Method of improving the properties of a flour dough, a flour dough improving composition and improved food products
View Patent ↗A method of improving the rheological properties of a flour dough and the quality of the finished product made from such a dough, comprising adding an effective amount of an oxidoreductase capable of oxidizing maltose, in particular a hexose oxidase, e.g. isolated from an algal species such as Iridophycus flaccidum, Chondrus crispus or Euthora cristata and a dough improving composition comprising the oxidoreductase.
1. A dough improving composition comprising an oxidoreductase which is at least capable of oxidizing maltose, flour and at least one further dough ingredient or dough additive wherein said oxidoreductase is in an amount which results in the presence in a finished dough of 1 to 10,000 units per kg of flour.
2. A composition according to claim 1 wherein the oxidoreductase is derived from a source selected from an algal species, a plant species and a microbial species.
3. A composition according to claim 2 wherein the oxidoreductase is hexose oxidase.
4. A composition according to claim 3 wherein the hexose oxidase is derived from Chondrus crispus .
5. A composition according to claim 1 which is a pre-mixture useful for preparing a baked product or in making a noodle product or an alimentary paste product.
6. A composition according to claim 1 which comprises an additive selected from the group consisting of an emulsifying agent and a hydrocolloid.
7. A composition according to claim 6 wherein the hydrocolloid is selected from the group consisting of an alginate, a carrageenan, a pectin and a vegetable gum.
8. A dough comprising a dough improving composition comprising an oxidoreductase which is at least capable of oxidizing maltose and at least one further dough ingredient or dough additive, and flour, wherein said oxidoreductase is in an amount which results in the presence in the finished dough of 1 to 10,000 units per kg of flour.
9. A flour dough comprising an oxidoreductase which is at least capable of oxidizing maltose and flour, wherein said oxidoreductase is in an amount which results in the presence in the finished dough of 1 to 10,000 units per kg of flour.
10. The flour dough according to claim 9 wherein said flour is selected from the group consisting of wheat flour, rice flour, maize flour, barley flour, rye flour, durra flour and mixtures thereof.
11. The flour dough according to claim 9 wherein said flour dough comprises at least one further enzyme.
12. The flour dough according to claim 9 wherein said flour dough comprises at least one further enzyme and wherein said further enzyme is selected from the group consisting of cellulase, a hemicellulase, a xylanase, a starch degrading enzyme, a glucose oxidase, a lipase and a protease.
13. The flour dough according to claim 9 wherein said oxidoreductase is hexose oxidase.
14. The flour dough according to claim 9 wherein said oxidoreductase is hexose oxidase and wherein said hexose oxidase is derived from a source selected from the group consisting of an algal species, a plant species and a microbial species.
15. The flour dough according to claim 9 wherein said oxidoreductase is hexose oxidase and wherein said hexose oxidase is derived from Chondrus crispus .
16. A baked or dried product produced from a flour dough wherein said flour dough comprises an oxidoreductase which is at least capable of oxidizing maltose, wherein said oxidoreductase is in an amount which results in the presence in the finished dough of 1 to 10,000 units per kg of flour.
17. The baked or dried product according to claim 16 wherein said flour is selected from the group consisting of wheat flour, rice flour, maize flour, barley flour, rye flour, durra flour and mixtures thereof.
18. The baked or dried product according to claim 16 wherein said flour dough comprises at least one further enzyme.
19. The baked or dried product according to claim 16 wherein said flour dough comprises at least one further enzyme and wherein said further enzyme is selected from the group consisting of cellulase, a hemicellulase, a xylanase, a starch degrading enzyme, a glucose oxidase, a lipase and a protease.
20. The baked or dried product according to claim 16 wherein said oxidoreductase is hexose oxidase.
21. The baked or dried product according to claim 16 wherein said oxidoreductase is hexose oxidase and wherein said hexose oxidase is derived from a source selected from the group consisting of an algal species, a plant species and a microbial species.
22. The baked or dried product according to claim 16 wherein said oxidoreductase is hexose oxidase and wherein said hexose oxidase is derived from Chondrus crispus .
23. The baked product according to claim 16 wherein said baked product is a bread product.
