## Abstract

The present invention provides a new green tea beverage packed in a container that has a good balance of taste and odor, and has refreshing aftertaste with nutritious taste, and has odor note and nutritious taste even in a cold state. The green tea beverage packed in a container of the present invention has a sugar concentration, which is the sum of a reducing sugar concentration and a non-reducing sugar concentration, being 75 ppm to 250 ppm, a ratio of the non-reducing sugar concentration relatively to the reducing sugar concentration (non-reducing sugar/reducing sugar) being 2.0 to 8.0, and a particle size of the cumulative 90% by mass (D90) being 2500 μm or more.

## Claims

### Claim 1

A green tea beverage packed in a container of which a sugar concentration, which is the sum of a reducing sugar concentration and a non-reducing sugar concentration, is 75 ppm to 250 ppm, a ratio of the non-reducing sugar concentration relatively to the reducing sugar concentration (non-reducing sugar/reducing sugar) is 2.0 to 8.0, and a particle size of the cumulative 90% by mass (D90) is 2500 μm or more.

### Claim 2 (depends on 1)

The green tea beverage packed in a container according to claim 1, wherein a content ratio of furfural relatively to geraniol (furfural/geraniol) is 0.5 to 3.0.

### Claim 3 (depends on 1)

The green tea beverage packed in a container according to claim 1, wherein a ratio of sugars to a soluble solid content derived from tea leaves (sugars/(soluble solid content derived from the tea leaves×100)) is 2.5 to 5.0.

### Claim 4 (depends on 1)

The green tea beverage packed in a container according to claim 1, wherein a ratio of a concentration of electron-localized catechin relatively to the soluble solid content derived from tea leaves (electron-localized catechin/(soluble solid content derived from the tea leaves×100)) is 15.0 to 20.0.

### Claim 5

A method of manufacturing a green tea beverage packed in a container, comprising:
adjusting a sugar concentration in a green tea beverage, which is the sum of a reducing sugar concentration and a non-reducing sugar concentration, to 75 ppm to 250 ppm;
adjusting a ratio of the non-reducing sugar concentration relatively to the reducing sugar concentration (non-reducing sugar/reducing sugar) to 2.0 to 8.0; and
adjusting a particle size of the cumulative 90% by mass (D90) to 2500 μm or more.

### Claim 6 (depends on 5)

The method of manufacturing a green tea beverage packed in a container according to claim 5, wherein the particle size of the cumulative 90% by mass (D90) is adjusted by filtration.

### Claim 7 (depends on 6)

The method of manufacturing a green tea beverage packed in a container according to claim 6, wherein the particle size of the cumulative 90% by mass (D90) is adjusted by filter cake filtration using either one or both of a filter media containing silica content and a porous media.

### Claim 8

A method of improving flavor of a green tea beverage packed in a container, comprising:
adjusting a sugar concentration in a green tea beverage, which is the sum of a reducing sugar concentration and a non-reducing sugar concentration, to 75 ppm to 250 ppm;
adjusting a ratio of the non-reducing sugar concentration relatively to the reducing sugar concentration (non-reducing sugar/reducing sugar) to 2.0 to 8.0; and
adjusting a particle size of the cumulative 90% by mass (D90) to 2500 μm or more.
