Curcumin-loaded carboxymethyl cellulose/sodium alginate films with enhanced solubility and bioactivity for freshness monitoring of fish and beef.
Intelligent active food packaging films were developed by enhancing curcumin solubility through 2-hydroxypropyl-β-cyclodextrin inclusion complexes (EC). EC was incorporated at varying concentrations into a carboxymethyl cellulose (CMC)‑sodium alginate (SA) matrix. Sedimentation tests revealed that free curcumin exhibit...
