Development and characterization of carrageenan/grapefruit seed extract composite films for active packaging

Researchers at Mokpo National University in the Republic of Korea developed carrageenan-based antimicrobial films by incorporation of grape fruit seed extract (GSE) at different concentrations into the polymer using a solvent casing method and examined their physical, mechanical, and antimicrobial properties.
The carrageenan/GSE composite films exhibited great antibacterial activity against food borne pathogens. These results suggest that the carrageenan-based composite films have a high potential for being used as an antimicrobial or active food packaging applications. An article about the research is published in the International Journal of Biological Macromolecules.
