、発酵した酒を蒸留したものであるため、上記原料であるハトムギ中の効能を持つ成分が焼酎側に移行せず、焼酎滓側に残存している可能性が高い。   The pearl barley shochu described in Patent Document 1 is an alcoholic beverage produced by fermenting and then distilling a plurality of raw materials containing pearl barley. Since the barley shochu is obtained by distilling fermented liquor, there is a high possibility that components having the effect in the barley, which is the raw material, do not move to the shochu side and remain on the shochu side.

特許文献2に記載のハトムギ発泡酒は、ハトムギを原料として発酵させているが、アルコール含有量が4%程度である。   Although the pearl barley described in Patent Document 2 is fermented using pearl barley as a raw material, the alcohol content is about 4%.

ハトムギを含む醸造酒としては、ハトムギの殻を取り除き、ハトムギの実を醸造酒等に加えたよく苡仁酒が知られている。

しかし、ハトムギを原料として発酵して得られた醸造酒についてはこれまでに知られていない。このことについて、本発明者らは、ハトムギを原料として常法に従って醸造酒を製造する場合、ハトムギの独特のえぐい性質により醸造酒の風味が劣るために、これまでにハトムギを原料とする醸造酒が製造されなかったと考えた。   However, brewed liquor obtained by fermenting pearl barley as a raw material has not been known so far. In this regard, when producing brewed liquor according to a conventional method using pearl barley as a raw material, since the flavor of the brewed liquor is inferior due to the peculiar properties of pearl barley, brewed liquor using pearl barley as a raw material so far Thought it was not manufactured.

そこで、本発明においては、ハトムギを発酵原料とする、醸造酒として適したアルコール度数を有し、香気成分を多量に含み、かつ口当たりが良い醸造酒及びその製造方法を提供することを解決すべき課題とした。   Therefore, in the present invention, it should be solved to provide a brewed liquor that uses pearl barley as a fermentation raw material, has an alcohol content suitable as a brewed liquor, contains a large amount of aroma components, and has a good taste, and a method for producing the same. It was an issue.

本発明者らは鋭意研究した結果、ハトムギ粉末を水に加えて加熱・ペースト化し、所定の温度で白麹と酒用酵母を組み合わせて発酵することにより、醸造酒として適したアルコール度数を有し、香気成分を多量に含み、かつ口当たりが良い醸造酒を経済的に効率よく製造することができた。さらに、上記醸造酒は、本来ハトムギが有する生体機能性物質を損なうことなく有効に利用した醸造酒である。本発明は、これらの知見に基づいて完成された発明である。   As a result of diligent research, the inventors of the present invention added pearl barley powder to water to form a heat paste, and fermented with a combination of white birch and liquor yeast at a predetermined temperature, thereby having an alcohol content suitable for brewing sake. Thus, a brewed liquor containing a large amount of aroma components and having a good taste could be produced economically and efficiently. Furthermore, the brewed liquor is a brewed liquor that is effectively used without impairing the biologically functional substances inherent to pearl barley. The present invention has been completed based on these findings.

すなわち本発明によれば、ハトムギを原料として発酵して得られる醸造酒であって、エタノール含有量が15.0質量%以上、イソアミルアルコール含有量が100体積百万分率(ppm)以上、及びアセトアルデヒド含有量が500ppm以下である、前記醸造酒が提供される。   That is, according to the present invention, a brewed liquor obtained by fermenting pearl barley as a raw material, having an ethanol content of 15.0% by mass or more, an isoamyl alcohol content of 100 volume parts per million (ppm) or more, and The brewed liquor having an acetaldehyde content of 500 ppm or less is provided.

さらに本発明の別の態様として、ハトムギを水に加えて加熱することによりハトムギペーストを得る工程、及び前記ハトムギペーストを冷却し、次いで白麹及び酒用酵母を加えて28℃以下の温度で発酵させる工程を含む、ハトムギを原料とする醸造酒の製造方法が提供される。   Furthermore, as another aspect of the present invention, a step of obtaining pearl paste by adding pearl barley to water and heating, and then cooling the pearl paste and then adding white birch and liquor yeast and fermentation at a temperature of 28 ° C. or lower A method for producing a brewed liquor using pearl barley as a raw material is provided.

好ましくは、前記酒用酵母が協会7号酒用酵母である。   Preferably, the sake yeast is Association No. 7 sake yeast.

本発明の醸造酒は、香気成分を含んでおり、味が良い。また、活性酸素除去効果がある。さらに、本発明の醸造酒は原料のハトムギの薬効成分はそのまま残存しているので、ハトムギが本来有している人体の抵抗力を高め、強肝作用を有し、抗癌効果、整腸作用があり、活性酸素除去効果があり、抗インフルエンザウイルス活性、ヒト免疫不全ウイルス活性のあることが期待できる。本発明の醸造酒は以上のような効果を有するため、健康飲料として非常に有用である。   The brewed liquor of the present invention contains an aroma component and has a good taste. Also, there is an active oxygen removal effect. Furthermore, since the medicinal component of the raw pearl barley remains as it is in the brewed liquor of the present invention, the resistance of the human body inherent to the pearl barley is increased, it has a strong liver action, an anticancer effect, an intestinal action And has an effect of removing active oxygen, and can be expected to have anti-influenza virus activity and human immunodeficiency virus activity.
