## Abstract

The use of a granulated xanthan gum comprising, relative to 100% by mass of the granulated xanthan gum: xanthan gum granules having a degree of hardness of 2 N or higher and lower than 8 N in an amount of 5% by mass or higher; and xanthan gum granules having a degree of hardness of 8 N or higher in an amount of 20% by mass or lower makes it possible to provide a granulated xanthan gum and a thickening composition comprising the granulated xanthan gum which undergo suppressed formation of unmixed lumps in a wide variety of water-containing foods such as water, teas, refreshing beverages, dairy beverages, soups, and thick liquid foods, even when the xanthan gum concentration is 50% by mass or higher.

## Claims

### Claim at position 1

1: A granulated xanthan gum for thickening composition, comprising, relative to 100% by mass of the granulated xanthan gum:
xanthan gum granules having a degree of hardness of 2 N or higher and lower than 8 N in an amount of 5% by mass or higher; and
xanthan gum granules having a degree of hardness of 8 N or higher in an amount of 20% by mass or lower.

### Claim at position 2 (depends on 1)

2: A thickening composition comprising the granulated xanthan gum according to claim 1.

### Claim at position 3 (depends on 2)

3: The thickening composition according to claim 2, further comprising a water-soluble dispersant.

### Claim at position 4 (depends on 3)

4: The thickening composition according to claim 3, wherein
a mass ratio of the xanthan gum:the water-soluble dispersant in the thickening composition is 45:55 to 98:2.

### Claim at position 5 (depends on 3)

5: The thickening composition according to claim 3, wherein
the water-soluble dispersant is a metal salt-enclosing dextrin.

### Claim at position 6 (depends on 3)

6: The thickening composition according to claim 3, which is obtained by granulating the granulated xanthan gum and the water-soluble dispersant.

### Claim at position 7 (depends on 2)

7: The thickening composition according to claim 2, which is used for a swallowing aid.

### Claim at position 8 (depends on 2)

8: A food comprising the thickening composition according to claim 2.

### Claim at position 9

9: A method for producing a thickening composition, comprising the step of mixing or granulating a granulated xanthan gum and a water-soluble dispersant, the granulated xanthan gum having been prepared such that an amount of granules having a degree of hardness of 2 N or higher and lower than 8 N is 5% by mass or higher and an amount of granules having a degree of hardness of 8 N or higher is 20% by mass or lower, relative to 100% by mass of the granulated xanthan gum.
