DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a coffee beverage such as black coffee and milk coffee.

[0002]

2. Description of the Related Art Conventionally, coffee beverages filled in cans are prepared by mixing powder obtained by crushing roasted coffee beans at a predetermined ratio for each type of coffee beans, thereby obtaining a single extraction. It is manufactured by storing it in a tank and extracting it with hot water.

[0003] The conventional production method will be described in more detail. First, coffee beans roasted at a predetermined roasting degree and pulverized coffee powder, for example, 100 kg for four varieties of Colombia, Guatemala, Brazil and Mocha In each case, a total of 400 kg was stored in a single extraction tank and stirred,
Mix. Next, hot water at 90 to 95 ° C. is showered in the extraction tank, and the whole coffee powder leveled by the mixing is immersed in the hot water. Then, when the whole coffee powder is immersed in the hot water, the coffee extract is taken out from the lower part of the extraction tank while further continuing the hot water showering. The coffee extract is extracted, for example, in an amount of 7 times the weight of the coffee powder.

[0004] The coffee extract is filtered to remove impurities such as coffee powder and the like, cooled to 25 to 30 ° C, and further added with a pH adjuster such as sodium bicarbonate and pure water and mixed. Then, it is made into a coffee beverage and filled in a can or the like. Further, the coffee beverage may be, if desired, the pure water,
A milk-containing coffee beverage may be prepared by adding a milk component such as milk or skim milk powder and an emulsion stabilizer together with the pH adjuster to the coffee extract and mixing.

[0005] In coffee drinks manufactured by the above-mentioned conventional manufacturing method, the taste is adjusted mainly by varying the amount of coffee powder for each variety at the stage before extraction and blending. Here, among the tastes of coffee,
Sweetness and sourness vary depending on the coffee bean's locality and variety
It is known that aroma and bitterness generally vary depending on the degree of roasting represented by the L value.

It is said that the smaller the number, the deeper the roasting and the bitterness peculiar to coffee appears, and the larger the number, the shallower the roasting and the fragrance. Further, it is considered that it is suitable to shorten the extraction time when the L value is small, and to lengthen the extraction time when the L value is large, and to perform the extraction carefully. Therefore, usually, coffee beans having an L value of 15 to 35 are used for the production of coffee beverages, and a roasting degree of 18 to 32 is considered to be suitable.

However, in the conventional manufacturing method,
There is an inconvenience that it is not possible to extract all of the blended coffee powders at the optimal extraction time, and it is difficult to obtain a coffee beverage utilizing the taste unique to each variety.

[0008]

An object of the present invention is to provide a method for producing a coffee beverage which can solve the above-mentioned inconveniences and can easily obtain a blended coffee beverage by utilizing a taste unique to each variety. With the goal.

[0009]

In order to produce the bitterness and aroma peculiar to a certain variety of coffee beans, the appropriate roasting degree differs for each variety as described above. Even if roasting to the appropriate degree of roasting, the extraction time could not be changed for each degree of roasting because the extraction was performed in a single extraction tank by mixing each type of coffee powder .

Therefore, in order to achieve the above object, the method for producing a coffee beverage of the present invention provides a powder for extraction by blending coffee bean powders of different varieties or roasting degrees singly or in a plurality of types. Each powder is stored in a different extraction tank, and each extraction tank is extracted with hot water for a predetermined time,
Obtaining a different coffee extract for each extraction powder;
Mixing a coffee extract obtained for each extraction powder to prepare a coffee beverage.

According to the production method of the present invention, coffee beans are roasted at a predetermined roasting degree for each variety and then pulverized into a powder. A plurality of kinds of powders are blended into an extraction powder, and each extraction powder is extracted in a different extraction tank. Therefore, an appropriate roasting degree can be selected for each variety, and an appropriate extraction time can be set according to the roasting degree, and a coffee extract having bitterness and aroma specific to the variety and roasting degree can be set. Can be obtained.

Therefore, a coffee beverage is prepared by mixing extracts having unique bitterness and aroma obtained from different extraction tanks for each of the above-mentioned powders for extraction, thereby making use of the unique taste of each coffee bean. Blended coffee beverages can be easily manufactured.

In the manufacturing method of the present invention, a predetermined amount of the coffee extract is set in advance by the predetermined extraction time, and the total amount of the coffee extract obtained for each extraction powder is mixed. Alternatively, a coffee beverage having a desired taste can be prepared by mixing the coffee extract at an arbitrary ratio.

[0014] In the production method of the present invention, in the step of preparing the coffee beverage, together with the coffee extract,
A milk-containing coffee beverage may be produced by mixing a milk component and an emulsion stabilizer to prepare a coffee beverage.
