Description

低シアン化水素含有量梅酒又は梅酒含有飲料Low-cyanide content plum wine or plum wine-containing beverage
　本発明は、低いシアン化水素含有量を有し、そして特定量でフルフラール及び／又はオクタン酸エチルを含有する梅酒又は梅酒含有飲料、及び関連する方法に関する。 The present invention relates to plum wine or plum wine-containing beverages having a low hydrogen cyanide content and containing specific amounts of furfural and/or ethyl octanoate, and related methods.
　梅酒は、梅果実を焼酎等のアルコール類に添加して製造される飲料であり、酒税法上リキュールに属する。梅酒は、従来から家庭でも作られており、また近年では、醸造メーカーから様々なタイプの梅酒が製造販売されている。 Plum wine is a drink made by adding plums to alcoholic beverages such as shochu, and is classified as a liqueur under the Liquor Tax Act. Plum wine has traditionally been made at home, and in recent years, breweries have begun to produce and sell various types of plum wine.
　近年、梅酒の製造方法について様々な検討がされている。たとえば、特許文献１には、梅の果実を湯煎により加熱してからアルコール液に浸漬して、カルバミン酸エチルの含有量が低い梅酒を製造する方法が開示されている。 In recent years, various studies have been conducted on the production method of plum wine. For example, Patent Document 1 discloses a method of producing plum wine with a low content of ethyl carbamate by heating plum fruits in a hot water bath and then immersing them in an alcoholic solution.

　梅にはシアン配糖体が含まれており、それからシアン化水素が生成し得る。その結果、梅酒や梅酒含有飲料にシアン化水素が含まれる。シアン化水素は通常の梅酒に含まれている程度であれば、人体に影響を与えるものではないが、その量は低下させることができれば好ましい。 Plums contain cyanogenic glycosides, which can produce hydrogen cyanide. As a result, umeshu and beverages containing umeshu contain hydrogen cyanide. Hydrogen cyanide does not have any effect on the human body at the level found in regular umeshu, but it would be preferable if the amount could be reduced.
　シアン化水素含有量を低下させる方法として、原料となる梅酒を希釈する方法が考えられる。
　しかしながら、シアン化水素は、梅の果実に含まれるシアン配糖体から生成されるところ、その生成過程で副生成物として生じるグルコースなどの成分は、梅酒独特の熟成感又は上質なコクに大きく貢献している。そのため、梅酒の希釈の際には、それらの成分の濃度も低下してしまう。したがって、シアン化水素含有量が低い梅酒や梅酒含有飲料では、梅酒独特の熟成感や上質なコクが不足する傾向が強い。 One way to reduce the hydrogen cyanide content is to dilute the plum wine used as the raw material.
However, hydrogen cyanide is produced from cyanogenic glycosides contained in plums, and components such as glucose that are generated as by-products during the production process contribute greatly to the aged feel and rich flavor that is unique to plum wine. Therefore, when plum wine is diluted, the concentrations of these components also decrease. Therefore, plum wine and plum wine-containing beverages with a low hydrogen cyanide content tend to lack the aged feel and rich flavor that is unique to plum wine.
　したがって、本発明の課題は、シアン化水素含有量が低い梅酒や梅酒含有飲料の熟成感又は上質なコクを向上させることである。 The object of the present invention is therefore to improve the aged feel or rich flavor of plum wine or plum wine-containing beverages that have a low hydrogen cyanide content.
　本発明者は、シアン化水素含有量が低い梅酒又はそれを含有する飲料中のフルフラール含有量及び／又はオクタン酸エチルの含有量を特定範囲にすると、その熟成感又は上質なコクを向上させることができることを見出し、本発明を完成させた。 The inventors discovered that by setting the furfural content and/or ethyl octanoate content in plum liquor with a low hydrogen cyanide content or a beverage containing it within a specific range, it is possible to improve the sense of maturity or the rich, refined flavor, and thus completed the present invention.

　以下に実施例に基づいて本発明の説明をするが、本発明はこれらの実施例に限定されるものではない。
　（試験例１）　低シアン化水素含有量飲料に対するフルフラールの効果
　市販されている梅酒製品Ａ（香料を使用している紙パックの梅酒）をコントロールとして用いた（コントロール１）。当該コントロールのシアン化水素含有量はアルコール１００％換算で５ｐｐｍであり、当該コントロールは、９４．６ｐｐｂのフルフラールと１７．５ｐｐｂのオクタン酸エチルを含有していた。次いで、当該コントロールに種々の量のフルフラールを添加して複数の飲料を得た。各飲料のアルコール含有量は、１０～１５ｖ／ｖ％であった。 The present invention will be described below based on examples, but the present invention is not limited to these examples.
