Problems solved by technology

Drip extraction is generally used in the production of industrial coffee beverages. Compared with household drip extraction, coffee beans are in contact with heated water for a long time, and there is a problem that low-boiling compounds, which are important aroma components, After volatilization or oxidation, the taste and aroma of the resulting coffee beverage deteriorate
[0004] On the other hand, in order to enhance the mellow taste, it is necessary to increase the coffee concentration, but when the coffee concentration is high, coffee deposits will be generated during storage, and there is a tendency for storage stability to decrease.

Embodiment 1

[0060] 1-1. Preparation of coffee extract, dried coffee extract and coffee extract

[0061] As the coffee extract, a coffee extract prepared by using a pulverizer (manufactured by Granulator Co., Ltd., Japan) to pulverize medium-roasted Brazilian coffee beans so that the particles with a particle diameter of 710 μm or more accounted for 80% or more, Warm water at 55° C. was dropped to prepare an extract of Brix 2.4, which was then filtered through a 500-mesh screen to remove insoluble solids to obtain a coffee extract.

[0062]As dry coffee extracts, three types of instant coffee were used (instant coffee 1 and instant coffee 2: coffee beans produced in Brazil were used. Extracted by continuous multi-tube extraction, concentrated, and spray-dried. Instant coffee 3: coffee beans produced in Brazil were used Coffee beans. Concentrated after extraction by continuous multi-tube extraction method, and obtained by freeze-drying), they are dissolved with 20 times the amount of hot ...

[0079] 2-1. Preparation of coffee extract and dried coffee extract

[0080] As the coffee extract, the coffee extract obtained by grinding the mixed coffee beans with a grinder (manufactured by Granulator Co., Ltd. in Japan) so that the particles with a particle diameter of 710 μm or more were 80% or more was used. It was dripped to prepare a Brix 2.0 extract, which was then filtered through a 500-mesh screen to remove insoluble solids to obtain a coffee extract.

[0081] As the dry coffee extract, instant coffee whose absorbance at a wavelength of 680 nm per 1% by weight of soluble solids when diluted in water is 0.29 (Brazilian-grown coffee beans were used. Extracted by a continuous multi-tube extraction method, concentrated, and spray-dried and get). Regarding the absorbance of the dried coffee extract, in the same manner as in Example 1, the instant coffee was diluted with water to about 30 times, filtered through a 500-mesh mesh to remove insoluble components, and then...

Abstract

A container-packed coffee beverage which exhibits the original coffee flavor while ensuring a high storage stability is produced by mixing a liquid coffee extract obtained by extracting with hot water at 30 to 65oC with a dry coffee extract, which shows an absorbance of 0.8 or less at a wavelength of 680 nm per percent by weight of soluble solid matters when dissolved in water, and packing in a container. This procedure is preferably applicable to a sugar-free coffee (black coffee) beverage. Also, it is preferably applicable to a hot beverage.

Description

Technical field [0001] The present invention relates to a container-packed coffee beverage excellent in flavor and storage stability and a method for producing the same. Background technique [0002] Coffee beverages are beverages that value qualities such as flavor, especially taste and aroma. Drip extraction is usually used in the manufacture of industrial coffee drinks. Compared with drip extraction at home, etc., the coffee beans are in contact with heated water for a long time, and there are the following problems: low-boiling point compounds, which are important aroma components, are not immediately extracted after extraction. After evaporation or oxidation, the taste and aroma of the resulting coffee beverage become worse. For this reason, various proposals have been made to achieve the taste of freshly brewed coffee at home or the like by using a container-packed beverage filled in a can or the like. [0003] For example, there is the following method: through a tw...
