RF Pasteurization Stops Production of Dangerous Aflatoxins

RF Pasteurization Stops Production of Dangerous Aflatoxins

Radio Frequency (RF) pasteurization of cereal grains provides a 5 log reduction (CFUs) of aspergillus molds and stops their production of dangerous aflatoxins.


Aflatoxins are poisonous carcinogens and mutagens produced by both {aspergillus flavus} and {aspergillus parasiticus,} which are common forms of ‘weedy’ molds widespread in nature. The presence of those molds does not always indicate that harmful levels of aflatoxin are present, but does indicate a significant risk. When the molds can colonize and contaminate food grains during storage, aflatoxin levels will increase, often above regulated limits. Also, organic crops, which are not treated with fungicides, may be more susceptible to contamination with aflatoxins. (1)


RF pasteurization is a thermal process caused by a “non-ionizing” electromagnetic form of energy, just like an FM radio transmitter. The USDA does not view the RF thermal process as an added ingredient. Therefore an organic product treated with RF can carry the certified organic label.



Additionally, the FDA does not view the RF thermal process as invalidating the application of “natural” on the label, unlike irradiation (an ionizing form of radiation), which is considered an additive, and therefore requires approval and special labeling.


Complete turn-key systems are available in a complete size range from Radio Frequency Company for both bulk flow and bagged product.
