Use of Chitosan-Based Polyelectrolyte Complexes for Its Potential Application in Active Food Packaging: A Review of Recent Literature

The current challenges in the food packaging field are, on one side, replacing plastic from non-renewable sources with biopolymers and, other hand, generating a material attractive properties for consumer. Currently, consumer is ecologically concerned; industry must think ahead to satisfy their needs. In this context, utilization of polyelectrolyte complexes (PECs) presents itself as an excellent candidate fulfilling these requirements. PECs possess enticing characteristics such encapsulation, protection, and transportation, among others. On diverse types have been used formation PECs, alginate, cellulose, gelatin, collagen, so on. Hence, paper reviews use where chitosan forms complexes.
