Microcarriers for Upscaling Cultured Meat Production

Area of Science:

• Biotechnology
• Food Science
• Cell Culture Engineering

Background:

• Industrial meat production faces environmental and animal welfare challenges.
• Cultured meat offers a sustainable alternative but faces scalability issues.
• Microcarriers (MCs) are crucial for upscaling cell culture but require specific design for meat production.

Purpose of the Study:

• To discuss microcarrier design criteria for skeletal muscle cell proliferation for meat production.
• To analyze three bioprocess scenarios involving microcarriers for cultured meat.
• To evaluate the feasibility of a one-step bioprocess using microcarriers.

Main Methods:

• Review and discussion of microcarrier design criteria for muscle stem cells.
• Analysis of three distinct bioprocess scenarios for microcarrier integration.
• Evaluation of microcarrier separation, degradation, and edibility requirements.

Main Results:

• Microcarriers are essential for upscaling muscle cell culture.
• Three scenarios for microcarrier use were analyzed: temporary substrate, degradable substrate, and edible embedded material.
• The edible microcarrier scenario (Scenario 3) shows the most promise for scalable, efficient cultured meat production.

Conclusions:

• Edible microcarriers can streamline cultured meat production by eliminating separation steps and potentially enhancing organoleptic properties.
• Microcarriers designed for edibility offer a versatile approach, usable as temporary or integrated components.
• Further research into edible microcarriers is crucial for advancing sustainable cultured meat production.
