Enzyme-assisted extraction of leaf proteins: efficiency, functionality, and structural insights

Area of Science:

• Food Science
• Biotechnology
• Plant Biochemistry

Background:

• Leaf proteins offer a sustainable and nutritionally valuable alternative protein source.
• Conventional extraction methods often have limitations in efficiency and protein quality.
• Enzyme-assisted extraction (EAE) utilizes enzymatic hydrolysis to improve compound release from plant matrices.

Purpose of the Study:

• To review the application of EAE for green leaf protein extraction.
• To identify optimal process parameters for EAE.
• To compare the characteristics and functional properties of EAE-derived leaf proteins with those from alkaline extraction.

Main Methods:

• Literature review focusing on enzyme-assisted extraction techniques for leaf proteins.
• Analysis of enzyme types (proteases, xylanases, etc.) and their roles in cell wall degradation.
• Comparative evaluation of protein properties based on extraction methods.

Main Results:

• EAE effectively degrades plant cell walls, enhancing leaf protein release.
• Enzyme-assisted extracted leaf proteins exhibit improved functional properties.
• EAE offers a greener alternative to conventional alkaline extraction methods.

Conclusions:

• Enzyme-assisted extraction is a promising technology for high-quality green leaf protein production.
• Optimized EAE parameters can yield leaf proteins with enhanced functional attributes.
• These proteins show potential as functional food ingredients, including additives and nutritional enhancers.
