Antimicrobial and antioxidant films made from potato waste

University of Alberta researchers have developed a starch-based plastic film that has antioxidant and antimicrobial properties using potato peels and culls considered waste by Alberta’s potato-processing industry.
Currently, the team is testing antimicrobial activity. The next step is to test the films on packaging of ready-to-eat meat. With international interest on whether the subcritical method would also work on cassava (the starchy root of a tropical tree), the team is also studying that possibility. Another researcher is looking at adding nanoparticles on the films so that more antioxidants/antimicrobials could be added to the film (News Article University of Alberta, 27 October 2015).
