Biopolymer-coated nanoliposomes as carriers of rainbow trout skin-derived antioxidant peptides

Abstract In this study, an antioxidant peptide fraction with a molecular mass  Oncorhynchus mykiss ) skin gelatin hydrolysates was encapsulated in chitosan-coated nanoliposomes. The mean particle size of liposomal nanovesicles containing PF30 was found to be in the range 163.4–234 nm with a low polydispersity index (PDI  in vitro . Moreover, the chitosan-coated nanoliposomes maintained the antioxidant activity of the PF30 and could be considered a potential candidate for efficient delivery of bioactive compounds in nutraceutical and functional foods.
