Structuring the Future of Cultured Meat: Hybrid Gel-Based Scaffolds for Edibility and Functionality

Area of Science:

• Biomaterials Science
• Food Engineering
• Sustainable Agriculture

Background:

• Cultured meat offers a sustainable alternative to traditional agriculture.
• Scaffolds are crucial for cell attachment, growth, and tissue development in cultured meat.
• Existing reviews often focus on fabrication, lacking a food-centric material design perspective.

Purpose of the Study:

• To review the development of gel-based hybrid biomaterials for edible cultured meat scaffolds.
• To emphasize material-centric design strategies focusing on biocompatibility, food safety, and scalability.
• To provide a framework for designing next-generation edible scaffolds by evaluating component roles.

Main Methods:

• Systematic evaluation of naturally derived gel-forming polymers (gelatin, chitosan, cellulose, alginate, plant proteins).
• Analysis of food-grade functional additives (nanocellulose, dietary fibers, polyphenols, transglutaminase).
• Focus on compositional design and material properties rather than fabrication methods.

Main Results:

• Naturally derived polymers and food-grade additives can form hybrid hydrogel scaffolds.
• These scaffolds enhance mechanical stability, rheological properties, and cell guidance.
• Material-centric design strategies are key for scalable, printable, and digestible scaffolds.

Conclusions:

• Hybrid gel-based scaffolds are foundational for cultured meat functionality, manufacturability, and consumer readiness.
• Addressing challenges in structural optimization, regulatory validation, and scale-up is critical.
• This food-centric approach bridges biomaterials science and food engineering for practical cultured meat realization.
