Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Culturing seafood meat poses significant technological and financial challenges, including scale-up, cost of goods, energy consumption, replicating natural texture and structure, and maintaining flavor, with specific difficulties in producing high yields of progenitor muscle cells for cell-based food products.
Innovation Solution
A method involving the extraction and separation of progenitor muscle cells from tissue samples using enzymatic treatment and density gradient separation, followed by recapturing and replating unattached cells to enhance yield, and culturing these cells with growth stimulatory signals to produce seafood products that can include animal or non-animal derived ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cell culture methods are used for seafood meat production, then the process is simple, but the yield of progenitor muscle cells is insufficient
Solution Approach 1:
The cell culture process is divided into multiple sequential steps: initial plating, attachment period, medium collection, and replating of unattached cells. This segmentation allows systematic recovery and utilization of progenitor muscle cells that would otherwise be lost, thereby increasing overall yield while maintaining manageable process complexity through structured phases
Solution Approach 2:
The method recovers unattached progenitor muscle cells from the culture medium by collecting and replating them onto fresh surfaces. This recovery mechanism prevents cell loss and maximizes the utilization of available progenitor cells, directly addressing the yield insufficiency problem without requiring complex additional equipment
2Productivity
If cell culture is scaled up for industrial production, then food production capacity increases, but cost of goods and energy consumption increase
Solution Approach 1:
The culture medium serves dual purposes: it supports cell growth during the attachment phase and subsequently serves as the collection medium for recovering unattached cells. This self-service approach eliminates the need for separate recovery procedures and reduces overall process energy consumption while maintaining high productivity through efficient cell utilization
3Productivity
If conventional cell isolation methods are used, then the process is simple, but cell yield and quality are insufficient for high-quality food products
Solution Approach 1:
The method incorporates feedback by collecting culture medium containing unattached progenitor muscle cells and replating them onto fresh surfaces. This feedback loop ensures continuous recovery and utilization of viable cells, enhancing both yield and quality while maintaining process simplicity through a straightforward repeatable cycle
