本願は、2022年11月2日に、日本に出願された特願2022-176450号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a storage deterioration inhibitor for suppressing flavor deterioration due to storage of food and beverages that are consumed after being stored for a predetermined period of time within a temperature range of 0°C or higher and 100°C or lower, and a method for suppressing storage deterioration of food and beverages using the storage deterioration inhibitor.
This application claims priority based on Japanese Patent Application No. 2022-176450, filed on November 2, 2022, the contents of which are incorporated herein by reference.
ホットプレートや保温ポット等の恒温維持装置が広く普及しており、喫食可能な状態まで調製された飲食品を恒温維持装置に設置しておき、調製後しばらくしてから喫食する場合が多い。例えば、焙煎コーヒー豆から淹れたコーヒー飲料を、保温ポットに入れた状態で保存し、数時間後に飲む場合がある。しかし、飲食品の種類によっては、このような保存によって風味の低下や酸味の増強といった品質劣化が生じる場合がある。
Constant temperature maintaining devices such as hot plates and thermos pots are widely used, and food and drink that has been prepared to be consumed is often placed in the constant temperature maintaining device and consumed some time after preparation. For example, a coffee drink brewed from roasted coffee beans may be stored in a thermos pot and consumed several hours later. However, depending on the type of food and drink, storage in this manner may result in quality deterioration, such as a loss of flavor or an increase in acidity.
このような加温保存による風味劣化を抑制する方法が、様々な飲食品について報告されている。例えば、加温環境で保管されて販売されるいわゆるホットコーヒー飲料では、長期保存により、発酵臭的な劣化臭が生じることがあり、この劣化臭により、コーヒーらしい風味が損なわれてしまう。そこで、特許文献1には、コーヒーオイルをプロピレングリコール又はその水溶液と接触させ得られたコーヒーオイル抽出液を、焙煎コーヒー豆抽出液に添加することによって、発酵臭的な劣化臭の発生が抑制されたコーヒー飲料を製造できることが開示されている。また、特許文献2には、光、熱、空気、酵素等による飲食品の香味の劣化を、バナバ、グァバ、ウラジロガシ、キンミズヒキ、バラ科植物、ケイヒ及びチョウジからなる群より選ばれる植物の抽出物1種又は2種以上を含有させることによって抑制する方法が開示されている。
Methods for suppressing flavor deterioration caused by such heated storage have been reported for various foods and beverages. For example, so-called hot coffee beverages, which are stored in a heated environment and then sold, may develop a fermentation-like odor of deterioration over long periods of storage, which impairs the coffee-like flavor. Patent Document 1 discloses that a coffee beverage in which the generation of a fermentation-like odor of deterioration is suppressed can be produced by adding a coffee oil extract obtained by contacting coffee oil with propylene glycol or an aqueous solution thereof to an extract of roasted coffee beans. Patent Document 2 also discloses a method for suppressing the deterioration of the flavor of foods and beverages caused by light, heat, air, enzymes, etc., by including one or more extracts of plants selected from the group consisting of banaba, guava, oak, agrimony, plants of the rose family, cinnamon, and clove.

2-エチルピラジンは、ナッツ様の香気を有する香気成分であり、これを飲食品に含有させることにより、酸味が抑制され、味の厚みが増し、風味全体が底上げされる。2-エチルピラジンにより保存劣化抑制効果が得られる理由は明らかではないが、味の厚み増大効果や風味の底上げ効果により、保存により劣化する飲食品の風味が補われ、かつ劣化により増大した酸味成分による影響が抑制されることによって、劣化抑制効果が発揮されると推察される。
2-Ethylpyrazine is an aroma component that has a nutty aroma, and adding it to food and beverages suppresses sourness, deepens the flavor, and improves the overall flavor. The reason why 2-ethylpyrazine has an effect of inhibiting deterioration during storage is unclear, but it is presumed that its effect of increasing flavor and improving flavor compensates for the flavor of food and beverages that deteriorates during storage, and suppresses the effects of sour components that increase with deterioration, thereby exerting its deterioration-inhibiting effect.
保存劣化抑制として飲食品に添加される2-エチルピラジンの量は、飲食品中の2-エチルピラジン濃度が保存劣化抑制効果が奏されるために十分な濃度となる量であれば特に限定されるものではない。例えば、保存劣化抑制剤が2-エチルピラジンを含有する場合、飲食品中の保存劣化抑制剤に由来する2-エチルピラジン濃度が1.7~20000ppb、好ましくは10~1000ppb、より好ましくは50~500ppb、さらに好ましくは50~300ppbとなるように、保存劣化抑制を飲食品に添加することが好ましい。
The amount of 2-ethylpyrazine added to food or beverage as a storage deterioration inhibitor is not particularly limited, so long as the concentration of 2-ethylpyrazine in the food or beverage is sufficient to exhibit the storage deterioration inhibitor effect.

