Physicochemical properties of gelatin films containing tea polyphenol-loaded chitosan nanoparticles generated by electrospray
In this study, gelatin (GEL) extracted from grass carp and tea polyphenols (TP) were encapsulated in chitosan (CS) nanoparticles using an innovative electrospray based ionic gelation method. CS-TP nanoparticles were fully optimized in terms of encapsulation efficiency and polydispersity. The average...

| description | In this study, gelatin (GEL) extracted from grass carp and tea polyphenols (TP) were encapsulated in chitosan (CS) nanoparticles using an innovative electrospray based ionic gelation method. CS-TP nanoparticles were fully optimized in terms of encapsulation efficiency and polydispersity. The average diameter of the optimal CS-TP nanoparticles was 205 ± 14 nm, and encapsulation efficiency of 66.7% ± 9.9% was achieved. The effects of CS-TP nanoparticles on the physicochemical properties of the GEL/CS-TP composite films were studied. Our results showed that the combination of CS-TP and grass carp gelatin (GEL) can not only weaken the strong interaction between GEL and TP, but also improved the swelling and mechanical properties of GEL. Furthermore, GEL/CS-TP30% composite film showed strong barrier and good mechanical properties, low UV transmission, exhibited high free radical-scavenging ability and prolonged the stability of an easily oxidizable oil for over 14 days, making it a suitable film for use as an edible packaging material.