(Test Example 1) Effect of furfural on beverages with low hydrogen cyanide content A commercially available plum wine product A (plum wine in a paper carton using flavoring) was used as a control (Control 1). The hydrogen cyanide content of the control was 5 ppm calculated as 100% alcohol, and the control contained 94.6 ppb of furfural and 17.5 ppb of ethyl octanoate. Various amounts of furfural were then added to the control to obtain multiple beverages. The alcohol content of each beverage was 10 to 15 v/v%.
　なお、シアン化水素含有量の測定は、以下のように実施した。すなわち、サンプルとなる飲料にアルカリを添加して、サンプルに含まれる梅由来の加水分解酵素を失活させてから、ｐＨを約５．５に調整し、水蒸気蒸留をして、遊離したシアン化水素をアルカリ溶液中に捕集した。次いで、得られた溶液にピリジンピラゾロン試薬を添加して発色させ、比色法にてシアン化水素の濃度を定量した。続く試験例でも同様にした。 The hydrogen cyanide content was measured as follows. That is, an alkali was added to the sample beverage to inactivate the plum-derived hydrolase contained in the sample, the pH was then adjusted to approximately 5.5, and steam distillation was carried out, after which the liberated hydrogen cyanide was collected in the alkaline solution. Next, a pyridine pyrazolone reagent was added to the resulting solution to develop color, and the concentration of hydrogen cyanide was quantified by colorimetry. The same procedure was followed in subsequent test examples.
　また、各飲料におけるフルフラールとオクタン酸エチルの含有量の測定のためには、以下の条件でＧＣ－ＭＳ分析を実施した。続く試験例でも同様にした。
・分析装置
　Ａｇｉｌｅｎｔ　Ｔｅｃｈｎｏｌｏｇｉｅｓ社製ＧＣＭＳ
・ＧＣオーブン温度条件
　４０℃（５分）－６℃／ｍｉｎ－２４０℃
・カラム
　ＤＢｗａｘ　６０ｍ　内径３２０μｍ　膜厚０．２５μｍ（Ａｇｉｌｅｎｔ　Ｊ＆Ｗ）
・試料前処理　なし In addition, to measure the contents of furfural and ethyl octanoate in each beverage, GC-MS analysis was carried out under the following conditions. The same was done in the subsequent test examples.
Analytical equipment: Agilent Technologies GCMS
GC oven temperature conditions: 40°C (5 min) - 6°C/min - 240°C
Column: DBwax 60m, inner diameter 320μm, film thickness 0.25μm (Agilent J&W)
- No sample pretreatment
　それらの飲料を官能評価に付した。具体的には、各飲料について専門パネル３名が以下の基準にしたがって官能評価し、そのスコアの平均値を求めた（平均値は、四捨五入して整数とした）。評価の個人差を少なくするために、各パネルは、各スコアに対応した標準品を用いて、事前に各スコアと味との関係の共通認識を確立した。この評価方法は、特に断りがない限り、他の試験例でも用いた。 These beverages were then subjected to a sensory evaluation. Specifically, three expert panel members performed a sensory evaluation of each beverage according to the following criteria, and the average score was calculated (the average was rounded off to the nearest integer). To reduce individual differences in evaluation, each panel used a standard product corresponding to each score to establish a common understanding in advance of the relationship between each score and taste. This evaluation method was also used in other test examples, unless otherwise noted.
　＜梅酒含有飲料の熟成感又は上質なコク＞
　　１点：熟成感、上質なコクがない
　　２点：熟成感、上質なコクがあまりない
　　３点：熟成感、上質なコクがやや感じられる
　　４点：熟成感、上質なコクが感じられる
　　５点：熟成感、上質なコクを強く感じられる <The aged feel and refined richness of plum wine-containing beverages>
1 point: No sense of maturity or refined richness 2 points: Not much sense of maturity or refined richness 3 points: Some sense of maturity and refined richness 4 points: A sense of maturity and refined richness is felt 5 points: A strong sense of maturity and refined richness
　フルフラールの含有量と評価結果を表１に示す。フルフラールの含有量が一定範囲にあると、優れた効果が得られた。 The furfural content and evaluation results are shown in Table 1. Excellent effects were obtained when the furfural content was within a certain range.
