Nanoparticles were synthesized for the first time from pea protein isolates using ethanol desolvation followed by high-pressure homogenization. Size of the pea protein nanoparticles (PPN) was tailored by controlling the pH, changing the ethanol to water ratio, and pre-heating the dispersion before desolvation. PPN showed smaller size and higher surface charge at pH 10 than at pH 3. Pre-heating the protein solutions also increased surface charge of the PPN compared to that fabricated at room temperature. Desolvation led to a roughly spherical shape and extensive aggregation of PPN. A change in protein secondary structure, such as decrease in β-sheet, and an increase in α-helix and random coil, was also recorded. View this paper.
