Improved Produce Freshness and Shelf Life Now Available Through Chlorine Dioxide Distribution Deal

Share Article

Selective Micro Technologies signs exclusive Southeast distribution deal with Highland Corporation for Selectrocide™ – a new generation of chlorine dioxide products for the food processing industry.

Food processors across the Southeast can improve the quality and extend the shelf life of certain fruits and vegetables because of a distribution deal announced today between Selective Micro Technologies and Highland Corporation.

Under terms of the agreement, Highland Corporation will distribute Selectrocide™ chlorine dioxide products, which enable food processors and handlers to extend shelf life of fruits and vegetables by reducing spoilage microorganisms on raw agricultural commodities (RACS) in food processing facilities.    

Chlorine dioxide is one of the most effective inhibitors of spoilage microorganisms, yeast and mold, all of which cause fruits and vegetables to decay. Because of its selectivity as an oxidizer and its efficacy at low concentrations, Selectrocide chlorine dioxide prevents decay for a longer period than do many other biocides.

“Our trial programs have shown significant benefit on a variety of fruits and vegetables,” said Johnny Harden, Chief Operating Officer of Highland Fresh Technologies. Harden added, “Chlorine dioxide is the most unique biocide in the world, and we look forward to helping growers work the Selectrocide line of products into all phases of post-harvest processing.”

“Highland has the potential to save thousands of customers millions of dollars by increasing the shelf life of fresh produce,” said Richard Hamilton, chief food scientist, Selective Micro Technologies.    

Background Information on Chlorine Dioxide and Selectrocide™

Chlorine dioxide is effective at low concentrations across a wide range of pH (roughly 4 to 10), and, because it is a gas in its natural state, dissipates upon exposure to sunlight. As a consequence, it is known widely as one of the most effective inhibitors of algae, yeast, mold, and fungi. However, because transporting the gas is generally prohibited in all but frozen forms, pure chlorine dioxide has heretofore been limited to use in large concerns that employ chemical generators, such as pulp mills (controlling slime) and municipal water systems (water purification applications). For antimicrobial applications, pure chlorine dioxide has been unavailable to organizations without chemical generators. With Selectrocide, the advantages of nearly pure chlorine dioxide (which differs markedly from the “stabilized” solutions and acidified sodium chlorite solutions on the market) are available for the first time.

Just add water—and wait. Now, Selectrocide™ brings the power of nearly pure (greater than 99%) chlorine dioxide solutions to point-of-use applications. Selectrocide™ produces chlorine dioxide simply by submersing the product in water. The resulting chlorine dioxide solution can be used to inhibit or kill a broad range of microbes, yeasts, molds, fungi and algae using spraying, washing or “dip” cleaning methods. Selectrocide™ makes it possible–for the first time–to generate specific concentrations of chlorine dioxide at the point of use, at neutral pH and with very low residuals, using only tap water.

The Selectrocide™ Family of Products—One-Stop Supplier for Processing Needs

In addition to produce shelf-life and freshness extensions for raw agricultural products in food processing facilities, Selectrocide™12G is registered with the US EPA as a disinfectant and sanitizer for applications against common public-health pathogens on hard, non-porous surfaces, and can improve hygiene throughout processing facilities when used as directed.

A separate line of Selective Micro’s products, Selectrocide™A-10 and A-15, are designed specifically for fresh-cut produce applications. Hamilton noted, “In field trials, Selectrocide reduced bacteria, yeast, and mold on fresh-cut fruit to low levels thereby maintaining taste and appearance and extending shelf life up to 14 days in some cases.”

All of Selective Micro’s products generate a 500-ppm solution that is diluted in turn to the application-specific concentration. To view the recommended dilutions and use concentrations, by application, please see the attached graph.

Summary of Selectrocide™ Benefits

  •     Extends shelf life and freshness of non-processed fruits and vegetables. Produce stays fresh longer.
  •     Reduces levels of pathogenic and other microorganisms on hard, non-porous food-contact (and non-food contact) surfaces, enhancing food safety programs throughout post-harvest operations. Pathogens and other organisms cannot build up resistance to Selectrocide™ because it kills harmful organisms by breaking down cell walls.
  •     Reduces spoilage and pathogenic microorganisms on processed, fresh-cut fruits and vegetables (Selectrocide™ A-10 and A-15 only)
  •     Easy to use and does not require HAZMAT or complicated equipment
  •     Can be made on-site in specific quantities and in concentrations desired. Only tap water is required to generate the chlorine dioxide.
