保持されるとの知見を得た。(d) Means for Solving the Problems As a result of various studies to solve the above problems, the present inventors found that coffee extraction is performed by roasting green coffee beans and extracting coffee components from ground coffee beans. Freeze the liquid,
It was discovered that when stored for a long period of time, there is no change in pH, that is, acidity, and there is no change in caffeine, lignin, trigonelline, etc., and the flavor of the coffee drink is retained. Ta.
本発明はこれらの知見に基づき完成されたものである。The present invention was completed based on these findings.
以下、本発明を詳細に説明する。The present invention will be explained in detail below.
本顧請求項1の凍結コーヒーにおいては、コーヒー生豆
を焙煎し、粉砕したコーヒー豆粉からコーヒー成分を抽
出してなるものである。The frozen coffee according to claim 1 is obtained by roasting green coffee beans and extracting coffee components from ground coffee bean powder.
本発明で使用されるコーヒー生豆には特に限定されるも
のではなく、例えばアラビカ種のブラジル、コロンビア
、ペルー、キリマンジャロ等や、ロブスタ種のインドネ
シア、ウガンダ等があり、これらを単独で、或いは複数
ブレンドして使用することができる。The green coffee beans used in the present invention are not particularly limited, and include, for example, Arabica beans of Brazil, Colombia, Peru, Kilimanjaro, etc., and Robusta beans of Indonesia, Uganda, etc., and these may be used singly or in combination. Can be used by blending.
そして、このコーヒー生豆は常法により焙煎されるが、
この焙煎されたコーヒー豆は粉砕される。These green coffee beans are then roasted using conventional methods.
These roasted coffee beans are ground.
この粉砕条件は特に限定されるものではないが、好まし
くは通常10〜40メッシュの粒子が全体の70〜90
%存在するように調節するのが望ましい。The pulverization conditions are not particularly limited, but it is preferable that particles of 10 to 40 mesh account for 70 to 90% of the total.
It is desirable to adjust it so that it exists in %.
この場合、粉砕されたコーヒー豆は、香りや風味の成分
が揮散したり、変質が起こりやすいので、コーヒー豆の
粉砕後はできるだけ速やかに水或いは熱湯で抽出処理す
るのが望ましい。この際、熱湯を用いて抽出処理を行う
ときには、熱に弱い芳香成分の揮散もしくは分解又は変
質の恐れがあり、更に風味を低下させる成分の溶出など
の恐れがあるので、コーヒー豆粉を水に浸漬するのが望
ましい。この浸漬の条件は特に限定されるものではない
がコーヒー飲料の風味を一層上げるために、45℃以下
、好ましくは35℃以下の水で、3分〜180分、好ま
しくは15分〜120分間浸漬すればよい。In this case, since the aroma and flavor components of the ground coffee beans tend to volatilize and deteriorate, it is desirable to extract the coffee beans with water or hot water as soon as possible after the coffee beans are ground. At this time, when performing the extraction process using boiling water, there is a risk of volatilization, decomposition, or deterioration of aromatic components that are sensitive to heat, and there is also a risk of elution of components that reduce the flavor. Immersion is preferable. The conditions for this immersion are not particularly limited, but in order to further enhance the flavor of the coffee beverage, immersion is carried out in water at 45°C or lower, preferably 35°C or lower, for 3 to 180 minutes, preferably 15 to 120 minutes. do it.
この浸漬時間が、3分未満と短い場合には、抽出が不完
全となり、香りや風味の成分の抽出が不充分となり、一
方、180分を超えて浸漬しても、抽出濃度に変化はな
く意味がないだけでなく、芳香成分の揮散もしくは分解
又は変質の恐れがあり、更に風味を低下させる成分の溶
出などの恐れがあるので、いずれの場合も望ましくない
。If this immersion time is short, less than 3 minutes, the extraction will be incomplete and aroma and flavor components will not be extracted sufficiently.On the other hand, even if immersed for more than 180 minutes, there will be no change in the extraction concentration. Not only is it meaningless, but there is also a risk of volatilization, decomposition, or deterioration of the aromatic components, and furthermore, there is a risk of elution of components that degrade the flavor, so either case is undesirable.
この浸漬方法は特に限定されるものではないが、通常、
抽出操作を行う抽出器内で行なわれる。この抽出器の形

香料なども添加してもよい。The coffee extract thus obtained may optionally contain sugar, liquid sugar or fructose, sweeteners such as aspartame, dairy products such as powdered milk, milk, and condensed milk, and further emulsifiers.
Flavoring agents may also be added.
又、このコーヒー抽出液を高温短時間殺菌後、無菌の密
閉容器に充填してもよい。この容器としては特に限定さ

に望ましい。Alternatively, this coffee extract may be sterilized at high temperature for a short time and then filled into a sterile airtight container. The container is not particularly limited, but plastic containers and paper containers are particularly desirable.
そして、本発明においては、上記の方法で得られたコー
ヒー抽出液を速やかに凍結することにより、長期保存を
行ってら風味が失われないのである。この凍結の方法は
特に限定されるものではなく、急速凍結であると、緩慢
凍結であるとを問わない。According to the present invention, by immediately freezing the coffee extract obtained by the above method, the flavor will not be lost even after long-term storage. This freezing method is not particularly limited, and may be rapid freezing or slow freezing.
この凍結コーヒーの飲用にあたっては、加熱容器に入れ
