Antioxidant and antimicrobial extracts from grape stalks obtained with subcritical water. Potential use in active food packaging development

Vieira-De Freitas, Pedro Augusto; Meyer, Silvia; Hernandez-Garcia, Eva; Rebaque, Diego; Vilaplana, Francisco; Chiralt, Amparo (Elsevier, 2024-09-01)

[EN] In order to valorise winemaking grape stalks, subcritical water extraction at 160 and 180 degrees C has been carried out to obtain phenolic-rich extracts useful for developing active food packaging materials. Red (R) ...
Biodegradable and Antimicrobial PLA-OLA Blends Containing Chitosan-Mediated Silver Nanoparticles with Shape Memory Properties for Potential Medical Applications

Sonseca Olalla, Agueda; Madani, Salim; Muñoz-Bonilla, Alexandra; Fernández-Garcia, Marta; Peponi, Laura; Leones, Adrián; Rodríguez, Gema; Echeverría, Coro; López, Daniel (MDPI AG, 2020-06)

[EN] To use shape memory materials based on poly (lactic acid) (PLA) for medical applications is essential to tune their transition temperature (T-trans) near to the human body temperature. In this study, the combination ...
Bionanocomposite films based on plasticized PLA PHB/cellulose nanocrystal blends

ARRIETA, Marina Patricia; Fortunati, E.; Dominici, F.; López Martínez, Juan; Kenny, J. M. (Elsevier, 2015-05-05)

Optically transparent plasticized poly(lactic acid) (PLA) based bionanocomposite films intended for food packaging were prepared by melt blending. Materials were plasticized with 15 wt% of acetyl(tributyl citrate) (ATBC) ...
