## Abstract

The present invention provides a green tea beverage packed in a container that has strong fire odor (savory flavor) and flavor sustention, and has less coarse taste, has transparency, and allows delicious drinking even in a cold state. The green tea beverage packed in a container of the present invention has a sugar concentration, which is a sum of the reducing sugar concentration and a non-reducing sugar concentration, being 50 ppm to 250 ppm, a ratio of the non-reducing sugar concentration to the reducing sugar concentration (non-reducing sugar/reducing sugar) being 8 to 24, and a particle size of cumulative 90% by mass of particles (D90) being 3500 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 50 ppm to 250 ppm, a ratio of the non-reducing sugar concentration to the reducing sugar concentration (non-reducing sugar/reducing sugar) is 8 to 24, and a particle size of cumulative 90% by mass of particles (D90) is 3500 μm or more.

### Claim 2 (depends on 1)

The green tea beverage packed in a container according to claim 1, wherein the ratio of an electron-localized catechin concentration to a sugar concentration (electron-localized catechin/sugars) is 1.8 to 5.0.

### Claim 3

A method of manufacturing a green tea beverage packed in a container comprising steps of;
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 50 ppm to 250 ppm;
adjusting a ratio of the non-reducing sugar concentration to the reducing sugar concentration (non-reducing sugar/reducing sugar) to 8 to 24; and
adjusting a particle size of cumulative 90% by mass of particles (D90) to 3500 μm or more.

### Claim 4 (depends on 3)

The method of manufacturing a green tea beverage packed in a container according to claim 3 comprising steps of:
adjusting the particle size of the cumulative 90% by mass (D90) of particles by filtration.

### Claim 5 (depends on 4)

The method of manufacturing a green tea beverage packed in a container according to claim 4 comprising steps of:
adjusting the particle size of the cumulative 90% by mass of particles (D90) by filter cake filtration using either one or both of a filter media containing silica content and a porous media.

### Claim 6

A method for improving flavor of a green tea beverage packed in a container comprising steps of:
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 50 ppm to 250 ppm;
adjusting a ratio of the non-reducing sugar concentration to the reducing sugar concentration (non-reducing sugar/reducing sugar) to 8 to 24; and
adjusting a particle size of cumulative 90% by mass of particles (D90) to 3500 μm or more.
