Abstract

Provided is a caffeine-reduced green tea beverage packed in a container which can be enjoyed either hot or cold, and which has a sense of being concentrated due to its roasted aroma, and which has an astringent richness, while at the same time being refreshing. The green tea beverage packed in a container has a caffeine concentration of less than 90 ppm, and a total sugar concentration (obtained by adding the concentration of nonreducing sugars and the concentration of reducing sugars) that falls within the range of 100 ppm to 300 ppm; a ratio of the concentration of nonreducing sugars to the concentration of reducing sugars (non-reducing sugars/reducing sugars) that falls within the range of 13.0 to 23.0, and a ratio of ester catechins to sugar concentration (ester catechins/sugars) that falls within the range of 0.4 to 1.1.

Claims

1. A green tea beverage packed in a container wherein,

a concentration of caffeine is less than 90 ppm;

a concentration of sugars, a sum of the concentration of non-reducing sugars and the concentration of reducing sugars is 100 ppm to 300 ppm;

a ratio of the concentration of non-reducing sugars relative to the concentration of reducing sugars (non-reducing sugars/reducing sugars) is 13.0 to 23.0; and

,

a ratio of the concentration of ester type catechins relative to the concentration of sugars (ester type catechins/sugars) is 0.4 to 1.1.

2. A method of preparing a green tea beverage packed in a container, comprising;

adjusting a concentration of caffeine in a green tea beverage to less than 90 ppm;

adjusting a concentration of sugars, a sum of a concentration of non-reducing sugars and a concentration of reducing sugars to 100 ppm to 300 ppm;

adjusting a ratio of the concentration of non-reducing sugars relative to a concentration of reducing sugars (non-reducing sugars/reducing sugars) to 13.0 to 23.0; and

,

adjusting a ratio of the concentration of ester type catechins relative to a concentration of sugars (ester type catechins/sugars) to 0.4 to 1.1.

2-1. A method of improving a flavor of a green tea beverage packed in a container, comprising;

adjusting a concentration of caffeine in a green tea beverage to less than 90 ppm;

adjusting a concentration of sugars, a sum of a concentration of non-reducing sugars and a concentration of reducing sugars to 100 ppm to 300 ppm;

adjusting a ratio of a concentration of non-reducing sugars relative to a concentration of reducing sugars (non-reducing sugars/reducing sugars) to 13.0 to 23.0; and

,

adjusting a ratio of a concentration of ester type catechins relative to a concentration of sugars (ester type catechins/sugars) to 0.4 to 1.1.
