Cold Storage Pome Fruit

Reduce decay, control ethylene, and extend storage life

Food-safety concerns, reducing decay and extending storage life without the dependency of chemicals have increased the demand for safe, proven alternatives such as ozone. With Purfresh’s cold storage solution for pome fruit, packers and processors are able to extend product life, decrease decay and enhance food safety practices naturally.

Cold Storage Pome Fruit

SCIENCE-BASED SOLUTION
Purfresh’s science-based ozone cold storage solution provides a safe and proven alternative for pome fruit packers and processors. Purfresh’s cold storage solution effectively distributes gaseous ozone in the air to kill airborne and surface microorganisms. The solution naturally shuts down the sporulation process and controls ripening by consuming ethylene in storage facilities.

OPTIMUM SAFETY AND EFFICACY
Purfresh’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.
