Effect of limited hydrolysis of sunflower protein on the interactions with polysaccharides in foams

Rheological properties of protein films

“…Such treatments generally increase the surface activity of the proteins but they may compromise their ability to form coherent films -in general, film viscoelastic moduli decrease as the molecular weight of the adsorbing polymer decreases. However, provided the hydrolysis is limited, the hydrolysates can exhibit higher ε i and foam stabilizing effects than the corresponding native proteins [76][77][78]. The effects of non-adsorbing polysaccharides on the interfacial rheology of adsorbed films formed from protein hydrolysates are naturally different from the effects on the non-hydrolysed protein films, due to different efficiencies of electrostatic bonding between the protein moieties and polysaccharide in the bulk and at the interface [78].…”

Effect of Extraction Procedures on Functional Properties of Eruca sativa Seed Mucilage

“…4 Response surface for the effect of extraction temperature and pH (a, water to seed ratio040:1), and water to seed ratio and pH (b, temperature055°C) on the stability of foam stabilized with Eruca sativa seed mucilage acting as thickening or gelling agents. 26 Therefore, change in the extraction conditions not only alters the viscosity but it will affect the stabilizing effect of extracted mucilage. Mucilage extracted at 52°C, pH of 4.5 and water to seed ratio of 37:1 had the highest foam stabilizing effect (96%).…”

A new way of valorizing biomaterials: The use of sunflower protein for α-tocopherol microencapsulation

“…Vegetable protein hydrolyzates from soybean, pumpkin, sunflower, chickpea and rapeseed have shown various interesting solubility, foaming and emulsifying properties compared to the native proteins (Chabanon, Chevalot, Framboisier, Chenu, & Marc, 2007;Lamsal, Jung, & Johnson, 2007;Martinez, Baezaa, Millan, & Pilosof, 2005;Patino et al, 2007;Vastag, Popovic, Popovic, Krimer, & Pericin, 2010;Yust, Pedroche, Millan-Linares, Alcaide-Hidalgo, & Millan, 2010). The production of hydrolyzed proteins by sequential action of exoprotease is considered an effective way of obtaining protein with defined characteristics (Kong, Guo, Cao, & Zhang, 2008), and alcalase is an endopeptidase used for production of proteins with improved functional and nutritional properties (Junyaprasert, Mitrevej, Sinchaipanid, Broome, & Wurster, 2001).…”
