Antimicrobial Biopolymer for Food Preservation

Filed in archive Food and Agriculture on August 29, 2007

Scientists have developed a biodegradable polymer with food-sourced antimicrobial agents, designed to prevent the formation of bacterial biofilms on food surfaces and packaging. The natural antimicrobial agents were developed from sources such as cloves, oregano, thyme and paprika, and are said to be more effective against a broader spectrum of microorganisms than organism-specific drugs.

"As they degrade in the presence of water and/or enzymes, they slowly release their active antimicrobials," Carbone explained. "A slow and controlled release of the food-based antimicrobial would offer great advantages in the food industry, providing protection over an extended time and extending the shelf life of the product."

The researchers said these polymers could offer a natural alternative to chemicals used to protect food against contamination and spoilage.
