The protein powder concentrate obtained by SIUS reached a protein content of ∼ 72 % (dry weight, DW), under the optimized conditions of amplitude: 48 %, solvent/sample ratio: 50 mL/g and time: 19 min at pH 10.5, compared to that obtained using the conventional method with ∼77 % (DW). The physicochemical and structural characteristics differentiate both protein concentrates, the SIUS protein presented a slightly darker color, a narrower size particle distribution, a higher specific surface area, and a manifest denaturation as evidenced by the thermal analysis, compared to that obtained for SIC protein. The structural modifications of the proteins were evaluated by FTIR and circular dichroism (CD) spectroscopy, FTIR showed that the total proteins in SIUS had a decrease in β-sheet and an increase in β-turn configuration, whereas the soluble proteins evaluated by CD presented a marked decrease in α-helix and an increase in random coil and β-sheet configurations. The results contribute to offering information for future applications for both protein concentrates from SI cake in the food sector.Item Conventional and ultrasound-assisted extractions of protein from sacha inchi (Plukenetia volubilis) and their impact on the physicochemical and structural characteristicsChirinos, Rosana; Scharff-Salinas, Romina; Rodriguez-Diaz, Jamerccy; Figueroa-Merma, Andrés; Aguilar-Galvez, Ana; Guzmán, Fanny; Contardo, Ingrid; Pedreschi, Romina; Campos, DavidItem Designing a gelatin/chitosan/hyaluronic acid biopolymer using a thermophysical approach for use in tissue engineeringEnrione, Javier; Díaz-Calderón, Paulo; Weinstein-Oppenheimer, Caroline R.; Sánchez, Elizabeth; Fuentes, Miguel A.; Brown, Donald I.; Herrera, Hugo; Acevedo, Cristian A.Item Desnutrición(Alarcón, Paula) Alarcón, PaulaItem DM: Complicaciones crónicas(Bofill, Gabriela) Bofill, GabrielaItem Edible scaffolds based on non-mammalian biopolymers for myoblast growthEnrione, Javier; Blaker, Jonny J.; Brown, Donald I.; Weinstein-Oppenheimer, Caroline R.; Pepczynska, Marzena; Olguín, Yusser; Sánchez, Elizabeth; Acevedo, Cristian A.Item Effect of Extrusion Temperature and Feed Moisture Content on the Microstructural Properties of Rice-Flour Pellets and Their Impact on the Expanded ProductZambrano, Yadira; Contardo, Ingrid; Moreno, María Carolina; Bouchon, PedroItem Effect of physical state of gelatin-plasticizer based films on to the occurrence of Maillard reactionsRiquelme, N.; Díaz-Calderón, P.; Enrione, J.; Matiacevich, S.
