Claims
- 1. A method for causing gelling or increase of viscosity of an aqueous medium containing a gellable polymeric material having substituents with phenolic hydroxy groups, the method comprising adding to said aqueous medium an amount of a laccase effective for increasing said viscosity.
- 2. The method of claim 1, wherein said gellable polymeric material is a polysaccharide having substituents with phenolic hydroxy groups.
- 3. The method of claim 1, wherein the phenolic substituents are cinnamic acid ester groups.
- 4. The method of claim 2, wherein the polysaccharide is an arabinoxylan or a material comprising pectin.
- 5. The method of claim 4, wherein the arabinoxylan is obtainable from a cereal.
- 6. The method of claim 5, wherein the cereal is wheat or maize.
- 7. The method of claim 4, wherein the arabinoxylan is extracted from flour or bran.
- 8. The method of claim 4, wherein the pectic material is from a member of the family Chenopodiaceae.
- 9. The method of claim 8, wherein the pectic material is from sugar beets.
- 10. The method of claim 9, wherein the pectic material is extracted from sugar beet pulp.
- 11. The method of claim 1, wherein the gellable polymeric material cones two or more polysaccharides having phenolic substituents.
- 12. The method of claim 11, wherein the phenolic substituents are cinnamic acid ester groups.
- 13. The method of claim 11, wherein the gellable polymeric material comprises an arabinoxylan and a material comprising pectin.
- 14. The method of claim 13, wherein the arabinoxylan is a cereal arabinoxylan and the pectic material is beet pectin.
- 15. The method of claim 14, wherein the cereal arabinoxylan is wheat or maize.
- 16. The method of claim 1, wherein the laccase is derived from a microorganism.
- 17. The method of claim 16, wherein the microorganism is a fungus.
- 18. The method of claim 17, wherein the laccase is derived from a member of the genus Trametes or the genus Myceliophthora.
- 19. The method of claim 18, wherein the laccase is derived from Trametes villosa or from Myceliophthora thermophila.
- 20. The method of claim 1, wherein the amount of laccase employed is in the range from 0.01 to 100 kLACU per kg of gellable polymeric material.
- 21. The method of claim 13, wherein the gelled product is subjected to a drying or dehydration procedure.
