## Abstract

A process for modifying starches comprises atomising an aqueous slurry of a non-pregelatmised, granular, high amylose starch into an internal chamber in a bi-fluid nozzle of a dryer and treating the atomized slurry, in the internal chamber, with medium pressure steam to produce a slurry of partially treated starch granules followed by discharging the slurry into a reactor where it is contacted with superheated steam to produce dry, particulate, cold water-swelling, intact, high amylose starch granules. The cold water-swelling, intact, high amylose starch granules have greater than 15% solubles. At a starch concentration of 1%, in UDMSO (9 volumes DMSO and 1 volume 6M urea) at 25° C., the ratio of apparent viscosity of said cold water-swelling, intact, high amylose starch granules to the apparent viscosity of the parent non-pregelatinised, granular, high amylose starch is lower than 1.00. The cold water-swelling, high amylose granular starch of the invention is useful in the manufacture of food products, especially confectionery products and convenience food products.

## Claims

### Claim at position 1

-6. (canceled)

### Claim 7

Cold water-swelling, high amylose starch granules, said starch retaining its granular integrity, said starch having greater than 15% solubles and having in UDMSO (9 volumes DMSO and 1 volume 6M urea) at 1% starch concentration at 25° C. a ratio of apparent viscosity of said cold water-swelling, intact, high amylose starch granules to the apparent viscosity of the parent non-pregelatinised, granular, high amylose starch of lower than 1.00, wherein said starch has an amylose content greater than 35% by weight.

### Claim 8 (depends on 7)

Cold water-swelling starch granules according to claim 7, which have greater than 16% solubles.

### Claim 9 (depends on 7)

Cold water-swelling starch granules according to claim 7, having a total amylose content of at least 40% by weight.

### Claim 10 (depends on 9)

Cold water-swelling starch granules according to claim 9, having a total amylose content of at least 45% by weight.

### Claim 11

(canceled)
