Abstract
Anthocyanins (ACNs) systems encapsulated in nanomaterials have received widespread attention and rapid development due to its good delivery potential. Here, the favorable benefits of four natural polysaccharide food additives coated ACNs-liposome nanoparticles (ACNs-Lipo NPs) on the stability and possible lipid-lowering effects of ACNs are discussed in this work. The polysaccharides were coupled to the ACNs-Lipo NPs and self-assembled to create ACNs-Lipo@polysaccharide NPs. The impact of various polysaccharides on the physical, chemical, and stability characteristics of NPs was examined. We found that the NPs prepared with gum arabic (GA) had the best stability. FT-IR and XRD analysis revealed electrostatic adsorption and hydrogen binding forces between the components, as well as an amorphous structure. A series of tests in vitro confirmed the excellent stability, bioavailability, antioxidant activity, and biocompatibility of NPs. Finally, cellular antioxidant activity (CAA) and oleic acid (OA)-induced lipid deposition cell models revealed that ACNs-Lipo@GA might be more readily absorbed by cells, resulting in improved antioxidant activity and lipid-lowering impact, with possible targeted delivery qualities and lipid-lowering effect.
