The Sustainable Development Goals 12 (SDG12) of the United Nations deals with responsible consumption and production. It highlights the importance of sustainable production and consumption. There is an urgent requirement to bring the non-conventional sources of food under the umbrella of mainstream food chains to meet the demand of the growing population sustainably. Proteins are one of the important nutrients required in human nutrition to maintain the well-being of consumers. The production of proteins from plant sources is considered environment friendly when compared with that of production from animal counterparts. Therefore, the demand for plant-based proteins is rising, the rising demand for plant proteins and their products has to be met without significantly increasing the “carbon footprints”. To achieve and ensure the success of the SDGs, appropriate steps must be taken to bring non-conventional sources of proteins which may include underutilized crops, and food wastes/ by-products generated in the agri-food sector for extraction, isolation, value addition, and valorization.  In the present global scenario, the sustainable utilization of non-conventional plant sources to produce value-added products for potential applications in the food, pharmaceutical, or cosmetic industries can provide additional income opportunities. To explore the potential of these non-conventional sources the studies on the extraction, chemistry, and utilization of plant proteins from non-conventional sources need to be taken under the umbrella of research to highlight the untapped proteins present in these otherwise underutilized and or wasted sources. In this context, the availability of novel technologies along with sustainable methods to characterize, and study the chemistry of plant proteins is very much timely.


This Research Topic will try to explore the novel methods being used across the globe for extraction and collect all information in one place to make it easier/ available to researchers, readers, industry, and academia for future research.

Extraction, Chemistry, and Utilization of plant proteins from non-conventional sources: A Scientific Approach Towards their utilization

Topics of interest for the special issue include, but are not restricted to the following areas:


Utilization of Novel Extraction techniques for extraction of plant proteins from non-conventional sources:
• Pressure-based extraction technologies.
• Electric-field-based extraction technologies.
• Pulsed electric field extraction.
• Ultrasound-assisted extraction.
• Supercritical carbon dioxide extraction.
• Novel thermal extraction technologies.

  • Characterization of recovered proteins from non-conventional sources using novel extraction methods
  • Energy and recovery-based performance evaluation of the novel protein extraction method/s

Screening and quantification of the plant proteins using advanced techniques:
• Chromatography-based characterization of recovered plant proteins from non-conventional sources.
Physicochemical, antioxidant, and therapeutic properties of plant proteins:
• Emulsion, surface, and rheological characteristics of the plant proteins recovered

  • Antioxidant and anti-carcinogenic properties of the plant proteins recovered

Novel delivery systems active ingredients:
• Protein-based delivery systems.
• Interaction of extracted plant proteins with other components of the delivery system.
• Stability of the plant proteins in the delivery system, stability evaluation based on the in-vivo and in-vitro studies.

Utilization of plant proteins in the development of novel functional foods and to study their impact on food quality and safety:
• Application of plant proteins in food formulation and ingredients.
• Application of plant proteins in food products such as bakery, dairy, meat, and poultry.
• Stability of plant proteins during processing.
