The samples were stored at 4 °C, 10 °C or 22 °C, and the levels of aerobic bacteria were evaluated twice a week over a four-week period.
The researchers found that packaging with an oxygen scavenger or a carbon dioxide generator was effective at reducing bacterial growth. However, the packaging with an allyl isothiocyanate (AIT) generator was less effective.
According to researchers, antimicrobial packaging is one of the most promising applications of active food packaging technology as it controls spoilage as well as contamination by pathogens.
