摘要: Lipolytic enzymes which improve the properties of dough or baked products generally have a high activity towards lipids which are capable of forming a hexagonal phase, and a screening method was developed on this basis. The improved properties may include a larger loaf volume, an improved shape factor, an improved crumb structure, reduced dough stickiness, improved dough stability and/or improved tolerance towards extended proofing. The advantageous lipid-degrading enzymes have higher activity towards MGDG and/or unsaturated phosphatidyl ethanolamines (APE, PE) than towards DGDG, PC, PS, PI, PG, saturated phosphatidyl ethanolamines, ALPE and/or triglicerides.

摘要: The invention relates to a variant of a parent Termamyl-like alpha-amylase, which variant exhibits altered properties, in particular reduced capability of cleaving a substrate close to the branching point, and improved substrate specificity and/or improved specific activity relative to the parent alpha-amylase.

摘要: The inventors have developed a method of modifying the amino acid sequence of a CGTase to obtain variants. The variants may form linear oligosaccharides as an initial product by starch hydrolysis and a reduced amount of cyclodextrin and may be useful for anti-staling in baked products. The method is based on a comparison of three-dimensional (3D) structures of the CGTase with the structure of a maltogenic alpha-amylase where one or both models includes a substrate. The invention also provides novel CGTase variants.

摘要: A method of screening lipolytic enzymes is used to identify candidates for a baking additive which can improve the properties of a baked product when added to the dough. The screening method involves contacting the enzyme with N-acyl phosphatidyl ethanolamine (APE) or N-acyl lyso-phosphatidyl ethanolamine (ALPE), and detecting hydrolysis of an ester bond in the APE or ALPE.

摘要: The inventors have developed improved polypeptides by substituting or deleting specified amino acids in fungal lipolytic enzymes. More particularly, the polypeptides result in a reduction of dough stickiness when they are added to a dough. The polypeptides may particularly have activity on polar lipids.
