Abstract

The application relates to a starch comprising greater than 70% by weight of total dietary fiber as determined by the AOAC 991.43 test method and wherein the starch has not been chemically modified.

First claim

What is claimed is:

1. A starch comprising greater than 70% by weight of total dietary fiber as determined by the AOAC 991.43 test method and wherein the starch has not been chemically modified and is granular.

2. The starch of claim 1 , wherein the amount of total dietary fiber is between about 70% to about 80% by weight.

3. The starch of claim 2 , wherein the amount of total dietary fiber is between about 72% to about 78% by weight.

4. The starch of claim 3 , wherein the amount of total dietary fiber is between about 74% to about 76% by weight.

5. The starch of claim 4 , wherein the amount of total dietary fiber is between about 72% to about 74% by weight.

6. The starch of claim 5 , wherein the amount of total dietary fiber is between about 76% to about 78% by weight.

7. The starch of claim 1 , wherein the starch is a grain starch.

8. The starch of claim 7 , wherein the grain starch is a corn starch.

9. A process comprising:
a) steeping high amylose corn kernels at a temperature from about 71° C. to about 93° C. for a time from about 24 hours to about 72 hours;
b) subjecting the high-temperature steep corn kernels to conventional wet milling;
c) subjecting the recovered intermediate starch to heat-moisture treatment; and
d) wherein the final starch comprises greater than 70% by weight of total dietary fiber as determined by the AOAC 991.43 test method and wherein the starch has not been chemically modified and is granular.

10. The process of claim 9 , wherein the steeping process is done in two stages.

11. The process of claim 10 , wherein two stage steeping process is done first at a temperature from about 71° C. to about 76° C. for a time from about 14 hours to about 26 hours and done secondly at a temperature from about 76° C. to about 88° C. for a time from about 14 hours to about 26 hours.

12. The process of claim 9 , wherein the steeping process is done in one stage.

13. The process of claim 12 , wherein the one stage steeping process is done at a temperature from about 71° C. to about 76° C. for a time from about 24 hours to about 36 hours.
