Scaffold Biomaterials in the Development of Cultured Meat: A Review

Area of Science:

• Biomaterials Science
• Food Technology
• Cellular Agriculture

Background:

• Conventional meat production poses environmental and food security challenges.
• Scaffolds are crucial in cultured meat production for cell support and development.
• Biomaterial selection significantly impacts cultured meat's texture, flavor, and quality.

Purpose of the Study:

• To provide a comprehensive review of biomaterials used in cultured meat scaffolds.
• To critically analyze the strengths and limitations of various biomaterial sources.
• To guide scaffold fabrication strategies and explore potential applications.

Main Methods:

• Literature review of biomaterials from animal, plant, algae, and microbial sources.
• Analysis of biomaterial properties, including cell adhesion, proliferation, and differentiation support.
• Evaluation of mechanical strength, biocompatibility, cost, and biodegradability.

Main Results:

• Animal-derived biomaterials offer good biocompatibility but are costly and mechanically weak.
• Plant-derived biomaterials are cost-effective but require modification for enhanced properties.
• Algae-derived materials offer gelling but lack cell-binding sites; microbial-derived materials offer strength but lack nutrition.
• Each biomaterial type presents unique advantages and disadvantages for scaffold fabrication.

Conclusions:

• Optimizing cultured meat production requires careful selection and strategic use of diverse biomaterials.
• Leveraging the unique properties of each biomaterial source is essential for designing effective scaffolds.
• Further research into material modification and combination is needed to overcome limitations and enhance cultured meat quality.