2-Ethyl-4-methylthiazole is an aroma component that has a nutty or coffee-like aroma, and adding it to food and beverages gives them a nutty or roasted flavor and improves the overall flavor. The reason why 2-ethyl-4-methylthiazole has an effect of inhibiting deterioration during storage is unclear, but it is presumed that the deterioration-inhibiting effect is achieved by masking unpleasant flavors such as sourness that arise from storage deterioration through its effect of imparting a nutty or roasted flavor and its effect of inhibiting acidity, and further by compensating for the flavor of food and beverages that deteriorate during storage through its effect of improving flavor.
保存劣化抑制として飲食品に添加される2-エチル-4-メチルチアゾールの量は、飲食品中の2-エチル-4-メチルチアゾール濃度が保存劣化抑制効果が奏されるために十分な濃度となる量であれば特に限定されるものではない。例えば、保存劣化抑制剤が2-エチル-4-メチルチアゾールを含有する場合、飲食品中の保存劣化抑制剤に由来する2-エチル-4-メチルチアゾール濃度が0.2~300ppb、好ましくは1.0~100ppb、より好ましくは1.0~50ppb、さらに好ましくは1.0~10ppbとなるように、保存劣化抑制を飲食品に添加することが好ましい。

Anisyl alcohol is an aromatic component that has a powdery, fruity aroma, and adding it to food and beverages enhances the smoothness of the mouthfeel and the unity of the flavor, while suppressing the sourness and enhancing the sweetness. The reason why anisyl alcohol has an effect of inhibiting deterioration during storage is not clear, but it is presumed that the effect of inhibiting deterioration is exerted by enhancing the smoothness of the mouthfeel and the unity of the flavor, which compensates for the flavor of food and beverages that deteriorate during storage, and suppressing the effects of the increased sourness of the components due to deterioration.
保存劣化抑制として飲食品に添加されるアニシルアルコールの量は、飲食品中のアニシルアルコール濃度が保存劣化抑制効果が奏されるために十分な濃度となる量であれば特に限定されるものではない。例えば、保存劣化抑制剤がアニシルアルコールを含有する場合、飲食品中の保存劣化抑制剤に由来するアニシルアルコール濃度が1~1500ppb、好ましくは10~1000ppb、より好ましくは10~500ppb、さらに好ましくは10~100ppbとなるように、保存劣化抑制を飲食品に添加することが好ましい。
The amount of anisyl alcohol added to food or beverages as a storage deterioration inhibitor is not particularly limited, so long as the concentration of anisyl alcohol in the food or beverage is sufficient to exert the storage deterioration inhibitor effect. For example, when the storage deterioration inhibitor contains anisyl alcohol, it is preferable to add the storage deterioration inhibitor to the food or beverage so that the concentration of anisyl alcohol derived from the storage deterioration inhibitor in the food or beverage is 1 to 1500 ppb, preferably 10 to 1000 ppb, more preferably 10 to 500 ppb, and even more preferably 10 to 100 ppb.
酢酸ベンジルは、フローラル様やフルーツ様の香気を有する香気成分であり、これを飲食品に含有させることにより、口当たりのまろやか感や焙煎感が増強され、かつとがった酸味が抑制される。酢酸ベンジルにより保存劣化抑制効果が得られる理由は明らかではないが、口当たりのまろやか感や焙煎感の増強効果により、保存により劣化する飲食品の風味が補われ、かつ劣化により増大した酸味成分による影響が抑制されることによって、劣化抑制効果が発揮されると推察される。
Benzyl acetate is an aroma component that has a floral or fruity aroma, and adding it to food and beverages enhances the smoothness and roasted taste in the mouth and suppresses sharp acidity. The reason why benzyl acetate has an effect of inhibiting deterioration during storage is unclear, but it is presumed that the effect of inhibiting deterioration is exerted by compensating for the flavor of food and beverages that deteriorates during storage through the effect of enhancing the smoothness and roasted taste, and by suppressing the impact of the acidity components that increase with deterioration.
保存劣化抑制として飲食品に添加される酢酸ベンジルの量は、飲食品中の酢酸ベンジル濃度が保存劣化抑制効果が奏されるために十分な濃度となる量であれば特に限定されるものではない。例えば、保存劣化抑制剤が酢酸ベンジルを含有する場合、飲食品中の保存劣化抑制剤に由来する酢酸ベンジル濃度が1~600ppb、好ましくは10~300ppb、より好ましくは10~100ppb、さらに好ましくは10~50ppbとなるように、保存劣化抑制を飲食品に添加することが好ましい。
The amount of benzyl acetate added to food or beverage as a storage deterioration inhibitor is not particularly limited, so long as the concentration of benzyl acetate in the food or beverage is sufficient to exhibit the storage deterioration inhibitor effect. For example, when the storage deterioration inhibitor contains benzyl acetate, it is preferable to add the storage deterioration inhibitor to the food or beverage so that the concentration of benzyl acetate derived from the storage deterioration inhibitor in the food or beverage is 1 to 600 ppb, preferably 10 to 300 ppb, more preferably 10 to 100 ppb, and even more preferably 10 to 50 ppb.

