Antimicrobial food packaging system based on ethyl lauroyl arginate-loaded core/shell electrospun structures by using hydrophilic and hydrophobic polymers

Antimicrobial compounds can be encapsulated into core/shell structures through coaxial electrospinning in order to develop novel active food packaging materials. In this work, poly (vinyl alcohol)-(ethyl lauroyl arginate)/poly (lactic acid) core/shell fibers, (PVOH-LAE/PLA)f, were developed with the...
