In Vitro Stability and Lipid-lowering Activity Analysis of Liposome/Gum Arabic Nanoparticles Loaded with Anthocyanins

Abstract

To address the issues of low bioavailability, degradation during processing, and limited use in precision nutrition of anthocyanins (ACNs). ACNs nanoparticles using ACNs as the core, soybean lecithin constructed-Liposome (Lipo), and Gum Arabic (GA) as the carrier were prepared in this study, namely Liposome/Gum Arabic-anthocyanins (Lipo/GA-ACNs) nanoparticles. In this study, nanoparticles of ACNs with ACNs as the core and liposomes (Lipo) constructed using soy lecithin and gum arabic (GA) as carriers, namely liposome/gum arabic-anthocyanins (Lipo/GA-ACNs) nanoparticles, were prepared. Environmental factors and in vitro simulated digestion on the stability of Lipo/GA-ACNs nanoparticles with various formulations were investigated. Additionally, the in vitro lipid-lowering activity of Lipo/GA-ACNs nanoparticles after digestion was examined. Results showed that Lipo/GA-ACNs nanoparticles had good stability under simulated thermal processing and different ion environments. When the ACNs to GA mass ratio was 1:10, the Lipo/GA-ACNs nanoparticles inhibited lipid droplet accumulation and reactive oxygen species accumulation in HepG-2 cells 3.8% and 1.99% more effectively than ACNs after simulated digestion. This study concluded that Lipo/1.0GA was a promising oral delivery system to deliver ACNs and achieve liver lipid-lowering, with the potential to be developed into functional foods with precision nutritional properties.
