PPI was characterised using thermogravimetric methods coupled with evolved gas analysis, differential scanning calorimetry, and X-Ray powder diffraction. As water is an integral component in determining protein properties, inelastic neutron scattering was further used to study water populations in the PPI powder. Hydration time was identified as key in determining solubility. Heat treatment resulted in partially denatured, more soluble, less thermodynamically stable, and less crystalline PPI compared to the control. Heating, often associated with protein aggregation and particle size increase, was found to reduce PPI particle sizes, which was attributed to the disruption of non-covalent interactions. During emulsification, these features enhanced formation of smaller drops, stable against coalescence. Compared to the control, the heat-treated PPI produced emulsions with increased shear thinning (power law index of 0.6 compared to 0.9) and consistency (≈10 times higher), as it has been previously reported for emulsions with fine, compared to coarse, droplets. Acid-induced gels of the heat-treated PPI were ≈4 times more elastic (G’) compared to the control.

The particle size, zeta-potential, and surface wettability of ZPNPs with different zein-to-pectin mass ratios were systematically evaluated.

This work aimed to investigate the structural changes and improve functional properties of ultrasound treated camelina protein isolate (CPI). Structural analysis revealed that ultrasonic treatment did not change the molecular weight distribution of CPI, but increased the content of β-sheet. Moreover, the tertiary structure of CPI was altered under ultrasonic treatment with the tryptophan partially exposed to a polar environment characterized by intrinsic fluorescence spectra. Additionally, under ultrasonic treatment of 15 min, the particle size was reduced by 43%, the surface area between protein and water was increased, and the solubility of CPI was enhanced by 42%. Ultrasonic treatment exposed the positively charged groups inside the protein, increasing the zeta potential (from − 14.9 mV to -9.7 mV). Furthermore, the H<sub>0</sub> was increased due to the destruction of hydrophobic interactions in the protein molecule by ultrasonic treatment, allowing the internal hydrophobic groups to be exposed. As a result, this reduced the hindrance at the air-water interface, increasing the adsorption rate, and improving the emulsifying and foaming properties. The foaming ability of CPI reached 202% at 35 min of ultrasound, which was 1.32 times that of untreated CPI. The foaming stability was best at 25 min. The emulsifying activity index increased from 10.87 m<sup>2</sup>/g to 14.09 m<sup>2</sup>/g, and the emulsifying stability index reached the highest value at 5 min.