　（試験例２）　低シアン化水素含有量飲料に対するフルフラールの効果　その２
　梅酒製品Ｂ（香料を使用した糖類ゼロの紙パックの梅酒）をコントロールとして用いたことを除いて試験例１と同様の実験を実施した（フルフラールを添加した飲料の数はより少ないが）。この実験におけるコントロールをコントロール２と呼ぶ。コントロール２におけるシアン化水素含有量はアルコール１００％換算で８ｐｐｍ未満であり、フルフラールの含有量は１９３．３ｐｐｂであり、オクタン酸エチルの含有量は１２．３ｐｐｂであった。また、各飲料のアルコール含有量は８～１２ｖ／ｖ％であった。実験結果を以下に示す。 (Test Example 2) Effect of furfural on low hydrogen cyanide content beverages Part 2
An experiment similar to that of Test Example 1 was carried out, except that plum wine product B (a sugar-free plum wine in a paper carton using flavoring) was used as a control (although the number of beverages to which furfural was added was smaller). The control in this experiment is called Control 2. The hydrogen cyanide content in Control 2 was less than 8 ppm calculated as 100% alcohol, the furfural content was 193.3 ppb, and the ethyl octanoate content was 12.3 ppb. The alcohol content of each beverage was 8-12 v/v%. The experimental results are shown below.
　異なる梅酒を用いても、試験例１と同様の傾向が認められた。このことは、本願発明が幅広い梅酒又は梅酒含有飲料に適用することができることを示唆している。 Even when a different plum wine was used, the same tendency as in Test Example 1 was observed. This suggests that the present invention can be applied to a wide range of plum wines or plum wine-containing beverages.
　（試験例３）　低シアン化水素含有量飲料に対するオクタン酸エチルの効果
　試験例１で用いた梅酒製品Ａをコントロールとして用いた。この試験例では、これをコントロール３と呼ぶ。コントロール３におけるシアン化水素含有量はアルコール１００％換算で５ｐｐｍであり、そのフルフラールの含有量は９４．６ｐｐｂであり、オクタン酸エチルの含有量は１７．５ｐｐｂであった。次いで、当該コントロールに種々の量のオクタン酸エチルを添加して複数の飲料を得た。各飲料のアルコール含有量は１０～１５ｖ／ｖ％であった。それらの飲料を、試験例１と同様の官能評価に付した。 (Test Example 3) Effect of ethyl octanoate on beverages with low hydrogen cyanide content The plum wine product A used in Test Example 1 was used as a control. In this test example, it is called Control 3. The hydrogen cyanide content in Control 3 was 5 ppm calculated as 100% alcohol, the furfural content was 94.6 ppb, and the ethyl octanoate content was 17.5 ppb. Various amounts of ethyl octanoate were then added to the control to obtain a number of beverages. The alcohol content of each beverage was 10-15 v/v%. These beverages were subjected to the same sensory evaluation as in Test Example 1.
　オクタン酸エチル含有量と評価結果を表３に示す。オクタン酸エチルの含有量が一定範囲にあると、優れた効果が得られた。 Table 3 shows the ethyl octanoate content and the evaluation results. When the ethyl octanoate content was within a certain range, excellent effects were obtained.
　（試験例４）　低シアン化水素含有量飲料に対するオクタン酸エチルの効果　その２
　コントロールとして試験例２と同じ梅酒製品Ｂを用いたことを除いて試験例３同様の実験を実施した（オクタン酸エチルを添加した飲料の数はより少ないが）。この実験におけるコントロールをコントロール４と呼ぶ。コントロール４におけるシアン化水素含有量はアルコール１００％換算で８ｐｐｍ未満であり、フルフラールの含有量は１９３．３ｐｐｂであり、オクタン酸エチルの含有量は１２．３ｐｐｂであった。各飲料のアルコール含有量は８～１２ｖ／ｖ％であった。その実験結果を以下に示す。 (Test Example 4) Effect of ethyl octanoate on low hydrogen cyanide content beverages Part 2
An experiment similar to that of Test Example 3 was carried out, except that the same plum wine product B as in Test Example 2 was used as a control (although the number of beverages to which ethyl octanoate was added was smaller). The control in this experiment is called Control 4. The hydrogen cyanide content in Control 4 was less than 8 ppm calculated as 100% alcohol, the furfural content was 193.3 ppb, and the ethyl octanoate content was 12.3 ppb. The alcohol content of each beverage was 8-12 v/v%. The experimental results are shown below.
　異なる梅酒を用いても、試験例３と同様の傾向が認められた。このことは、本願発明が幅広い梅酒又は梅酒含有飲料に適用することができることを示唆している。 Even when a different plum wine was used, the same tendency as in Test Example 3 was observed. This suggests that the present invention can be applied to a wide range of plum wines or plum wine-containing beverages.
