Abstract
This invention relates to coffee beans from which the silverskin located in the center of the coffee bean has been separated and removed, and to a method for producing the same, which allows for the preservation of the coffee's characteristic flavor, aroma, and color. Furthermore, by suppressing rancidity and maintaining the original freshness of the coffee beans, the shelf life can be extended. Additionally, by removing the silverskin located in the center of the coffee bean, the amount of coffee extracted can be increased, and the raw material cost of the coffee beans can be reduced. Moreover, by removing factors that cause deterioration of coffee's flavor, such as fibrous material and coffee oil, the coffee's characteristic flavor, aroma, and color can be preserved.
