“Rainbow roll 2.0” showcase for cultivated seafood
Given the nascent market for cultivated meats, especially for cultivated seafood, a “Rainbow Roll 2.0” product could be an attractive market-entry commercial product.
Bioprocess design
Developing open-access model production facility blueprints
Open-access blueprints would provide a head start on facility design and allow equipment manufacturers and engineering companies to address standard industry needs.
Computational models of perfusion flow through scaffolds
For tissue-structured cultivated meat production, the transition from the proliferation phase to differentiation phase may involve seeding cells onto a prefabricated scaffold within a perfusion bioreactor. Medium is then perfused through the cell-laden scaffold, providing nutrients and oxygen as cells differentiate and mature. Computational models are needed to describe fluid flow through scaffolds to better understand mass transfer and shear forces. These models will inform considerations for scaffold materials, geometries, dimensions, fabrication methods, and bioprocess design as well as considerations for the composition and viscosity of the medium.
Expand capacity for demonstration-scale and mid-scale co-manufacturing
Companies entering the alt protein space often struggle to secure line time at demonstration-scale and mid-scale commercial production facilities. Greater availability of mid-scale contract capacity would reduce capital outlays and facilitate scaling, allowing alt protein companies to maintain greater control over their equity and exercise more influence within the supply chain. Contracting production allows for a more modular supply chain, with participants achieving gains from specialization, allowing for better financial and organizational structuring around core competencies.
Database of facility engineering, design, and construction firms
Dedicated brokers, consultants, directories, and other matching mechanisms could help connect alternative protein companies to engineering/design/construction firms with relevant experience and interest in the alternative protein sector.
Post-harvest processes and end product characterization for cultivated meat
A number of cellular processes occurring after slaughter are known to affect the quality and sensory properties of conventional meat. Cultivated meat will offer unprecedented control over these parameters and therefore over the quality of the final product, but it is critical to understand exactly how post-harvest processes for cultivated meat can or should differ from post-slaughter processes in conventional meat. This research can enable subsequent innovations in bioprocess design, media formulation, cell line development, or harvesting techniques to confer consistently high levels of meat quality from cultivated meat processes.
Cultivated meat co-product valorization
Animal cell metabolism within cultivators can produce useful co-product side streams that provide monetary value to the manufacturer while creating a novel source of inputs for other industries. Potential side streams should be identified and analyzed for their utility and economic viability, in addition to developing methods for efficient side stream capture.
Suppressing hyper-branching of filamentous fungi
Prolonging continuous cultivation of filamentous fungi by suppressing hyper-branching to improve texture and boost production efficiency.
3D microenvironments for cell expansion
Proliferation and high-density cell growth are fundamentally important to scaling cultivated meat production. Recent demonstrations of stem cell expansion in 3D microenvironments such as encapsulated spheres or tubules can generate cell densities far higher than industry-leading stirred tank bioreactors with minimal loss of cell viability or stemness. As a scalable platform, the use of 3D microenvironments for stem cell expansion and differentiation—particularly with the relevant cell types used in cultivated meat—warrants further investigation.
