Enhancing pea protein isolate functionality: A comparative study of high-pressure homogenization, ultrasonic treatment, and combined processing techniques

Eco-Friendly Electrospun Nanofibers Based on Plant Proteins as Tunable and Sustainable Biomaterials

“…The CD spectra of PEA-72% and SOY-72%, show a broad negative peak in the range of 210−240 nm, indicative of a high inter-molecular β-sheet content, 73,74 which is in accordance with the secondary structure of the proteins within the nanofibers in the solid state and indicates that after disintegration the samples of PEA-72% and SOY-72% nanofibers contained a large amount of aggregated proteins. Similarly, a high β-sheet content has previously also been reported for soy 16,75 and pea 76 protein isolate powders in solution.…”
