Abstract

The present invention relates to a method for producing a food product comprising hydrolysed starch, as well as to products obtainable by the method. The method has the advantage of reducing the amount of sugar (i.e. maltose) produced by hydrolysis as compared to conventional methods of starch hydrolysis and present the additional advantage of providing good processability for the food product.

First claim

The invention claimed is:

1. A method for producing a food product comprising hydrolysed starch, the method comprising the steps of:
a) mixing a material comprising both starch and at least one amylolytic enzyme with water to form a mixture;
b) adjusting a temperature of the mixture to a temperature lower than 55° C., and simultaneously subjecting the mixture to high shear mixing in a Ring Layer Mixer, to form a homogenized mixture; and
c) incubating the homogenized mixture such that a desired degree of hydrolysis is achieved,
thereby obtaining the food product comprising hydrolysed starch, wherein the food product comprises 0.1 wt. % to 6 wt. % maltose.

2. The method according to claim 1 , wherein in step b) the mixture of step a) is adjusted at a temperature ranging from 35 to 45° C.

3. The method according to claim 1 , wherein in step b) the mixture of step a) is adjusted to a temperature ranging from 20 to 50° C.

4. The method according to claim 1 , wherein step b) is performed by direct steam injection.

5. The method according to claim 1 , wherein the high shear mixing in step b) is such that the mixture is homogenized within a time period of 1 second to 50 seconds.

6. The method according to claim 1 , wherein the material is a plant preparation.

7. The method according to claim 1 , wherein the material is selected from the group consisting of wheat flour, rice flour, maize flour, barley flour, rye flour, oat flour, buckwheat flour, millet flour, quinoa flour, sorghum flour, a flour made from one or more tubers, a flour made from legumes and combinations thereof.

8. The method according to claim 1 , wherein the material comprises wheat flour.

9. The method according to claim 1 , wherein the at least one amylolytic enzyme comprises amylase not endogenous to the material.

10. The method according to claim 9 wherein the amylase is an alpha-amylase not endogenous to the material.

11. The method according to claim 1 , wherein the mixture has a total solids content of 20 to 60% w/w.

12. The method according to claim 1 , further comprising additional heat treatment of the homogenized mixture.

13. The method according to claim 1 wherein the food product comprises 0.1 wt. % to 5 wt. % maltose.

14. The method according to claim 1 wherein the food product comprises 0.1 wt. % to 2 wt. % maltose.

15. A food product made by the method of claim 1 .

16. The method according to claim 1 wherein the mixture consists of the starch, the at least one amylolytic enzyme and the water.

17. The method according to claim 1 wherein the mixture further comprises one or more ingredients selected from the group consisting of oils, proteins, amino acids, natural sugars, refined sugars, prebiotics, minerals, fruit ingredients, milk-based ingredients, and vitamins.
