Definitions
- the present invention relates to a container-packed coffee drink. More specifically, the present invention relates to a container-packed coffee beverage in which bitterness is suppressed regardless of the liquid temperature and a good aftertaste sharpness, a method for producing the coffee beverage, and the like.
- Coffee coffee is widely loved as a luxury product, and the demand for it is increasing and the needs are diversifying. For example, while there is a need for a coffee beverage having a bitter taste that is unique to coffee, there is also a need for a coffee beverage having a good aftertaste and a bitter taste that is unique to coffee.
- various types of coffee beverages from warming beverages to beverages for room temperature storage. Under such circumstances, the consumer can select a coffee drink in a product form according to his / her preference, drinking place, drinking time and other consumption modes. For example, there are also widespread modes of drinking coffee drinks while walking or drinking coffee drinks over time during work or breaks.
- Non-Patent Document 1 It has been reported that in coffee beverages, some fragrance components decrease with the passage of time after production and the fragrance balance of the coffee beverage changes (Non-Patent Document 1), which contributes to the fragrance of the coffee beverage.
- Patent Document 2 There have also been reports of attempts to suppress changes in the aroma balance of coffee beverages over time by adding ingredients.
- 2-furfurylthiol, 3-mercapto-3-methylbutylformate, 3-methyl-2-butene-1-thiol, etc. which are components that particularly contribute to the fresh scent of coffee, It has been reported that it disappears rapidly after drowning (Non-patent Document 2).
- Non-Patent Document 3 reports that 2-furfurylthiol is a particularly important component for imparting fresh sensation, but binds to melanoidin, which is a water-soluble component of coffee, and disappears particularly rapidly. ing.
- heat sterilization of canned coffee beverages also reduces the amount of aroma components such as 2-furfuryl thiol and 3-mercapto-3-methylbutyl formate, and 2-furfuryl thiol is the pH of ordinary coffee beverages. It has also been reported that the ratio is significantly reduced (around 6) (Non-Patent Document 4).
- Patent Document 1 by controlling the mass ratio of pyrazines and guaiacols in a coffee drink to a specific range, a coffee extract rich in sweet aroma and having a good aftertaste can be obtained.

本発明の一態様は、グアイアコール及びフルフリルメチルスルフィドの含有量が特定の範囲内にある、容器詰めコーヒー飲料である。これにより、飲料の液温にかかわらず、苦味を抑制でき、後味のキレが良好な容器詰めコーヒー飲料を提供できる。また、苦味が抑制され、後味のキレが良好であることから、飲みやすく、ドリンカビリティの高いコーヒー飲料を提供することができる。なお、本明細書において「苦味」とは、コーヒー特有の後引きする舌に残る苦味であり、後味のキレに影響するものをいう。苦味のあるコーヒー飲料は後味のキレが悪く、苦味が抑制されたコーヒー飲料は後味のキレが良好である。また、「ドリンカビリティ」とは、負担なく・飲みやすい味わいの性質のことをいう。
グアイアコールはコーヒー特有の苦味に寄与する成分である。なお、本明細書では、グアイアコールを(a)と表記する場合がある。
