Proteins from Legumes, Cereals, and Pseudo-Cereals: Composition, Modification, Bioactivities, and Applications

Area of Science:

• Food Science
• Nutritional Science
• Biochemistry

Background:

• Growing environmental concerns associated with animal protein production necessitate sustainable alternatives.
• Plant-based proteins are increasingly recognized for their potential to meet global protein demands.
• Understanding plant protein characteristics is crucial for their effective utilization in food systems.

Purpose of the Study:

• To comprehensively review plant-based proteins from diverse botanical sources (soybeans, pulses, cereals, pseudo-cereals).
• To analyze their structural properties, modification techniques, bioactivities, and food applications.
• To compare nutritional profiles, digestibility, environmental impacts, and consumer acceptance.

Main Methods:

• Literature review synthesizing research on plant protein structure-function relationships.
• Analysis of modification techniques to improve plant protein functionality.
• Investigation of bioactive properties and applications in novel food products.

Main Results:

• Plant proteins exhibit significant diversity in composition, nutritional value, and digestibility.
• Innovative modification techniques can enhance functional properties like emulsification and gelation.
• Plant proteins possess bioactivities (antioxidant, antimicrobial) and are applicable in meat analogs, dairy alternatives, and baked goods.

Conclusions:

• Plant proteins are sustainable, nutritious, and functional ingredients with broad food applications.
• Overcoming sensory and functional challenges is key to improving consumer acceptance and marketability.
• Further research is needed to optimize the utilization of plant proteins in the food industry.
