Double-encapsulated modified silica/nanocellulose composite film with cherry preservation.
Ordinary nanocellulose films suffer from poor barrier properties, rendering them ineffective at preventing microbial invasion of food. Herein, double-embedded modified silica/copper nanoparticles/E2H preservative (NE) was obtained by in-situ immobilized copper nanoparticles (CuNPs) and simultaneously loading trans-2-he...
