Abstract

The present invention provides a process for producing a food ingredient or beverage ingredient. The present invention also provides a process for producing food product or beverage product. The present invention also provides a process for providing starch, amylose, amylopectin, β-glucan, fructan, non-starch polysaccharide, dietary fiber or resistant starch to improve one or more indicators of health in a mammal.

First claim

The invention claimed is:

1. Barley grain comprising:
a) a starch content of which at least 40% (w/w) is amylose,
b) a null mutation of a gene encoding starch synthase IIa (SSIIa), wherein the barley grain is homozygous for the null mutation,
c) a level or activity of a starch synthase IIIa (SSIIIa) protein which is less than 25% of the level or activity relative to that of the SSIIIa protein in barley grain of variety Himalaya, and
d) a starch content of 41-65% (w/w).

2. The barley grain of claim 1 , wherein the starch content of the barley grain comprises 50% (w/w) amylose.

3. The barley grain of claim 1 , wherein the starch content of the barley grain comprises 60% (w/w) amylose.

4. The barley grain of claim 1 , wherein the starch content of the barley grain is at least 43% by weight of the barley grain.

5. The barley grain of claim 1 , wherein a β-glucan content of 5-9% (w/w) is present in the barley grain.

6. The barley grain of claim 1 , wherein a β-glucan content of greater than 9% (w/w) is present in the barley grain.

7. The barley grain of claim 1 , wherein a fructan content of 2-11% (w/w) is present in the barley grain.

8. The barley grain of claim 7 , wherein the fructan content has a degree of polymerization from 3 to 12.

9. A barley plant that produces or is capable of producing the barley grain of claim 1 .

10. A barley plant that produces or is capable of producing the barley grain of claim 2 .

11. A barley plant that produces or is capable of producing the barley grain of claim 3 .

12. A barley plant that produces or is capable of producing the barley grain of claim 4 .

13. A barley plant that produces or is capable of producing the barley grain of claim 5 .

14. A barley plant that produces or is capable of producing the barley grain of claim 6 .

15. A barley plant that produces or is capable of producing the barley grain of claim 7 .

16. A barley plant that produces or is capable of producing the barley grain of claim 8 .
