Alternative Protein Sources as Technofunctional Food Ingredients

Area of Science:

• Food Science and Technology
• Sustainable Food Systems
• Biotechnology

Background:

• Growing global population necessitates sustainable protein sources.
• Alternative proteins (plant, microbial, insect) offer lower environmental impact.
• Limited knowledge exists on these emerging proteins compared to traditional sources.

Purpose of the Study:

• To review the current state of knowledge on alternative proteins and their sources.
• To identify knowledge gaps hindering widespread food industry application.
• To critically assess compositional, structural, and functional properties.

Main Methods:

• Literature review of alternative protein sources (plants, algae, fungi, insects).
• Analysis of protein fractions, environmental behavior, and extraction approaches.
• Evaluation of technofunctional properties (solubility, emulsification, gelation).

Main Results:

• Alternative proteins exhibit diverse properties influenced by source and processing.
• Extraction methods and structuring techniques are key for functional ingredients.
• Meat and dairy analogs can be created using these proteins.
• Consumer acceptance and sustainability data are emerging.

Conclusions:

• Understanding alternative protein properties is crucial for developing functional ingredients.
• Challenges remain in large-scale commercial processing.
• Further research is needed to bridge knowledge gaps for broader application.
