Abstract Pumpkin seed protein isolate (PSPI) was enzymatically hydrolyzed by alcalase and pepsin to obtain H1 and H2 hydrolysates, respectively. Influence of enzymatic hydrolysis on solubility, interfacial and emulsifying properties of PSPI was investigated as a function of pH (3–8) and ionic strength (0–1 mol/dm 3 NaCl). Solubility of PSPI was lowest at pI = 5. Solubility of both hydrolysates was higher than solubility of PSPI, especially at pH close to pI. Increase in ionic strength brings… Expand

Effects of Enzymatic Hydrolysis of Fava Bean Protein Isolate by Alcalase on the Physical and Oxidative Stability of Oil-in-Water Emulsions
Fava bean protein isolate hydrolysates with DH of 4% had suitable molecular weight for better interfacial layer stability, increased surface net charge for more repulsive electrostatic force, and increased hydrophobicity for better adsorption at the interface and, therefore, may serve as potential natural emulsifiers to maintain both physical and oxidative stability of O/W emulsions.
