Summary
This 2024 laboratory study investigated how ultrasound and high-pressure assisted extraction optimise the functional and digestibility properties of pearl millet protein isolate. As suggested by the experimental design, the research compared extraction techniques to identify methods that enhance protein bioavailability and structural suitability for food applications. Pearl millet, a neglected cereal crop, may represent an under-utilised source of plant-based protein, and optimised extraction could improve its nutritional application in food systems.
Regional applicability
Pearl millet is not widely cultivated in the United Kingdom; the findings would be most directly applicable to regions where pearl millet is a staple or emerging crop (principally Africa and South Asia). However, the extraction methodology and protein optimisation principles could inform UK food manufacturers seeking alternative plant-based protein sources for formulation.
Key measures
Protein isolate functional properties (likely emulsification, foaming, water/oil binding capacity); in vitro digestibility; protein structural characteristics (likely molecular weight distribution, amino acid profile, secondary structure)
Outcomes reported
The study examined how ultrasound and high-pressure assisted extraction techniques affect the functional properties, digestibility, and structural characteristics of pearl millet protein isolate. The research compared extraction methods to identify approaches that optimise protein bioavailability and functional suitability for food formulation.
