CMC-Enzyme Dough for Uniform Oven Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-laminated bread products often suffer from poor oven spring and irregular break opening, leading to unsatisfactory texture and appearance during baking.
Innovation Solution
Incorporating carboxymethyl cellulose (CMC) in the dough at 0.1-2% by weight of flour, combined with cellulase or lipase, providing 100-600 units of cellulase activity or 20-110 units of lipase activity per kg of flour, to enhance oven spring and break opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional bread dough is used without additives, then the formulation is simple, but the oven spring is poor and break opening is irregular
Solution Approach 1:
The patent combines carboxymethyl cellulose (CMC) with specific enzymes (cellulase and/or lipase) to create a composite dough formulation. This composite approach allows the dough to exhibit both improved oven spring uniformity and controlled break opening while maintaining a relatively simple ingredient list consisting of flour, water, yeast, CMC, and the specified enzymes.
Solution Approach 2:
The patent optimizes specific parameters including CMC concentration (0.1-2% of flour weight), enzyme activity units (100-600 CU/kg flour for cellulase, 20-110 LU/kg flour for lipase), and pH range (4.0-6.0) to achieve the desired oven spring and break opening characteristics. These parameter optimizations resolve the contradiction by providing precise control over dough behavior.
2Stability of the object's composition
If CMC is added to improve viscosity and stability, then emulsion stabilization is improved, but dough expansion and break opening may be restricted
Solution Approach 1:
The patent introduces enzymes (cellulase and/or lipase) as intermediary substances that mediate between CMC's stabilizing effect and the dough's expansion requirement. These enzymes modify the CMC-dough matrix to allow controlled gas bubble formation and coalescence, enabling both emulsion stability and adequate dough expansion to coexist.
Solution Approach 2:
The patent specifies optimal CMC concentrations (0.1-2% of flour weight) and pH ranges (4.0-6.0) to balance emulsion stabilization with dough expandability. By controlling these parameters, the formulation achieves both improved emulsion stability and acceptable dough volume increase during baking.
3Manufacturing precision
If enzyme activity is increased to improve break opening, then cut surface opening is enhanced, but dough structure may become too weak
Solution Approach 1:
The patent precisely controls enzyme activity levels (100-600 CU/kg flour for cellulase, 20-110 LU/kg flour for lipase) and operates within a specific pH range (4.0-6.0) to optimize break opening while maintaining adequate dough structure strength. This parameter control prevents excessive enzyme activity from weakening the dough too much.
Solution Approach 2:
The patent applies partial enzyme action by using moderate enzyme concentrations that provide sufficient break opening improvement without completely degrading the dough structure. The enzyme activity is calibrated to achieve the desired effect while leaving residual structural integrity in the baked product.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method results in uniform dough expansion and predictable break opening, preventing sagging and ensuring appealing, reproducible baked products with improved texture and appearance.
Implementation Method 1
CMC is a cellulose derivative with carboxymethyl groups bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. CMC is used in foods as a viscosity modifier or thickener
Implementation Method 2
cellulase in an amount equivalent to 100-600 units of cellulase activity (CU) per kg of flour
Implementation Method 3
lipase in an amount equivalent to 20-110 units of lipase activity (LU) per kg of flour

AI summary
The invention relates to a flour-based non-laminated bread dough containing flour and 40-90% water by weight of flour, said dough further containing 0.1-2% CMC by weight of flour; and 100-600 units of cellulase activity (CU) per kg of flour and/or 20-110 units of lipase activity (LU) per kg of flour. The bread dough of the present invention exhibits excellent oven spring. In addition, crusty bread products that have been prepared in accordance to the present invention show improved "break opening", meaning that cuts into the surface of the dough open up in an appealing manner during baking. The invention also provides a bread improver product comprising CMC; at least one enzyme selected from cellulose and lipase; and a carrier material. Finally, the invention concerns the use of the aforementioned bread improver product for improving the appearance of cut bread, embossed bread, sheeted and folded bread or braided bread.
