Nonmeat Protein Alternatives as Meat Extenders and Meat Analogs

Area of Science:

• Food Science
• Nutritional Science
• Biotechnology

Background:

• Growing demand for plant-based proteins driven by animal disease concerns, protein shortages, and consumer preferences for wholesome, halal, and economical food options.
• Legume and oilseed proteins are vital for functional foods due to high protein content, though antinutrients present utilization challenges.
• Antinutrients can be mitigated through processing, and some possess health benefits; plant proteins complement cereals for balanced amino acid profiles.

Purpose of the Study:

• To review the molecular, nutritional, and functional properties of alternative protein sources.
• To summarize current knowledge on vegetable proteins and mycoprotein as meat substitutes.
• To encourage further research for optimizing alternative protein benefits.

Main Methods:

• Literature review of scientific articles on alternative protein sources.
• Analysis of nutritional and functional properties of plant-based proteins and mycoprotein.
• Evaluation of processing techniques for antinutrient reduction and protein modification.

Main Results:

• Texturized vegetable proteins (TVPs) derived from soybean, wheat gluten, and cottonseed are used to extend meat products or as meat analogs, valued for their low cost, texture, and cholesterol-free profile.
• Mycoprotein, a fungal protein, is a high-protein, low-fat, health-promoting ingredient with good taste and texture.
• Both TVPs and mycoprotein products are accepted as halal foods, meeting diverse consumer needs.

Conclusions:

• Alternative protein sources like TVPs and mycoprotein offer viable, nutritious, and functional substitutes for meat.
• Processing plays a key role in overcoming challenges like antinutrients and enhancing the appeal of plant-based proteins.
• Further research is needed to fully leverage the potential of these alternative proteins for improved food products and health outcomes.
