Denatured Zein Protein Binding in Wet Pet Food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pet food products, particularly wet pet foods, face challenges in replacing meat proteins with sustainable alternatives that maintain nutritional quality, texture, and palatability while avoiding increased environmental impact and equipment issues like stickiness and fines formation during processing.
Innovation Solution
The process involves denaturing zein protein through mechanical and thermal energy treatment to create a sterilization-stable binding agent that forms a homogeneous matrix with animal proteins, allowing for the production of reconstituted meat chunks with improved strength and texture, suitable for use in wet pet foods without requiring significant changes to existing processing equipment or recipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If meat protein is replaced with alternative proteins to reduce environmental impact, then sustainability is improved, but product quality and nutritional value deteriorate
Solution Approach 1:
The patent combines zein protein (from corn) with animal by-products to create a composite protein material that maintains the functional properties of meat while using sustainable ingredients. This composite approach allows replacement of meat protein with alternative proteins without sacrificing product quality or nutritional value.
Solution Approach 2:
The patent modifies the physical and chemical parameters of zein protein through processing conditions (temperature, pH, moisture content) to enhance its binding ability and functional properties. By changing these parameters, the alternative protein achieves meat-like texture and quality, resolving the contradiction between sustainability and product quality.
2Object-affected harmful factors
If alternative proteins are used in pet foods, then environmental impact is reduced, but texture and palatability deteriorate
Solution Approach 1:
The patent optimizes processing parameters including temperature (60-80°C), pH (5.5-7.5), and moisture content (15-30%) to transform zein protein into a form that provides desirable texture and mouthfeel. These parameter changes enable the alternative protein to achieve meat-like texture that is palatable to pets.
Solution Approach 2:
The patent creates specific functional zones within the protein matrix by controlling local composition and structure during processing. This local quality control ensures that critical texture-providing regions maintain meat-like properties while the overall formulation uses sustainable alternative proteins.
3Ease of manufacture
If new analogue products are prepared using existing processing assets, then manufacturing cost is reduced, but processing capability and product performance deteriorate
Solution Approach 1:
The patent formulates the alternative protein product to work with existing processing equipment and methodologies used for meat products. The zein-based analogue can be processed through standard extrusion, cooking, and forming equipment, making it universally compatible with current manufacturing assets while maintaining product performance.
Solution Approach 2:
The patent replicates the processing workflow and product structure of traditional meat-based pet foods using alternative proteins. By copying the established process sequence and final product architecture, the analogue can be manufactured using existing assets without requiring new equipment or significantly modified processes.
4Strength
If heat-setting binders are added to restructured meat chunks, then chunk strength is improved, but product complexity and processing steps increase
Solution Approach 1:
The patent concentrates binding functionality within the zein protein matrix itself rather than adding separate binders. The zein protein is processed to create local binding zones that provide chunk strength without requiring additional processing steps or separate binder addition, thereby maintaining simple processing while achieving adequate strength.
