Sustained release of lysozyme from zein microcapsules produced by a supercritical anti-solvent process

Delivery systems with sustained release of antimicrobials are possible solutions to minimize the binding between antimicrobials and food matrices, thereby enhancing the efficacy of antimicrobials during shelf-lives of foods. In this work, GRAS (generally recognized as safe) corn zein was used as a carrier material and 90% aqueous ethanol was used as a solvent to microencapsulate GRAS hen egg white lysozyme using a supercritical anti-solvent...
