Food-protecting films based on soy protein isolate and natural deep eutectic solvents: Antimicrobial and antioxidant properties
Pablo Mercadal, Matías Picchio , Agustín González
"This #study presents a significant advancement in the synthesis of #SPI #films by incorporating #NADES as #bioactive #agents, specifically tailored for enhancing #food #packaging applications. Despite the inherent hydrophilic nature of these #films, their remarkable resistance to water swelling indicates the successful establishment of a robust crosslinked network between the NADES and SPI components. Notably, our investigation reveals that films containing #ChCl/#TA outperform those having #ChCl/#Cit in terms of tensile strength, underscoring the formation of a more resilient and compact molecular network within the former. The introduction of ChCl/TA NADES produced a larger #plasticizing effect on the films, compared to traditional #glycerol-containing SPI films, which further expands their potential for #flexible #packaging #solutions. Furthermore, the observed reduction in water vapor permeability underscores the dense interlinking between protein chains, accentuating the films' suitability for optimal food preservation. Remarkably, ChCl/TA films exhibit a combination of high opacity and exceptional #antioxidant activity, distinguishing them from ChCl/Cit films. Conversely, ChCl/Cit films display heightened #antimicrobial #efficacy. These findings collectively position these new films as promising candidates for safeguarding light-sensitive and #pathogen-#vulnerable #food items."
