Anti-microbial Technology

Extending shelf life of perishable goods without altering the fruits and vegetables is a challenge. CSP has an innovative solution which enables seamless integration of its antimicrobial technology into packaging to significantly extend shelf life. The unique formulations based on its patented Activ-PolymerTM technology can be customized to meet the requirements of the product and packaging sizes.

CSP anti-microbial solutions were developed by incorporating new patent-pending active compounds into the CSP Activ-PolymerTM technology platform.

CSP is able to characterize the interaction between the headspace and the packaged product. Then design the packaging  system and the release profile to optimize the efficacy of the anti-microbial agent while maintaining the organoleptic properties of the food.

Samples of sliced tomatoes were inoculated with Listeria, Salmonella and E.coli, sealed in plastic trays and stored at 8゚C.  In each case, there was a significant reduction of the pathogens.

In addition, sliced tomatoes were inoculated with the mold Geotrichum Candidum, a yeast-like mold that grows as a white fuzz. Samples were packaged in sealed plastic trays and stored at 4゚C for 14 days.
