The
following is a summary of our tests using your electrode generated copper ions and its bacterial, yeast and mold reduction
on tomatoes:
Purpose of Study
The purpose of the study was to determine the antimicrobial effects of Agri
Ionization Systems electrolytic generated copper ions on the tomatoes.
Results
Initial experiments have revealed
an approximate 2 log reduction in total bacteria on the surface of the tomatoes that were exposed for 5 minutes at a copper
concentration 0.5-1.0 mg per liter. In addition, yeast and molds were reduced approximately 1 log using identical conditions.
Conclusion
In conclusion, results thus far indicate a significant reduction of 2 logs (100 to 1 reduction)
in surface bacterial and at least a 1 log reduction in surface yeast and molds associated with tomatoes. Further experiments
are in progress.