The effects of various compounds on the deterioration of the aroma and flavor of regular coffee beverages when stored in a pot for 3 hours were investigated. The compounds used were 2-ethylpyrazine, butyl propionate, 2,3-diethyl-5-methylpyrazine, 2-ethyl-4-methylthiazole, anisyl alcohol, and benzyl acetate.
まず、アラビカ種コーヒー豆の焙煎豆(中煎り)を粉砕し、ドリップ式にて熱水で抽出し、コーヒー抽出液を得た。各コーヒー抽出液に、表1に記載の化合物を同じく表中に示す濃度となるように添加した後、ポットに充填して3時間保存した。保存前のコーヒー抽出液をポジティブコントロールとし、表に記載の化合物を添加していないコーヒー抽出液をポットに充填して3時間保存したコーヒー抽出液をネガティブコントロールとした。
First, roasted Arabica coffee beans (medium roast) were ground and extracted with hot water using a drip method to obtain coffee extracts. The compounds listed in Table 1 were added to each coffee extract at the concentrations shown in the table, and then the coffee extracts were poured into a pot and stored for three hours. The coffee extract before storage was used as a positive control, and the coffee extract to which the compounds listed in the table had not been added was poured into a pot and stored for three hours was used as a negative control.
各評価サンプルのコーヒー抽出液について、コーヒーらしい風味について官能評価を行った。官能評価は、トレーニングされた専門パネル3人が行い、10段階(0が最も弱く、9が最も強い。)でスコア付けをした。ネガティブコントロールのコーヒー飲料の評価点を1、ポジティブコントロールのコーヒー飲料の評価点を9とした。各試験区の評価点を表1に示す。評価点が6以上の場合に、保存劣化抑制効果が確認されたと評価した。表中「ポジコン」、「ネガコン」は、それぞれ、ポジティブコントロールのコーヒー飲料及びネガティブコントロールのコーヒー飲料をそれぞれ示す。

Nut milk prepared in the same manner from the peanuts set aside before storage was used as the positive control, and nut milk prepared from the peanuts after storage, to which no storage deterioration inhibitors were added, was used as the negative control. The concentrations of 2-ethylpyrazine, butyl propionate, 2,3-diethyl-5-methylpyrazine, 2-ethyl-4-methylthiazole, anisyl alcohol, and benzyl acetate in each nut milk are shown in Table 8. In the table, "-" means no compounding.
これらのナッツミルクのナッツらしい風味について、官能評価を行った。官能評価は、トレーニングされた専門パネル2人が行い、10段階(0が最も弱く、9が最も強い。)でスコア付けをした。ネガティブコントロールのナッツミルクの評価点を1、ポジティブコントロールのナッツミルクの評価点を9とした。評価点が6以上の場合に、保存劣化抑制効果が確認されたと評価した。各試験区の評価点を表8に示す。表中「ポジコン」、「ネガコン」は、それぞれ、ポジティブコントロールのナッツミルク及びネガティブコントロールのナッツミルクをそれぞれ示す。
A sensory evaluation was conducted on the nutty flavor of these nut milks. The sensory evaluation was conducted by two trained expert panels, who scored them on a 10-point scale (0 being the weakest and 9 being the strongest). The negative control nut milk was given a score of 1, and the positive control nut milk was given a score of 9. A score of 6 or higher was deemed to have confirmed the effect of inhibiting deterioration during storage. The scores for each test plot are shown in Table 8. In the table, "Positive Control" and "Negative Control" refer to the positive control nut milk and the negative control nut milk, respectively.
保存劣化抑制剤を添加した試験区1~4のナッツミルクは、官能評価の評価点が7以上と高く、特にMix1を添加した試験区1のナッツミルクは、保存前のネガティブコントロールと同程度のナッツらしさが感じられ、保存劣化はほとんど感じられなかった。これらの結果から、添加した保存劣化抑制剤Mix1~4はいずれも、ナッツミルクのようなナッツ風味を有するナッツ加工品に対する保存劣化抑制効果を有していることが確認された。
The nut milks from test plots 1 to 4, which contained added preservation deterioration inhibitors, received high sensory evaluation scores of 7 or above. In particular, the nut milk from test plot 1, which contained added Mix 1, tasted as nutty as the negative control before storage, and showed almost no signs of preservation deterioration. These results confirmed that the added preservation deterioration inhibitors Mixes 1 to 4 all have a preservation deterioration inhibitory effect on nut processed products that have a nutty flavor like nut milk.
