Reduce decay, extend storage life and enhance food safety practices

Food safety concerns, controlling decay and the value of extending product shelf and storage life without the dependency of chemicals has increased the demand for safe, proven alternatives such as ozone. With Novazone’s cold storage and disinfection solutions for potatoes, packers and processors are able to extend product life and marketability, decrease decay losses and enhance food safety practices naturally.

Science-based Solution
Novazone’s science-based ozone solutions for cold storage and disinfection provide a safe and proven alternative for potato packers and processors. Novazone’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 helps control sprouting by consuming ethylene in storage facilities.

Novazone’s spray bar solution dissolves ozone into the water to kill pathogens and controls cross-contamination of a broad spectrum of food- and water-borne microorganisms. Incorporating ozone into the rinse process, growers and processors can control ORP levels, enhance food safety practices and reduce the use of chemicals.

Optimum Safety and Efficacy
Novazone’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.

Compare the Value

	CHLORINE	OZONE
Control of Cross- Contamination	Limited due to required long exposure times	Effective control via short exposure times
Resistance Issues	An ongoing problem	None
Residue on Produce	May adhere to surface or be absorbed into cut ends of product. Leaves stems brown	Ozone reverts to pure oxygen leaving no residue. Preserve green stems
Sensory Aspects of Produce	Salts may burn treated product. Absorption may effect taste and appearance	Ozone maintains fruits taste, texture and smell characteristics
Work Environment	Strong/irritating odors can permeate the work space	Proper system design mitigates any odors
Regulatory Overhead	Increased water discharge costs and scrutiny	None
Corrosiveness	Can corrode equipment	No issue with a properly designed solution

	VARIOUS FUNGICIDES	NOVAZONE
Mold Control	Blue & grey mold; resistant mold strains could build up.	All types of mold; mold is oxidized and cannot become resistant to ozone
Ethylene Control	No	Converts ethylene to water and carbon dioxide (process is outside the fruit)
Residue on Fruit	Yes	No
Taste	No Impact	Natural Flavors Maintained
Dosage / Application	Typically a drench application	Ozone is applied continuously thus controlling mold and ethylene constantly
Regulatory Compliance	Discharge must be hauled away	No EPA record keeping required. Requires fire code compliance
