Onions in storage are susceptible to decay, particularly Botrytis neck rot, and black and blue mold rot, from airborne and surface microorganisms and odors can cause unwanted contamination of other commodities. With Ozone International’s cold storage solution, packers and processors are able to control odor crossover, extend product life and marketability, and decrease decay losses naturally. Ozone can be used as a complementary measure with various post-harvest techniques.

Ozone International’s patented science-based cold storage solution generates ozone from the oxygen in the air on-site and delivers defined, low-dose specific concentrations of gaseous ozone into the atmosphere, for use as a powerful but safe disinfectant. The solution kills airborne and surface microorganisms and effectively controls Botrytis neck rot, black and blue mold rot. After killing decay causing microorganisms, ozone immediately reverts to pure oxygen, leaving no residue and maintaining product taste, color, texture and smell characteristics in its natural state.
Ozone International’s unique closed-loop concentration control and remote monitoring capabilities provide optimum safety and efficacy. Its measurement sensors and on-board computer maintains ozone concentrations to within +/- 10 ppb of a desired set point. The solution includes fail-safe ambient air sensors, which constantly ensure work areas maintain ozone concentrations well within OSHA standards. Its remote monitoring service constantly tracks system performance and provides detailed reports and automated alerts.