フルフリルメチルスルフィドは一般的にはコーヒー特有の深煎り香を有する成分として知られているが、本発明においては常温(20℃前後)において特異的にコーヒー飲料の苦味抑制効果を有する成分である。なお、本明細書では、フルフリルメチルスルフィドを(p)と表記する場合がある。
本発明において、p-エチルフェノール、p-クレゾール、フェノール及び2-アセチルピロールは、いずれもコーヒー特有の苦味に寄与する成分である。本発明のコーヒー飲料では、コーヒー特有の苦味を効果的に抑制する観点から、さらに、p-エチルフェノール、p-クレゾール、フェノール及び2-アセチルピロールからなる群から選択される一以上の成分の含有量を特定の範囲に調整することもできる。なお、本明細書では、p-エチルフェノール、p-クレゾール、フェノール及び2-アセチルピロールを、それぞれ(b)、(c)、(d)、及び(e)と表記する場合がある。
本発明において、フルフリルメルカプタン、フルフリルメチルジスルフィド及びフルフリルチオアセテートは、いずれも一般的にはコーヒー特有の深煎り香を有する成分として知られているが、本発明においては、フルフリルメチルスルフィドと同様に、常温(20℃前後)において特異的にコーヒー飲料の苦味抑制効果を有する成分である。本発明のコーヒー飲料では、効果的に常温(20℃前後)におけるコーヒー飲料の苦味を抑制するという観点から、さらにフルフリルメルカプタン、フルフリルメチルジスルフィド、及びフルフリルチオアセテートからなる群から選択される一以上の成分の含有量を特定の範囲に調整することもできる。
本発明のコーヒー飲料は、飲料の液温にかかわらず、苦味を抑制し、後味のキレを良好にするという観点から、グアイアコール(a)、p-エチルフェノール(b)、p-クレゾール(c)、フェノール(d)、又は2-アセチルピロール(e)の含有量と、フルフリルメチルスルフィド(p)含有量との比率が特定の範囲にあることが好ましい。例えば、とフルフリルメチルスルフィド(p)とグアイアコール(a)との含有量比[(p)/(a)]は、1.5>[(p)/(a)]>0.01であることが好ましく、0.8>[(p)/(a)]>0.05であることがより好ましい。また、フルフリルメチルスルフィド(p)とp-エチルフェノール(b)との含有量比[(p)/(b)]は、40>[(p)/(b)]>0.5であることが好ましく、32>[(p)/(b)]>1.3であることがより好ましい。また、フルフリルメチルスルフィド(p)とp-クレゾール(c)との含有量比[(p)/(c)]は、20>[(p)/(c)]>0.5であることが好ましく、16>[(p)/(c)]>1.3であることがより好ましい。また、フルフリルメチルスルフィド(p)とフェノール(d)との含有量比[(p)/(d)]は、1.0>[(p)/(d)]0.01であることが好ましく、0.6>[(p)/(d)]>0.02であることがより好ましい。さらに、フルフリルメチルスルフィド(p)と2-アセチルピロール(e)との含有量比[(p)/(e)]は、0.5>[(p)/(e)]>0.01であることが好ましく、0.2>[(p)/(e)]>0.02であることがより好ましい。
本明細書において「コーヒー飲料」とは、コーヒー分を原料として使用し、加熱殺菌処理がなされた飲料製品のことをいう。製品の種類は特に限定されないが、1977年に認定された「コーヒー飲料等の表示に関する公正競争規約」の定義である「コーヒー」、「コーヒー飲料」、及び「コーヒー入り清涼飲料」が主に挙げられる。また、コーヒー分を原料とした飲料においても、乳固形分が3.0重量%以上のものは「飲用乳の表示に関する公正競争規約」の適用を受け、「乳飲料」として取り扱われるが、これも、本発明におけるコーヒー飲料とする。ここで、コーヒー分とは、コーヒー豆由来の成分を含有するものをいい、例えば、コーヒー抽出液、即ち、焙煎、粉砕されたコーヒー豆を水や温水などを用いて抽出した溶液が挙げられる。また、コーヒー抽出液を冷凍したコーヒーエキス、コーヒー抽出液を乾燥したインスタントコーヒーなどを、水や温水などで適量に調整した溶液も、コーヒー分として挙げられる。
Brix値は、糖度計や屈折計などを用いて20℃で測定された屈折率を、ICUMSA(国際砂糖分析法統一委員会)の換算表に基づいてショ糖溶液の質量/質量パーセントに換算した値であり、飲料中の可溶性固形分含有量を表す。単位は「Bx」、「%」、又は「度」と表記する場合もある。飲料のBrix値が低ければ、糖質を含めた飲料中の可溶性固形分の含有量が低いこととなる。
本発明のコーヒー飲料では、上記成分の他、本発明の効果を損なわない限りで、甘味料(ショ糖、異性化糖、ブドウ糖、果糖、乳糖、麦芽糖、キシロース、異性化乳糖、フラクトオリゴ糖、マルトオリゴ糖、イソマルトオリゴ糖、ガラクトオリゴ糖、カップリングシュガー、パラチノース、マルチトール、ソルビトール、エリスリトール、キシリトール、ラクチトール、パラチニット、還元デンプン糖化物、ステビア、グリチルリチン、タウマチン、モネリン、アスパルテーム、アリテーム、サッカリン、アセスルファムK、スクラロース、ズルチンなど)、酸化防止剤(ビタミンC、エリソルビン酸ナトリウムなど)、乳化剤(ショ糖脂肪酸エステル、ソルビタン脂肪酸エステル、ポリグリセリン脂肪酸エステルなど)、カゼインNa、香料(コーヒーフレーバー、ミルクフレーバーなど)等を適宜配合することができる。本発明のコーヒー飲料では、グアイアコール及びフルフリルメチルスルフィドの濃度を特定範囲に調整するという点から、特に香料を配合することが好ましい。また、本発明の飲料は甘味料により本発明の効果が損なわれる可能性があるので、甘味料を含有しないコーヒー飲料が好ましい。
本発明のコーヒー飲料は、所定の範囲内のpHを有することが好ましい。pHの調整には一般的なpH調整剤を使用することができ、そのようなpH調整剤としては水酸化ナトリウム、水酸化カリウムなどの塩基や、炭酸水素ナトリウム、炭酸ナトリウム、炭酸水素カリウム、炭酸カリウム、リン酸水素二ナトリウム、クエン酸ナトリウム、クエン酸カリウム、酢酸ナトリウム、酢酸カリウム、L-アスコルビン酸ナトリウムなどの有機酸のナトリウム又はカリウム塩、及び、その他食品衛生法上使用可能なpH調整剤又は酸味料が挙げられる。また、pHの異なるコーヒー抽出液を混合することにより所定のpHに調整することも可能である。
ある態様では、本発明は容器詰めコーヒー飲料の製造方法である。より具体的には、本発明の一態様は容器詰めコーヒー飲料の製造方法であって、(i)飲料中のグアイアコール含有量を10~600μg/Lに調整する工程、(ii)飲料中のフルフリルメチルスルフィド含有量を22~1000μg/Lに調整する工程、及び(iii)容器詰めする工程、
を含む、前記製造方法である。
