A Review on the Application of Animal-Based Materials Using Three-Dimensional (3D) Printing and Protein Restructuring...

Area of Science:

• Food Science and Technology
• Biotechnology
• Sustainable Agriculture

Background:

• Growing demand for alternative proteins necessitates innovation in food production.
• Current meat analogs often lack the desirable sensory attributes of conventional meat.
• Technological advancements are key to improving the quality and consumer acceptance of plant-based alternatives.

Purpose of the Study:

• To explore the synergistic potential of extrusion molding and 3D printing for enhanced meat analog production.
• To improve the texture, juiciness, and overall sensory experience of alternative protein products.
• To develop sustainable methods for creating future protein resources.

Main Methods:

• Utilizing high-moisture extrusion to organize vegetable proteins and mimic meat fiber structure.
• Employing three-dimensional (3D) printing for precise arrangement of muscle fibers and adipose tissue simulation.
• Integrating fat analogs and other components through 3D printing to enhance marbling and appearance.

Main Results:

• Extrusion successfully replicated meat-like textures and fiber structures.
• 3D printing enabled sophisticated control over the arrangement of components, simulating muscle and fat.
• The combined technologies showed potential for significantly improving the organoleptic properties of meat analogs.

Conclusions:

• The combination of extrusion and 3D printing offers a promising pathway for producing high-quality, sustainable meat alternatives.
• These advanced manufacturing techniques can bridge the gap between plant-based options and consumer expectations for sensory satisfaction.
• This integrated approach contributes to the development of future protein resources, balancing environmental sustainability and food security.
