RF Pasteurization Low Moisure Food Safety

Is food processed by RF heating safe to consume?

RF waves, similar to microwave, are non-ionizing radiation since the frequencies in the RF range cannot produce sufficient energy to ionize molecules in foods such as water, unlike higher levels of energy such as X rays and Gamma rays which can change molecular structures. RF is therefore regarded as a safe treatment for edible food products. RF and microwave treatments also meet organic labeling standards which are more acceptable to consumers (Mitcham et al., 2004).
