  • Publication number: 20110091599
    Abstract: The present invention relates to a method for preparing dough. Particularly the invention relates to a method for producing dough that can be processed via sheeting (i.e. a sheetable dough). Even more particular, the invention relates to a method for manufacturing sheetable dough with a water addition level which level would normally result in a dough which can not be processed because it is too sticky. The present invention provides a method for preparing sheetable dough comprising adding an amount of water and an effective amount of oxidase to flour and wherein said amount of water in the absence of said oxidase results in a dough that can not be processed due to its stickiness.

  • Publication number: 20100074991
    Abstract: The invention relates to newly identified polynucleotide sequences comprising a gene that encodes a novel oxidoreductase isolated from Aspergillus niger. The invention features the full length nucleotide sequence of the novel gene, the cDNA sequence comprising the full length coding sequence of the novel oxidoreductase as well as the amino acid sequence of the full-length functional protein and functional equivalents thereof. The invention also relates to methods of using these enzymes in baking and in dairy applications. Also included in the invention are cells transformed with a polynucleotide according to the invention and cells wherein a oxidoreductase according to the invention is genetically modified to enhance or reduce its activity and/or level of expression.
