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 was used. 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 amoun...
Embodiment 2
[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...
