Radio Frequency Company (Millis, MA) has announced its Macrowave RF (radio frequency) pasteurization systems have been fully validated for the treatment of rice flour utilized in infant formula achieving a greater than 5 log reduction of microbes including salmonella, E. coli and listeria.
The unique structure of the “polar” water molecule, is the basis for the thermal response of water when subjected to an alternating RF energy field. In a Radio Frequency Pasteurization System, the RF generator creates an alternating electric field between two electrodes, above and below the conveyor. This alternating electric field causes the product to heat rapidly and uniformly throughout the entire thickness of the product whether it is in bags, or loose on a troughed conveyor. Simple, Easy to clean, and very effective. Infant Formula Baby Formula
Key Benefits for utilizing RF Pasteurization for Dry Ingredients:
- RF Volumetric Heating means there is no temperature differential from the surface to center, and no prolonged soak time which could be damaging to protein functionality.
- A Short Heating Cycle allows the product to maintain protein functionality, and other organoleptic and nutritional qualities.
- The Rapid Temperature Rise reduces the ability for microbes to acclimate themselves to defend against high temperatures.
